Proof of optimality of union label & accessories ltdThe proof of the GrahamPollak theorem described by Aigner & Ziegler (2018) (following Tverberg 1982) defines a real variable x i displaystyle x_i for each vertex v i V displaystyle v_iin V, where V displaystyle V denotes the set of all vertices in the graph. Let the left sides and right sides of the k displaystyle kth bipartite graph be denoted L k displaystyle L_k and R k displaystyle R_k, respectively and for any set S displaystyle S of vertices define X ( S ) displaystyle X(S) to be the sum of variables for vertices in S displaystyle S: X ( S ) v i S x i . displaystyle X(S)sum _v_iin Sx_i.Then, in terms of this notation, the fact that the bipartite graphs partition the edges of the complete graph can be expressed as the equation i ------Notable incidents of union label & accessories ltdOn 19 July 1947 at approximately 10:37 AM (MMT), several Burmese independence leaders were gunned down by a group of armed men in uniform while they were holding a cabinet meeting at the Secretariat in downtown Rangoon (present-day Yangon).On 9 October 1983, three North Korean agents attempted to assassinate Chun Doo-hwan, the fifth president of South Korea, by bombing the Martyrs' Mausoleum, where Doo-hwan was commemorating the sacrifice of the Burmese leaders assassinated in 1947. The blast killed 21 people and injured 46.On 7 October 1999, members of the Vigorous Burmese Student Warriors (VBSW) seized the Burmese embassy in Bangkok, Thailand, in an event known as the 1999 Myanmar Embassy siege. Hostages were taken by the VBSW, but all were released without harm after negotiations with Thai authorities. The attackers were later escorted back to Thailand's border with Myanmar.On 30 May 2003 at 8:00 PM (MMT), 70 people associated with the National League for Democracy were massacred by a government-sponsored mob in Tabayin, Sagaing Region, in an event known as the Depayin massacre.On 7 May 2005, simultaneous bomb blasts killed 11 people and injured 162 in Yangon. Authorities blamed Karen and Shan insurgents for the bombings.On 15 April 2010, three separate bombs went off in Yangon during the Thingyan Water Festival, killing 10 people and injuring 178 others in an event known as the April 2010 Yangon Thingyan bombings.In October 2013, a series of unexplained bombings occurred nationwide, resulting in the deaths of three people and multiple injuries.On 9 October 2016, hundreds of insurgents attacked three Burmese border posts along Myanmar's border with Bangladesh, killing nine Burmese border officers. The Arakan Rohingya Salvation Army (then known as "Harakah al-Yaqin") claimed responsibility for the attack, which the government labeled an act of terrorism.On 25 August 2017, up to 150 ARSA insurgents participated in coordinated attacks on 24 police posts and the 552nd Light Infantry Battalion army base in Rakhine State. Twelve members of Myanmar's security forces were killed in the attacks, which the government labeled an act of terrorism.Kha Maung Seik massacre: On 25 August 2017, Hindu villages in an area known as Kha Maung Seik in the northern Maungdaw District of Rakhine State were attacked and 99 Bengali Hindu villagers were massacred, allegedly by insurgents from the Arakan Rohingya Salvation Army. A month later, the Myanmar Army discovered mass graves containing the corpses of 45 Hindus, most of whom were women and children.------Activities of union label & accessories ltdWNUSP has special consultative status with the United Nations. It contributed to the development of the UN's Convention on the Rights of Persons with Disabilities. WNUSP has produced a manual to help people use it entitled "Implementation Manual for the United Nations Convention on the Rights of Persons with Disabilities", edited by Myra Kovary.WNUSP joined with other organizations to create the International Disability Caucus, which jointly represented organizations of people with disabilities and allies during the CRPD negotiations. WNUSP was part of the steering committee of the IDC, which maintained a principle of respecting the leadership of diverse constituencies on issues affecting them, and also maintained that the convention should be of equal value to all persons with disabilities irrespective of the type of disability or geographical location. Tina Minkowitz, WNUSP's representative on the IDC steering committee, coordinated the IDC's work on key articles of the CRPD, including those on legal capacity, liberty, torture and ill-treatment and integrity of the person. Since the adoption and entry into force of the CRPD, WNUSP has worked with other organizations in the International Disability Alliance and its CRPD Forum to guide the interpretation and application of the CRPD on these issues.In 2007 at a Conference held in Dresden on "Coercive Treatment in Psychiatry: A Comprehensive Review", the president and other leaders of the World Psychiatric Association met, following a formal request from the World Health Organization, with several representatives from the user/survivor movement, including Judi Chamberlin (Co-chair of WNUSP), Mary Nettle and Peter Lehmann (Ex-chairs of the European Network of Ex- Users and Survivors of Psychiatry), Dorothea Buck (Honorary Chair of the German Federal Organisation of Users and Survivors of Psychiatry, and David Oaks (Director of MindFreedom International).Salam Gmez and Jolijn Santegoeds are the current Co-Chairpersons of WNUSP.Current International Representative and former co-chair of WNUSP is Tina Minkowitz, an international advocate and lawyer. She represented WNUSP in the Working Group convened by the UN to produce a draft text of the Convention on the Rights of Persons with Disabilities and contributed to a UN seminar on torture and persons with disabilities that resulted in an important report on the issue by Special Rapporteur on Torture Manfred Nowak in 2008.------Charles Manson and Manson Family involvement of union label & accessories ltdIn 1967, at age 19, Fromme dropped out of college and went to Venice Beach after her parents had thrown her out of the house. Suffering from depression, she sat on a curb and watched a bus arrive, and Charles Manson exited. Manson stopped and looked at her and said "Your parents threw you out, didn't they?" Fromme immediately decided Manson was a psychic. Manson walked away and Fromme picked up her belongings and followed him. Manson had recently been released from the federal prison at Terminal Island, and Fromme became the second member of what would become the Manson Family.Fromme found Manson's philosophies and attitudes appealing, and the two became friends and traveled together with other young people, including Mary Brunner and Susan Atkins. She lived with the Manson Family at Spahn Ranch where they worked for their keep, and at the Barker Ranch in Death Valley, which was owned by a Family member's grandmother. Ranch owner George Spahn gave her the nickname "Squeaky" because of the sound that she made when he touched her.Manson and some of his followers were arrested for the Sharon Tate and Leno and Rosemary LaBianca murders in 1969, and Fromme and the remaining Manson Family camped outside the trial. Manson and fellow defendants Atkins, Patricia Krenwinkel, and Leslie Van Houten carved Xs into their foreheads, as did Fromme and her compatriots. They proclaimed Manson's innocence and preached his apocalyptic philosophy to the news media and to anyone else who would listen. Fromme was not charged with involvement in the murders, but was convicted of attempting to prevent Manson's imprisoned followers from testifying, as well as contempt of court when she refused to testify herself. She was given short jail sentences for both offenses.Fromme and Sandra Good moved into a dilapidated attic apartment in downtown Sacramento, as they wanted to be near Manson after he was moved to Folsom Prison. Around 1973, Fromme started work on an extensive 600-page book about the Manson Family, including intricate drawings and photos; other family members had contributed to it as well. Fromme sent it to publishers, but she dropped it after discussing it with Clem Grogan, deciding that the project was too incriminating. The book, titled Reflexion, was eventually published in 2018 by the Peasenhall Press.------Creation and initial development of union label & accessories ltdNUS/UNE was created by students in 1972 as a response to looming post secondary education cuts from the federal government. The federal government instituted a ceiling on Post Secondary Education matching grants to provinces and territories. The prospect of reduced federal transfers for universities, increasing costs, and an all-loan student aid plan proposed by the Council of Ministers of Education, compelled students to reorganize where the Canadian Union of Students had left off in 1969.During 1972, in the province of Ontario, the Ontario Federation of Students (OFS) was organized in response to fee deregulation and tuition increases. A member local of OFS was the University of Windsor Students' Administrative Council, which was pressing for the reorganization of a national student group. In May 1972 an inaugural conference was hosted at University of Windsor in which 26 Canadian university student unions attended. This conference laid the foundation and set the priorities and objectives of a new national student organization, which was very similar to the priorities and objectives of the Canadian Union of Students (NUS/UNE's predecessor organization of the 1960s).On 35 November 1972, the National Union of Students/l'Union nationale tudiants was officially formed in Ottawa by 51 delegates representing student councils and unions from across the country. Notably absent from the NUS/UNE at this time were Qubec students and Atlantic Canadian students as their delegates were reported to have walked out.Between 1973 and 1976, initial policy was formed and finances were organized and solidified in order to consolidate the national student movement. During these years the office was moved from University of British Columbia's Alma Mater Society in Vancouver, British Columbia to Ottawa, Ontario. In 1976/1977 the NUS/UNE was more fully organized and financially stabilized with the Atlantic Federation of Students, British Columbia Federation of Students, Alberta Federation of Students and Ontario Federation of Students, as affiliates, however, their partnership relationship with l'association nationale des tudiants du Qubec (Aneq) was tenuous. The national office of the NUS/UNE employed three staff people and several campaigns were launched. By the end of 1976, NUS/UNE was on firm organizational and financial ground and had by this time launched several nationally coordinated campaigns that involved grass-roots participation at the campus level.

Front-end  Engineering
Front-end Engineering
Front-End Engineering (FEE), or Front-End Engineering Design (FEED), is an engineering design approach used to control project expenses and thoroughly plan a project before a fix bid quote is submitted. It may also be referred to as Pre-project planning (PPP), front-end loading (FEL), feasibility analysis, or early project planning• Other Related Knowledge offront end— — — — — —Front End versus Back EndFront end innovation has been defined into two broad main efforts, the "idea generation effort" which starts the process and "since ideas must be executed in order to generate value, a "back-end" of innovation or "BEI" is required to test and refine the ideas and make them a reality" validation stage. This critical technology discovery and development stage includes locating early-stage technologies, external or internal and testing potential minimum viable product concepts. This step can be achieved via early customer feedback, individually, or from focus groups. Early product trials as well as process concept testing can be completed through test runs on current equipment or equipment owned by others. Based on feedback the effort may be terminated, cleared for insertion into the formal development process, or run through another non sequential innovation cycle. A minimum viable product has just those features that allow the product to be deployed, and no more. The product is typically deployed to a subset of possible customers, such as early adopters that are thought to be more forgiving, more likely to give feedback, and able to grasp a product vision from an early prototype or marketing information. It is a strategy targeted at avoiding building products that customers do not want, that seeks to maximize the information learned about the customer per dollar spent.— — — — — —Compact front end loadersAbram Dietrich Thiessen of Eyebrow Saskatchewan in the 1940s built the first quick attach front end loader. International Harvester's took a picture of the loader and replicated it at the Regina Agribition in November of the same year. Front-end loaders (FELs) are popular additions to compact utility tractors and farm tractors. Compact utility tractors, also called CUTs, are small tractors, typically with 18 to 50 horsepower (37 kW) and used primarily for grounds maintenance and landscape chores. There are 2 primary designs of compact tractor FELs, the traditional dogleg designed style and the curved arm style. John Deere manufactures a semi-curved loader design that does not feature the one piece curved arm, but also is not of the traditional two piece design. New Holland introduced a compact loader with a one piece curved arm on its compact utility tractors, similar one piece curved arm loaders are now available on compact tractors on many brands including Case IH/Farmall, and some Montana and Kioti tractors. Kubota markets traditional loader designs on most of its compact tractors but now features a semi-curved loader design similar to the John Deere loader design on several of its small tractors. While the front-end loaders on CUT size tractors are capable of many tasks, given their relatively small size and low capacities when compared to commercial loaders, the compact loaders can be made more useful with some simple options. A toothbar is commonly added to the front edge of a loader bucket to aid with digging. Some loaders are equipped with a quick coupler, otherwise known as a quick attach (QA) system. The QA system allows the bucket to be removed easily and other tools to be added in its place. Common additions include a set of pallet forks for lifting pallets of goods or a bale spear for lifting hay bales. The tines of a bale spear are three feet long, and sufficiently sturdy to penetrate a county sheriff's side door. LHD (Load, Haul, Dump machine) is also a front end loader but meant to be used for mine compact conditions, can handle various range of loads with varying size of buckets, and can be driven with electric motors as well as diesel engines.— — — — — —Front-end braA front-end bra (also known by other terms such as car bra, bonnet bra, front-end cover, hood bra, auto bra, hood mask, car mask, etc.) is a type of vinyl (usually black) that attaches to the front of a car or other vehicle to protect the bumper, hood, and sides of the fender from scratches. The inside of the bra is lined with a feltlike material. Car bras are considered[by whom?] a 'fashion accessory' to vehicles as their utility is debated and some owners consider that they improve the look of their cars. Others[who?] use a car bra as a way to cover-up light front-end scrapes and damage to their vehicle. It is argued[by whom?] that the vinyl attached can cause damage by retaining moisture, catch air (reducing aerodynamics and causing the fabric to vibrate), as well as cause scratches in paintwork, paint chipping, and other minor damage from rocks, gravel, and other road debris.
How to Set Up a Smartphone for a Child
How to Set Up a Smartphone for a Child
These days, it seems like younger and younger kids are getting smartphones. Even parents who would prefer to wait longer may be tempted, wanting to know that their child is safe during the day - or pressured, wanting their children to fit in. We can not forget, though, that smartphones are fun, portable touch-screen computers. Left to their own devices (no pun intended), children may spend hours playing games and watching YouTube videos. And kids will be kids, perhaps more likely than an adult to break or lose the smartphone. The good news is that we can reduce the risks. As with so many things, it will mainly take a bit of time and ongoing attention, but parental peace of mind is worth it. How to set up your child's smartphone right The settings I will go through are easy to tweak to your own preferences - you can make them as tough or easy as you like, once you know where they are. Let me start with a few basic assumptions, however: Kids play, and that's OK (with limits). The Internet is like the ocean - enticing but also dangerous. Everyone is entitled to a measure of privacy. The two most popular mobile platforms, Apple's iOS and Google's Android, both have built-in parental control tools, but Android lets users adjust more settings than iOS does. Android phones have another attractive quality: They are less expensive and therefore easier to replace. Some people prefer iOS, which may be better for households that have other Apple devices - and for parents who are not concerned about the price. You can read here about how to set up iOS for kids, although it's in the context of tablets and for younger children. Using an Android smartphone requires a Google account, but the terms and conditions stipulate that only a person who is 13 or older can create an account. If you do not already have a second account that you can use for this purpose, you will have to create one. The child does not need to know the password for their new account, and enabling two-factor authentication for it is advisable. Needless to say, the authentication should be linked to your smartphone, not to your child's. Note: You can create an account for your child on devices running Android 7.0 and above by using the Family Link feature, but it is currently available only in the United States. Now, power up the smartphone, add your existing Google account information in the setup wizard, enter your desired e-mail address and other data, enter your age and your phone number, and accept the terms and conditions. If it is not the first time you are starting up the smartphone, you set up the new account here: Settings Accounts Add accounts Google. In the new window, tap Or create a new account. At this point, skip entering payment details for the Google Play store. I will come back to that issue a bit later, but for now I will say that payment information should be linked to an adult's account. That said, we are talking about elementary-school-age children, who are unlikely to need e-mail on their phones. A Gmail account is more likely to collect spam than useful communications, so I recommend not enabling it on the smartphone: Open Settings, go to Google account settings, and uncheck the Sync Gmail option. If a parent is using an Android device too, then creating a family account may make sense. Using a family account lets family members share paid purchases across all of its devices as well as letting a child pay for purchases from their smartphone (using the parent's payment information - and only with the parent's explicit consent). You can create a family account in Google Play from your own smartphone. Launch the Google Play app, open up the menu, and tap on Settings Account Family Manage family members. You can invite your significant other and your children by entering their Gmail addresses on this screen. The invitation has to be accepted from the family member's smartphone. After that, take your smartphone, go to the family group's settings, open the child's profile, and select one of the following modes for purchase approvals: All content, Only paid content, Only in-app purchases, or No approval required. Anything that requires approval will now require either your password entered on the child's device or approval from your device. You can prevent your child from downloading adult games or songs with explicit lyrics using Google Play's parental controls. To do so, launch Google Play on your child's smartphone, open up the menu, and tap on Settings Parental Controls. Enter a PIN - something easy for you to remember but hard for your child to guess. The requirement to enter a PIN prevents your child from disabling the controls. After entering the PIN, you can select age restrictions for games, films, and music separately. To prevent unsupervised Internet use - and gain better control over mobile data usage - start by disabling mobile data use both in the settings of your child's smartphone and using your mobile service provider's self-service options. After that, use the smartphone's settings to join your home Wi-Fi network. Now it's up to you to monitor that use inside the home, of course. Disabling mobile data should help keep the child online only at home. True, free Wi-Fi can be had in a library or at a friend's home, but I will address that later in the post. By the way, when buying a SIM card for your child, ask the carrier about special plans and options for children - these plans and options usually include additional features for keeping children safe. Sure, the games installed on your child's smartphone are intended for children, but still, stay alert. Children can spend endless time mine crafting and launching angry birds. Limiting gaming duration with Android's built-in tools is problematic; therefore, look to dedicated apps such as Kaspersky Safe Kids. The Safe Kids app's many features include location and social-network controls, but here we are interested mainly in defining restrictions on launching apps and making the Internet safe to use. To use it, install Safe Kids on both a parent's and the child's smartphones. Set the modes, child mode for the child's smartphone and parent mode for yours. The child's app has almost no settings for you to worry about - just install the app according to the instructions and grant it administrator rights. You will have a bit more to do for the app on your own smartphone - you will need to set up a PIN for Safe Kids, check its settings, and enable options. The crucial ones are the ability to filter unwanted websites and app restriction by category and age, which are located on the Internet and Applications subsections respectively. Now, let's restrict the amount of time the child can spend at the display. You can allot, for example, 15 minutes, 1 hour, 2 hours, or more. After that, the smartphone will be able to make and receive calls, but most of the other apps will be blocked with a notification that time is up. If your child does not tend to spend too much time on pictures and SMS messages, then we can take the opposite tack and assign an amount of time allowed in specific apps, such as games. At the same time, we can completely block access to some apps, such as any browser other than Google Chrome and Android's built-in browser (which are protected by Safe Kids' content filter; other browsers may have access to unwanted websites). Safe Kids provides comprehensive parental control, including protection against its own deletion, and the recent update has brought one more useful feature - restricting access to smartphone's own settings. It's worth doing to make sure your child will not be able to connect to unknown Wi-Fi networks, reset the system time, or mess with settings in some other way you did not predict. I personally used to recommend an app called Smart Applock for that purpose, but now that Safe Kids has this feature I suggest using it and not installing additional software to execute this task. One last setting: the lock screen. Enable a lock screen to protect the smartphone from classmates and others who might find it. You can do that through Settings Security or Settings Lock screen. Work with your child to ensure he or she is comfortable entering the PIN or pattern that unlocks the phone. Software and settings are not a substitute for ongoing parental guidance. Get involved with your child's smartphone usage. Talk about surfing, gaming restrictions, and all that, but expect that your child will find ways around your "smartphone usage plan" - and adapt as needed.1. smartphone or phablet?What exactly is a phablet?2.

Why Is the Purchase of Smart Door Locks so Small
Why Is the Purchase of Smart Door Locks so Small
Since 2015, the smart door lock industry has entered a period of rapid growth, with a significant increase in annual shipments. Especially in 2018, the shipment volume in the first half of the previous year has exceeded the annual shipment volume in 2017. In view of this growth rate, some market institutions predict that the annual shipment will exceed 22 million in 2018 and 30 million sets in 2019.Such a "wonderful" number is really like a dose of "heart booster" to stimulate the market confidence of the majority of door lock enterprises. At the same time, it also makes many entrepreneurs see a new 100 billion market. As a result, a large number of door lock enterprises have been established and many brands stand in the city.If it grows at this rate, it is indeed expected to reach the 100 million mark in a few years. There are more than 600 million families in China, and the penetration rate of smart door lock in the home end is only 3%, while that in Europe and the United States is more than 40%, and that in Japan and South Korea is about 70%. However, the vision of the market was severely "beaten in the face" by the reality.In 2018, the actual shipment of smart door locks nationwide was about 12 million sets, which is far from the predicted figure. What about 2019? The author learned from people in the industry that the shipment volume in the first half of 2019 was about 6 million units, which decreased slightly compared with last year. It is expected that the annual shipment volume will also remain at the level of 2018, about 12-13 million units.It is reasonable to say that the application of intelligent products has been gradually accepted by consumers, and the "body" and "money" in the "skill key money" have been gradually far away from our belongings, so it should be acceptable to use intelligent door locks without carrying keys.However, the purchase of smart door locks is still small. The author believes that there are mainly the following reasons.Consumers lack confidence in product safetyDoor lock is the first defense of family safety. Its function is to ensure safety and prevent illegal intrusion. Therefore, the safety of intelligent door lock is not only its core value, but also the most concerned factor for consumers to buy products. However, the security problems of intelligent door lock are frequently exposed and frequently reported. The State Administration of market supervision and administration, CCTV and consumer associations all revealed the safety problems of smart door locks through the media, and the sampling test results are worrying. There are security vulnerabilities in the mainstream fingerprint, password, IC card and remote unlocking functions.1. Security problems of fingerprint unlocking functionFingerprint unlocking of intelligent door lock is divided into optical fingerprint identification and semiconductor fingerprint identification. Optical fingerprint refers to fingerprint acquisition and authentication through the surface texture of light reflection fingerprint, which has certain obstacles to false fingerprint identification. Therefore, the security level of optical fingerprint identification is relatively low.Semiconductor fingerprint head can identify and authenticate fingerprints through technologies such as temperature, capacitance value and inductance value, which can more effectively prevent the risk of "false fingerprints" such as fingerprint film and fingerprint sleeve, and the security level is relatively high.However, at present, the fingerprint identification modules used by most intelligent door locks are the overall scheme provided by fingerprint module manufacturers, including the encryption verification mechanism for fingerprint reading, storage and identification. Whether the key strength in this encryption mechanism can resist attack is unknown. Especially for networked locks, when cloud verification is required, the transmission encryption of fingerprint verification instructions is particularly important. Whether it can prevent network attacks and information leakage is an important security issue to be considered.2. Security problems of IC card unlocking functionThe security problem of IC card unlocking is more prominent. According to the test results of the Consumer Association, more than 85% of the samples are unqualified. According to the author, at present, more than 95% of the unlocking IC cards used in smart door locks are M1 cards. The card algorithm was cracked as early as 2009, and there is a M1 card cracking program on a treasure.No matter whether the smart door lock manufacturer adds a key to the M1 card or not, the key can be read out and copied through the cracking program. Once the key is read out, the key can be cracked exhaustively, which will lead to the complete breach of the key of the intelligent door lock enterprise, resulting in a huge security risk of the sold products. Therefore, the security risk of IC card unlocking comes from M1 card.In addition, some smart door locks can be unlocked by binding bus cards, bank cards and ID cards. The security risk of this function is greater, because this unlocking method does not even have a card verification key. It is only authenticated and unlocked through the chip uid number or serial number, without any security protection, which is a great risk.3. Remote unlockRemote unlocking is to control the door lock through the mobile phone app to achieve the purpose of authentication unlocking. At present, there are Bluetooth, ZigBee, WiFi, Nb, Lora and other connection methods, but no matter which way, it needs to connect and interact with the intelligent door lock control cloud platform, so there are network attacks and command interception in the process of information transmission. Whether the instruction transmission has encryption protection and whether the cloud platform has anti attack capability are related to the overall security of the product."Infighting" intensifies and it is difficult to form a brand effectAt present, there are more than 2000 domestic intelligent door lock enterprises and about 3000 brands. Most of them belong to the scale of "small workshops" and impact the market at low prices, making the original healthy market "scattered". Some door lock enterprises have no choice but to reduce prices and participate in the price fight. How is the current smart door lock market like the mobile phone market a few years ago? Low price door locks are everywhere, and when will the price fight end.Intelligent door lock is a product integrating traditional hardware and intelligent control. It requires not only familiarity with traditional hardware, but also research and development of product design, electronic control, information security and network transmission. More importantly, it is necessary to establish production line, sales channel and after-sales service system, which requires huge capital investment for enterprises.Low profit margin product sales lead many enterprises to reduce investment in product design, R & D and iteration, and tilt limited funds to sales (especially door lock enterprises focusing on offline sales). Is this strategy right or wrong? The author believes that under such market competition, the strategic adjustment of enterprises is also helpless. After all, the survival of enterprises is the first.When I communicate with people in the industry, I often hear enterprises complain about the impact of low-cost products on the market, but I am very helpless. I also hope that the market can eliminate some "three noes" enterprises. However, there will be low-cost competition at any time, and it is difficult to achieve the purpose of survival of the fittest only through market "reshuffle".Product homogeneity, lack of "bright" productsThe core of intelligent door lock is security, taking into account the greatest attribute of convenience and intelligence. The current intelligent door locks are innovated in the unlocking mode, so they are seriously homogeneous, easy to imitate and easy to produce. However, in view of the investment in R & D costs, almost all manufacturers follow the superposition of security functions, so it is difficult to produce "hot" products that make consumers excited and have a strong desire to buy.The homogenization of product design is serious, and the product has not really entered the hearts of consumersUser habits have not been really developed. At present, most domestic users are still used to using key lock. In particular, the middle-aged and elderly people have deep traditional ideas. First, they lack interest in new things, and second, they lack consumption motivation, which makes people feel that it is not necessary to spend "wronged money".IResearch has released relevant data. Nearly 65% of respondents said that when it is necessary to replace the anti-theft door or lock, they will consider the smart door lock, but they will not change the lock simply because of changing the lock. At the same time, the frequent security problems of intelligent door lock are also an important reason why users can't go up.In view of the above reasons, the author puts forward some ideas for readers:1. Improve product qualityQuality is the "King" of products. Involving product safety, stability and durability. In terms of safety, the overall safety of the product shall be improved under the existing technical conditions. The most important thing is that the IC card should be replaced with CPU card. The fingerprint verification, remote transmission and password verification should be added with the key for encryption verification and secure transmission, so as to improve the overall anti attack ability of the product.2. Innovative product performanceSmart door locks must be Internet of things products in the future. Research should be carried out from the perspective of Internet of things smart home products in the next 2-3 years to innovate the new functional value of smart door locks in addition to unlocking. In this way, inevitable technical barriers are formed to achieve the purpose of core competitiveness.3. Improve reputation and establish brand effectThe negative report of smart door lock has dragged down consumers' purchase confidence. The smart door lock industry needs several "leading brothers" to carry the banner, stabilize the market and revitalize the reputation of industry products. At the same time, verify the product quality through self inspection and external inspection, and establish a list of industry brands.4. Scene ecologyIntelligent door locks tend to be ecological. In the field of smart home, the era of "single product is the king" has ended. Especially under 5g, smart home products that cannot be integrated into ecology are not good products. Therefore, it is obvious that the intelligent door lock also needs to be ecologically linked with the whole intelligent system in order to have more tenacious vitality.For example, integrated into the smart community application system, the "smooth opening" of community access control, unit access control and home door lock can be realized through one key or one card of mobile phone. At the same time, the application in the field of urban public services can be opened horizontally. Taking public transport tools with smart door lock card (physical card or mobile phone card) is no longer a dream.Once the ecological scenario is formed, the directional selection of intelligent door lock products will open the competitive gap with similar products.
