A big step towards true interoperability

The AllSeen Alliance, formed by the Linux Foundation, is a non-profit organization dedicated to the widespread adoption of connectivity products based on the open, universal development framework of the AllJoyn open source project.

This is a major event. We believe that the main obstacle to the full realization of the Internet of Everything is the lack of a unified framework that can always prioritize intelligent interoperability between different systems under any transport layer, platform, operating system or brand. The current "solutions" for connecting terminals are usually proprietary, creating isolated terminals and systems that are powerful but not interoperable.

Qualcomm InnovaTIon Center, Inc., an open source subsidiary of Qualcomm, launched the AllJoyn open source project in 2009 to address this pressing issue. AllJoyn is built on a self-describing-based terminal to dynamically learn which terminals are nearby and which features or interfaces they want to interact with. This concept of "introspection" brings what we call an ad hoc network. We think it is extremely important if you want your connection terminals to be backward compatible.

Some of our partners have been focused on implementing use cases that interact with one or two specific terminals. However, because all of these systems use AllJoyn technology, we are always excited about these novel experiences. Imagine... a security system that was originally designed to ensure that different sensors can trigger an IP camera and alert your smartphone, suddenly expanding its capabilities and uses when it found AllJoyn's TVs and light bulbs in the vicinity. With AllJoyn, these disparate systems automatically discover, communicate and interact to bring a new experience. Now, they can not only send reminders to your mobile phone, but also pop up messages on the TV, while the home lights will flash in different colors to scare off uninvited guests.

Terminal vendors are excited about this because with AllJoyn, they produce products that not only interact with other terminals, but also increase their interaction capabilities when purchased by end users. We believe that this will be a big competitive advantage when consumers learn to find and start to prefer terminals that can easily fit into AllJoyn's neighboring networks. Consumers are looking for these products because they know that the terminals they buy today can work with future-purchased terminals, and their capabilities are enhanced through this interoperability.

Qualcomm has recognized that a project with such ambitious goals that many brands and types of terminals can easily interact needs to be managed by a group of like-minded companies that benefit from AllJoyn's Widely popularized and expanded. The AllSeen Alliance is such a group - just look at the original members and you will know. Through this alliance, AllJoyn will continue to grow and develop with the help of various corporate and technology leaders around the world. We are excited because we know that open source software and pan-industry collaboration can quickly drive technology growth, promote innovation and encourage the market.

With AllJoyn and its service framework to ensure interoperability and the AllSeen Alliance, the Internet of Everything is just around the corner. We are pleased to see that with the help of the Alliance, our partners will launch a series of innovative terminals in 2014. Qualcomm strongly supports the collaboration of all members of the AllSeen Alliance and will continue to make substantial contributions to AllJoyn and its service framework. 2014 will be the most exciting year, as AllJoyn will break through the smart phone and peer-to-peer applications to enter your smart home. What kind of killer experience would you use with AllJoyn?

Take a deep breath, close your eyes, the world has the freshest oxygen ... Yu Quan's "Deep Breath" is well known to us, but as the environmental problems become more and more serious, the haze sky also increases, PM2.5 PM10 and so on Vocabulary has also been mentioned more and more, and air purifiers have quickly become popular on the market with this "air quality" trend. Along with this, the air-clean brand has sprung up, and various technologies are dazzling. Which ones are indeed effective and which are just tasteless propaganda? How does the Air Purifier bother us to get rid of pollution? And look at the editors for you.

Analysis of air purifier

The critical value of PM2.5 content is 75 μg / m3

The pollutants in the air mainly include soot, total suspended particulates, inhalable particulates (PM2.5) and fine particulates (PM10). The smaller the diameter of the particulates, the deeper the part that can enter the respiratory tract. 10 micron diameter particles It is deposited in the upper respiratory tract, and particles below 2 microns can penetrate 100% into the bronchiole and alveoli.

1k-5k air purifier prices vary greatly

The air purifier products on the market not only have various functions, but also have prices ranging from thousand yuan to tens of thousands. The pricing of imported products is generally higher than that of domestic brands. Except for the core technology of many brands, the promotion of purification effects is similar, and consumers need to choose according to demand.

The air quality standard of 74 key cities is only 4.1%

According to the data of the press conference held by the State Council Information Office on June 4, according to the new "Ambient Air Quality Standards", the six pollutants SO2, NO2, PM10, PM2.5, CO and O3 were evaluated, 74 new standards In the first phase of monitoring and implementation, the proportion of cities that met the ambient air quality standards was only 4.1%, and the other 256 cities implemented the old air quality standards, and the proportion of cities that met the standards was 69.5%.

Air purifier sales increased by 90.5% compared with last year

According to a report recently released by the China Electronics and Information Industry Development Institute, due to the haze weather, air purifiers have become the most concerned home appliance products, with sales of nearly 2.4 million units nationwide last year, a year-on-year increase of 90.5%; retail The amount reached 5.6 billion yuan, a year-on-year increase of 105.9%.

HEPA filter needs to be replaced in March

The filter of the air purifier is the same as the filter of the water purifier, and it is not effective for a long time. After long-term use, the accumulation of dust on the surface of the filter will also cause the filter to gradually fail. Therefore, when the haze is more serious, the non-washable HEPA filter needs to be replaced every three months.

Merchants claim that the purification rate is more than 99% for the concept of stealing

99% or even 99.99% seems to have become a slogan for many air purifiers on the market. Many brands of products promote their high removal rate of PM2.5 and formaldehyde. In fact, this kind of publicity is more of a kind. The slogan of stealing the concept, the removal rate of 99% is the effect of the material itself on PM2.5 and formaldehyde, not the effect of actually running in space.
