Bluetooth

Bluetooth is a wireless Bluetooth technology design based on research and development of vehicle wireless hands-free system. Main function in normal driving with Bluetooth technology and mobile phone connections for hands-free calls, has reached the liberation of hands, reduce traffic accident hidden trouble to.

Concept

Bluetooth system of Bluetooth technology is from mobile phone Bluetooth technology continued, with the same launch system.

Car Bluetooth function is the automatic identification and mobile phone, without the need for cable or telephone bracket can mobile phone online; the owner can not contact mobile phone, even the hands stay on the steering wheel, can control the mobile phone, with a voice command control answer or dial the telephone. The user can through the car stereo.

Ethernet electronics to publicize its Bluetooth technology even launched a sophisticated with solar charger hands-free Bluetooth -- black king kong. Black King Kong use of rechargeable lithium battery, and equipped with a special solar charger. The driver can answer the call without having to wear headphones and can use the new denoising technique to reduce the disturbance of other sounds, showing strong science and technology charm.

If the Bluetooth technology and the whole car audio support, when in use, a Bluetooth-enabled mobile phone and car stereo mix together, convenience for drivers in calls when, can automatically switch stereo sound, mute, hang up the phone when voice automatic recovery.

Installation of Bluetooth system, the drive when answering the phone without distraction. To answer the incoming call, users only need to gently press a key or by voice control can answer the call, so improve the driving safety and convenience.

At present the majority of Bluetooth system to support the conference call, MP3 player and other functions, simple operation, can be simultaneously connected to a plurality of telephones, thereby greatly improving the driving safety.

Rich Internet Applications (RIA)

Rich Internet Applications ( RIA ) with very strong interactivity of rich client technology to provide users with a higher and more comprehensive network experience.

RCP ( Rich Client Platform ) provides a common Eclipse platform, allows developers to extend and build your own application.

Brief introduction

Rich Internet Applications ( Rich Internet Applications, RIA ) with very strong interactive rich client technology to provide users with a higher and more comprehensive network experience. RIA integrated desktop application of interactive and traditional Web application deployment flexibility and cost analysis, in order to create a single, complete user experience. Rich client technology enables the creation of RIA possible, it provide a run-time environment for bearing is compiled by the client application, the client application is an agreement to use HTTP released documents. The client application using asynchronous C / S structure attached to the existing application server, which is a secure, scalable, and has good adaptability of service oriented model, this model consists of the current used by the Web service drive.

Rich client technology is constantly improving, but it does not mean that will replace HTML. On the contrary it will further expand the capabilities of the browser, to provide more efficient and friendly user interface. Many RIA are run in the browser, even it is part of the HTML, so HTML will continue to maintain its original role. In addition, due to the rich client technology can support the motion image, video, audio, bidirectional data communication and create complex forms, it is to create the application user interface provides an efficient and complete development environment.

RIA development must have three elements: the rich client technology, server technology and development tools. Rich client technology makes full use of the local machine processing capacity to process data, but do not need to be certain that send data to the server process, make full use of the local machine resources. Server technology provides a rich client connection mechanism, as the RIA server technology must be from an existing server technical inheritance, can provide a quick scripting environment, support the development and application of database, data communication, data communication, even using a new server, for example: ColdFusion Server and Flash Communication Server and so on. RIA must have a set of simple and effective development tool, if not a set of simple and effective development tool, then the rich client technology and server technology is meaningless. It is because the RIA C / S structure, it needs a set of development tools work together to complete.

Although there are many rich client technology, but Macromedia Flash Player has been widely used, it has gradually become a rich client technology network standard. Flash Player is a ubiquitous media client, it can be in a different browser and operating system is running, so it is a cross-platform, operating system network client.

" The rich" concept includes two aspects, which means it has a rich user interface and abundant data model.

The typical rich client model

Rich client model interface is decomposed into many can directly with the user interaction and the server can communicate and small unit module.

The application of design from a relatively independent of the page as the center shifted to the assembly as the center of the change will allow customers the design to a new level, and make customers become more flexible. Rich client layer will no longer be a server in response to the terminal, which also makes the program performance can be enhanced, the user feels as if procedures are not required and the server or only occasionally need to communicate.

Unlike the traditional model, the server receives the request from top to bottom. After creating the client interface, you don't have to predict the sequence of events. Since each component are independent, there is no need for a request to affect the whole view of the reaction. To make each component has the information transmitted to the server capacity needs of each form know how to handle server transmits information back. In RIA, client and server interaction data are not synchronized, so you can control components to create information sent to the server and the server response, can provide more scattered control decoupling and separation procedure function and the formation of service oriented program structure.

Rich Client is a relative concept, is mainly directed against the widespread application based on the WEB, because the client ( i.e. the various existing browser ) running environment does not provide a very good component model and interactive model that the application interface with service between the interaction becomes very strange, each interaction between both need to organize the entire interface, and that interface organization completed at the server, and therefore cause the presentation layer logical in the server, so called the Thin Client, while the relative is Rich Client, currently in the technology on Rich Client is not an even two unification and maturity and standard techniques, so Rich Client can say is a kind of Architecture, its characteristic is the service with the performance of the complete physical separation, presentation logic completely by the client to be responsible, and this is the key point. But I think it must be at the same time and Gu Yuan WEB application deployment characteristics such as zero.

C / S architecture, the client program release and maintenance has been more difficult and tedious. In the updated version, the need for customer client program carried out by downloading and installing and configuring and updating, which is a manual work, and it also has a large selection of WEB is to make the user program is one of the factors.

In the Rich Client era, the broadband network convenience, in the client do need from the server downloads have been updated program run, regardless of trival download, installation and configuration process. Here have to mention Java's WebStart technology.

WebStart

WebStart is to let the user only in the webpage clicking on a hyperlink will be able to run on a Java desktop application technology. For a WebStart has a capacity of Java applications, users use it and using the WEB application as a simple, but it has the interface capacity and local processing ability is WEB application cannot approach somebody's greatness.

Chest like most of the 4 kinds of food

1 Green Papaya

Green papaya has always been the first breast good fruit, papaya is rich in papaya enzyme on mammary development is very helpful, and papaya is rich in breast enhancement hormone and vitamin A nutrients, can stimulate the secretion of female hormones, and can stimulate the secretion of ovarian estrogen, breast unimpeded, so as to achieve the aim of breast.

2 corn

Fresh corn contains rich vitamin E, it can regulate the body's nerve and exudation, enhanced the new supersedes the old. Function, and can make to the subcutaneous tissue and resilient, if often supplement of vitamin E, the skin will be full of elasticity and luster of female. Corn also contains vitamin B6, niacin and other ingredients, is to stimulate peristalsis, accelerated drying is the excretion of characteristics, can help us to prevent constipation, colitis, colon cancer. Corn with glial be roughly the same compared to breast enhancement effect. It is rich in calcium, phosphorus, magnesium, iron, selenium and vitamin A, B1, B2, B6, E and carotene rich nutrition, can help develop the chest, also slimming effect!

3 fungi

Of Hericium erinaceus: containing polysaccharides, polypeptides, against cancer cells have a stronger inhibitory effect, and can produce interferon, elevated white blood cell, enhance the immune function of human body, plays the role of preventing and curing cancer.

The mushroom: nutrient-rich, containing the human body essential amino acids, vitamins and minerals, including selenium rich vitamin D, can enhance human immunity, is conducive to the prevention of gastric cancer and esophageal cancer.

4 dates

The medical profession early studies confirmed, jujube warm sweet, containing protein, a variety of amino acid, carotene, vitamins, iron, calcium, phosphorus and so on, not only can promote the secretion of female hormones, strengthen breast development, and replenishing spleen, conciliate resistance, nourishing the blood divine. So many women like to drink red dates tea or red jujube milk, can beauty blood and breast.

Wall motion promote digestion and lowering blood pressure

Experts believe that the human body kinematics, the back spine and spinal nerves on both sides of the distribution of wealth and many important points, and limbs, organs have extensive contacts. The back wall is not only can regulate visceral, relax the muscles, gas line through orifices, peace of mind rather God, spleen, stomach, and can also be wet, to assist in the treatment of cervical disease and cervical spondylosis. Insist for a long time can not only promote the local and systemic blood circulation, strengthen the endocrine and gastrointestinal function, improve the immunity of the human body, can also lower blood pressure, treatment of insomnia.

However, the back wall of fitness should be gradual, the initial impact will be ready in 5 minutes, gradually extend the time, one should not exceed 30 minutes. Hit the back of fever and comfortable, can, can't hit too hard. Suffering from heart disease, visceral ptosis, high blood pressure, such as advanced cancer patients, it is not suitable for wall body.

Fiber-to-the-x ( FTTx )

Fiber-to-the-x ( FTTx )

( FTTx, x = H for home, P for premises, C for curb and N for node or neighborhood ) where FTTH FTTH fiber to the resident, FTTP, FTTC fiber to the curb / community, FTTN fiber to the node.

Fiber to the home ( FTTH ) is a 20 years people have been pursuing the dream and the exploration of technical direction, but due to cost, technology, demand and other aspects of the barrier, so far has not been large-scale promotion and development. However, the slow progress of the situation recently has changed a lot. As a result of policy support and the development of technical itself, in after years of silence, FTTH once again become a hot spot, has entered a rapid development period. The rise of various related broadband applications such as VoIP, Online-game, E-learning, and intelligent home and brings to life the comfort and convenience, the HDTV created interactive high definition TV revolution which has high bandwidth, large capacity, low loss and other excellent properties of the fiber to transmit data to the client becomes the inevitable choice of the medium. Because of this, many a person with breadth of vision to FTTx ( especially fiber to the home, fiber to the resident ) as optical communication market recovery important turning point. And is expected in the next few years, FTTH network will have greater development. This article will be on the FTTx division, the main technology and FTTx now in development around the world and make a comprehensive introduction.
