"simple and reliable" principle, do not like to use complex webserver. Industrial equipment also does not like the LCD screen, LCD display reliability is low, reducing the overall reliability of the equipment, LCD monitor open such a large window, directly increase the cost of EMC and EMI equipment.2. Industrial equipment may also be installed in areas of personal danger that cannot be approached by people and, of course, cannot be viewed. Industrial Smart hardware requirements manufacturers to
is used in usb flash drives, various memory cards, and MP3 players. due to technological differences, nand flash has a larger storage capacity than nor flash, and cheap. However, there are also disadvantages: you cannot directly run programs with addressing, and you can only store data. In addition, nand flash is prone to bad areas, so verification algorithms are required.
In the handheld computer, you must use nand flash to store data and programs,
in this field.In addition, in terms of software development. Microsoft released 18 new Windows CE 3.0 board support software packages (BSP), further reducing the time required for OEM products to be put on the market. To fully occupy the embedded system market, Microsoft will provide various solutions to embedded system developers. These solutions include infrastructure technologies, such as COM (Component Object Model) and Windows Media technology, embedded operating systems and toolkit, and a

security can rely on the WLAN itself with the security measures provided, but also need to rely on a number of special security products to achieve, at the same time need a reasonable set of WLAN special security management norms and systems. Here are some security products that you can use for WLANs.
The WLAN security products of the Crown group Golden Chen Company
Golden Chen Company is a professional information security program and service providers, to provide firewalls, intrusion detect
collection process management is to control the time advances, effectively handle various events in the process, quickly respond to customer requirements, and meet customer satisfaction requirements. Reasonable and effective scheduling is very important for the management of distribution and collection processes.The information system of modern logistics management is generally called the logistic Execution System les to complete the logistics automation process. It consists of three parts. The
At present, mobile computing and communication devices are popular mostly because they have some convenient functions. For example, they can send information to other users as needed, you can use your handheld devices to access and execute applications anytime, anywhere, and even obtain and update information during flight.

8. Use personal firewalls and anti-virus software on the WLAN client to prevent damage to client attacks.
As mentioned above, the security of WLAN can be provided by the security measures of WLAN itself, but also by using some dedicated security products, at the same time, a set of reasonable WLAN dedicated security management specifications and systems are required. The following describes some security products that can be used for WLAN.
After analyzing the security of Wireless LAN, we
For the application of the HART protocol, we will introduce the hand-held HART communicator. What are the characteristics of the application of this product? Let's introduce it to you. Through the picture, we can see the appearance of this product, then the model of this product is ESC-375H. It features: The HART375C handheld device is a handheld device that provides a public communication interface for All
, such as classifying and combining complex data passed by the front end, and the DAO layer encapsulates the most primitive operations on the database. Connecting the underlying database increases data support for the first two tiers. In order to stabilize the system, there are related packages are manually added and then by setting the path path into the project, where the SRC directory of the configuration file is mainly for the processing of things and Struts2 files, Lib jar package is three
. In a more popular way, mobile phone users can enjoy Internet services, such as news, e-mail and ticketing, e-commerce and other professional services.WAP supports most wireless networks, including GSM,CDMA,CDPD and so on, while all operating systems support WAP, which is specifically designed for handheld devices with Palmos,epoc,windows Ce,flexos. OS/9, and Javaos.WAP is a technology that enables the introduction of a wide range of Internet informa
appliances has also contributed to the development of embedded software. Color TV, DCD, mobile phones, MP3/MP4, handheld computers, and automobiles are all potential information appliances. Unlike general operating systems and databases, the information and electric appliance platform does not have a monopoly on the market of foreign software vendors. This field has become a breakthrough in China's software industry.Embedded systems are designed for
By defining style sheet rules with different media types and conditions, media queries allow CSS to work more precisely on different media types and different conditions for the same media. Most media features of media queries accept Min and Max to express "greater than or equal to" and "small and or equal". Such as: Width will have min-width and max-width media queries can be used in CSS @media and @import rules, can also be used in HTML and XML. With this tag property, we can easily achieve a

When the fragment you add is part of the activity layout, it resides in a ViewGroup of the activity's view structure, and fragment defines its own layout. You can define fragment in the activity layout file to insert it into your activity, like
Or add it to an existing ViewGroup through the code in your application. However, a fragment does not have to be part of the activity layout. You can a
Bitmap for a handheld device that uses gray display, you can use MS paint to select white, black, light gray, and dark gray entries from the palette (typically the first two colors of the first and second rows) to build a bitmap. Save it as a 16-color image, and then use 2bit tool to convert it into a two-bit bitmap.
