Online now there are three views, one is based on the browser sent User-agent, but obviously this method is not feasible, although some people list the most mobile phone sent user-agent, but there will still be a lot of mobile phones are not recognized, and even some mobile browsers do not send User-agent, And there is no guarantee that a new brand will be in the future. Here's an example of PHP, and you'll see how unreliable it is. 1. function Is_wap () { 2. $ua = Strtolower ($_server[' http_u

cycle from the standard 12 system cycles, and the peak performance will reach 25 MIPS. In addition, the CAN controller and high-speed A/D converter can be integrated in the to simplify the system design. The CAN controller is integrated with the. To run the CAN bus, the can transceiver must be connected to the single-chip microcomputer to perform electrical conversion and convert the logic signal into a balanced Differential Code. Commonly used can transceiver is the pca82c250 and high-speed TJ

The SAA7111A of Philips is used as the video A/D decoding chip. It converts the analog video signal output by the CCD camera into digital image data and stores it in RAM under the control of FPGA, at the same time, line synchronous signals (HS), field synchronous signals (VS), parity field signs (RTS0)

addition, it can connect to 254 nodes. Nodes can include instruments and automated home application devices. Its own characteristics make it very promising in industrial monitoring, sensor networks, Home monitoring, security systems, and other fields. The main performance comparison of several common wireless transmission modes is shown in table 1. 2. the technical content and features of ZigBee are the latest commercial names. In the past, the initiators named "HomeRF lite", "Firefly", and "R

, this greatly improves the detection speed of the entire detection system. FPGA plays a very important role in the system. Some data signal processing is done through it. Its internal function Diagram 6 shows. It can be seen that FPGA is mainly composed of Narrow Pulse Generation sampling delay module, parameter register module, data collection compression module, dual-port RAM module, and automatic defect judgment module. For detailed working principles, see [3]. 7. Microprocessor and USB Int

1 I2C communication protocol and S3C2410 chip Introduction I2C (Inter Integrated Circuit) bus was launched by Philips in 1980. The I2C bus transmits information between the bus and the device using two wires (SDA and SCL), serial communication between the microcontroller and external devices, or bidirectional data transmission between the master device and the slave device. The two communication lines are pulled up to + 5 V through the pull-up resisto

technological development, and manufacturers also recognize this bottleneck. At this time, COMPAQ, Hewlett Packard, Intel, Lucent, Microsoft, NEC, and PHILIPS jointly developed the USB 2.0 interface standard. USB 2.0 increases the data transmission speed between devices to 480 Mbps, about 40 times faster than the USB 1.1 Standard, the biggest benefit of speed improvement for users is that users can use more efficient external devices, and peripheral

? Answer NFC, developed jointly by Philips and Sony, is a non-contact identification and interconnection technology that enables close-range wireless communication between mobile devices, consumer electronics, PCs, and smart control tools. NFC provides a simple, touch-based solution that allows consumers to easily and intuitively exchange information, access content and services.The above is Baidu's explanation of NFC. Today we are going to talk about

playability is reduced. If the ophone can double the standby time, the number of users will be greatly increased. Philips is doing very well. Although the function is very simple, even the interface is simple, but because of the excellent battery technology, there are still a large number of users. I think if the ophone uses a fuel cell to prolong the standby time, it will be very fit for the user's needs. Secondly, due to the closed windows mobile

Nowadays, mobile phones are becoming more and more popular, and more functions are available on mobile phones. Many people begin to develop applications on mobile phones, but mobile platforms are varied. Program With high commercial value, we must be able to adapt to a majority of mobile phone platforms. to fully consider the portability of programs, I have been in touch with mobile phone application development for nearly three years, I have developed many mobile phone platforms, such as the s

sound quality is the best, while the low-complexity specification (LC) is relatively simple, without gain control, the encoding efficiency is improved. The SSR and LC specifications are roughly the same, but the gain control function is added. In addition, LTP/LD/He are all used for encoding at Low Bit Rate. He adopts the neroacc encoding tool, which is a common encoding rate method recently. However, the main specification and LC specification have little difference in sound quality. Therefore
