摘要： A technology for detecting an RFID by a reader writer and transmitting harmonics for reading and writing the RFID timely without using an object detection sensor is provided. Using a nonlinearity of a rectifier or a demodulator in an IC chip of the RFID, a continuous wave or a modulated wave of two or more different frequencies is output from the reader writer. The RFID receives the continuous wave or the modulated wave of two or more different frequencies and the reader writer receives harmonics intermodulation generated by the rectifier or the demodulator in the IC chip. Therefore, the RFID can be detected without any special object detection sensor, and a modulated wave for reading or writing the RFID can be transmitted.

摘要： A technique of reducing the interference wave occurred between a plurality of reader/writers in an environment in which a plurality of RFID systems are operating. An RFID system includes a plurality of reader/writers and a controller for controlling the plurality of reader/writers. Each reader/writer includes a body, antennas, and a distributor for selecting one antenna from the antennas. The controller selects an antenna having a positional relationship in which the interference wave is small from the antennas of each reader/writer, and giving a command for the antenna to the body of each reader/writer. Each reader/writer selects one antenna from the antennas based on the command from the controller and transmits a command to the RFID.

摘要： A reader/writer (R/W) transmits a query command ALL (A), which causes RFID tags (A) with a communication method (A) to respond at a time, to N RFID tags (A) with the communication method (A) and X RFID tags (C) with a communication method (C). In this case, since R/W receives responses from N RFID tags (A), it can recognize presence of the RFID tags with a communication method (A) from its reception level or the like. Next, R/W transmits a query command ALL (B) which causes RFID tags (B) with a communication method (B) to respond at a time. In this case, since R/W receives no response, it can recognize that no RFID tag with the communication method (B) is present rapidly. In an RFID system, therefore, a communication time between RFID tags and an RFID reader/writer can be reduced.
摘要翻译：读取器/写入器（R / W）通过通信方法（N）向N个RFID标签（A）发送一个使得通信方法（A）的RFID标签（A）一次响应的查询命令ALL（A） A）和X RFID标签（C），具有通信方法（C）。在这种情况下，由于R / W接收到来自N个RFID标签（A）的响应，因此可以从其接收等级等利用通信方法（A）来识别RFID标签的存在。接下来，R / W以通信方式（B）发送使得RFID标签（B）一次响应的查询命令ALL（B）。在这种情况下，由于R / W没有收到响应，因此可以认识到没有快速存在具有通信方式（B）的RFID标签。因此，在RFID系统中，可以减少RFID标签与RFID读写器之间的通信时间。

摘要： In order to provide a highly secure system at a low cost without providing a complicated logic circuit for an RFID tag, in a system including an RFID tag (10) and a interrogator (20), the interrogator (10) is provided with a password creating unit (1100) which computes an electronic key (131) and a keyword unique to the RFID tag with a predetermined irreversible function to create a password. By using the password as a key, item information of an item attached with the RFID tag (20) is encrypted with a predetermined encryption function. The encrypted item information and the keyword are written to the RFID tag (20). The interrogator (10) reads the encrypted item information and the keyword from the RFID tag (20), causes the password creating unit (1100) to compute the password by using the keyword, and uses the password as a key to decrypt the read encrypted item information.

摘要： A graphics system which accelerates generation of pixels including transparent objects by simply adding more rendering devices. The system has composition means and a plurality of rendering devices each comprising a geometric processor, a rendering processor and a frame memory that holds color, depth and weight data in a screen bit map format. Given a plurality of sets of color, depth and weight data about any one pixel position from the frame memories, the composition means first compares the depth data, and multiplies successively the weight and color data starting with those corresponding to the depth data closest to the foreground, thereby generating new pixel data. The system thus permits merging of transparent objects.

摘要： A distributed drawing processing system which includes a drawing server for integratedly executing a string of drawing commands transmitted from a client program for graphics display. In the system, the client program divides the drawing command string into a drawing command block of a string of drawing commands processable on a parallel basis and a drawing command block of a string of drawing commands not processable on the parallel basis, and transmits the divided drawing command string blocks to the drawing server. The drawing server executes the drawing command string while judging whether to process it on the parallel or sequential basis with respect to each of the divided drawing command string blocks.
