| 20090258592 | Radio Frequency Identification Tag and Operating Method Thereof - The invention provides a radio frequency identification (RFID) tag. The RFID tag includes a receiving module, a judging module, and a jamming module. The judging module includes a first judging unit and a second judging unit. When a jamming function of the RFID tag is activated, the first judging unit judges whether a request signal received by the receiving module contains a reading command. If a judgment result of the judging module is positive, the second judging unit then judges whether an authorization code of the reading command is valid. If either the judgment result of the first judging unit or the second judging unit is negative, the judging module controls the jamming module to generate a radio frequency (RF) jamming signal. | 10-15-2009 |
| 20090278667 | Method and Computer Program Product for Loading and Executing Program Code at Micro-processor - A method and apparatus for loading and executing program code at a micro-processor are disclosed. In this method, a monitoring procedure is performed to monitor whether the micro-processor receives a loading request corresponding to a target program code. If the loading request is received, the target program code is loaded from an external memory into an internal memory of the micro-processor. The micro-processor is then rebooted to enter a first mode in which the target program code in the internal memory is to be executed. | 11-12-2009 |
| 20090315673 | RFID Tag And Operating Method Thereof - An RFID tag and a method of operating the RFID tag are provided. The RFID tag comprises a memory block that stores at least one predetermined authorization code associated with an RFID reader. In this method, according to the predetermined authorization code and an approval request transmitted from the RFID reader, it is determined by the RFID tag whether the RFID reader is authenticated. When the RFID reader is not authenticated, the RFID tag is controlled to not respond to a subsequent request transmitted from the RFID reader. As a result, the risk that data in the RFID tag may be illegally acquired by an unauthorized RFID reader is reduced. | 12-24-2009 |
| 20100052696 | Chip Testing Apparatus and Testing Method Thereof - A chip testing apparatus and a chip testing method are provided. The chip testing apparatus includes a command generating module, a transceiving module and a control module. When the command generating module generates a first test command, the transceiving module transmits the first test command to a radio frequency identification (RFID) chip and receives a target test result from the RFID chip. The control module determines whether the target test result complies with a reference test result. When the determination result of the control module is no, the control module controls the command generating module to generate a second test command for retesting the RFID chip. | 03-04-2010 |
| 20100066510 | Control Method for RFID Tag and RFID System Thereof - A control method for a radio frequency identification (RFID) tag is provided. The control method includes steps of prompting a plurality of RFID tags to enter a ready state; enabling a first RFID tag from the RFID tags to enter an accessible stage, and providing a first identification code to the first RFID tag; and commanding the first RFID tag to enter a standby state from the accessible stage. | 03-18-2010 |
| 20100073144 | Method and Circuit for Accessing RFID Tag - A radio frequency identification (RFID) tag access method and a circuit applied to an RFID tag to determine whether to respond to a command sent by a reader are provided. According to the access method, an extra reference value is used for adjusting a parameter or a count value, so as to increase or decrease the probability of generating a condition matching with a command sent by the reader. Therefore, the probability of the tag being accessed is adjusted, and the tag carrying urgent information shall be accessed prior to the tag without urgent information. | 03-25-2010 |
| 20100134258 | Method and System of Utilizing RFID Tags for Jointly Processing Task - A method of utilizing RFID tags for jointly processing a task and an associated system are provided. The method includes causing a plurality of RFID tags to enter a ready state, causing the RFID tags to enter an accessible state in turn, transmitting the task to the RFID tags, utilizing the RFID tags to jointly process the task, and reading a result from the RFID tags having processed the task. | 06-03-2010 |
| 20100182122 | RFID Tag and Operating Method Thereof - A radio frequency identification (RFID) tag and a method for operating the RFID tag are provided. The method includes steps of receiving a read command, generating a mode parameter, selecting a simulation situation from a situation group according to the mode parameter, and selectively generating a response signal according to the simulation situation. The situation group includes a first situation and a second situation. The response signal includes virtual identification (ID) information or virtual content information stored in the RFID tag. | 07-22-2010 |
| 20100225445 | RFID SYSTEM WITH RFID READERS AND OPERATING METHOD THEREOF - A radio frequency identification (RFID) system includes a host, a signal translating device and a plurality of RFID readers. The signal translating device includes a network receiving/transmitting module and an RFID receiving/transmitting module. The network receiving/transmitting module receives a control signal via a network and generates a translated signal according to the control signal. The RFID receiving/transmitting module generates an access command according to the translated signal, and transmits the access command via an RF signal. The plurality of RFID readers selectively generates an access signal or a relay access command according to the access command. | 09-09-2010 |
| 20100225446 | RFID APPARATUS, WIRELESS NETWORK PLATFORM, AND OPERATING METHOD THEREOF - A radio frequency identification (RFID) apparatus includes a transmitting/receiving module and a determining module. When the transmitting/receiving module receives a radio frequency (RF) signal comprising a relay command, the determining module determines whether destination information of the relay command corresponds to the RFID apparatus and selectively transmits the content of the RF signal via the transmitting/receiving module. | 09-09-2010 |
