Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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.
