    摘要: System and method for disabling a RFID tag. A preferred embodiment comprises attenuating a signal received at an antenna of the RFID tag based upon a status of the RFID tag and responding to an instruction in the received signal if the attenuated signal is detectable. The attenuation of the received signal requires that the received signal have a signal strength greater than a specified threshold in order for the instruction in the received signal to be detectable. This means that for a given signal transmit power, the RFID tag must be within a certain distance from a RFID reader attempting to retrieve information from the RFID tag. By setting the attenuation amount at a sufficiently high level, the method ensures that the RFID reader must be substantially adjacent to the RFID tag, preventing the unintended retrieval of unique identification information by RFID readers remotely located from the RFID tag.

    摘要: Systems and methods are disclosed to for detecting movement of an object. In one embodiment, a system is disclosed to detect movement of an object (e.g., a tire). The system includes a sensor that is operative to sense at least a pressure condition within an enclosed space of the object based on an operating mode of the system. A control system controls the operating mode of the system based at least in part on whether movement of the object is detected. The movement of the object is detected based on a variation in the at least a pressure condition over time. The system can be implemented as part of a tire pressure monitoring system.

    摘要: System and method for integrated circuit manufacturing. A preferred embodiment comprises transmitting a first set of data to integrated circuits (ICs) while they are in an on-wafer state and having each IC store the first set of data into memory, transmitting a second set of data to the ICs and having the ICs compare the second set of data with the first set of data stored in the memory, reading out the results of the comparisons, and marking an IC as being defective if the comparison indicates that that the first set of data did not match the second set of data. Each IC features an antenna formed in the scribe line region adjacent to the IC so that communications can take place while the IC remains on the wafer without the need to use electrical probes.
