    摘要: A merchandise control device is described that can be attached to a light emitting diode (“LED”) light bulb. A radio frequency identification (“RFID”) circuit located within the LED light bulb is configured to respond to an interrogating radio frequency (RF) signal at a point of sale. An antenna provided on an external surface of the LED light bulb, or on a sheet attached to the LED light bulb, has an electrical connection that communicates the RF signal to the RFID device. The RFID device is configured to enable function of the LED light bulb upon receiving a security code from the RF signal that matches a security code stored in the RFID device.

    摘要: A wireless control device is described that single chip passive wireless control integrated circuit device. The device is coupled to an antenna configured to receive a radio signal and comprises a radio frequency transceiver circuit fabricated on a semiconductor substrate of an integrated circuit device and configured to extract information from the radio signal and a processor fabricated on the semiconductor substrate and configured to receive the information extracted from the radio signal and to respond to a command encoded in the information.

    摘要: RFID tags are used for many purpose including tracking. RFID interrogators are used to retrieve information from tags. In many applications, RFID interrogators and RFID tags remain stationary during interrogation. Regions of low energy due to interference from either additional antenna or reflections from RFID tags and objects can impede or prohibit the reading of RFID tags residing in such regions. Stirring of the generated electromagnetic field is a method of moving around the regions of low energy, where tags can not be read, during the interrogation process. Mechanical stirring is accomplished by introducing a conductor into the electromagnetic field and moving it about in the field. Solid state stirring is accomplished by introducing a variable conductor into the field and varying the conductivity of the variable conductor. Mathematical stirring is accomplished by use of a plurality of antenna and controlling the phase difference between the antenna in a configuration known as phased antenna arrays.

    摘要: RFID tags are used for many purpose including tracking. RFID interrogators are used to retrieve information from tags. In many applications, a plurality of RFID interrogators are required. Synchronization between interrogators in the same theatre of operation is critical to ensure that their broadcasts do not interfere with each other. In fixed RFID interrogator applications, RFID interrogators can be wired together allowing a channel to synchronize the transmissions of the RFID interrogators. Methods described herein can ensure that synchronization is maintained in the event of the failure of a synchronizing master. Furthermore, additional methods for synchronizing RFID interrogators in wireless applications are described allowing synchronization in the absence of wired connections between interrogators.
