  • Patent number: 8390433
    Abstract: A method and system for inventorying wireless transponders, specifically referred to as RFID transceiver devices. To provide higher functionality, a microcontroller is used in the RFID, along with a battery, but the clock frequency of the microcontroller is adjusted, based on external input, to minimize battery requirements. The RFID transceiver device includes at least one sensor coupled to the microcontroller. Data from the at least one sensor is stored in non-volatile memory of the microcontroller if the battery is at a predetermined low level, and is read later when the battery is at a higher level.

  • Patent number: 8258927
    Abstract: The present invention provides one or more powered wireless transponders and/or one or more passive wireless transponder devices communicating with a reader/interrogator and the method of efficiently inventorying these devices without the risk of eavesdropping. A reader transmits a random number and transponders generate their own random number. The transponders whose random number matches all or a part of the random number responds. If a collision occurs, the reader's random number can be changed and retransmitted until almost one transponder response is verified in a tree search algorithm. Specifically, the invention concerns a method for inventorying wireless transponders providing anti-eavesdropping anti-collision.

  • Patent number: 8248981
    Abstract: The present invention provides a method and system for establishing a highly mobile, long range secure wireless network with dynamic topologies and near full connectivity with acceptable latency using low cost, low power, compact and lightweight devices. One aspect of the system deals with a highly mobile network with dynamic network topologies and a time varying wireless medium that has neither absolute nor readily observable boundaries outside of which radio nodes are known to be unable to receive network frames, although the desirable open field boundary is 1 mile in radius from a base station node. A synchronous frequency hopping technique is used with mobile nodes that can become slave base station nodes to a master base station node to increase the effective range of the master base station without increasing the transmit power.

  • Patent number: 8027634
    Abstract: The RFID system of the present invention provides activation of a subscription based device wirelessly using a RFID system. The system for activating of a user for a subscription service comprises a first secure RFID sensor associated with a subscription-based device and a second secure RFID sensor associated with a user device. The first and second secure RFID sensors communicate with one another to establish activation of the user device. For example, the first sensor can receive an authentication value associated with the subscription service from the second RFID sensor. After activation, the subscription-based device can broadcast the subscription service to the user device. Alternatively, the user device can also have a capability to verify its separate or related subscription such as WiFi, WiMAX, GSM, CDMA or other wireless-based connectivity service.
