  • RFID device for object monitoring, locating, and tracking
    Patent number: 7319397
    Abstract: An RFID monitoring arrangement comprises a first RFID device and a second RFID device for monitoring the first RFID device. The first RFID device transmits at least two messages each including unique identifying information and a power level code, wherein the transmitter power level corresponds to the power level represented by the power level code in each transmitted message. The second RFID device receives messages transmitted by the first RFID device and processes the identifying information and the power level code to provide an indication of a condition. Messages received from said first RFID device, the indication of a condition, or both the messages received from said first RFID device and the indication of a condition, may be relayed to a remote location.

  • Electronic voting apparatus, system and method
    Patent number: 7036730
    Abstract: The voting apparatus, system and method of the invention provides at least two independently means for recording and counting votes, i.e. one associated with the voting apparatus and one separate therefrom. A preferred voting apparatus, system and method provides triple data redundancy in that each vote is recorded by three independent and verifiable means: i.e. by recording in an electronic memory included in each voting machine or system, by recording in the memory of a smart card separate from the voting machine or system, and by a confirmatory printed record for each voter. The invention utilizes a voting session identifier to provide transparency of each and every vote and to maintain the anonymity of each and every vote and voter.
