  • Patent number: 7904842
    Abstract: An implementation of a logic description is improved. The implementation has two signals coupled to two inputs of a fanout-free cone. A swap function is determined of the inputs of the fanout-free cone. The swap function indicates whether there is a difference at an output of the fanout free cone between the fanout-free cone with and without swapping the two signals between the two inputs of the fanout-free cone. A do-not-care function of the inputs of the fanout-free cone is determined for the logic description. The do-not-care function indicates that a modification of the output of the fanout-free cone is not observable at the primary outputs of the logic description. A modified implementation of the logic description is output in response to the do-not-care function covering the swap function. The modified implementation of the logic description has the two signals swapped between the two inputs of the fanout-free cone.

  • Patent number: 7603646
    Abstract: Various approaches for generating an implementation of an electronic circuit design are disclosed. In one approach, one or more configuration bits that have don't care conditions are identified for a LUT block of a design. A dynamic power state for a subset of a first level of logic devices in the LUT block is determined as a function of each identified configuration bit that has a don't care condition. A dynamic power state for a subset of a second level of logic devices is determined as a function of the determined power state for the first level of logic devices. A respective value for each identified configuration bit of the LUT is selected in response to the determined dynamic power states. The respective value is placed into the design for each identified configuration bit.

  • Publication number: 20070268138
    Abstract: An RFID system and method utilizes the power level of messages received from an RFID device for monitoring and/or locating and/or tracking the RFID device, e.g., and typically an object associated with the RFID device. The power level of received messages may be indicated by power level information contained in the message, or by the strength of the received signal carrying the message, or by both. The RFID system and method may be employed to monitor a condition of an object, e.g., a closable container, as to whether it is and/or has been closed or not, including being tampered with. Messages received from the RFID device, as well as an indication of a condition, may be relayed to a remote location.

  • Publication number: 20070013519
    Abstract: A system for monitoring a container comprises an RFID device interior the container and a receiving device exterior the container. The RFID device transmits messages each including unique identifying information, and the receiving device exterior the container receives and stores and/or relays messages received from the RFID device interior the container. Ones of the messages transmitted by the RFID device when the container is closed are not received by the receiving device and ones of the messages transmitted by the RFID device when the container is not closed are received and stored by the receiving device, whereby the messages stored in the receiving device provide an indication of whether the container has or has not been opened. Messages may include power level codes and be transmitted at more than one power level, and may be processed for locating and/or tracking the container.
