  • Patent number: 8779968
    Abstract: A system for measuring the range to an RFID tag including situations containing high clutter and multi-path signals is disclosed. The system includes an RFID reader; an RFID tag; and a coordinated pulse radar system. In the system the RFID reader causes the tag to respond to received signals in a first backscatter state at a first time and a second backscatter state at a second time. The pulsed radar system transmits short pulses coordinated by the backscatter state of the RFID tag and the system creates a differential signal comprised of the differences between radar signals obtained during the first and second states of the tag to obtain an uncorrupted measure of a round trip time of flight of said radar pulses between the pulse radar system and the RFID tag.

  • Patent number: 8427279
    Abstract: A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGO™ RFID backscatter transponders, SEGO™ RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.

  • Patent number: 8327300
    Abstract: Disclosed is a method, system, and article of manufacture for a one-pass approach for implementing metal-fill for an integrated circuit. Also disclosed is a method, system, and article of manufacture for implementing metal-fill that is coupled to a tie-off connection. An approach that is disclosed comprises a method, system, and article of manufacture for implementing metal-fill having an elongated shape that corresponds to the length of whitespace. Also disclosed is the aspect of implementing metal-fill that matches the routing direction. Yet another disclosure is an implementation of a place & route tool incorporating an integrated metal-fill mechanism.

  • Publication number: 20100203356
    Abstract: A magnesium alloy compound type thermal metal material includes a heat dissipation surface layer formed of a magnesium alloy, a contact surface layer formed of gold, platinum, silver, or copper alloy, and a fusion layer, which is an eutectic structure joined between the heat dissipation surface layer and the contact surface layer under and formed therebetween subject to application of a high temperature and a high pressure, such that the thermal conductivity metal alloy of the contact surface layer absorbs heat energy quickly from the heat source and transfers absorbed heat energy to the heat dissipation surface layer for quick dissipation; the internal molecules of the product are joined tightly together subject to the applied pressure, and the surface of the product allows for electroplating.

  • Patent number: 7483789
    Abstract: Systems and methods are provided for complementary navigation devices with various integrated positioning functionality. The navigation method includes providing a first navigation device. The first navigation device includes a triangulation positioning functionality. The method includes providing a second navigation device adapted to communicate with the first navigation device. The second navigation device includes one or more dead reckoning positioning components. The method further includes resolving a position of the first and the second navigation devices. Resolving the position includes using the one or more dead reckoning positioning components in complement to the triangulation positioning functionality to determine the position when the triangulation positioning functionality is degraded.
