  • Publication number: 20100176840
    Abstract: A superconductor crossbar switch for connecting a plurality of inputs with a plurality of outputs, including a switching cell having an input, an output and a circuit for connecting the input with the output for bidirectionally transmitting data therebetween. The connection of the retaining and releasing circuitry of a plurality of cells enables the switch to simultaneously retain a selected cell or cells of a group of cells and disable the remaining cells of that group, whereby a subsequent query on a disabled cell is inoperative until the selected cell or cells is released. The crossbar switch is characterized by latency on the order of nanoseconds, a data rate per channel on the order of gigabits per second, essentially zero crosstalk, and detection of contention in nanoseconds or less and resolution of contention in nanoseconds or less.

  • Patent number: 6538616
    Abstract: The present invention is an antenna with a cubic core. A first conductor is wound around the core's first axis. A first dielectric layer is placed around the first conductor. A first electrical shield is placed around the first dielectric layer. A second dielectric layer is placed around the first electrical shield. A second conductor is wound around the second dielectric layer in the core's second axis. A second electrical shield is placed around the third dielectric layer. A fourth dielectric layer is placed around the second electrical shield. A third conductor is wound around the fourth dielectric layer in the core's third plane. A fifth dielectric layer is placed around the third conductor. A third electrical shield is placed around the fifth dielectric layer. Each conductor is connected to an amplifier. Each amplifier is connected to an anti-aliasing filter. Each anti-aliasing filter is connected to an analog-to-digital converter.
