  • Patent number: 10949024
    Abstract: A pulse of terahertz radiation is transmitted through a touch panel formed of a dielectric material. The pulse generates an employable evanescent field in a region adjacent to a touch surface of the touch panel. The terahertz radiation has a frequency range between 0.1 terahertz and 10 terahertz. A reflected pulse is generated from an object located within the region adjacent to the touch surface of the touch panel. A position is triangulated of the object on the touch surface of the touch panel, based at least in part on the reflected pulse.

  • Publication number: 20170228484
    Abstract: A system and method is disclosed for verifying semiconductor circuit layouts. A resistor stick network model of the semiconductor circuit layout is generated from a low frequency extraction of the circuit. The resistor stick network then can be used to determine open or short in the circuit by comparing the pairwise terminal resistance of each circuit node thus eliminating open/short failures in the circuit.

  • Patent number: 8994585
    Abstract: A method is provided. A first edge on a first gating signal is generated, and a local oscillator and a shared clocking circuit with the first edge on the first gating signal. A second edge on a second gating signal is generated following the first edge on the first gating signal, and a receiver circuit is activated with the second edge on the second gating signal, where the receiver circuit includes a mixer. A transmit pulse following the first edge on the first gating signal is generated with the transmit pulse having a third edge. A switch that short circuits outputs of the mixer is then released following the later of the third edge of the transmit pulse and a delay.

  • Patent number: 8786338
    Abstract: A method for providing a plurality of narrow pulses is provided. A first pulse having a first width is received by a delay line having a plurality of delay cells. This first pulse has a first width. In response to this first pulse, a plurality of second pulses is generated by the delay line, where each second pulse has a second width that is less than the first width. First and second delay pulses are also generated by the delay line, and a delay for each delay cell in the delay line can then be adjusted if a rising edge of the second delay pulse is misaligned with a falling edge of the first delay pulse.
