Patent number: 10547805Abstract: A pattern generator circuit includes a high-speed shift register and a non-overlap generator. The shift register is programmable to produce a pulse train of pulses having a defined pulse duration and a defined pulse-to-pulse interval. The non-overlap generator deserializes the incoming pulse train, and it produces a time-separated reset pulse based on the pulse train. The shift register is configured to permit the pulse durations and pulse-to-pulse interval to be selected arbitrarily over specified ranges in increments of a basic time unit that depends on the oscillator period.Type: GrantFiled: July 11, 2018Date of Patent: January 28, 2020Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Marcos O. Sanchez, Liam D. Claus, Gideon Robertson, Sean Pearson, Andrew Montoya

Patent number: 10057521Abstract: A high-speed CMOS camera includes an array of pixel circuits coupled to a photodiode array, an oscillator circuit, and a pattern generator circuit. The pattern generator circuit includes a high speed shift register and a non-overlap generator. The shift register is programmable to produce a pulse train of trigger pulses that defines an interframe and a frame's shutter duration. The non-overlap generator deserializes the incoming pulse train of trigger pulses, and it produces a time-separated reset pulse based on the pulse train of trigger pulses. The shift register is configured to permit the frame durations and the interframe times to be selected arbitrarily over specified ranges in increments of a basic time unit that depends on the oscillator period.Type: GrantFiled: August 11, 2016Date of Patent: August 21, 2018Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Marcos O. Sanchez, Liam D. Claus, Gideon Robertson, John L. Porter, Jr., Sean Pearson, Kurt Wessendorf, Tom Gurrieri, Thomas Hill, Andrew Montoya, Doug Trotter

Patent number: 8285394Abstract: A demultiplexer circuit is disclosed which can be used with a conventional neural stimulator to extend the number of electrodes which can be activated. The demultiplexer circuit, which is formed on a semiconductor substrate containing a power supply that provides all the dc electrical power for operation of the circuit, includes digital latches that receive and store addressing information from the neural stimulator one bit at a time. This addressing information is used to program one or more 1:2N demultiplexers in the demultiplexer circuit which then route neural stimulation signals from the neural stimulator to an electrode array which is connected to the outputs of the 1:2N demultiplexer. The demultiplexer circuit allows the number of individual electrodes in the electrode array to be increased by a factor of 2N with N generally being in a range of 2-4.Type: GrantFiled: July 14, 2009Date of Patent: October 9, 2012Assignee: Sandia CorporationInventors: Kurt O. Wessendorf, Murat Okandan, Sean Pearson
