Title: Communications circuit including a linear quadratic estimator

Abstract

A circuit includes a linear quadratic estimator (LQE) configured to receive a plurality of measurements a signal. The LQE is configured to weight the measurements based on their respective uncertainties to produce weighted averages. The circuit further includes a controller coupled to the LQE and configured to selectively adjust at least one data link parameter associated with a communication channel in response to receiving the weighted averages.

Polarization tracking system for free-space optical communication, including quantum communication

Patent Nordholt, Jane Elizabeth; Newell, Raymond Thorson; Peterson, Charles Glen; ...

Quantum communication transmitters include beacon lasers that transmit a beacon optical signal in a predetermined state of polarization such as one of the states of polarization of a quantum communication basis. Changes in the beacon polarization are detected at a receiver, and a retarder is adjusted so that the states of polarization in a received quantum communication optical signal are matched to basis polarizations. The beacon and QC signals can be at different wavelengths so that the beacon does not interfere with detection and decoding of the QC optical signal.

Engine lubrication circuit including two pumps

Patent Lane, William H.

A lubrication pump coupled to the engine is sized such that the it can supply the engine with a predetermined flow volume as soon as the engine reaches a peak torque engine speed. In engines that operate predominately at speeds above the peak torque engine speed, the lubrication pump is often producing lubrication fluid in excess of the predetermined flow volume that is bypassed back to a lubrication fluid source. This arguably results in wasted power. In order to more efficiently lubricate an engine, a lubrication circuit includes a lubrication pump and a variable delivery pump. The lubrication pump ismore » « less

Tone signal generator for producing multioperator tone signals using an operator circuit including a waveform generator, a selector and an enveloper

Patent Dong, Qiujie [Austin, TX]; Jenkins, Michael V [Austin, TX]; Bernadas, Salvador R [Austin, TX]

A frequency modulation (FM) tone signal generator for generating a FM tone signal is disclosed. The tone signal generator includes a waveform generator having a plurality of wave tables, a selector and an enveloper. The waveform generator furnishes a waveform signal in response to a phase angle address signal. Each wave table stores a different waveform. The selector selects one of the wave tables in response to a plurality of selection signals such that the selected wave table largely provides the waveform signal upon being addressed largely by the phase angle address signal. Selection of the selected wave table variesmore » « less

Circuit that includes a physically unclonable function

Patent Bauer, Todd; Hamlet, Jason; Birmingham, Ryan Michael; ...

Described herein are various technologies pertaining to authentication of integrated circuits by using external factors to affect or modify an output of a physically unclonable function (PUF) circuit. In an example, the output of the PUF circuit in response to a challenge signal can be sensitive to changes in environmental factors. In another example, the output of the PUF circuit can be sensitive to user-selectable configuration parameters of the PUF circuit. In yet another example, the output of the PUF circuit can be modified by additional circuitry external to the PUF circuit based upon one or more selectable or configurablemore » « less

Microelectromechanical accelerometer with resonance-cancelling control circuit including an idle state

Patent Chu, Dahlon D [Albuquerque, NM]; Thelen, Jr., Donald C. (Bozeman, MT); Campbell, David V [Albuquerque, NM]

A digital feedback control circuit is disclosed for use in an accelerometer (e.g. a microelectromechanical accelerometer). The digital feedback control circuit, which periodically re-centers a proof mass in response to a sensed acceleration, is based on a sigma-delta (.SIGMA..DELTA.) configuration that includes a notch filter (e.g. a digital switched-capacitor filter) for rejecting signals due to mechanical resonances of the proof mass and further includes a comparator (e.g. a three-level comparator). The comparator generates one of three possible feedback states, with two of the feedback states acting to re-center the proof mass when that is needed, and with a third feedbackmore » « less
