Patent number: 12109885Abstract: A driver intoxication test system is provided for a vehicle including: a quick intoxication pre-test subsystem for quickly determining whether there is reason to suspect the driver may be intoxicated; an intoxication validation test subsystem for determining whether the driver is intoxicated; and a controller is configured to determine whether the quick intoxication pre-test subsystem has detected a reason to suspect the driver may be intoxicated. When a reason to suspect the driver may be intoxicated has been detected, an intoxication validation test is conducted and it is determined whether the driver has passed the intoxication validation test. When a reason to suspect the driver may be intoxicated has not been detected, the controller does not instruct the intoxication validation test subsystem to conduct an intoxication validation test.Type: GrantFiled: March 9, 2023Date of Patent: October 8, 2024Assignee: GENTEX CORPORATIONInventor: Robert Steel

Patent number: 11134330Abstract: Embodiments of the invention determine a speech estimate using a bone conduction sensor or accelerometer, without employing voice activity detection gating of speech estimation. Speech estimation is based either exclusively on the bone conduction signal, or is performed in combination with a microphone signal. The speech estimate is then used to condition an output signal of the microphone. There are multiple use cases for speech processing in audio devices.Type: GrantFiled: July 12, 2019Date of Patent: September 28, 2021Assignee: Cirrus Logic, Inc.Inventors: David Leigh Watts, Brenton Robert Steele, Thomas Ivan Harvey, Vitaliy Sapozhnykov

Patent number: 10490208Abstract: A signal processing device for configurable voice activity detection. A plurality of inputs receive respective microphone signals. A microphone signal router configurably routes the microphone signals. At least one voice activity detection module receives a pair of microphone signals from the router, and produces a respective output indicating whether speech or noise has been detected by the voice activity detection module in the respective pair of microphone signals. A voice activity decision module receives the output of the voice activity detection module(s) and determines whether voice activity exists in the microphone signals. A spatial noise reduction module receives microphone signals from the microphone signal router, and performs adaptive beamforming based in part upon the output of the voice activity decision module, and outputs a spatial noise reduced output. The device permits simple configurability to deliver spatial noise reduction for one of a wide variety of headset form factors.Type: GrantFiled: April 5, 2018Date of Patent: November 26, 2019Assignee: Cirrus Logic, Inc.Inventors: Brenton Robert Steele, Hu Chen, Ben Hutchins

Patent number: 10418048Abstract: A device for noise estimation comprises a first microphone capturing a nominal speech signal, and a second microphone capturing a nominal noise signal. A generalized sidelobe canceller of the device applies spatial noise reduction, and comprises a blocking matrix filter to adaptively process the nominal speech signal to produce a speech cancellation signal, a node for subtracting the speech cancellation signal from the nominal noise signal to produce a noise reference signal, a noise cancellation filter to adaptively filter the noise reference signal to produce a noise cancellation signal; and a node for subtracting the noise cancellation signal from the nominal speech signal to produce a speech reference signal.Type: GrantFiled: April 30, 2018Date of Patent: September 17, 2019Assignee: Cirrus Logic, Inc.Inventors: Benjamin Hutchins, Brenton Robert Steele

Patent number: 8650237Abstract: Adaptive processing of an input signal is achieved by offline analysis, with inline processing comprising an adaptive filter. The method comprises passing the input signal through an adaptive time domain filter to produce an output signal. The input signal and/or output signal is used as an offline analysis signal. The analysis signal is transformed into a transform domain (eg frequency domain) to produce a transformed analysis signal. The transformed analysis signal is analyzed, for example by ADRO, to produce a plurality of desired gains each corresponding to a respective transform domain sub-band. A time domain filter characteristic is synthesized to at least approach the desired gains. The adaptive filter is updated with the synthesized filter characteristic. Minimum phase adaptive filter techniques are found to possess particular benefits in this scheme.Type: GrantFiled: March 24, 2010Date of Patent: February 11, 2014Assignee: Wolfson Dynamic Hearing Pty LtdInventors: Bonar Dickson, Brenton Robert Steele

Patent number: 8573823Abstract: In one embodiment, a solid-state luminaire has a strip of high power LEDs, where each LED emits light into an optical coupler. Light from the optical coupler is then coupled into a light guide. Light coupled into the light guide is mixed and guided to an exit aperture of the light guide. An optical extractor proximate the exit aperture of the light guide redirects light outward, which is optionally redirected generally downward by a secondary reflector that extends outwardly along the length of the light guide. The secondary reflector may be configured to create a variety of light-emission patterns. The luminaire may be hung from a ceiling, in track lighting, used as a pendant or pedestal fixture, or in other applications.Type: GrantFiled: August 8, 2011Date of Patent: November 5, 2013Assignee: Quarkstar LLCInventors: Wilson Dau, Robert Gardner, George Lerman, Louis Lerman, Chris Lowery, Brian D.

Patent number: 8461602Abstract: A solid state light sheet and method of fabricating the sheet are disclosed. In one embodiment, bare LED chips have top and bottom electrodes, where the bottom electrode is a large reflective electrode. The bottom electrodes of an array of LEDs (e.g., 500 LEDs) are bonded to an array of electrodes formed on a flexible bottom substrate. Conductive traces are formed on the bottom substrate connected to the electrodes. A transparent top substrate having conductors is then laminated over the bottom substrate. Various ways to connect the LEDs in series are described along with many embodiments. The light sheets may be formed to emit light from opposite surfaces of the light sheet, enabling it to be used in a hanging fixture to illuminate the ceiling as well as the floor. The light sheet provides a practical substitute for a standard 2×4 foot fluorescent ceiling fixture.Type: GrantFiled: January 31, 2011Date of Patent: June 11, 2013Assignee: Quarkstar LLCInventors: Louis Lerman, Allan Brent York, Michael David Henry, Robert Steele, Brian D.

Patent number: 8410726Abstract: A solid state lamp, such as one that can replace an incandescent light bulb, has a base portion having an electrical connector for connection to a source of power, such as an Edison-type connector for connection to the mains voltage. An AC/DC converter in the base converts the mains voltage to a suitable light emitting diode (LED) drive voltage. A plurality of receptacles on the base connects to electrodes of plug-in modules. Each plug-in module supports a plurality of low power LEDs connected in series. The strings of LEDs on different modules are connected in parallel when connected to the receptacles. The modules and base are configured to allow a user to operate the lamp with different combinations of modules to generate a desired light output from the lamp. For example, the user can recreate the lumens equivalent of a 20 W, 40 W, or 60 W bulb by using one, two, or three modules.Type: GrantFiled: February 22, 2011Date of Patent: April 2, 2013Assignee: Quarkstar LLCInventors: Wilson Dau, Louis Lerman, Allan Brent York, Robert Steele, Jacqueline Teng, George Lerman
