Patent number: 11774585Abstract: A device comprises a processor coupled with an ultrasonic transducer coupled which is configured to emit an ultrasonic pulse and receive returned signals received after a ringdown period of the transducer and corresponding to the emitted ultrasonic pulse. The processor is configured to evaluate the returned signals to find a candidate echo, from an object located in a ringdown blind spot area, in a time window between one and two times the ringdown period; locate multiple echoes from the object of higher order than the candidate echo; validate the candidate echo as at least a secondary echo associated of the object; and determine, based on analysis of the returned signals, an estimated distance from the transducer to the object in the ringdown blind spot area, wherein the ringdown blind spot area is located between the transducer and a closest distance at which objects can be sensed by the transducer.Type: GrantFiled: December 26, 2021Date of Patent: October 3, 2023Assignee: InvenSense, Inc.Inventors: Florence Gris, Agnes Duval

Publication number: 20220057498Abstract: A device comprises a processor coupled with an ultrasonic transducer which is configured to emit an ultrasonic pulse and receive corresponding returned signals associated with a distance range of interest in a field of view of the ultrasonic transducer. The processor is configured to: remove a low frequency component from the returned signals to achieve modified returned signals; calculate, from the modified returned signals, a variation in amplitude; determine a quantification of the variation in amplitude for a first subset of the modified returned signals associated with a first subrange of the distance range of interest; employ the quantification to correct for changes in the first subset to achieve first normalized sensor data for the first subrange, where the first normalized sensor data is sensitive to occurrence of change over time in the first subrange; and detect a moving object in the first subrange using the first normalized sensor data.Type: ApplicationFiled: August 21, 2020Publication date: February 24, 2022Applicant: Chirp Microsystems, Inc.Inventors: Agnes DUVAL, Joe YOUSSEF

Publication number: 20180339208Abstract: A method for analyzing the game of a user of a racket (Ra) includes detecting an impact on the racket (Ra) from representative measurements of a shock to the racket (Ra) provided by a sensor assembly comprising at least one sensor sensitive to shocks linked to the racket (Ra) in a fixed manner in terms of movement. A moment of impact is associated with a detected impact, from the measurements transmitted by the sensor assembly. The impacts that are not related to strokes from a set of pre-determined strokes are eliminated on the basis of angular rotational velocity measurements, provided by a gyrometer (G) of the sensor assembly with at least one measurement axis and linked to the racket (Ra) in a fixed manner in terms of movement, taken during an interval of time around said moment of impact.Type: ApplicationFiled: February 23, 2018Publication date: November 29, 2018Inventors: Lubin Kerhuel, Cyrille Soubeyrat, Joe Youssef, Anne Frassati, Agnes Duval, Sebastien Riccardi

Publication number: 20150120021Abstract: A method for analyzing the game of a user of a racket (Ra) includes detecting an impact from representative measurements of a shock to the racket (Ra) provided by a sensor assembly. The sensor assembly includes at least one sensor sensitive to shocks and is connected to the racket (Ra). A moment of impact is associated with a detected impact, using the measurements transmitted by the sensor assembly. Impacts that are not related to strokes from a set of pre-determined strokes are eliminated on the basis of angular rotational velocity measurements, provided by a gyrometer (G) of the sensor assembly with at least one measurement axis and linked to the racket, taken during an interval of time around the moment of impact.Type: ApplicationFiled: April 26, 2013Publication date: April 30, 2015Inventors: Lubin Kerhuel, Cyrille Soubeyrat, Joe Youssef, Anne Frassati, Agnes Duval, Sebastien Riccardi
