Patent number: 10497748Abstract: An ultrasonic sensor pixel includes a substrate, a piezoelectric micromechanical ultrasonic transducer (PMUT) and a sensor pixel circuit. The PMUT includes a piezoelectric layer stack including a piezoelectric layer disposed over a cavity, the cavity being disposed between the piezoelectric layer stack and the substrate, a reference electrode disposed between the piezoelectric layer and the cavity, and one or both of a receive electrode and a transmit electrode disposed on or proximate to a first surface of the piezoelectric layer, the first surface being opposite from the cavity. The sensor pixel circuit is electrically coupled with one or more of the reference electrode, the receive electrode and the transmit electrode and the PMUT and the sensor pixel circuit are integrated with the sensor pixel circuit on the substrate.Type: GrantFiled: October 12, 2016Date of Patent: December 3, 2019Assignee: QUALCOMM IncorporatedInventors: Hrishikesh Vijaykumar Panchawagh, Suryaprakash Ganti, Kostadin Dimitrov Djordjev, David William Burns, Timothy Alan Dickinson, Donald William Kidwell, Jr., Ravindra Vaman Shenoy, Jon Bradley Lasiter, Hao-Yen Tang, Yipeng Lu

Publication number: 20190361104Abstract: An object having an outer surface (e.g. a friction-ridge surface of a finger) and internal parts (e.g. tissue layer, papillae, blood vessels, fat, muscle, nail and bone) is scanned by a system having a transmitter, receiver and computer. One such system has a substantially planar piezoelectric transmit-layer, an ultrasonic receiver array having a plurality of receivers, and a platen. The transmit layer is caused to produce an ultrasound plane-wave traveling toward the object residing on the platen. Using the ultrasonic receiver, ultrasonic energy that has been reflected from the object is detected. The detected ultrasonic energy is analyzed to provide an analysis result, and the analysis result is compared to a template. A determination is made as to whether the analysis result and the template are similar, and the object is declared to be alive if the analysis result is determined to be similar to the template.Type: ApplicationFiled: August 7, 2019Publication date: November 28, 2019Inventors: Jack KITCHENS, John Keith SCHNEIDER, Stephen Michael GOJEVIC, Timothy Alan DICKINSON, Philip John SCHNEIDER, Evan Michael BRELOFF, Evan Robert HILDRETH

Patent number: 10444335Abstract: Methods and systems of determining whether an object is alive, and therefore part of a live individual, are described. An object having an outer surface (e.g. a friction-ridge surface of a finger) and internal parts (e.g. tissue layer, papillae, blood vessels, fat, muscle, nail and bone) is scanned by a system having a transmitter, receiver and computer. One such system has a substantially planar piezoelectric transmit-layer, an ultrasonic receiver array having a plurality of receivers, and a platen. The transmit layer is caused to produce an ultrasound plane-wave traveling toward the object residing on the platen. Using the ultrasonic receiver, ultrasonic energy that has been reflected from the object is detected. The detected ultrasonic energy is analyzed to provide an analysis result, and the analysis result is compared to a template.Type: GrantFiled: June 21, 2017Date of Patent: October 15, 2019Assignee: QUALCOMM IncorporatedInventors: Jack Conway Kitchens, II, John Keith Schneider, Stephen Michael Gojevic, Timothy Alan Dickinson, Philip John Schneider, Evan Michael Breloff, Evan Robert Hildreth

Publication number: 20170323130Abstract: An apparatus may include an ultrasonic receiver array, an ultrasonic transmitter and a control system capable of controlling the ultrasonic transmitter to transmit first ultrasonic waves in a first direction and to simultaneously transmit second ultrasonic waves in a second direction that is opposite the first direction. The control system may be capable of distinguishing first reflected waves from second reflected waves, the first reflected waves corresponding to reflections of the first ultrasonic waves that are received by the ultrasonic receiver array and the second reflected waves corresponding to reflections of the second ultrasonic waves that are received by the ultrasonic receiver array. The control system may be capable of determining first image data corresponding to the first reflected waves and of determining second image data corresponding to the second reflected waves.Type: ApplicationFiled: May 6, 2016Publication date: November 9, 2017Inventors: Timothy Alan Dickinson, Nicholas Ian Buchan, David William Burns, John Keith Schneider, Muhammed Ibrahim Sezan
