Publication number: 20240065631Abstract: In some aspects, a user device may initiate a biometric measurement operation relating to a user of the user device. The user device may monitor, using a pressure sensor of the user device, whether a pressure at an interface between a body of the user and the user device is within a range used for obtaining data for a biometric measurement. The user device may provide an indication of whether the user is to adjust the pressure based on whether the pressure is within the range. The user device may obtain the data for the biometric measurement. Numerous other aspects are described.Type: ApplicationFiled: August 25, 2022Publication date: February 29, 2024Inventors: Emily Kathryn BROOKS, John Keith SCHNEIDER, Krishna BUSKA

Publication number: 20230252815Abstract: The described techniques support a sensing scheme for electromagnetic excitation in ultrasonic imaging sensors. A biological tissue may be sensed and imaged using an electromagnetic excitation process to generate ultrasonic waves, such as, within the tissue. A component of a device may generate one or more pulses of electromagnetic waves, which may encounter and enter the biological tissue. The electromagnetic waves may excite the biological tissue and generate ultrasonic waves via expansion and contraction of the tissue upon heating. The ultrasonic waves may propagate within the biological tissue and may be sensed by an ultrasonic receiver array. The ultrasonic waves may be converted to pixel image data of a biometric image and may be used for biometric authentication. This process may be repeated to reconstruct an image of the finger at multiple plane slices of the finger.Type: ApplicationFiled: April 17, 2023Publication date: August 10, 2023Inventors: Jack Conway Kitchens, John Keith Schneider, Evan Michael Breloff, Emily Kathryn Brooks, Stephen Michael Gojevic, James Anthony Miranto, Alexei Stoianov, Fitzgerald John Archibald

Publication number: 20220175258Abstract: Some disclosed methods involve controlling, via a control system, a light source system to emit a plurality of light pulses into biological tissue at a pulse repetition frequency, the biological tissue including blood and blood vessels at depths within the biological tissue. Such methods may involve receiving, by the control system, signals from the piezoelectric receiver corresponding to acoustic waves emitted from portions of the biological tissue, the acoustic waves corresponding to photoacoustic emissions from the blood and the blood vessels caused by the plurality of light pulses. Such methods may involve detecting, by the control system, heart rate waveforms in the signals, determining, by the control system, a first subset of detected heart rate waveforms corresponding to vein heart rate waveforms and determining, by the control system, a second subset of detected heart rate waveforms corresponding to artery heart rate waveforms.Type: ApplicationFiled: December 7, 2020Publication date: June 9, 2022Inventors: Jack Conway KITCHENS, John Keith SCHNEIDER, Evan Michael BRELOFF, Emily Kathryn BROOKS, Stephen Michael GOJEVIC, Fitzgerald JOHN ARCHIBALD, Alexei STOIANOV, Shounak Uday GORE, Nicholas Ian BUCHAN

Patent number: 11346930Abstract: 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: GrantFiled: August 7, 2019Date of Patent: May 31, 2022Assignee: QUALCOMM IncorporatedInventors: Jack Conway Kitchens, II, John Keith Schneider, Stephen Michael Gojevic, Timothy Dickinson, Philip John Schneider, Evan Breloff, Evan Robert Hildreth

Patent number: 11306829Abstract: A low pressure, low operating force valve, for applications where automated valves are used, having reduced power requirements for an associated actuator. A low torque ball valve of a fixed ball valve configuration for low to medium pressure applications, such as for an electric motor actuated residential shutoff valve where pressures are typically below 100 psi, and commonly less than 60 psi, for example. The valve can be open or shut using a smaller electric motor than would be required for a conventional residential floating ball shutoff valve of a similar size. As such, the power requirements of the electric motor or other actuator are reduced allowing for the use of smaller motors, smaller power supplies and overall more efficient operation.Type: GrantFiled: October 16, 2020Date of Patent: April 19, 2022Assignee: LeakSmart Inc.Inventors: John C. Holzheimer, Keith Schneider
