Patent number: 11651610Abstract: An ultrasonic fingerprint sensor in a mobile device is operated to capture an initial snapshot of reflection from a finger's surface, of acoustic energy transmitted at a first frequency. Additionally, the ultrasonic fingerprint sensor is operated repeatedly to capture over time, a sequence of sets, each set including one or more additional snapshots of reflection from one or more depths within the finger, of acoustic energy transmitted at a second frequency significantly lower than the first frequency. Measurements in the additional snapshots are processed to determine whether any signal oscillating at a rate in a normal range for heart rate or respiration rate is present. When a signal is found, its rate may be used in several ways, e.g. to enable functionality when a fingerprint in the initial snapshot matches a reference fingerprint, or to identify and track a heart rate (or a respiration rate) based on the signal's rate.Type: GrantFiled: May 31, 2018Date of Patent: May 16, 2023Assignee: QUALCOMM IncorporatedInventors: Lior Maor, Meir Agassy, Boaz Castro

Patent number: 10733409Abstract: Systems, methods and apparatus for configuring a fingerprint sensor to operate in a capacitive sensing mode and an ultrasonic sensing mode are disclosed. A fingerprint sensor may be configured to operate in a capacitive sensing mode by driving a sensing electrode using a controller. In some implementations, an object positioned on or near the sensing electrode may be detected using the fingerprint sensor in the capacitive sensing mode, and the controller can drive electrodes of the fingerprint sensor differently to configure the fingerprint sensor to operate in an ultrasonic sensing mode. In some implementations, an applications processor may be instructed to authenticate a fingerprint of the object from image data obtained when the fingerprint sensor is operating in the ultrasonic sensing mode. In some implementations, a display of a mobile device containing the fingerprint sensor may be unlocked, or the mobile device may be woken up when the fingerprint is authenticated.Type: GrantFiled: November 7, 2018Date of Patent: August 4, 2020Assignee: QUALCOMM IncorporatedInventors: Sandeep Louis D'Souza, Vadim Winebrand, Ashish Hinger, Paul Penchin Pan, Meir Agassy, Yizhaq Abudi, Micah Timothy Lawrence, Jong Soo Kim, Sherman Sebastian Antao, Bo-Ren Wang, Masoud Roham, Lennart Karl Mathe, Nathan Felix Altman, Suryaprakash Ganti, David William Burns

Patent number: 10685204Abstract: An apparatus may include an ultrasonic fingerprint sensor system and a control system. The control system may be configured for obtaining, via a scan of the fingerprint sensor system, current fingerprint image data from a surface of a target object, for extracting current fingerprint features from the current fingerprint image data and for determining whether the current fingerprint features match features of a previously-acquired fingerprint enrollment template. If there is a match, the control system may be configured for obtaining, via one or more additional scans of the fingerprint sensor system, current subsurface image data from a subsurface of the target object, for calculating an estimated biometric age of the target object, based at least in part on the current subsurface image data and for determining whether the estimated biometric age of the target object matches a previously-estimated biometric age.Type: GrantFiled: July 27, 2018Date of Patent: June 16, 2020Assignee: QUALCOMM IncorporatedInventors: Lior Maor, Meir Agassy, Boaz Castro
