Patent number: 11923090Abstract: Computing systems and methods are provided for detecting skin conditions of humans. A computing device can authenticate a user via a fingerprint scan of a first skin region of the user using a three-dimensional (3D) sonic sensor. The device can generate a three-dimensional (3D) volumetric sonic measurement of a second skin region of the user based at least in part on one or more sonic pulses of the three-dimensional sonic sensor. The device can input data indicative of the 3D volumetric sonic measurement into one or more machine-learning models, generate one or more skin cancer condition identifications associated with the second skin region of the user based on one or more outputs of the one or more machine-learned models, and provide one or more outputs including the one or more skin cancer condition identifications associated with the second skin region of the user.Type: GrantFiled: July 19, 2021Date of Patent: March 5, 2024Assignee: GOOGLE LLCInventors: Dongeek Shin, William James Biederman, Shwetak Patel

Publication number: 20230277069Abstract: Generally, the present disclosure is directed to systems and methods for measuring heart rate and respiratory rate using a camera such as, for example, a smartphone camera or other consumer-grade camera. Specifically, the present disclosure presents and validates two algorithms that make use of smartphone cameras (or the like) for measuring heart rate (HR) and respiratory rate (RR) for consumer wellness use. As an example, HR can be measured by placing the finger of a subject over the rear-facing camera. As another example, RR can be measured via a video of the subject sitting still in front of the front-facing camera.Type: ApplicationFiled: March 3, 2022Publication date: September 7, 2023Inventors: Jiening Zhan, Sean Kyungmok Bae, Silviu Borac, Yunus Emre, Jonathan Wesor Wang, Jiang Wu, Mehr Kashyap, Ming Jack Po, Liwen Chen, Melissa Chung, John Cannon, Eric Steven Teasley, James Alexander Taylor, Jr., Michael Vincent McConnell, Alejandra Maciel, Allen KC Chai, Shwetak Patel, Gregory Sean Corrado, Si-Hyuck Kang, Yun Liu, Michael Rubinstein, Michael Spencer Krainin, Neal Wadhwa

Publication number: 20220218224Abstract: Various arrangements for performing radar-based measurement of vital signs. Waveform data may be received then filtered of data indicative of static objects to obtain motion-indicative waveform data. The motion-indicative waveform data may be analyzed to determine one or more frequencies of movement present within the motion-indicative waveform data. A spectral analysis may be performed on the motion-indicative waveform data to determine a spectral-analysis state of a monitored region. The spectral-analysis state of the monitored region may be determined to match a predefined spectral-analysis state during which vital sign monitoring is permitted. One or more vital signs of a monitored user present within the monitored region may be determined and output based on analyzing the motion-indicative waveform data.Type: ApplicationFiled: May 8, 2019Publication date: July 14, 2022Applicant: Google LLCInventors: Dongeek Shin, Brandon Barbello, Shwetak Patel, Anupam Pathak, Michael Dixon

Patent number: 11344214Abstract: Wearable pulse pressure wave sensing devices are presented that generally provide a non-intrusive way to measure a pulse pressure wave travelling through an artery using a wearable device. In one implementation, the device includes an array of pressure sensors disposed on a mounting structure which is attachable to a user on an area proximate to an underlying artery. Each of the pressure sensors is capable of being mechanically coupled to the skin of the user proximate to the underlying artery. In addition, there are one or more arterial location sensors disposed on the mounting structure which identify a location on the user's skin likely overlying the artery. A pulse pressure wave is then measured using the pressure sensor of the array closest to the identified location.Type: GrantFiled: June 29, 2020Date of Patent: May 31, 2022Assignee: Microsoft Technology Licensing, LLCInventors: T.

Publication number: 20220167481Abstract: Systems and techniques are provided for light source status detection. Ambient light values generated by an ambient light sensor of a device in an environment over a period of time may be received. A first light source model for the device may be generated using a first subset of the ambient light values. A second light source model for the device may be generated using a second subset of the ambient light values. A current ambient light value generated by the ambient light sensor of the device may be received. The first light source model or the second light source model may be selected based on a time at which the current ambient light value was generated. Whether the current ambient light value indicates that a local artificial light source is on may be determined using the current ambient light value and selected light source model.Type: ApplicationFiled: November 8, 2021Publication date: May 26, 2022Inventors: Dongeek Shin, Shwetak Patel, Anupam Pathak

Patent number: 10709335Abstract: A method of optimizing sleep of a subject using smart-home devices may include operating a smart-home system that is configured to operate in a normal mode and a sleep mode. The method may also include determining that the smart-home system should transition into the sleep mode. The smart-home devices may use a set of default parameters when operating in the sleep mode. The method may additionally include monitoring, while in the sleep mode, a sleep cycle of the subject using the smart-home devices. The method may further include detecting behavior of the subject that indicates that the sleep cycle of the subject is being interrupted or about to be interrupted, determining an environmental control that corresponds with the behavior of the subject, and adjusting the environmental control using the smart-home devices to prevent or stop the sleep cycle of the subject from being interrupted.Type: GrantFiled: December 31, 2017Date of Patent: July 14, 2020Assignee: Google LLCInventors: Yoky Matsuoka, Shwetak Patel, Michael Dixon, William Greene

Publication number: 20200167834Abstract: Described herein are systems and methods for intelligent identification and provisioning of devices and services for a smart home. A user can identify an issue or a question with respect to how to solve a problem within their home. The system can use advanced intelligence to interact with the user to obtain information that can allow the system to identify relevant information for solving the user's problem or answering the user's question by identifying correlated information about the user, such as demographic or behavioral information, and using that information in conjunction with past purchasing information, information specific to the user's home, and the like to generate a recommendation and installation plan for one or more smart home devices for the user. Once implemented, the system can also provide confirmation that the installation was completed properly.Type: ApplicationFiled: December 28, 2018Publication date: May 28, 2020Applicant: Google LLCInventors: Yoky Matsuoka, Mark Malhotra, Shwetak Patel, Camille Dredge
