Publication number: 20230248584Abstract: Systems and methods for detecting determining a volume of urine in an absorbent article such as a diaper. A diaper loading application obtains a first measurement of ambient light received from a photodetector while a light source is off and a second measurement from the photodetector while the light source is transmitting light on an absorbent article. The application determines a normalized measurement of light reflected from an absorbent article by removing an ambient light signal from the second measurement based on the first measurement. The application determines, from the normalized measurement, a presence of urine in the absorbent article. The application further determines an estimated volume of urine in the absorbent article, wherein the determining is based on an elapsed time since the presence of urine and an activity state of an infant wearing the absorbent article.Type: ApplicationFiled: April 18, 2023Publication date: August 10, 2023Applicant: Verily Life Sciences LLCInventors: Brian Schiffer, Tushar Parlikar, Brian Ward Guilardi

Patent number: 11416538Abstract: A computing device that provides access to digital media items receives a command from an entity to share a digital media item that was uploaded by another entity. The computing device invokes an interface for trimming the digital media item in response to receiving the command. The computing device receives input for a trim operation to be performed on the digital media item. The computing device then provides a link or embed code for the digital media item for posting on a web site, wherein accessing the link or embed code causes the output of the trim operation to be presented to a user.Type: GrantFiled: April 23, 2018Date of Patent: August 16, 2022Assignee: Google LLCInventor: Tushar Parlikar

Patent number: 10264971Abstract: A system including two or more wearable devices includes at least one sensor in each device to detect signals related to the body of a wearer. User inputs, sensor outputs, or other information are used to determine an activity being performed or otherwise engaged in by the wearer and footsteps, heartbeats, discrete turns of the torso, or other events can be detected, from one or more of the sensor outputs, during a period of time that the user is engaged in the activity. A duration, amplitude, timing, mean value, or other characteristic of each such detected event can be determined, based on the sensor outputs, and used to generate a sample of clinically relevant information about the wearer. This information can then be used to determine the presence, stage, degree, progression, or other information about a disease state of the wearer or some other information about the wearer's body.Type: GrantFiled: August 29, 2016Date of Patent: April 23, 2019Assignee: Verily Life Sciences LLCInventors: Scott Brian Kennedy, Mark Murphy, Ali Shoeb, Nikhil Bikhchandani, Hongsheng Wang, Emre Demiralp, Anupam Pathak, Tushar Parlikar

Patent number: 9375160Abstract: The methods and systems for estimating cardiac output and total peripheral resistance include observing arterial blood pressure waveforms to determine intra-beat and inter-beat variability in arterial blood pressure and estimating from the variability a time constant for a lumped parameter beat-to-beat averaged Windkessel model of the arterial tree. Uncalibrated cardiac output and uncalibrated total peripheral resistance may then be calculated from the time constant. Calibrated cardiac output and calibrated total peripheral resistance may be computed using calibration data, assuming an arterial compliance that is either constant or dependent on mean arterial blood pressure. The parameters of the arterial compliance may be estimated in a least-squares manner.Type: GrantFiled: September 10, 2012Date of Patent: June 28, 2016Assignee: Massachusetts Institute of TechnologyInventors: Tushar A.
