Patent number: 11644310Abstract: Determining when a barometric-based approach for estimating an unknown altitude of a mobile device should not be used. Different approaches determine if estimating an unknown altitude of a mobile device using a measured atmospheric condition will result in an estimated altitude having acceptable or unacceptable error. If use of the measured atmospheric condition would result in acceptable error, the measured atmospheric condition is used to estimate the unknown altitude. If use of the measured atmospheric condition would result in unacceptable error, the measured atmospheric condition is not used to estimate the unknown altitude. The resultant altitude estimate is then used to locate the mobile device.Type: GrantFiled: July 9, 2018Date of Patent: May 9, 2023Assignee: NextNav, LLCInventors: Jerome Vogedes, William Alberth, Jr.

Patent number: 11624757Abstract: A platform system receives sensor data describing the state and orientation of a tracked object and models the pose of the tracked object to determine user interactions with the platform system. To ensure that incorrect sensor data due to a saturation event or connection loss does not impact user experience, the platform system identifies regions for correction in sensor data streams based on the sensor data being at or above a saturation limit or not being received. The platform system predicts sensor data for an identified region of correction by applying a fit corresponding to points adjacent to the region for correction and determining predicted sensor data using the applied fit. The predicted sensor data is used to correct the modeled pose for the tracked object.Type: GrantFiled: March 4, 2019Date of Patent: April 11, 2023Assignee: Meta Platforms, Inc.Inventors: Boyang Zhang, Joel Amado Hesch

Patent number: 11614468Abstract: A scheme for noise floor de-embedding by identifying a link or relationship between noise floor from an oscilloscope and phase jitter impact on a toggling signal. The scheme uses phase or electrical spectrum and phase detection for noise floor recognition. The scheme de-embeds the impact from random noise and also removes deterministic noise or jitter from the oscilloscope. The scheme provides accurate jitter analysis for a circuit (e.g., clock data recovery circuit) after de-embedding noise floor for the oscilloscope.Type: GrantFiled: June 25, 2020Date of Patent: March 28, 2023Assignee: Intel CorporationInventors: Liwei Zhao, Andrew Martwick, Michael W.

Patent number: 11555724Abstract: A device (1) for determining the mass flow rate of milk turbulently flowing with air in a pipe (2) in pulsed milk slugs comprises sampling a signal from a microphone (8) of the device (1) indicative of sonic signals produced by the milk flow. The sampled signals are read by a microprocessor (15) which applies a Fast Fourier Transform to the sampled signal to produce the frequency domain of the sampled signal. The microprocessor (15) is configured to compute the average energy value of the sampled signal in the frequency bandwidth of 6 kHz to 15 kHz during consecutive monitoring periods. The average energy values are inserted into a calibration equation, which may be a power law equation, a polynomial equation, a logarithmic equation or any other such suitable equation in order to convert the average energy value to a mass flow rate of the milk flowing through the pipe 2 during that predefined monitoring period.Type: GrantFiled: October 9, 2019Date of Patent: January 17, 2023Assignee: DAIRYMASTERInventors: John Gerard Daly, Edmond Patrick Harty, Christopher Kinsella

Patent number: 11468400Abstract: One or more load cells measure the weight of items at a fixture. Weight changes occur as items are picked from or placed to the fixture and may be used to determine when the item was picked or placed, quantity and so forth. Individual weights for a type of item may vary. A set of data comprising weight changes associated with interactions involving a single one of a particular type of item is gathered. These may be weight changes due to picks, places, or both. A model, such as a probability distribution, may be created that relates a particular weight of that type of item to a probability. The model may then be used to process other weight changes and attempt to determine what type of item was involved in an interaction.Type: GrantFiled: March 28, 2018Date of Patent: October 11, 2022Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Dilip Kumar, Liefeng Bo, Nikhil Chacko, Robert Crandall, Nishitkumar Ashokkumar Desai, Jayakrishnan Kumar Eledath, Gopi Prashanth Gopal, Gerard Guy Medioni, Paul Eugene Munger, Kushagra Srivastava

Patent number: 11350851Abstract: The present disclosure provides wearable apparatus and method for calculating drift-free plantar pressure parameters for gait monitoring of an individual. Most conventional techniques use different kind of sensors placed in in-sole based wearable apparatus but are costly and not effective in calculating accurate plantar pressure parameters. The disclosed wearable apparatus uses off-the shelf piezoelectric sensors that are widely available in market with less cost. The drift-free plantar pressure parameters are calculated using drift-free static pressure data obtained by numerically integrating acquired dynamic sensor data from the piezoelectric sensors, using a LiTCEM correction mechanism. A 6-DOF Inertial Measurement Unit (IMU sensor) helps in isolating zero-pressure duration indicating when a foot of the individual is in air during a stride, while obtaining the drift-free static pressure data.Type: GrantFiled: March 24, 2020Date of Patent: June 7, 2022Assignee: Tata Consultancy Services LimitedInventors: Vivek Chandel, Shivam Singhal, Avik Ghose
