Publication number: 20250068865Abstract: Embodiments of the present disclosure include improvements to millimeter wave backscatter RFID technology for rotational sensing. Embodiments of the present disclosure leverage the polarization mismatch of linearly polarized antennas to capture rotational motion with high accuracy. One embodiment described herein includes utilization of a four-antenna system, each featuring a different modulation frequency. This configuration allows for independent extraction of rotational information by observing the changes in signal amplitudes as the angle of rotation varies. With a polarization offset of 15° between successive antennas, the backscatter channels trace distinct curves, enabling the resolution of angular ambiguities.Type: ApplicationFiled: August 26, 2024Publication date: February 27, 2025Inventors: Ajibayo Adeyeye, Jimmy Georges Donald Hester, Charles A.

Publication number: 20240168149Abstract: Techniques and apparatuses are described that implement localization and health monitoring. With the use of multiple backscatter tags, a reader can be implemented with a single antenna and have a relatively small footprint compared to other systems that utilize antenna arrays or multiple readers. Also, the backscatter tags can be implemented as passive devices and located at fixed positions. In this way, a single power source can be provided at the reader, and target angular resolutions can be realized without the additional mechanical complexities associated with other moving systems. Additionally, the backscatter tags can be implemented using relatively low-cost commercial off-the-shelf hardware. As such, performance of the reader can be readily customized with the purchase of additional backscatter tags.Type: ApplicationFiled: March 30, 2021Publication date: May 23, 2024Applicant: Google LLCInventors: Aline Eid, Jiang Zhu, Luzhou Xu, Jimmy Georges Donald Hester

Patent number: 11146832Abstract: This disclosure describes techniques for distributed storage of files that represent video content across different storage tiers to reduce the amount of computing resources used to store the files, while maintaining a low latency when responding to user requests to stream the video content. Video streaming services support the streaming of video content at different resolutions to support various user devices and/or user preferences. To provide streaming of a particular video content item at different resolutions, the video streaming services may store multiple files that represent the video content item for the different resolutions and stream at different bitrates to user devices. The techniques described herein include storing files configured to stream a video content item at different bitrates (and for different display resolutions) in a tiered storage structure to reduce the amount of computing resources taken to store the files.Type: GrantFiled: November 8, 2018Date of Patent: October 12, 2021Assignee: Amazon Technologies, Inc.Inventors: Ryan Farris, Jimmy George, Jesse Robert Hepburn, Benjamin Schwartz, Mark DeSpain, Mathew P.

Patent number: 9690832Abstract: A method of refreshing a materialized view includes creating a materialized view based on a first result of a database query executed against a set of tables stored in a database and discovering a set of child storage objects associated with a parent storage object. The method also includes inserting, based on discovering the set of child storage objects, an entry into one or more tables of the set of tables, the entry including a child storage object of the set of child storage objects. The method further includes delaying a refresh of the materialized view until after the entry is inserted into the set of tables and then refreshing the materialized view, which is based on a second result of the database query executed against the set of tables.Type: GrantFiled: October 6, 2014Date of Patent: June 27, 2017Assignee: NETAPP, INC.Inventors: Jimmy George, Rajath Ranganath

Patent number: 4744144Abstract: A hand held, oscillating razor for wet shaving which comprises an internally operated eccentric for forcibly, rapidly vibrating the cutting blades. Preferably the razor comprises an elongated, generally tubular housing adapted to receive a carriage which mechanically secures a rotatable eccentric, a motor for rotating the eccentric, and an associated angularly tilted battery which powers the motor. A receptacle integrally associated with the neck of the housing is adapted to removably receive a standard blade cartridge for shaving. The razor exhibits a characteristic resonant frequency, and its center of mass lies apart from its central axis, so that the razor characteristically displays a dynamic couple in operation. The motor rotates within a speed range of between 1.414 and two times the natural resonant frequency of the razor so as effectuate as comfortable a shave as possible. Within this range razor shaving characteristics are substantially unaffected by the mode or manner in which the unit is held.Type: GrantFiled: April 2, 1986Date of Patent: May 17, 1988Assignee: Wellington Investments, Inc.Inventors: Charles M.
