Patent number: 11888837Abstract: Techniques are described for client registration for authorizing an aggregator service to access data on behalf of an application, through self-registration of an application client identifier and issuance of authorization token(s) based on the application client identifier. Implementations provide a technique for dynamic client registration that avoids the need for manual vetting and manual generation of the client credential grant. Additionally, the implementations described herein enforce domain values around the scope and/or purpose of the client grant. This allows for support of application providers through a single point of registration that supports multi-layer and channel. This also allows for support of a scalable authorization solution for any suitable number of clients. The dynamic client registration process adds an additional layer of security through the OAuth client grant and mutual authentication.Type: GrantFiled: June 24, 2021Date of Patent: January 30, 2024Assignee: United Services Automobile Association (USAA)Inventors: Alejandro Vera, Miguel Solís, Jr., Hieu Nguyen, Jason Paul Hendry, Nathan Mahoney, Debra Randall Casillas

Patent number: 11648886Abstract: An electrically-powered accessory for vehicles includes a vehicle structure. A connector mechanically connects an electrically-powered accessory to vehicle structure. The connector includes a movable lock member that mechanically locks the electrically-powered accessory to the vehicle structure when the movable lock member is in a locked position. The movable lock member causes the electrically-powered accessory to be electrically connected to an electrical power supply of the vehicle when the movable lock member is in the locked position, and electrically disconnects the electrically-powered accessory from the vehicle power supply when the movable lock member is in the unlocked position.Type: GrantFiled: September 2, 2021Date of Patent: May 16, 2023Assignee: Ford Global Technologies, LLCInventors: Fernando Alfonso Oros Cisneros, Antonio Espíritu Santo, Jacobo Alejandro Vera Gómez

Publication number: 20220115889Abstract: A battery charger includes a battery power regulator configured to set a charge signal provided to a battery based on a charge control signal and charge enable signal. The battery charger also includes a controller configured to provide the charge control signal to the battery power regulator. The controller is also configured to temporarily de-assert the charge enable signal for a predetermined amount of time in response to determining that a change is needed in the charge control signal. The controller is further configured to re-assert the charge enable signal after the predetermined amount of time.Type: ApplicationFiled: December 21, 2021Publication date: April 14, 2022Inventors: Mustapha El Markhi, Alejandro Vera, Rohit Bhan

Patent number: 7926360Abstract: Methods and apparatus enable measuring flow of a fluid within a conduit. For example, flowmeters may measure the velocity of production fluid flowing through production pipe of an oil/gas well. The flowmeters rely on detection of pressure variations generated as a result of a backward-facing step as a basis for flow measurement calculations. Pressure sensing occurs away from the step in a direction of the flow of the fluid in an enhanced turbulence region of the flowmeter where the inner diameter remains enlarged as a result of the step.Type: GrantFiled: October 5, 2009Date of Patent: April 19, 2011Assignee: Weatherford/Lamb, Inc.Inventors: Omer Haldun Unalmis, Espen S.
