Publication number: 20240195798Abstract: In one embodiment, a method, by an authentication server, includes generating a transaction identifier associated with an authentication request received from an external device. In response to verifying a first authentication factor of the authentication request, the method includes transmitting a prompt and the transaction identifier to the external device, wherein the prompt is an HTTP link associated with a browser comprising a generated cookie, the generated cookie being associated with the transaction identifier. The method includes receiving a signal comprising a transmitted transaction identifier and an instruction to process the HTTP link. The method includes instructing an application installed on the external device to open the browser in a webview in response to processing the instruction, wherein a cookie is provided. The method includes identifying the generated cookie based on verifying the transmitted transaction identifier.Type: ApplicationFiled: December 13, 2022Publication date: June 13, 2024Inventors: Harold Todd Chapman, Robert Jacob Linial Small, Michael G. Brown, Adam Vincent Patruno, Dylan Miles Kite, Zachary Oliver Weglarz, Erdenebat Gantumur

Patent number: 10458344Abstract: A method of filtering a targeted frequency from a pedal input signal is provided. The method includes the steps of sampling the pedal input signal at a sampling frequency, calculating a moving average of the pedal input signal from samples of the pedal input signal, and outputting a filtered signal based on the moving average. A throttle filter system is also provided. The system includes a pedal configured to be actuated to set a desired acceleration of a vehicle, a position sensor configured to convert a position of the pedal into an electrical signal, a vehicle driveline configured to accelerate the vehicle, and a filtering module configured to accept the electrical signal from the position sensor and to filter the electrical signal to remove oscillations at a targeted frequency. In the system, the driveline accelerates the vehicle based on the filtered electrical signal.Type: GrantFiled: October 18, 2017Date of Patent: October 29, 2019Assignee: Spartan Motors, Inc.Inventors: Joshua J. Ryan, Patrick McGraw, Johann Eloff, Murali X. Balasundrum, Todd Chapman

Patent number: 6393022Abstract: A method and apparatus are provided for processing Integrated Services Digital Network User Part (ISUP) signaling within a switching system. ISUP signaling messages associated with a plurality of ISL trunks are processed within a switching system by provisioning the ISL trunks, identifying the ISUP signaling messages that are associated with the ISL trunks, and routing the identified ISUP signaling messages within the switching system to the far endpoints of the trunks using layers 1, 2, and 3 of Open System Interconnection (OSI) protocol.Type: GrantFiled: November 19, 1997Date of Patent: May 21, 2002Assignee: Nortel Networks LimitedInventors: Jeffrey Allen Hewett, Keven Todd Chapman
