  • Publication number: 20240425018
    Abstract: A ground-engaging support structure for rotating a vehicle-carrying platform supported thereby such that a vehicle driven onto the platform is rotatable about a rotational axis extending substantially perpendicularly to the ground, the structure including: a base for carrying and rotating the vehicle-carrying platform; and one or more ground-engaging mechanisms adjustably secured to and extending outwardly from the base for facilitating load distribution of the platform and vehicle thereon such that the support structure is operable on uneven or sloped ground.

  • Publication number: 20240195798
    Abstract: 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.

  • Patent number: 10458344
    Abstract: 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.

  • Patent number: 8517357
    Abstract: A gas spring and damper assembly includes a damper and a gas spring. The damper includes a damper housing and a damper rod. The gas spring includes a first end member, a second end member and a flexible wall operatively connected therebetween. A friction-reducing element is operatively connected between the damper housing and the second end member. A sealing element is operatively disposed between the damper housing and the second end member such that a substantially fluid-tight seal is formed therebetween.

  • Patent number: 6393022
    Abstract: 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.
