Publication number: 20240084827Abstract: A piston assembly for use in a gas spring or damper can include a piston rod partially positioned within a pressure tube, and a linear position sensing apparatus capable of tracking and determining the velocity of the piston rod. The linear position sensing apparatus can include a sensor, such as a waveguide sensor, connected to the piston rod such that the sensor moves with the piston rod. A beacon, such as a magnet, can be contained within the pressure tube and the sensor can detect the position of the beacon relative to the sensor.Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Applicant: Stabilus GmbHInventors: JAMES T.

Publication number: 20230358289Abstract: A damping apparatus for use with a solar panel array and a solar tracking device that is operatively connected to the solar panel array to control positioning of solar panels. The damping apparatus can absorb kinetic energy from movement of the solar panels and convert the kinetic energy to heat energy. The damping apparatus can include one or more sensors that measure collect data corresponding to the heat energy. The damping apparatus can send instructions to the solar tracking device for adjusting the position of the solar panels based on the analysis of the sensor data.Type: ApplicationFiled: April 16, 2023Publication date: November 9, 2023Applicant: Stabilus GmbHInventors: JAMES T.

Patent number: 7993070Abstract: A coupling member for pivotally coupling an end of a device to a mounting ball includes a body connectable to an end of the device and defines a socket for receiving a mounting ball. The body further includes slots communicating with the socket. A sliding element arranged in a longitudinal groove of the body is movable from a first position to a second position. A C-shaped spring has two ends and a center section, the ends being received through the slots and projecting into the socket for holding the mounting ball in the socket. The sliding element interacts with the center section of the spring when the sliding element is moved to the second position so that the ends of the spring are drawn out from the socket to release the mounting ball from the socket, whereby the mounting ball is releasable from the socket without external tools.Type: GrantFiled: August 20, 2008Date of Patent: August 9, 2011Assignee: Stabilus GmbHInventors: James T. Kull, Brian M. Waypa, Joshua S. McNair, Rodney A. Armstrong
