Patent number: 11929645Abstract: A direct drive drive actuator includes a base structure and a driven structure that is journally supported and translatable relative to the base structure. The driven structure is disposed in a fixed spatial relationship to the base structure. A plurality of first pole arrays is disposed on the driven structure. A plurality of second pole arrays, corresponding in number to the plurality of first pole arrays is disposed on the base structure. An electrical power source is provided. A controller is coupled to the power source and the first plurality of pole arrays and the second plurality of pole arrays, wherein the controller is configured to selectively electrically energized windings of the first plurality of pole arrays and the second plurality of pole arrays such that an electro-magnetic force is formed between poles of the first plurality of pole arrays and poles of the second plurality of pole arrays.Type: GrantFiled: December 17, 2021Date of Patent: March 12, 2024Assignee: GENERAL DYNAMICS LAND SYSTEMS—CANADA CORPORATIONInventor: Mark Gojkovic

Patent number: 11387917Abstract: A wireless slip ring, system and method for transmission of data across a rotatable junction can be provided to permit transmission of data from a fixed element to a rotating element across a rotary interface. The wireless slip ring can provide high bandwidth multi-channel data transmission, for example each channel can have a bandwidth greater than 1 gigabit per second. Each channel may include a plurality of input/output data streams that can be serialized by a digital electronic circuit for transmission across the slip ring and then deserialized into its respective data streams. The wireless slip ring can form an annular chamber to act as a wave guide for the wireless signal for providing a continuous conductive covering around the annular chamber to act as a faraday shield to contain radio frequency emissions and prevent external jamming.Type: GrantFiled: November 4, 2019Date of Patent: July 12, 2022Assignee: General Dynamics Land Systems—Canada CorporationInventors: Herb Peyerl, Andrew Hookey, Terry Chepyha
