摘要： An antenna assembly includes an antenna and a heatsink. The antenna may be configured to support radio communications and generate heat, and may include a forward antenna surface configured to transmit or receive communications signals and a rear antenna surface that is affixed to a substrate. The heatsink structure may be positioned to be within a forward electromagnetic field that is emitted from the forward antenna surface and away from the rear antenna surface. The heatsink structure may be configured to perform a convection operation between the antenna and a fluid to perform thermal dissipation of the heat from the antenna.

摘要： A riding lawn care vehicle (10) may include a frame (60), a steering assembly (30), a brake assembly (110), and a mechanical brake linkage assembly (120). At least a first drive wheel (32) and a second drive wheel (32) of the riding lawn care vehicle (10) may be attachable to the frame (60). The steering assembly (30) may include a first steering lever (34) and a second steering lever (34), where the first and second steering levers (34) are operably coupled to the first and second drive wheels (32) respectively to facilitate turning of the riding lawn care vehicle (10) based on drive speed control of the first and second drive wheels (32) responsive to positioning of the first and second steering levers (34) along a first direction when the first and second steering levers are in an operating position. The brake assembly may be operably coupled to the first and second drive wheels (32) to enable brakes to be selectively applied to the first and second drive wheels (32). The mechanical brake linkage assembly (120) may be configured to activate the brake assembly (110) relative to the first and second drive wheels (32) in response to movement of the first and second steering levers (34) in a direction parallel to the first direction after the first and second steering levers (34) have been moved from the operating position to a non-operating position.

摘要： A dynamic vehicle stability control system for a vehicle may include an active wing extending laterally relative to a longitudinal centerline of the vehicle and configured to be rotatable to change an angle of attack relative to wind passing over the vehicle parallel to the longitudinal centerline, a repositioning assembly operably coupling the active wing to the vehicle, and a controller operably coupled to components and/or a sensor network of the vehicle to receive status information about the vehicle. The repositioning assembly may be operated based on a wing angle command received by the controller responsive to execution of a plurality of control algorithms executed by the controller. The controller may be configured to determine the wing angle command based on respective wing angle requests generated by each of the control algorithms.
