Abstract: A lift device and a method of controlling the lift device are provided. The lift device has a lifting mechanism supporting a lifting platform relative to the chassis. An electric motor is drivingly coupled to a traction device, and a traction battery is in electrical communication with the electric motor. A user input is provided to control a speed of the lift device by inputting a requested speed. A controller is configured to, in response to the lift device being on a non-zero grade and if the requested speed is greater than a predetermined speed, command the electric motor to output a braking torque and provide electrical power to the traction battery, and limit the speed of the lift device to the predetermined speed.

Abstract: The present invention relates to a transition arrangement (1) between a SIW and a waveguide interface (3). The SIW comprises a dielectric material (4), a first and second metal layer (5, 6) and a first and second electric wall element (7a, 7b) running essentially parallel and electrically connecting the metal layers (5, 6). The transition arrangement (1) comprises a coupling aperture (8) in the first metal layer (5) and a third wall element (7c) running between the first and second electric wall elements (7a, 7b). The transition arrangement (1) further comprises an intermediate transition element (9) with a first and second main surface (10, 11), and a transition aperture (12) having first and second opening (13, 14) with corresponding first and second widths (w1, w2).

Abstract: An antenna arrangement comprising a SIW with at least one radiating arrangement. The SIW comprises a dielectric material, a first and second metal layer and a first and second electric wall element running essentially parallel and electrically connecting the metal layers. For each radiating arrangement, the antenna arrangement comprises at least one coupling aperture in the first metal layer, and for each coupling aperture there is a third wall element running between the first and second electric wall elements, across a SIW longitudinal extension (es). For each radiating arrangement, the antenna arrangement further comprises an at least partly electrically conducting antenna component which comprises at least four radiating elements and is surface-mounted on the first metal layer, enclosing at least one coupling aperture. For each radiating arrangement, electromagnetic signals are arranged to be transmitted between said coupling aperture and said radiating elements.
