Abstract: A device for connecting a first network comprising a first energy storage element and a second network comprising a second energy storage element includes switching circuitry and pre-charging circuitry. The switching circuitry is configured to electrically couple the first network and the second network. The switching circuitry comprises a first switching element configured to bi-directionally allow current between the first network and a center point node when operating in a closed state. The switching circuitry further comprises a second switching element configured to bi-directionally allow current between the second network and the center point node when operating in a closed state. The pre-charging circuitry is configured to limit current to the center point node when a first voltage at the first energy storage element equalizes with a second voltage at the second energy storage element.

Abstract: Embodiments relate to machines including a movable part. A transmitter circuit is configured to generate a radio signal and to transmit the radio signal towards the movable part via a transmit waveguide. A reflection of the radio signal from the movable part is received by a receive waveguide and guided through the receive waveguide to a receiver circuit, which is configured to determine a position and/or a speed of the movable part based on at least the received radio signal. The transmitter circuit and the receiver circuit may be comprised by a radar sensor.
