Abstract: A two-phase cooling system for an X-ray high-voltage generator comprises a heat sink block and a heat sink. The heat sink block spatially surrounds a cooling duct loop, wherein the cooling duct loop is at least partially filled with a working medium and is configured to act as an oscillating heat pipe. The heat sink is configured to dissipate heat from a heat source. The heat sink block includes a material including a polymer.

Abstract: Systems and methods for controlling aerial vehicles are provided. An aerial vehicle includes a single circuit board with a number of processor devices and a memory including instructions to perform autonomy operations. The autonomy operations include obtaining GNSS data from GNSS assemblies electrically connected to the processor devices, APNT data from APNT assemblies electrically connected to the processor devices, and radar data from the radar assemblies electrically connected to the processor devices. Each of the assemblies are disposed on the same circuit board that includes the number of processor devices. The processor devices determine a vehicle location based on the GNSS data, the APNT data, and the radar data, identify airborne objects based on the radar data, generate a motion plan based on the vehicle location and the identified objects, and initiate a motion of the aerial vehicle based on the vehicle location.

Abstract: A method for positioning a welding head or welding torch of a robot welding system over a workpiece sends microwaves as a measuring signal from a transmitter arranged on the welding head to the workpiece. The microwaves reflected on the workpiece are received by at least one receiver arranged on the welding head, and the received microwaves are evaluated by an evaluation module for determining the position of a workpiece edge. The microwaves are sent from at least one transmitter in different positions on the welding head, and the reflected microwaves are received, with a change of polarization, by the at least one receiver, having a polarization plane arranged at an angle to the polarization plane of the transmitter. The position of the edge is determined by the evaluation module at least on the basis of a phase change of the respective microwaves reflected on the different positions.
