Abstract: An inverter for an electric machine. The inverter has at least one semiconductor switch half-bridge. The inverter also has a current sensor, which is designed to detect a phase current generated by the at least one semiconductor switch half-bridge, depending on a magnetic field generated by the phase current. The inverter has a voltage source for supplying power to the current sensor. The voltage source is designed to supply the current sensor, in particular in a referenced manner, with an in particular constant supply voltage relative to the, in particular pulse-width-modulated, phase potential of the semiconductor switch half-bridge.

Abstract: A method for pressure-independent temperature determination using a metal diaphragm is provided. A bridge circuit having multiple resistors is provided on this diaphragm. One pair of resistors is near the center of the diaphragm and another pair of resistors is situated at a distance from the center. The resistors are provided on the metal diaphragm in such a way that the tensile elongation of the pair of resistors near the center corresponds in absolute value to compressions of the pair of resistors far from the center.

Abstract: A handheld, portable, motorized clamping device is disclosed. The device includes a housing, a frame, a stationary clamp member, and a displaceable clamp member. The displaceable clamp member may be repositioned by a drive assembly, or may be manually adjusted. In another embodiment of the invention, the stationary clamp member may be repositioned on the frame to alter the dimensions of the clamp opening. In still another embodiment, the clamp device operatively connects to a secondary tool that engages the drive assembly.
