Abstract: An inverter device includes a connection device and a housing in which an inverter circuit, a switching device and a control device are accommodated. The inverter circuit is connected to a direct current (DC) circuit and to an electric machine via the connection device, and the switching device is connected to the DC circuit and to resistor via the connection device. The inverter circuit is actuated by the control device to operate the electric machine, and the switching device is actuated by the control device to selectively energize one of the resistor or the DC circuit via the inverter circuit.

Abstract: Safety system for a hand gun to prevent unauthorized use, with a blocking cartridge inserted and locked in the chamber of a hand gun, wherein upon manipulating said blocking cartridge in an internally located reaction chamber the individual components of an adhesive system are brought together, whereupon following the reaction of the components, the still-pasty adhesive system spreads and escapes through openings in the wall of the blocking cartridge and, after hardening, firmly adheres the blocking cartridge to the chamber. The blocking cartridge can be released only by an authorized institution or person equipped with a connection-releasing technology that is matched by the manufacturer to the composition of the adhesive system.
