Abstract: A method for booting an electronic device. The method includes: booting a first activation apparatus secured against tampering; and booting, with a time-defined overlap, at least one further activation apparatus secured against tampering, which is configured to activate a computer program product of the electronic device.

Abstract: A method for operating an electronic device. The method includes checking an operational software of the electronic device for an unwanted manipulation. The following steps are carried out in the event that an unwanted manipulation is detected: deactivating the operational software of the electronic device; and signaling the unwanted manipulation by way of a defined modulation of an electrical current draw of the electronic device.

Abstract: A stator for an electrical machine having a stator body which has radial stator teeth with windings. At least some of the windings are interconnected to form a circuit strand. At least two part-motors within the stator contain in each case a part of the circuit strand.

Abstract: An air pump assembly includes a pump module having an outer surface and a casing at least partially surrounding the pump module. The casing has an inner surface defining a cavity sized to snugly receive the pump module such that the outer surface of the pump module is in substantial engagement with the inner surface of the casing and is substantially prevented from moving with respect to the casing when the pump module is received within the cavity. At least one airflow passageway is defined between the inner surface of the casing and the outer surface of the pump module. The airflow passageway is configured so that air flowing through the passageway changes direction at least one time to reduce the transmission of noise from the air pump assembly.

Abstract: A device for accessing a vehicle control system via a wireless link, a gateway control unit which is connected to at least one vehicle bus and to a wireless network being provided, and the gateway control unit being freely configurable via the wireless link.

Abstract: A method for operating at least one computing device and at least one monitoring circuit (watchdog) which is allocated to the at least one computing device and which is to be controlled by the computing device according to a specific temporal pattern, in particular, for a control or safety device for a motor vehicle, the computing device being reset if the monitoring circuit fails to be controlled according to the temporal pattern. To synchronize, in as easy a manner as possible, the computing device to the monitoring circuit, subsequent to a start-up of the computing device from a reset mode into a working mode, a time base may be ascertained which elapses subsequent to the start-up of the computing device until a reset of the computing device occurs due to a failure to control the monitoring circuit according to the temporal pattern, and the monitoring circuit is controlled at time intervals that are determined as a function of the time base.

Abstract: A device for wireless transmission of a trigger signal, in particular for a restraint system, which has a redundancy path to ensure reliable triggering of a restraint system, is proposed. On a primary side of a transmitter a redundancy unit is arranged; this generates a redundancy signal from a trigger command, the redundancy signal being detected by an enable unit on the secondary side in order to enable a trigger circuit for the restraint system, the trigger circuit then being triggered by an evaluation unit on the secondary side via a trigger signal. The trigger circuit triggers a restraint system.

Abstract: A device for the wireless transmission of a tripping signal for a restraint system, a firing command from a firing bus being converted by a filter into a firing signal, which can be transmitted via an inductive or capacitative transformer. On the secondary side of the transformer, a regeneration device is arranged, which reconstitutes from the firing signal a firing command, which then is used to trigger a restraint system. The restraint system can be connected to a bus simulation, so that the driving electronics for the restraint system are the same as those which are connected directly to the firing bus.
