A security configuration in or for a motor vehicle, which includes a bodywork part, such as a door, and a window pane arranged in the bodywork part. The security configuration includes a touch-sensitive keypad integrated in or mounted to the window pane. The keypad has a plurality of touch sensors, each of which takes the form of resonant oscillating circuits and via which an actuation of a respective touch sensor can be picked up. An electronic evaluation system is configured for the purpose of detecting an actuation of the keypad and attributing said actuation to a respectively actuated touch sensor. There is also provided a motor vehicle which includes such a security configuration.

A device for attaching a steering wheel hub to a steering wheel column, while simultaneously fixing a contact unit to the steering wheel, includes a fastener that has a head part engaging in the hub and a shank that engages partially in the hub and partially in the shaft. In a locked position, the fastener engages a recess in the contact unit to prevent the steering wheel hub from rotating relative to the stator of the contact unit. In an unlocked position, the fastener partially engages the hub, partially engages the column, and disengages from the recess in the contact unit to fixedly connect the hub to the column and allow the hub, and therefore the rotor of the contact unit, to rotate.

An ignition circuit output stage which is driven by one or several microprocessors. Up to now different modes of operation each required their own different ignition circuit output stage. The ignition circuit output stage according to the invention is programmable - that is, using one and the same output stage, different modes of operation can be selected such as, for example, the unregulated or output stage mode as well as the regulated and limited output current mode. The circuit essentially consists of a down converter which, when activated, will regulate and limit the discharge current. The down converter can be activated and deactivated by means of an appropriate signal. When the down converter is in its deactivated state, an unregulated discharge takes place; this is the output stage mode. With the programmable output stage it is possible to select the best mode of operation for the relevant application case--such as, for example, operation without inductance as well as energy supplied directly from the onboard battery--without different output stage ICs being required.

An ultrasonic monitoring system for the interior of a motor vehicle having two mutually spatially separately secured emission elements (S1, S2), the main lobes of the directional characteristics of which are oriented in different directions, and having at least one reception element (E1, E2), but at as a rule having at least two mutually physically separate reception elements (E1, E2). The reception elements (E1, E2) are not formed by the emission elements (S1, S2), but are physically separate from all emission elements (S1, S2). The two emission elements (S1, S2) are operated alternately with pauses in such a manner that in each instance firstly only one of the emission elements (e.g. S1) emits an ultrasonic pulse, which is thereafter received by the reception element (E1 ) associated with this emission element (S1), and only after such reception does the other emission element (S2) emit ultrasound, which is thereafter received by the reception element (E2) associated with this emission element (S2 ). The main lobes of the directional characteristics of the emission elements (S1, S2) and reception elements (E1, E2) are oriented so that each reception element (E1, E2) receives particularly clearly those emission signals of the emission element (S1, S2) associated with it (E1, E2) which propagate by repeated reflections in each instance via a plurality of panes (VS1/VS2, HS1/HS2) in the V interior of the motor vehicle.

A boring tool for producing undercuts in preformed holes. The boring tool has a cutting element which is provided at one end of a driving shaft. In order to produce the undercut, the driving shaft can be deflected at right angles to the axis thereof via a deflection mechanism. The deflection mechanism is accommodated in the boring tool, and is provided with a longitudinally displaceable deflection rod for positively deflecting the driving shaft. In the deflected position, the driving shaft is driven by a rotary drive which is separate from the turning drive. As a result, the undercuts can be very precisely produced.
