摘要:
An arrangement for identifying a movable object includes a transponder disposed on the movable object and including an electrical memory that can be read out in a wireless manner by an electrical interrogating device which is disposes in proximity of the object. A sensor arrangement is disposed on the object and electrically linked to the transponder for writing a read-out-capable status information into the memory in response to irregular or unauthorized use of the object.

In a failsafe method and apparatus for signalling theft for a motor vehicle, an item of theft-signalling information is produced as a function of the signal state of at least one of a plurality of monitoring signals, which are indicative of vehicle states. According to the invention, the theft-signalling information is produced only if the signal states of a plurality of monitoring signals are present in one of one or more prescribed theft-signalling combinations. Each theft-signalling combination comprises one or more signalling conditions, which succeed one another in a specific time sequence and which signalling conditions themselves comprise one or more theft indicative combinations of jointly interrogated signal states of associated monitoring signals.

In a process for marking industrial products or parts, a plurality of spot welds serve as carriers of characterizing information, especially in encoded information. Information is encoded in said spot welds by varying the position of each weld relative to a reference position.

A process and an arrangement for shutting down a vehicle by means of a shut-down signal is the result of a shut-down request. During a vehicle-side analysis, a conclusion is drawn from a current vehicle operating condition and/or a current vehicle location according to defined criteria regarding a shut-down site which is safe with respect to traffic and/or a traffic-safe shut-down site is recognized, in which case the shut-down signal is not generated before the current vehicle operating condition represents a traffic-safe shut-down site and/or before the current vehicle location corresponds to a traffic-safe shut-down site.
摘要:
A process and device for controlling a motor vehicle central locking system that has multiple station operation from the driver's door and from the trunk lid. A central locking of the door locks of the motor vehicle is avoided when mechanically securing the lock of the trunk lid against opening from the outside without a key in the unlocked state. This is done by switch-controlled suppression of the effect of the locking control signal normally generated when locking.

An anti-theft device for a car radio having a theft module, which renders the car radio inoperative when the radio is slid out of its installation recess in the vehicle, is provided by a joint housing for a power supply and anti-theft protection plug connection elements, as well as for a change-over switch controlling the theft module. The housing is fastened via the plug connection elements at the rear wall of the car radio such that the change-over switch is inevitably actuated by the frame of the installation recess during the sliding-out of the radio.

An alarm system having improved acoustic signal transmitting capability is provided for motor vehicles. The radio speaker system of the vehicle is employed for both passenger listening and for warning signal transmission in the event of unauthorized intrusion or attempted theft. The speakers occupy their usual installation positions in a vehicle, such as horizontally mounted in the dashboard, when used for the purpose of listening to a radio or tape. When the vehicle is unoccupied, and theft or tampering are attempted, an alarm system is activated which causes a control element to swivel the speaker into a position parallel to an external surface of the vehicle. Due to this repositioning of the speaker, reflection of an alarm signal back into the interior of the vehicle is minimized, and transmission of the alarm signal to the outside of the vehicle is optimized.
摘要:
A theft protection system for an installation unit recessed in an installation passage protects the installation unit mechanically and by an electrically initiated alarm by permitting the installation to be pulled out of the installation passage to a distance limited mechanically by a movable protection stop and by actuating an electrical theft protection contact within this distance by utilizing the relative motion between the installation unit as an installation retention arrangement and the installation passage to initiate the alarm.
摘要:
A control arrangement for a combined central locking and burglar alarm system for motor vehicles is constructed in such a manner that an accidentally tripped false alarm can be deactivated in a single manner by a designated key and a key detection switch associated with a door locking cylinder, so that the activation state of the burglar alarm system is automatically adapted to the existing locking state of the central locking system.
摘要:
An anti-theft arrangement for a sound-reproducing apparatus, such as a radio, installed into a mounting compartment of a motor vehicle whose contact arrangement assures a high functioning reliability both during the driving operation as well as during service and installation operation as also during unauthorized removal of the apparatus.
