  • Patent number: 7224266
    Abstract: A method to identify a person driving a vehicle and his/hers driving style, and also to switch on the vehicle either to a driving-allowing mode or to a drive-stop mode, is provided. In the method, the vehicle includes a scanner, and the driver is provided with a data-containing card or object. According to the method, the driving style information of the driver is stored on the card or object, and on starting driving the driver inserts the card or object into the vehicle scanner. Thereafter, data received from selected vehicle controls and/or data from varying information-collecting detectors is compared with information stored on the driver's driving style card, and on basis of the comparison the control unit in the vehicle either allows driving or enters a drive-stop mode.

  • Patent number: 7196432
    Abstract: In the device a controllable switch is built into the control device which enables the start authorization and by means of which the supply voltage with which this controllable switch is supplied can be switched off. To check a start authorization a diagnosis can be undertaken which is realized with known resistance elements in the voltage supply line between identification device holder and control device. This allows the voltage drops across the elements to be compared with the corresponding required values. Simple short circuiting of the starter or the ignition is thus no longer possible since this would be detected by the control device as a result of the changes in voltage drop. In addition a fault in the supply voltage or the feed lines can be definitively detected.

  • Patent number: 7183903
    Abstract: A security locker is for securing articles externally on a vehicle. The locker comprises a locker having at least one opening facing the exterior of the vehicle when the locker is fitted thereto, wherein the opening provides access to the interior of the locker. A door is moveable between an open position in which the interior of the locker is accessible through the opening from outside of the vehicle when the locker is fitted thereto, and a closed position in which the locker is inaccessible. The locker includes locking device that, when activated, locks the door in a closed position to prevent unauthorized access to the locker, and when deactivated unlocks the door to enable access to the locker. An input device is operatively connected to the locking device, wherein the locking device is accessible from outside the locked vehicle and it deactivates the locking device when an identifiable code is entered to thereby allow keyless entry to the locker.

  • Patent number: 7129816
    Abstract: Provided is a remote control system capable of preventing a key code from being deciphered when the key code is transmitted from a transmitter to a receiver to be registered. In the transmitter, in response to a specified switch operation, a k-th common key code in a table to be used for enciphering a key code is changed to a registration key code stored in advance so that a key code is enciphered through the use of the table including the registration key code. A transmission code is produced by adding a predetermined code to the enciphered key code and the transmission code signal is transmitted to the receiver. This prevents easy deciphering of the key code because the key code is transmitted in a state enciphered.

    Abstract: An antitheft device for a motor vehicle has a first receiver (2) in the motor vehicle, which is designed to receive signals in narrowband. The signals received by this receiver are evaluated in accordance with the code information contained in them. Furthermore, the antitheft device has a second broadband receiver (7) which receives signals outside the useful frequency band (3). If signals are received whose signal strength is above a threshold value (S), whose signal duration is shorter than a predefined time period (t2–t1) or whose code information corresponds largely to anticipated code information, the access to the motor vehicle, and its use, are not enabled.

  • Patent number: 6980105
    Abstract: In an integrated system of alarm components used in the real estate industry, the product family consists of three primary components: a portable transmitter unit, a vehicle-mounted transceiver unit, and a house-installed receiver unit. The system is intended to enhance the personal safety of real estate professionals who venture into the field, e.g., to show vacant houses to potential buyers. The transmitter is sized to be handheld, attached with a belt clip, or carried in pocket. When a panic button on the transmitter is depressed, the transmitter sends coded radio frequency signals which will activate either or both of the vehicle-mounted transceiver and the house-installed receiver as well as other system devices within range. When the transceiver is activated, the unit's horn will sound, and the transceiver will in turn transmit a coded radio frequency signal to any one or more identified receiver units sharing the same signal code.
