  • Patent number: 7180414
    Abstract: A method of monitoring movements of an individual or object provided with a direction indicator that is adapted to send to a monitoring center from a mechanical or electronic sensor a signal that discloses the direction of the direction indicator so as to enable, together with other signals sent to the monitoring center and disclosing the position of the individual object, which is shown on a display screen in the form of a correctly-turned three-dimensional animated picture. The direction indicator includes an indicating element which is adapted to take essentially the same position regardless of the orientation of the direction indicator. The direction indicator includes sensors for sensing the position of the indicating element and producing a signal that can be sent to a monitoring unit which shows the direction of the individual or object carrying the direction indicator.

  • Patent number: 5563453
    Abstract: A method and apparatus for remotely controlling one or more vehicle functions. The method includes providing a first coded signal transmitted by a cordless transmitter. The signal is received in a receiver located in the vehicle. The receiver includes a decoding device to detect and identify the code and to compare the signal code with a vehicle specific code. When agreement is found between the received code and the vehicle specific code, the receiver activates one or more electronic circuits in the vehicle through the agency of a control circuit, such as to deactivate one or more of the vehicle functions. The method also includes transmitting from the cordless transmitter a second coded signal which results in the activation of those vehicle functions that were earlier deactivated.
