      Description

      Biometric immobilizer is a controlled unit protecting a motor vehicle against unauthorized use or allows the access of a motor vehicle by the rightful owner.

      US Patent No. 5,675, 490 entitled"Immobilizer For Preventing Unauthorized Starting Of A Motor Vehicle And Method For Operating The Same" discloses an immobilizer including a test unit, control devices connected through a data line to the test unit, and at least one ignition key having a transponder. When the ignition key is actuated, the test unit transmits a request signal through the data line to all of the control devices, which respond thereto by transmitting back identification codes which are compared with desired codes. The test unit prevents starting of the motor if less than a prescribed number of control devices reply with their identification code.

        Description

        This design is a major change in fire fighting ladder truck design.
        The design allows the fire fighter to ride up the ladder, saving energy. It also allows the fire fighter to send incapacitated people down the ladder alone, allowing the fire fighter to continue his/her work. This design also allows extra supplies/equipment to be sent up or down without a human being put in further danger.
        The automation for this design is critical. The ladder framework will be re-designed to deal with the special ladder.
        This design allows the ladder truck to do things a 'cherry picker' type cannot do, or cannot do without serious uses of energy and manpower.
