  • Publication number: 20020157436
    Abstract: An external actuating mechanism for vehicle doors in doors, hoods, lids or the like, wherein the mechanism includes a handle for opening the door, a locking unit for activating and deactivating the lock, and at least one electrical light source for temporarily illuminating a field of operation of the mechanism. An electrically operated sensor is mounted in the interior of the handle and is connected to the current supply of the vehicle. When an authorized person who is in the possession of a data carrier approaches, the sensor releases a data communication with the data carrier and deactivates the lock after a successful data comparison. A bore in the handle serves as housing for receiving the light source. The light source is connected to the electrical supply lines of the sensor arranged in the interior of the handle. The electronic system of the sensor serves for switching on the light source.

Rotation of the handle extends or retracts a bolt that closes or opens the lock. The keypad includes indicia that give the user visual cues as to the orientation of the handle, thereby informing the user of the extended or retracted condition of the bolt. A battery pack is used to energize circuitry that recognizes a code entered through the keypad. The circuitry provides a control signal that activates a solenoid to extend or retract a bolt blocking device, which in turn prevents or enables movement of the bolt. A visual indicator warns of a low voltage or power condition in the battery pack. Electrical contacts are provided in the face plate of the handle to connect the circuitry to an external power source in case the battery pack fails.

  • Patent number: 6297725
    Abstract: A keyless locking mechanism is activated by a remote unit which transmits coded signals to an electromechanical door lock device. The electromechanical device components are configured for secure mounting within the void or hollow portions of existing door locking apparatus. A sensor in the outer doorknob receives and forwards the coded signals to a processor which compares them with a predetermined stored signal. If an acceptable comparison is made, the processor generates control signals for the device, which acts solely along the locking axis to enable or disable the door locking assembly. The coded signals include two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver.

  • Patent number: 6181025
    Abstract: An integrated, flexible interrogator-coil circuit provides security for the type of lock opened by a key that transmits a coded signal to an interrogator circuit associated with the lock. When the key is inserted into the lock, a coil in the key is brought into proximity with an energized coil associated with the lock. The resulting current induced in the key's coil causes the key to transmit the coded signal. If the coded signal is recognized by the lock's interrogator circuit, the key opens the lock. The lock coil is an etched metallic spiral on a loop portion of the circuit board and the interrogator circuit components are mounted on a base portion of the circuit board on which is etched a metallic circuit pattern. The integrated interrogator-coil circuit is faster and more economical to manufacture. Because the circuit is on a flexible circuit board, it can be made a part of the lock assembly itself, thus facilitating use of this type of security system.

  • Patent number: 6178791
    Abstract: The technique for electronically resetting a magnetically sealed solenoid to an unattracted, unactuated position is described for use with solenoids which have either a residual magnetic or a permanent magnet holding force necessary to retain the armature of the solenoid in its actuated position until such time as the armature is either physically displaced by a mechanical force or an electronic signal is applied to the solenoid. This displacement creates a reverse polarity magnetic field, effectively overcoming the magnetic field acting to hold the armature in its actuated position, permitting a small mechanical force to reset the armature. In order to prevent a lock or similar device from being conditioned for opening and possibly left in that condition for a significant period of time while unattended, jeopardizing the security of the container and its contents, the actuation of the armature in the reset or release phase may occur a relatively short time following its actuation.
