Wall plate

A scissor apparatus for a latch assembly, which includes a spring comprising a plurality of fingers for controlling the motion one or more sliders associated with the latch assembly, and wherein the spring comprises a spring control independent of the actuation of such sliders. The fingers are generally integrated with the spring. Such a one-piece spring can be implemented as a stamped component with 2-off, 3-off or 6-off fingers to control the motion of the sliders. The stamped spring can clip onto existing latch assembly components in order to promote retention, and overcome friction with the latch assembly and return the sliders to a neutral position thereof.

Scissor mechanism for a latch assembly

Passive entry sensor systems and associated sensors are disclosed. The system sensor is locatable in the handle of a door or like structure and can provide an electromagnetic radiation beam transmitted either along the length of the handle between opposite ends thereof or between the handle and the door such that the sensor can detect at least a partial interruption of the beam by a user actuating the handle. The system can include an independent optical locking switch for actuation by a user to lock the door which locking switch comprises a shutter for intercepting the beam so as to flag the sensor. The system can include a power-up switch for actuation by a user to power-up the system, back-up switches for detecting a pull on the handle, indicators for indicating system status to the user, and backlight and ground light lighting.

Passive entry sensor system

Latch control methods and systems are disclosed, including a latch that receives power from a motor associated with a latch. A sensor can be provided for monitoring the current consumption of the motor. A microcontroller can control the latch and/or the motor, based on the current consumption data received from the sensor concerning the current consumption of the motor. Monitoring of the current waveform of the motor therefore provides speed and direction feedback data for control of the latch. Additionally, a microprocessor can process instructions for controlling the interaction of the motor, the latch, the sensor and/or the microcontroller. Such a current monitoring control system is made possible by variation in current consumption of the motor during rotation as a result of commutation, which can be interrogated by measuring the voltage drop across the motor or a shunt resistor, or through the use of other current sensors, such as, for example, a Hall-effect type current sensor.

Automotive door latch control by motor current monitoring

A keyless access sensor system for use with a keyless access control mechanism (KACM) is described for controlling the operation of a locking device. The KACM receives a signal from a sensor device for keyless access to create a first output signal before the user has begun any action on the handle in order to open the door. The first output signal is sent to a general processor, which initiates a recognition process and, after recognition of the authorized user the processor then generates an unlocking signal which unlocks the locking device before the authorized user will have fully accomplished the action of opening the door. Thus the authorized user is allowed to open the door without any specific un-ergonomic and time-consuming additional action to the simple action of actuating the handle to open the door. The second signal is generated by a device, such as a fob, card or the like, carrying a unique digital or analog identification in response to RF or IR interrogation from the general processor after it receives the output signal from the sensor device for keyless access.
