Voice activation using a laser listener

A voice activation system for a vehicle comprising:

• a vehicle which includes a plurality of window panels each having an outside surface exposed to the exterior of the vehicle and an inside surface exposed to an interior of a passenger compartment of the vehicle;
• a plurality of laser listening devices located in the interior of the passenger compartment, wherein in each one of the plurality of laser listening devices is operatively positioned relative to the interior surface of a respective one of the plurality of window panels so that the each one of the plurality of laser listening devices can project a laser beam onto the inside surface of the respective one of the plurality of window panels so that the plurality of laser listening device use the laser beam to detect vibrations from a user's voice that are reverberated to the inside surface where the respective one of the plurality of laser listening devices generate a laser listening signal indicative of the vibrations detected by the respective one of the plurality of laser listening devices, wherein the plurality of laser listening devices further include a photo sensor for detecting the movement of the respective one of the plurality of window panels by detecting the reflection of the laser beam off the at least one sound panel;
• and
• a controller for receiving the laser listening signal from each of the plurality of laser listening devices and determining the presence of a pre-identified command of the user and operating an action in the vehicle in response thereto.

A voice activation system for a vehicle comprising:

• a vehicle which includes at least one sound panel capable of reverberating vibrations of a user's voice from the outside of the vehicle;
• a laser listening device mounted to the vehicle and producing a laser beam that is projected onto the at least one sound panel, said laser listening device uses the laser beam to detect vibrations from a user's voice that are reverberated by the at least one panel and generating a laser listening signal indicative of the vibrations detected by the laser listening device;
• a controller for receiving the laser listening signal and determining the presence of a pre-identified command of the user and operating an action in the vehicle in response thereto;
• and
• a microphone mounted to the exterior of the vehicle, configured to detect sound from the outside of the vehicle and generate a listening signal to the controller, wherein the controller receives both the microphone listening signal and the laser listening signal and performs a comparison to filter out ambient noise from outside the vehicle.
