DISCLOSURE OF INVENTION
An object of the present invention is to provide an improved system for displaying an area outside a normal viewing area to a vehicle driver.
In carrying out the above object and other objects of the present invention, a system is provided for displaying an area outside a normal viewing area to a vehicle driver. The system includes a self-powered, mobile camera unit including a camera for generating images of objects, a camera control unit for controlling the camera, a camera transceiver unit coupled to the camera control unit for wirelessly transmitting the images and a first plurality of docking connectors coupled to the camera control unit. The system also includes a vehicle transceiver unit for wirelessly receiving the transmitted images, a vehicle control unit coupled to the vehicle transceiver unit, a display coupled to the vehicle control unit for displaying the received images inside the normal viewing area of the vehicle driver, and a second plurality of docking connectors removably interconnected, both physically and electrically, to the first plurality of docking connectors at a docking station and coupled to the vehicle control unit. The first and second plurality of docking connectors couple camera control signals from the vehicle control unit to the camera control unit when the first and second plurality of docking connectors are physically and electrically interconnected. The camera control signals are wirelessly transmitted by the vehicle transceiver unit and wirelessly received by the camera transceiver unit when the camera unit is removed from the docking station.
The camera control signals may include on and off signals for turning the camera on and off, respectively.
The camera may include a zoom lens wherein the camera control signals include a zoom control signal for controlling the zoom lens.
The camera unit may include at least one motor coupled to the camera wherein the camera control signals include at least one motor control signal for controlling movement of the camera.
The camera unit may include a tilt motor and a scan motor both coupled to the camera wherein the camera control signals include motor control signals for controlling tilt and scan of the camera.
The system may further include a manually-operable driver control unit coupled to the vehicle control unit for generating the camera control signals.
The camera unit may include a battery coupled to the camera control unit for powering the camera unit. The battery may be a rechargeable battery wherein the first and second plurality of docking connectors couple power signals to the camera unit to recharge the rechargeable battery at the docking station.
The camera unit may include a housing for housing the camera, the camera control unit, the camera transceiver unit and the first plurality of docking connectors.
The system may further include a mechanism for removably mounting the camera unit to a vehicle or a trailer. The mechanism may include at least one suction cup, at least one magnet or at least one pair of hold downs.
The above objects and other objects, features, and advantages of the present invention are readily apparent from the following detailed description of the best mode for carrying out the invention when taken in connection with the accompanying drawings.
