Abstract

A chassis pivotally engages a scanning assembly. The scanning assembly provides a video camera, a circuit board assembly, a frame and a positioning gear, with the positioning gear able to rotate over an arcuate field of view for the camera. The chassis fixedly mounts a drive motor including a drive gear engaging the positioning gear for rotating the video camera. The frame provides opposing tabs positioned for contact with the chassis at ends of the selected arc so as to limit the range of camera motion. The chassis, scanning assembly and drive motor are mounted within a case providing a window of such curvature as to maintain a constant space between the camera and the window during camera scanning.

Claims

1. A scanning video camera system apparatus comprising:

a chassis pivotally engaging a scanning assembly, the scanning assembly having a video camera, a frame and a positioning gear, thereby enabling the scanning assembly to rotate over a selected arc for directing the video camera;

the chassis fixedly mounting a drive motor including a drive gear, the drive gear engaging the positioning gear for rotating the scanning assembly over the selected arc;

the frame providing opposing tabs positioned for contact with the chassis at ends of the selected arc so as to limit the range of arcuate motion of the camera;

the chassis, scanning assembly and drive motor mounted within a case with a circuit board assembly for processing video signals from the camera;

the case providing a window of such curvature as to maintain a constant space between the camera and the window as the camera scans the selected arc.

2. The apparatus of claim 1 further providing a heater element positioned for movement with the positioning gear in adjacency to the window for defogging the window.

3. The apparatus of claim 1 further providing at least one infrared lamp mounted onto the chassis in a position for directing infrared illumination through the window.

4. The apparatus of claim 3 further providing a partition positioned between the at least one infrared lamp and the camera such that infrared illumination cannot enter the camera.

5. A scanning video camera system apparatus for mounting on a motor home, the apparatus comprising:

a chassis pivotally engaging a scanning assembly, the scanning assembly having a video camera, a frame and a positioning gear, thereby enabling the scanning assembly to rotate over a selected arc for directing a field of view of the video camera;

the chassis fixedly mounting a drive motor including a drive gear, the drive gear engaging the positioning gear for rotating the scanning assembly;

the frame providing opposing tabs positioned for contact with the chassis at ends of the selected arc so as to limit the range of arcuate motion of the camera;

the chassis, scanning assembly and drive motor mounted within a case with a circuit board assembly for processing video signals from the camera;

the case providing a window of such curvature as to maintain a constant space between the camera and the window as the camera scans the selected arc, and a video monitor positioned within a cab of the motor home and engaged for signal communication with the apparatus so as to enable remote viewing from the cab.

6. The apparatus of claim 5 further providing a heater element positioned for movement with the scanning assembly in adjacency to the window for defogging the window.

7. The apparatus of claim 5 further providing at least one infrared lamp mounted onto the chassis in a position for directing infrared illumination through the window.

8. The apparatus of claim 7 further providing a partition positioned between the at least one infrared lamp and the camera such that infrared illumination cannot enter the camera.
