Abstract

A gimbal assembly including a gimbal housing having opposed first and second yoke portions dimensioned and configured to receive a surveillance device therebetween, the yoke portions defining a gimbal axis about which the surveillance device can rotate relative to the gimbal housing, and a drive assembly disposed within the first yoke portion of the gimbal housing for driving the surveillance device about the gimbal axis, the drive assembly having a connector adapted and configured to mate with and pass electrical signals to and from a corresponding connector on the surveillance device, wherein the second yoke portion is detachable from the gimbal housing to gain access to the surveillance device and the surveillance device is removably connected to the drive assembly.

Claims

1. A gimbal assembly comprising:

a) a gimbal housing having opposed first and second yoke portions dimensioned and configured to receive an electrical device therebetween, the yoke portions defining a gimbal axis about which the electrical device can rotate relative to the gimbal housing; and

b) a drive assembly disposed within the first yoke portion of the gimbal housing for driving the electrical device about the gimbal axis, the drive assembly having a main wheel member including;

a pair of forwardly projecting alignment pins for engaging corresponding alignment ports on the electrical device;

a slip ring adapted and configured to pass electrical signals to and from the electrical device; and

an encoder wheel disposed circumferentially around the slip ring to provide feedback on the angular position of the electrical device relative to the gimbal axis, wherein the second yoke portion is detachable from the gimbal housing to gain access to the electrical device.

2. A gimbal assembly as recited in claim 1, where the electrical device is removably connected to the drive assembly.

3. A gimbal assembly as recited in claim 2, wherein the drive assembly includes a compressible connector for temporarily coupling with a mating connector on the electrical device.

4. A gimbal assembly as recited in claim 1, wherein the electrical device is a camera device.

5. A gimbal assembly as recited in claim 1, wherein the electrical device is an infrared sensing device.

6. A gimbal assembly as recited in claim 1, wherein the drive assembly includes means for interfacing with a drive motor.

7. A gimbal assembly as recited in claim 1, wherein the gimbal housing is adapted and configured for rotation about a main axis extending perpendicular to the gimbal axis.

8. A gimbal assembly as recited in claim 1, wherein the main wheel member includes a printed circuit board coupled to the slip ring, the printed circuit board including a compressible connector configured to establish a temporary connection with a corresponding connector on the electronic device.

9. A gimbal assembly as recited in claim 8, wherein an array of spring-loaded pins included on the compressible connector electronically connects the printed circuit board to a circuit with the electronic device.

10. A gimbal assembly comprising:

a) a gimbal housing having a yoke portion dimensioned and configured to receive a surveillance device, the yoke portion defining a gimbal axis about which the surveillance device can rotate relative to the gimbal housing; and

b) a drive assembly disposed within the yoke portion of the gimbal housing for driving the surveillance device about the gimbal axis, the drive assembly including;

a slip ring component adapted and configured to pass electrical signals to and from the surveillance device; and

an encoder wheel disposed circumferentially around the slip ring to provide feedback on the angular position of the electrical device relative to the gimbal axis,

wherein the surveillance device is removably connected to the drive assembly.

11. A gimbal assembly as recited in claim 10, wherein the drive assembly includes means for interfacing with a drive motor.

12. A gimbal assembly as recited in claim 10, wherein the drive assembly includes a compressible connector for temporarily coupling with a mating connector on the surveillance device.

13. A gimbal assembly as recited in claim 10, wherein the drive assembly includes alignment pins for engaging corresponding alignment ports on the surveillance device.

14. A gimbal assembly as recited in claim 10, wherein the gimbal housing is adapted and configured for rotation about a main axis extending perpendicular to the gimbal axis.

15. A gimbal assembly comprising:

a) a gimbal housing having opposed first and second yoke portions dimensioned and configured to receive a surveillance device therebetween, the yoke portions defining a gimbal axis about which the surveillance device can rotate relative to the gimbal housing; and

b) a drive assembly disposed within the first yoke portion of the gimbal housing for driving the surveillance device about the gimbal axis, the drive assembly including;

a slip ring component adapted and configured to pass electrical signals to and from the surveillance device; and

an encoder wheel disposed circumferentially around the slip ring to provide feedback on the angular position of the electrical device relative to the gimbal axis,

wherein the second yoke portion is detachable from the gimbal housing to gain access to the surveillance device and the surveillance device is removably connected to the drive assembly by a compressible connector array.

16. A gimbal assembly as recited in claim 15, wherein the surveillance device is a camera device.

17. A gimbal assembly as recited in claim 15, wherein the surveillance device is an infrared sensing device.
