Abstract

A system including a user input device for controlling a position of medical equipment is described. In an example embodiment, the user input device is configured to be coupled to the medical equipment and is responsive to an operator input representation of a desired movement of the equipment. A processor determines a direction in which the operator desires the equipment to move based on a device output.

Claims

1. A sensor comprising a core having an outer surface, a plurality of sensing areas on said outer surface, each said sensing area responsive to at least one object within a sensory field of said sensor, wherein the at least one object comprises at least one of an operator input representative of a desired movement of said movable member and an obstacle in proximity with said movable member.

2. A sensor according to claim 1 wherein said core comprises plastic, and wherein each of said sensing areas comprises a conductive foil bonded to said plastic.

3. A sensor according to claim 1 wherein said core has one of a circular and rectangular cross sectional shape.

4. A sensor according to claim 1 wherein a ground plane is at a periphery of each sensing area.

5. A sensor according to claim 1 wherein the operator input is based on a position of an operator'"'"'s hand.

6. A sensor according to claim 1 further comprising eight sensing areas, each of said sensing areas comprising a conductive foil, and ground planes at a periphery of each said sensing area.

7. A sensor according to claim 1 further comprising thirty two sensing areas, each sensing area coupled to a matrix switch.

8. A sensor according to claim 1 wherein said sensors comprise at least one of a capacitance sensor, an infrared sensor, and an ultrasonic sensor.

9. A sensor according to claim 1 wherein said sensor determines both a speed and a direction in which the equipment is to be moved.

10. A sensor according to claim 1 wherein at least some of said sensors comprise capacitance sensors, each of said capacitance sensors being one of a proximity sensor and a touch based sensor.

11. A sensor according to claim 1 wherein said sensor is responsive to a position and speed of an operator'"'"'s hand with respect to said sensor.
