Abstract

The present invention provides devices for controlling a desired output of an output device. These devices include a first conductor, a second conductor having a varying, predetermined spacing from the first conductor, and a third conductor positioned on the actuator mechanism and having a plurality of interconnecting positions between the first conductor and the second conductor. A predetermined one of a plurality of output signals may be produced when the third conductor connects the first conductor and the second conductor to control the desired output of the output device.

Claims

1. A signal-producing mechanism, comprising:

an actuator mechanism movable in a plurality of directions;

a first conductor having a circular shape;

a second conductor having a circular shape and positioned non-concentrically within the first conductor so as to have a varying, predetermined spacing from the first conductor;

a third conductor positioned on the actuator mechanism and having a plurality of interconnecting positions between the first conductor and the second conductor, the interconnecting positions corresponding to the plurality of mobility directions of the actuator mechanism, wherein the third conductor further comprises a variable resistance portion having an independent resistance value in each one of the plurality of interconnecting positions; and

a predetermined one of a plurality of output signals producible when the third conductor connects the first conductor and the second conductor in each of the plurality of interconnecting positions.

2. The signal-producing mechanism of claim 1, wherein at least one of the plurality of interconnecting positions corresponds to one of a plurality of variable resistance configurations defined by predetermined interconnected portions of the first conductor, the second conductor and the third conductor.

3. The signal-producing mechanism of claim 1, wherein at least two of the first conductor, the second conductor and the third conductor have at least one position in a substantially different plane than the remaining one of the first conductor, the second conductor and the third conductor.

4. The signal-producing mechanism of claim 1, wherein the third conductor comprises a portion of a first conductive ring having an at least partially conical surface, wherein the portion of the first conductive ring is movable between a first plane and a second plane, and wherein the portion of the first conductive ring connects the first conductor and the second conductor in the second plane.

5. The signal-producing mechanism of claim 1, wherein at least two of the first conductor, the second conductor and the third conductor have known electric characteristics such that the predetermined one of the plurality of output signals is determinable via voltage division.

6. The signal-producing mechanism of claim 1, wherein the predetermined one of the plurality of output signals varies depending upon a time period during which the third conductor connects the first conductor and the second conductor in one of the plurality of interconnecting positions.

7. A signal-producing mechanism, comprising:

an actuator mechanism movable in a plurality of directions;

a first conductor;

a second conductor having a varying, predetermined spacing from the first conductor;

a third conductor positioned on the actuator mechanism and having a plurality of interconnecting positions between the first conductor and the second conductor, the interconnecting positions corresponding to the plurality of mobility directions of the actuator mechanism;

a predetermined one of a plurality of output signals producible when the third conductor connects the first conductor and the second conductor in each of the plurality of interconnecting positions; and

a signal analyzer and a controllable device, wherein the signal analyzer is operable to receive and process the predetermined output signal of the plurality of output signals and generate a predetermined control signal from a plurality of control signals to control a predetermined function associated with the controllable device.

8. The signal-producing mechanism of claim 7, wherein the controllable device comprises a wireless electrical device having a visual display with a movable graphic, and wherein the predetermined function comprises a positioning of the movable graphic on the visual display in a selected direction.
