## CPC

- G06F 3/0362: with detection of one-dimensional [1D] translations or rotations of an operating part of the device, e.g. scroll wheels, sliders, knobs, rollers or belts

## Abstract

An apparatus for controlling the position of a cursor on the display of a computer comprising a first cylindrical member and a second cylindrical member concentrically engaging the first cylindrical member and coupled thereon for both rotational relative movement and translational relative movement. A detector is provided for sensing this relative movement and providing signals representative thereof to a computer for controlling the position of a cursor on the display. This apparatus is especially suitable for use on a vehicle carrying an onboard computer and could, for example, be mounted on the steering post of the vehicle.

## Claims

### Claim 1

An apparatus for controlling the position of a cursor on a display of a computer, comprising:
a first member;
a second member concentrically engaging said first member and coupled thereto for a first type of relative movement and a second type of relative movement;
a detector coupled to sense said first type of relative movement and said second type of relative movement between said first member and said second member and for generating first and second signals in response thereto;
wherein said first signal and said second signal are coupled to a computer for controlling the position of the cursor;
wherein the computer and the display are components of an onboard computer system deployed in an automobile having a steering column; and
wherein the first member is mounted on said steering column.

### Claim 2 (depends on 1)

An apparatus according to claim 1 wherein said relative movement of said first type is translational.

### Claim 3 (depends on 2)

An apparatus according to claim 2 wherein said relative movement of said second type is rotational.

### Claim 4 (depends on 1)

An apparatus according to claim 1 wherein said first member is substantially cylindrical and said second member is substantially cylindrical.

### Claim 5 (depends on 4)

An apparatus according to claim 4 wherein said relative movement of said first type is translational and wherein said relative movement of said second type is rotational.

### Claim 6 (depends on 4)

An apparatus according to claim 4 further comprising at least a first switch coupled to said second member which when activated instructs the computer to perform a first function.

### Claim 7 (depends on 6)

An apparatus according to claim 6 further comprising a second switch coupled to said second member which when activated instructs the computer to perform a second function.

### Claim 8 (depends on 6)

An apparatus according to claim 6 wherein said first function is related to the position of the cursor.

### Claim 9

An apparatus for controlling the position of a cursor on a display of an onboard computer deployed in a vehicle having a steering assembly, comprising:
a first member mechanically coupled to said steering assembly;
a second member concentrically engaging said first member and coupled thereto for movement of a first type thereon and movement of a second type thereon;
a detector coupled to sense relative movement of said first and second type between said first member and said second member and for generating first and second signals respectively corresponding thereto, said first and second signals being coupled to the computer for controlling the position of the cursor on the display; and
at least a first switch coupled to said second member which, when activated, instructs the computer to perform a first function related to the position of the cursor.

### Claim 10 (depends on 9)

An apparatus according to claim 9 wherein said first and second members are substantially cylindrical.

### Claim 11 (depends on 10)

An apparatus according to claim 10 wherein said first relative movement is translational and said second relative movement is cylindrical.

### Claim 12 (depends on 11)

An apparatus according to claim 11 further comprising
at least a second switch coupled to said second member which, when activated, instructs the computer to perform a second function.
