Z-axis sensing pointing stick with base as strain concentrator
First Claim
1. A device for controlling the movement of an object on a display screen, comprising:
- a) a shaft having a longitudinal length oriented along a first axis;
b) a base having the shaft mounted thereinto; and
c) a sensor, mounted circumferentialy around the shaft oriented along the first axis, and extending into the base, for conditioning an output signal indicative of a force exerted on the shaft.

Abstract
A pointing stick for controlling the positioning, movement and operation of a cursor on the display screen. Strain gages 30 are mounted on the sides of the stick 12 and are made of pressure sensitive strips 32, for electrically changing the resistance of the material in response to the amount of strain applied thereto. A conductive contact bridge 34 for electrically connecting the two strips 32, and conductive contact pads 36 for making electrical contact to electronic circuitry (not shown) are also mounted on the sides of the stick 12. The stick 12 extends through a hole 38 in the base 4 in a Z-axis oriented direction 39, and is held in place by an adhesive bond epoxy 40. Cable 18 is positioned within cavity 16 and adhesively bonded to the cavity wall via adhesive 42. Cable 18 has electrical traces 44 and input/output (I/O) pads 46 mounted thereon. Contact pads 36 are bonded to I/O pads 46 by any suitable bond material 50.

34. A keyboard for entering data in an information system, comprising:
-
a) a homerow of keys located on the keyboard for locating fingers of a user during typing; and b) a cursor control device, mounted on the keyboard, for allowing a user to both select an item on a display device and control the movement of a cursor on the display device by using a single finger of the user while the remaining fingers reside inactive on the homerow, the device including; b1) resistor means, electrically connected in a bridge such that the bridge has a first resistance value when the item is in an inactive state and has a second resistance value when the item is in an active state; a) a shaft, located between and extending up toward a top surface of the two keys, having a longitudinal length oriented along a first axis extending toward the top surface, the resistor means circumferentialy mounted to the shaft; and
resistor means extending into the base. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
