摘要： A ball grid array resistor network has a substrate that has top and bottom surfaces. Resistors are disposed on the top surface. Conductors are disposed on the top surface, and each conductor is electrically connected to an end of each resistor. Vias extend through the substrate and are electrically connected to the conductors. Solder spheres are disposed on the bottom surface, and are electrically connected to the vias. A cover coat is disposed over the conductors and resistors. In an alternative embodiment, the vias are eliminated and the resistor network is formed on the bottom surface of the substrate. The resistor network provides a high density of resistors per unit area.

摘要： A pointing stick for controlling cursor movement on a display screen of a computer system that is mountable to a surface of a printed circuit board. The pointing stick has a base member and a shaft having mounted in the base member. Several sensors are mounted around the shaft for sensing the amount of strain in the shaft that is created in response to an applied force on the shaft. The sensors generate an electrical signal in response to the applied force. A pair of spaced electrical leads are located on opposing sides of the base member and extend partially through the base member. Each of the electrical leads has several inner terminal ends that are electrically connected to the sensors. Several outer terminal ends extend outwardly of the base member and are shaped for mounting on the surface of a circuit board. An electronic component is attached to the shaft or the leads and is electrically connected to the inner terminal ends. The electronic component receives the electrical signal from the sensors as an input and generates a conditioned electrical signal as an output.

摘要： A test system for performing a test of strain gauge resistors used on a pointing stick. The test system has a mechanical load applicator that holds the resistor and applies a mechanical force to the resistor. An electrical contactor makes and breaks an electrical connection with the resistor. An electrical tester is connected to the electrical contactor to measure electrical parameters of the resistor with and without the mechanical force. A calculator is connected to the tester and calculates several resistor parameters. The resistor parameters are indicative of the operation of the pointing stick.

摘要： A pointing stick for controlling the positioning, movement and operation of a cursor on the display screen. Specifically, there is a pointing stick that both directs a cursor and acts as the activation button for selecting items on the display screen by tapping on the pointing stick instead of clicking on a mouse button. Uniquely, the device is made of a shaft (12) having a longitudinal length oriented along a first axis (39) and having a top surface that is perpendicular to the first axis, there is a vertical force sensor (59, or 71), mounted on the top surface of the shaft, for sensing a vertical oriented force applied to the shaft along the first axis. Cap (24), has a cavity (81) with a top surface (79) therein, where the top surface of the shaft is positioned within the cavity and spaced from and juxtaposed to the top surface of the cavity. In one embodiment the vertical sensor includes first and second electrically conductive pads that are electrically isolated from each other. The vertical sensor also has a flexible conductive layer positioned next to the top surface of the cavity of the cap. Additionally, the vertical sensor has an electrically insulative spacer (78) shaped to position the first and second pads away from the flexible conductive layer. In a second embodiment, the vertical sensor comprises a pressure sensitive layer (60) located on the top surface of the shaft. Additionally, the alternative vertical sensor has a strain concentrator, shaped and positioned to concentrate a z-axis oriented force applied to the cap to effect the electrical conductivity of the pressure sensitive layer.

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.
