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.

摘要： A computer keyboard has a pointing stick integrally molded into and projecting from a surface of a plastic housing. Keyboard keys extend through holes in the same plastic housing. Strain-sensitive resistors are formed in a small location onto a circuit substrate. The same circuit substrate that carries the strain-sensitive resistors also carries conductive pads for the key switches. The strain-sensitive resistor location is bonded to the housing adjacent the pointing stick, but on an opposite surface of the housing from the pointing stick protrusion.

摘要： A pointing device for controlling the positioning, movement and operation of a cursor on the display screen. Specifically, there is a pointing stick assembly using resistive material strain gages mounted on the sides of a shaft or stick for sensing when the stick is experiencing stresses and strains therein because of an applied force to the stick. The pointing stick has a stick supporting collar securely attached to a substrate. The collar extends from the substrate to approximately around the location of the strain gages. The collar may have a beveled surface located between opposing surfaces of the collar and shaft.

摘要： An apparatus (10) and method for the automatic insertion of terminals (84) into cavities (16) of a ceramic substrate (15). A continuous carrier web (80) is advanced from a reel (90), into an automatic terminal insertion apparatus (10) simultaneously with the automatic advancement of substrates (15) along a trackway (20). As a substrate (15) is secured by a securement and lateral transmission apparatus (170) and moved laterally from the trackway (20) to align the substrate cavities (16) with associated transmittal barrels (162), a web hold down apparatus (130) secures web portion (82) of carrier web (80) and the cut-off blade (146) of a separation block (144) moves downwardly to separate a predetermined number of terminals (84) from the web portion (82) and locate the terminals in transmittal slots (152) located in a subjacent pressure pad (150). The separation block (144) and subjacent pressure pad (150) enclose the separated terminals (84) in transmittal slots (152) and move downwardly together to align the transmittal slots (152) with transmittal barrels (162). Compressed air is injected into the slots (152) and propels the terminals (84) through the slots (152) and aligned transmittal barrels (162) into the respective substrate cavities (16). The severed end of each terminal (84) bites into the respective cavity walls to securely anchor the terminals (84) in the substrate cavities (16), all without any swaging, scratching, marring, or damage to the exterior portions of the terminals. The exterior portion of each terminal is undamaged, has no cut marks, and plated terminals retain their protection against corrosion.
