摘要： A computer keyboard assembly has flexible membrane that is located adjacent a housing. The flexible membrane has circuit lines and an integral pointing stick cable. The circuit lines extend onto the pointing stick cable from the flexible membrane. Keys are electrically connected to the circuit lines. A backing plate structurally supports the flexible membrane. The membrane is located between the backing plate and the housing. A pointing module is attached to the backing plate. The pointing module is electrically connected to the pointing stick cable such that electrical signals from the pointing module are conducted to the circuit lines on the pointing stick cable. The pointing stick cable wraps around a side of the backing plate.

摘要： A device for generating conditioned electrical signals in response to forces applied to the device. The device includes a shaft attached to a substrate. Several strain sensitive resistors are mounted on the substrate around the shaft for generating an electrical signal representative of a magnitude and direction of force applied to the shaft by a user. Several apertures are in the substrate, each aperture is located between a pair of strain sensitive resistors. The apertures concentrate the stress on the resistors. A signal conditioning device is mounted to the substrate and is electrically connected to the resistors for conditioning the electrical signal. The signal conditioning device receives the electrical signal in an analog form and provides a conditioned signal as an output in a digital form. The device is mounted to a keyboard base. An alternative embodiment is shown using a cavity instead of apertures in the substrate.

摘要： A thermal printer that includes a thermally conductive sacrificial member disposed between the thermal print head and the web. The sacrificial member is held generally under tension and prevents the web from directly engaging the thermal print head. The sacrificial member may take one of many different forms, including a fixed strip or belt, a rotatable, continuous belt which slowly recirculates during printing to equalize wear across its surface, or a Moebius loop which further provides that wear is equalized across both sides of the belt. By providing a sacrificial member between the print head and web, wear and exposure of the print head is reduced, thereby prolonging the life of the print head.

摘要： The cost and complexity of connecting electrically actuated devices to a game control microprocessor in a coin operated amusement game can be reduced by utilizing a standard control assembly including a memory element for each of the devices and where a control circuit is used to connect the assemblies in series with the microprocessor. Data and clock lines in the control circuit are used to transmit control signals to the devices and the control circuit can additionally include power supply lines and a ground line. A similar arrangement can be used to transport data representing the status of game operated switches to the microprocessor.

摘要： A ribbon cartridge for a thermal transfer printer is configured to provide a retractable feed for a donor ribbon. The ribbon cartridge includes a housing, a roll of donor ribbon wound on a core within the housing, and a clutch operatively coupled to the core. A resilient structure is coupled to the clutch and to the cartridge housing such that the release of energy stored in the resilient structure by advance of the donor ribbon produces retraction of ribbon slack, if the donor ribbon is released or backfed. Alternatively, a ribbon roll having a self-contained clutching and slack take-up capability includes a hollow core configured to receive a roll of ribbon and a clutch having a friction component configured to induce frictional engagement with the core. At least one end of the clutch is adapted to be externally constrained, and a resilient component is located between the friction component and at least one end of the clutch.

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.
