Abstract: The present invention relates to a resilient hollow grip cap for removable mounting on the top of a computer control device i.e., a finger actuated pointing stick. The cap has a plurality of short fibers adhered to its outer surface and extending outwardly away from the surface of the cap.

Abstract: A method and means for flash charging a plurality of phosphorescent-coated, touch-sensitive keys using a planar, light-transmissive multicolor liquid crystal display (LCD) where the tripping event is the position of a lid of the notebook within a critical angle of the base.

Abstract: A pointer system provides multiple display pointers that can be created and identified by a computer user such that each pointer is associated with a particular application and location within an application. A user can recall respective pointers and pointer locations by selecting a pointer identifier. One or more of the pointers can be defined as anchored pointers, which are associated with one or more user actions. The user actions can comprise a variety of functions, including mouse button clicks. In this way, a user can define anchored pointers and carry out a string of user actions by selecting the identifying character of an anchored pointer.

Abstract: An arrangement for enhancing the observability of a multicolored liquid crystal display in a computer of the notebook type using an arrangement in which the top lid of the laptop is mechanically separated into a diffuser/reflective surface and the LCD in its frame, the diffusing/reflecting lid is attached through a slider and linkage arrangement permitting the diffuser/reflector to act as a flat field illuminator and to move in a plane, apart from, yet forming a dihedral angle with the plane of the LCD. The lid so positioned can opportunistically reflect ambient light through the plane of the LCD. Also, by causing the lid to project over the plane of the LCD, it secures a contrast-maintaining shadow otherwise bleached by light incident to the LCD viewing surface.

Abstract: A user-manipulable sensor apparatus is provided for allowing a user to input, through hand manipulation of a movable member, motion in six degrees of freedom: translational motion in the X, Y, and Z axes, and rotation about each of those three axes. The apparatus includes a central member which acts as a stationary reference, and a user-manipulable member, such as a spherical, hollow member which substantially surrounds the central member. Flexible wire or in-line strain gauges are coupled between the central member and the inside surface of the user-manipulable member, to hold the user-manipulable member in a quiescent position, relative to a position of the central member. Accordingly, there is no need for additional support members for holding the user-manipulable member in position. Manipulation of the user-manipulable member causes tension on various ones of the strain gauges. The strain gauges produce signals, from which the motion of the user-manipulable member may be computed.

Abstract: Enhanced visibility of icons and other types of menu items is provided by increasing size and or skew or both of one or more icons or menu items in a generally inverse relation to proximity of a cursor image address to particular icons or menu items. Increase of size enhances user recognition of an ordinarily small menu item or icon and simultaneously provides the effect of stabilizing cursor position during selection without affecting linearity of response to a graphic input device. Skew and repeated expansion may be used to attract user attention while repeated expansion simplifies icon manipulation by the user in determining a response to a mandatory input demand from an application.

Abstract: A World Wide Web terminal appliance utilizes a disk drive for local storage of Web pages previously downloaded and rendered for display during the course of a Web surfing session. The disk drive rotates at a rate substantially in synchronization with a display refresh time interval of a display device, preferably a raster refresh cycle time of a video monitor. Therefore, the image being displayed need not occupy random-access memory, but rather is sent directly from the disk to a display interface for coupling to the display device. Little or no RAM buffering is required, so the appliance need not include a large quantity of video RAM storage. A relatively inexpensive disk is used instead, thereby bringing about advantageous cost savings.

Abstract: A pointing system for controlling a cursor on a computer display device includes a single control actuator that ordinarily controls movement of the cursor on the display device and also detects if an applied cursor force matches a predetermined tap signature. If the applied force substantially matches the predetermined tap signature, then the system responds to the applied force by initiating one or more display actions rather than by moving the display cursor. The system detects tap signature forces applied along the x, y, and z axes of the control actuator and responds by retrieving a cursor context comprising a window display and corresponding cursor location from a queue and opening the associated window. That is, the system changes the active window from among windows of a graphical user interface, preserving the cursor position within each window. Other tap signature responses can correspond to functions initiated by programmable function keys or to user-defined functions.

Abstract: A threshold discrimination filter circuit compares an amplitude and rate of change of amplitude of an output of a graphic input device such as an isometric joystick including strain gauges and a fixed resistance in a hierarchical voltage divider with threshold reference signals and corrects the output of the graphic input device based on previously stored samples thereof when a selection or deselection action by a user is discriminated. Outputs of the graphic input device are supplied directly to a CPU of a data processing device between masking periods so that graphic manipulations such as dragging can be performed while masking unintended change of specified display location during selection and deselection.

Abstract: An integrated manual control input device is provided for use in a computer system having a graphical user interface. The device comprises a keyboard unit having a plurality of keys, a pointing actuator mounted to the keyboard between preselected ones of the keys for engagement by a user's index finger, at least one click button assembly pivotably mounted to the keyboard unit adjacent the keys and a normally open momentary switch beneath the click button assembly. The click button assembly has a button moveable downwardly by a user's thumb to select an ON state and subsequently releasable to select an OFF state. The button is also moveable downwardly and slidable laterally in a rearward direction to select a locked ON state to facilitate a drag operation.

Abstract: A swivel plug is provided which has male and female plug portions which pivot 180.degree. with respect to one another about a common pivot axis between first and second positions. A plurality of male and female electrical contact pairs slidably engage one another and pivot about the common pivot axis. Male and female bodies, which receive the electrical contact pairs, also pivot with respect to one another about the common pivot axis. The male and female bodies and the male and female electrical contact pairs are arranged in a novel relationship to mutually retain one other for the pivotal movement. The swivel plug eliminates the need for an electrical cord between an adapter of a laptop computer and a wall receptacle which has a downwardly located ground receptacle or a wall receptacle which has an upwardly located ground receptacle. The swivel plug also enables plugging a computer adapter or a typical extension cord into a receptacle where there is a rigid space constraint.
