Abstract: A disabling device for a computer mouse allowing the operator to lock the pointer/cursor in the chosen spot on the screen and prevent any unintended and unpredictable input signals from the an idle computer mouse to the computer system, thereby ameliorating unnecessary movement of the mouse to reinstall the pointer/cursor in the proper position on the screen and to correct any possible wrong interaction with the computer before resuming the mouse operation again.

Abstract: A portable, universal video and audio computer tester has a video section including a pluggable video connector for connecting to an external source of a video signal; a video detector for detecting an input RGB video signal; a video indicator for signaling presence of an input RGB video signal; a synch detector for detecting an input video synchronization signal; and, synch indicating means for signaling presence of a and input horizontal and a vertical synchronization signal. An audio section has pluggable audio connectors; an internal audio generator for creating an output audio signal; an audio indicator for signaling presence of an input audio signal from the external source or from the internal audio generator; a switch for changing an operational mode from an input audio signal to an output audio signal. Connection to either an external or internal power supply is provided.

Abstract: A portable personal wrist supporting device for use with a table supported keyboard is constructed of a carriage having an upper, wrist supporting face and a lower, frictionless, table engaging face, and a wrist band for securing a wrist of a keyboard operator resting on the upper face. The carriage has an above-table height between upper and lower faces such that the operator's hand will be aligned for free operative access over the entire keyboard through movement of the carriage across the table. The frictionless surface is formed by a plurality of balls mounted on the lower face. The carriage of the device is symmetrical enabling use thereof by either hand.

Abstract: A visual paging device comprises a LED or LCD screen for displaying a personal message which can be input by the user through a keyboard on the device itself or through a computer at a rental location to which the device can be releasibly connected or, by an infrared remote keyboard. A stand supports the screen on a wheeled base for easy transportation from the rental location to a meeting area and is adjustable in height enabling the message to be displayed above a crowd.

Abstract: Simulated observation flight apparatus includes a cabin mounted for passenger transportation to very high tower observation deck. The cabin houses display means producing a window-type display, display storage devices to play a real-life panorama or other picture, remote microprocessors to control display storage devices and to produce computer generated pictures on said display means, a CPU to control the cabin movement, to synchronize the display change with the movement of the cabin and to control remote microprocessors. The cabin also houses panels comprising indicators for monitoring current information data, speakers for audio accompaniment, user operable control means for interacting with the displayed picture, for playing a game and for limited control of the cabin movement to create a brief sense of weightlessness.
