A system for remotely observing and optionally controlling information, including text and graphical images, displayed on a computer from among both homogeneous and heterogeneous computers coupled in a network or via other transport media such as magnetic disks captures window system event messages ...
An improved video system that enables a player to interact with mid-air stereo perception images of foreshortened perspective animation and with animation displayed on the projection screen or monitor, by controlling the motions of a robotic simulation apparatus deployed in front of the projection s ...
An improved video system that enables a player to interact with mid-air stereo perception images of foreshortened perspective animation and return the animation back to the playing field on the projection screen or monitor, or to effect other interactive dramatics with the animation. The improvement ...
A communication system uses simple microwave transmitters disposed along roadways and in-vehicle mounted receivers to transmit encoded signals to produce location-specific commercial, traffic regulatory, emergency and other information to operators of motor vehicles. An optional remote interface lin ...
A general purpose computer, such as a personal computer, is programmed for sound-synchronized random access and display of synthesized actors ("synactors") on a frame-by-frame basis. The interface between a user and the animation system is defined as a stage or acting metaphor. The user interface pr ...
A differentially encoded digital signal waveform is generated as a discrete time representation of a desired analog signal utilizing multi-frequency modulation techniques. The computational capability of present day, industry-standard microcomputers equipped with a floating point array processor or ...
A video system enables the operator to repeatedly touch a study object to change the action according to dramatics or game on a video display.
Information pathways for communications among personnel, among computers, and between personnel and computers, in a local communication system, including remote communications via leased lines or the public network is described. To a public central office, the present invention appears as a private ...
A controller for controlling a microprocessor-based system incorporates two cooperatively operating state machine controllers and is capable of interfacing with bus and memory subsystems while maintaining synchronous handshake with more than one type of microprocessor on a bus which may operate at a ...
A user-orientated telephone instrument including high-fidelity speech encoding, encryption capability and many function presently provided by centralized call processing is described. Utilizing an ADPCM encoding process including forward error correction, a high quality relatively noise immune signa ...
