Abstract: Electrographic sensor and method for position determination of a selected position thereon. Sensor includes a conductive material layer having electrical resistivity and a surface, at least three spaced apart contact points electrically interconnected with the layer, a processor connected to the contacts disposed to selectively apply a signal to each contact, and a probe assembly that includes either a stylus coupled to the processor with the stylus disposed to be positioned by a user in vicinity of the selected position on the layer, or a flexible layer with a user's finger selecting that position on the flexible layer to receive signals from the layer when the contact points have signals selectively applied. The selected position is determined by the processor from signals received from the stylus, or flexible layer, each in relation to a similar excitation of different pairs of the contacts. The conductive layer of either two or three dimensions including a closed three dimensional shape.

Abstract: An apparatus and method for broadcast burst transmission of compressed audio/video programs from a stored library to a multiplicity of subscibers. The stored programs are burst transmitted repeatedly in a predetermined sequence of entire programs or segments thereof to a receiver at each subscriber's location. Each receiver is operative for accessing the predetermined broadcast schedule, inputting a subscriber's order for one or more programs, monitoring the broadcast burst transmissions for the one or more ordered programs, receiving the one or more ordered programs in a burst time period corresponding to the time period of the burst transmission, and storing the one or more ordered programs. The subscriber then enjoys full VCR-like control over playback at his convenience of the ordered, stored programs, that are then decompressed by the receiver for viewing in real time.

Abstract: An improved video recorder/transceiver with expanded functionality ("VCR-ET") including a capability for storing video and video programs in digital format, editing such programs, transferring such programs onto a hard copy magnetic media, and transmitting such programs to a remote location using a second VCR-ET. The increased functionality is realized through the use of analog to digital conversion, signal compression and intermediate storage in an integrated circuit, random access memory. The recorder/transmitter has capabilities to transmit and receive program information in either a compressed or decompressed format over fiber optic lines, conventional phone lines or microwaves.

Abstract: An improved video recorder/transmitter with expanded functionality including a capability for editing and/or copying from one video tape to another using only a single tape deck. The increased functionality is realized through the use of analog to digital conversion, signal compression and intermediate storage in an integrated circuit, random access memory. The recorder/transmitter has capabilities to transmit and receive program information in either a compressed or decompressed format over fiber optic lines.
