Abstract: In a system for editing documents having text and voice components, portions of a document are selected by cursor control to display text characters and associated voice symbols or tokens representing the voice component position and time-length.

Abstract: A dictation and editing system includes microphone and keyboard inputs to a programmed computer system. The author may control the selection and entry of microphone and keyboard inputs for storage and display. Keyboard entries are displayed as alpha-numeric or other characters, while recorded speech is displayed simply as a sequence of box-like characters called voice token marks. Each token mark indicates 1 second of speech, and one line of marks represents 60 seconds of speech.

Abstract: In a communication facility a masterstation initially directs a single inquiry signal to the aggregate of the operating stations and receives a response from this aggregate indicating by its structure which of the several individual stations currently needs service from the communication facility. Messages are thereafter exchanged between the masterstation and those stations only which need service to inform the masterstation as to the details of the needed service. The many message exchanges between the master station and individual stations needing nothing is eliminated.

Abstract: A broadband data communication system provides effective increased bandwidth for the transmission of electrical information signals in the system. The signal transmission medium is a coaxial cable having main receive and transmit branches, and having drop line pairs connected to the main branches at junction points. A plurality of user devices is connected to each drop line pair, including a particular set connected to a particular pair. Each user device of the set can transmit and receive signals of local frequencies in a selected bandwidth. Frequency isolation means is connected to the particular drop line pair adjacent its junction point, and passes signals of the local frequencies only from the transmit drop line to the receive drop line, while blocking signals of the local frequencies from transmission over the main cable branches. The particular set of user devices and the filter isolation means together define a subnet.

Abstract: A circuit for detecting dial pulses at a receiving telephone transmitted from a sending telephone after the telephones are interconnected. Detecting circuits, including bandpass filters and summing and threshold circuits transmit a probable pulse signal. A probable pulse signal indicates that the signals on the telephone line have the characteristics present whenever the dialing mechanism at the sending telephone is actuated. A digital correlation circuit receives all the probable pulse signals and advances a counter which stores the number representing the dialed digit if a correlation exists.
