Abstract: A programmable computerized telephone cost metering device which gives a visual display of the cost (per unit of time) of a call before the user completes dialing his intended number, total cost of call in progress, and total of costs for day or month. Metering device may be programmed for user's telephone exchange and type of service he has contacted with his telephone company, and programing may be inputted and updated by any of several methods including: direct user inputting of information, insertion of an EPROM chip, voice recognition device, and an automatic inputting of data from a remote data bank by means of a built in MODEM. Security of access is assured by use of user programmed access code. The metering device may contain a built in telephone or may be used with existing telephone instruments.

Abstract: A method for displaying characters on a raster display including the steps of storing a digitized font of normalized encoded characters in a first store, storing the identity size, and display location of the characters in a second store, generating a succession of raster lines, 1 through N, said first raster line being 1 and said last raster line being N in a predetermined order of raster lines, arranging successive characters in said second store into segments, each segment referenced to a respective raster line 1 through N, reordering the sequence of said segments by the value of each segment's respective raster line 1 through N, sequentially identifying respective segments for successively generated raster lines, identifying the boundaries of the characters within the said segments intersecting the raster lines and displaying the said characters responsive to said identified intersections.

Abstract: A digital typesetter for imaging graphics quality characters of a specified font. The typesetter includes an electronic data processing system which receives first digital data defining the identity, form, size and placement of characters to be typeset; receives second digital data defining the contour of each character to be typeset with respect to a normalized encoding set of first and second coordinates; and produces third digital data defining the character boundaries intersecting a raster (scan) line. This third digital data, for at least a portion of the raster line extending the width of several characters, is temporarily stored in a raster line storage buffer. A character imaging device, connected to the line storage buffer, is provided to image successive raster lines on a print medium. Drive means are also provided for moving the print medium in a direction transverse to the direction of the raster (scan) line.
