US Classification:

379204

Abstract:

The teleconferencing system includes three or more audiographic teleconferencing terminals where any one of the terminals can act as a sending terminal and/or a receiving terminal during a teleconferencing session. Each terminal includes means for establishing a broadcast and listen protocol that permits a sending terminal to transmit a facsimile image to multiple receiver terminals simultaneously.

Appl. No.:

7/729648

Assignee:

Nynex Corporation - New York NY

International Classification:

G06F 1520
G06K 1906

US Classification:

235375

Abstract:

A system which utilizes a bar code having an instruction field whose data specifies an action to be performed and also having a reference field whose data relates to the data in the instruction field. The system reads the instruction and reference fields of the bar code and processess the read data. This processing may determine from the instruction field data that the action or actions to be taken are to be taken on data other than that in the reference field of the bar code. It also may determine from the data in the instruction field that an action to be taken on the data in the reference field is other than an action identified in the instruction field of the bar code. Based on these determinations, the system continues the processing using the appropriate action and data. A unique bar is also used in the system. This bar code, between its start and stop fields, has a separator field whose width is greater than that of any of the individual bar code characters.

Abstract:

A method and system for reproducing halftone originals utilizing threshold gray level values of the scanned pixels of the halftone original to determine adjacent pairs of pixels bordering the edges of the halftone dots. Edge errors for the adjacent pairs of pixels are determined using the scanned gray level values and a threshold value. A processing window defines sub-arrays of pixels whose thresholded gray level values are processed based on the edge errors. For each sub-array, the edge errors of the adjacent pairs of pixels are summed. The thresholded values of the adjacent pairs of pixels are then selectively changed in the order of pixel pairs of descending edge error until the number of values changed equals the closest integer to the summed edge error.
