Inventor: GROVER DAVID N
IPC: H04N1/41
Filed: 1984-03-12
Abstract: An apparatus codes a scanned document locally representing each graphic element within a prescribed mesure of accuracy by a trapezoidal approximation. The invention also includes a method for similarly coding a scanned document. The apparatus determines whether each scanned run is indicative of a Y- or λ-junction, the termination of an old, or the commencement of a new graphic element, and whether a new linear approximation is necessary. The invention is preferred embodiment recognizes symbols by determining the center of mass and maximum extremity of a symbol candidate, and comparing it to a reference library after normalizing with respect to scale, orientation and center of mass. in a preferred embodiment, an adaptive threshold parameter governs coding so as to reject noise and optimize a pair of linear predicters in a small number of scans. In a further preferred embodiment the accuracy of the linear predicters is refined so that the error is exponentially bounded.

Patent EP-0137928-A2 (EP)
Inventor: SACHS MARTIN WILLIAM
IPC: H04L1/12
Filed: 1984-07-24
Abstract: When two transceivers (12,14) communicate with each other, the one transceiver may operate at a different internal speed with respect to the other transceiver. In addition, one transceiver may possess different buffering capabilities with respect to the other transceiver. As a result, when one transceiver attempts to communicate with the other transceiver, the more powerful transceiver may overload the other transceiver. This is avoided in the disclosed system and method in which, prior to the initiation of a data transmission, the two transceivers exchange count and rate information. Count information designates the maximum number of bytes of data which the transceiver can receive within a single data frame. Rate information designates the maximum rate at which the transceiver can receive data frames. When the exchange of count and rate information is completed, data transmission will take place using the smaller of the two counts, and the smaller of the two rates.

Abstract: An integrated circuit shift register comprising regions (11,13,15 and 17) of n type semiconductor material formed by diffusion in a p- type epitaxy (3) formed on a substrate (5). Overlying each region (11,13,15 and 17) is a shallow diffusion of p type material (19,21,23 and 25), each provided with a projection (27,29,31 and 33) overlying the epitaxy material (3) between the regions (11,13,15 and 17) of n type semiconductor material. The regions of n type semiconductor material (11,13,15 and 17) each form common emitter and collector regions of adjacent bipolar lateral transistors in a series, the projections (27,29,31 and 33) form base contacts and the region of overlap between the shallow diffusions of p type material (19,21,23 and 25) and the regions of n type material (11,13,15 and 17) form a capacitor in the form of a reversed biased PN junction. A clocking pulse applied sequentially to the shallow diffusions of p type material causes movement through the shift register of data stored as voltages in the reverse biased PN junction. The clocking pulse sets up a potential gradient in the epitaxy (3) which restricts unwanted carrier injection into the substrate.
