Abstract: A method and apparatus for manually and automatically accessing a plurality of data records in a large scale data array, comprising placing alphanumeric and other visually distinctive indicia on the exposed surface of the data records to be manually accessed; displaying a list of data records to be accessed; issuing a command to a drive controller to indicate the desired documents and data records to be accessed; determining that a desired data record is in a data drive; automatically transferring the desired documents between the drive and a buffer; ejecting the data record from the drive or otherwise indicating to the operator that the transfer is complete; and updating the displayed list of data records to remove those that have already been accessed; all without requiring an operator to input any keyboard information during the accessing cycle.

Abstract: In a bidirectional communication channel, the method and apparatus for determining directionality of communication signals using digital techniques. A plurality of independent signals are derived from the communication channel, which signals are analyzed to determine their relative phase(s). The relative phase(s) are then compared with a table of relative phases indicating the directionality of the original signals.

Abstract: Subscriber's interface enabling the connection of otherwise incompatible telephone device systems (hereinafter "(Z)") to a single telephone line, each telephone device system having devices such as: a computer modem (hereinafter "(F)"), an automatic answering machine (hereinafter "(A)"), and telephone sets (hereinafter "(T)"). When a ring signal is received from the central office, the interface allows a first device, such as (A) or (T) to answer the call, and monitors the communication between the calling party and the first device bearing in mind its various operating modes. Based on the monitored conversation, the interface determines if the call should be connected to a second device, such as (F). If so, an actuating signal is sent to (F), whereupon when (F) becomes OFF HOOK, it is connected to the telephone line. If the first device is an automatic answering machine, its various operating modes include: outgoing message, incoming message, beeperless remote mode.

Abstract: An image sensor having image sensing cells of extreme sensitivity, wherein, in a preferred embodiment, each cell has at least one pair of cross-coupled current control elements that provide regenerative feedback so that microscopic image influences will be continuously magnified until they become sufficiently large for sensing. The continuous magnification is allowed to take place only at a controlled rate and during a controlled time, thereby causing a controlled degree of magnification of the image signal to be developed within each cell.

Abstract: In a conventional imaging system wherein there exists a tendency for portions of the system elements to be defective, the image is shifted relative to the image sensing elements prior to scanning the elements so that the defective portions of the system will be associated with different portions of the image during at least two scans. Correction circuitry provides an image signal which is compensated for the defective portions and for the shifted image.
