Abstract: A multifunction arithmetic indicator that is associated with and controlled by an arithmetic logic unit (ALU) to store standard arithmetic indicator information such as overflow, carry, arithmetic sign and all bits equal zero that are generated by the ALU when processing binary information. A control unit sends control signals to multiplexers in the multifunction arithmetic indicator that cause the selection of appropriate arithmetic indicator information from the ALU, no matter what the bit length of binary words being processed by the ALU. The selected indicator information is stored in a register for later use.

Abstract: Memory failure detection apparatus is disclosed which is used with a large capacity memory that is organized in banks of memory, and with which error correction circuitry is used to correct correctable errors and provide an indication of same. The detection apparatus is responsive to the error indications and to a bank select addressing signal to provide and store error counts for a bank or banks of memory located on each memory board. A system processor periodically reads the error counts and responds to same to provide a maintenance message indicating that a specific memory board is to be replaced.

Abstract: A pencil for electrosurgical generators includes a push button switch structure useful in selectively bridging spaced printed circuit contacts in spite of oxidized film on the contact surface. A movable concave disk has a sharp peripheral edge that is forced against the contact surface during switch actuation to cut through the oxidized film and reliably bridge the contacts. The disk is carried by an axial projection forming part of a resilient dome surrounding the projection. The dome includes a radial flange which is compressed against the printed circuit board by an annular member projecting axially inwardly from the housing wall around the outside of the dome. The closed end of the dome is connected to the flange by a frusto-conical connecting wall adapted to flex to permit the closed dome end to be pushed toward the open dome end during switch actuation.

Abstract: A method and system of selecting items of data from a stream of information by comparing the information to reference data. The reference data items are recorded in the form of logical entities in a two dimensional memory table. The reference logical entities of different types are stored vertically in different horizontal zones of the table in the order in which the entities of the same type are found in the file. In a control memory are stored, line-by-line, control information which specify the comparisons to be made between the reference logical entities and logical entities which are received from the file, as well as control information related to storage of logical entities received from the file and of operations including comparisons and storage between comparison results and other data contained in the table and information related to the linkage of processes for each control line of the control memory or from one control line to another.

Abstract: The present invention relates to a method which uses results from comparisons, to permute data sources into read-out and/or into read-in for restarting or storage the information. Comparisons are made between data which does not necessarily issue from the same stream of information which is stored in buffer stores and compared on computing units for two data from different sources or on computing units for two data from the same source. The reference data are respectively stored in columns in reference tables. Simultaneously, the datum is recorded on one or more other columns of the tables to serve as references for the comparisons on a datum issuing from the same or different streams of information. The result of the comparisons permutes by a decoder the sources into read-out and/or into read-in, the columns of reference tables into read-out and into read-in and the corresponding computing units.
