Abstract:
The fluid logic controlled elastic diaphragm switch matrix is formed of multiple elastic diaphragms having conductive surface portions in alignment with apertures carried by interspersed rigid sheets with the central elastic diaphragm carrying opposed and insulated conducting surfaces which are grounded when the switch point is open to act as shields. The matrix coordinate input pulses are amplified at each matrix unit to verify proper operation of the switch actuating fluid amplifier.
Abstract:
An improvement in binary adder circuits based on a new Boolean algorithm is disclosed. The arrangement permits calculation of the carry from the logical combination of the addend, the EXCLUSIVE OR of the addend and the augend, and the carry of the next preceding stage. The circuit is readily implemented in NOR logic and has particular application in large scale integrated circuits (LSI).
Abstract:
An information system which may be employed as a voice answer back system for assembling and transmitting separate messages on separate output lines. The basic components of the system are a rotating, fixed head sequential memory file, an associative memory, and a group of buffer storage units. Address keys for the words of the messages are obtained from a central processing unit. The rotating memory contains the entire file of message words stored in equal length segments of digital signals and each are identified by a key address. Message words may consist of a number of segments, each having the same key address and further identified by consecutive segment numbers. As the sequential memory is rotated, the key addresses of the segments are compared with the key addresses in the associative memory; and when matches occur, the segments are retained in buffer storages. As each segment of a key address is obtained, the segment is transferred to the output of the system.
