Abstract: A data input device for use in an electrically noisy environment incorporates a plurality of conductive strips, arranged in rows and columns, mounted on a transparent body in front of a display device. Electrical noise is induced constantly in the conductive strips. When an operator places his finger in close association with one or more of the rows and columns, the amplitude of the electrical noise on such strips changes markedly. The change in noise level is detected and used to provide an output identifying the row and/or column in the vicinity of the operator's finger.

Abstract: An elevator mechanism for an automatic teller machine, equipped with a plurality of bill dispensing modules for dispensing bills at a plurality of elevations, incorporates a tray adapted to be raised and lowered by drive apparatus, the tray being rotatably mounted on a bracket and adapted to normally assume a horizontal position during its upward motion, during which it collects bills dispensed from the bill dispensing modules, an access door located at the top of the elevator assembly and an assembly for unlocking and lifting the door as the tray reaches its upper position. The tray is tilted during its downward movement so that any remaining contents of the tray are deposited into an escrow compartment.

Abstract: A control unit for supervising operation of data transmission to and from a data storage device such as a disk storage device, has a stored program for the unit, and a random access memory sufficient to store an entire block of data received from the data storage device. In one arrangement, the control unit works in conjunction with external data processing apparatus, and the control unit controls interchange of data between the data processing apparatus and the data storage device. The external data processing apparatus has a reduced memory capacity requirement, because of the control unit, and delays caused by static timing requirements are minimized. When the data storage device is a disk storage device, reading is performed without delay, using the first available sector of the disk in a given track.

Abstract: In a dispensing machine, a magazine is provided in which a multiplicity of packets to be dispensed are maintained in a magazine supported by clips which support the packets on a helical screw. The packets are dispensed individually by energizing a motor to turn the screw, during which the endmost packet drops into a receiving tray. The drop of the packet is detected by a photosensitive detector, and the screw driving motor is deenergized. The magazine contains a channel for maintaining the packets in single-file relationship as they are advanced toward the end of the screw in response to rotation of the screw. The tray into which the packets are dropped is slidable between an inner position, in which it is disposed below the dispensing magazine, and an outer position in which the contents of the tray are accessible to an operator. The tray is forced toward an outer position, and a motorized drive is provided for moving the tray backwardly and forwardly when the tray is in a rearward position.
