Abstract: A currency cassette (10) has a printed circuit board (80) secured to one of its side walls, the board (80) having mounted thereon a microprocessor, a RAM, a real time clock chip, and battery means for supplying power for the board (80). First (208) and second switches are respectively operatively associated with the lid (14) of the cassette (10) and with a shutter which, when opened, permits currency notes to be extracted in operation from the cassette (10). Opening of the lid (14) or the shutter causes the appropriate switch to be actuated. Each switch is connected to the printed circuit board (80), and the microprocessor is arranged, in response to actuation of either of the switches, to store in the RAM data indicating which switch was actuated and the date and time of day when the relevant switch was actuated. The switches and printed circuit board (80) provide an effective tamper indicating system for the cassette (10).

Abstract: A video display controller for controlling the display of characters stored in a bit plane memory. The characters to be displayed are arranged in the bit plane memory in a set number of scan lines with a set number of data bits in each scan line. Attribute bits are included in one scan line of data bits in each character to be displayed. The controller includes a data bus for receiving data from the bit memory plane in bytes, each of which includes data bits of one scan line. Each data byte from the data bus is clocked into a shift register, with the data byte shifted out of the shift register sequentially, one bit at a time. Attribute bytes are selected from the data bus and an attribute logic circuit applies the attribute bits to the sequential data bits of a corresponding character to be displayed.

Abstract: The present circuit incorporates a latch which latches an asynchronous input signal and provides a latched output signal to the first stage of a two stage synchronizer. An AND gate receives the latched output signal and the output from the first stage such that the output signal from the AND gate follows the output of the first synchronizer and is presented as an input to a second stage of the two stage synchronizer. The second stage is clocked, as is the first stage, with the system clock signal to provide the synchronized output signal. An asynchronous reset of the latch causes the output of the AND gate to go low which in turn causes the output of the second stage to go low asynchronously.

Abstract: A scanning system having a motor-driven scanning element automatically shuts down a scanning laser when the motor is either inoperative or operating below a safe speed. A microprocessor already used to drive the scanning circuitry is also used to control the operation of the motor, including commutation logic, and also controls the automatic laser shut-down. This results in a significant reduction of power requirement.

Abstract: A method and apparatus for applying a correction sticker to a document to cover incorrect data entered on a field on the document. Correction stickers on a carrier strip are fed to an application station where a document whose field to be covered is located. An ejector plate and a pressure plate located at the application station are used to partially separate a correction sticker from the carrier and to position the leading edge of the correction sticker in an application position with regard to the field on the document to be covered. An operating lever having a roller on one end thereof is used to move the leading edge of the correction sticker into adherence with the document. The roller is then held in contact with the correction sticker as the document is pulled out of the application station to press the remaining portion of the correction sticker into adherence with the field on the document.

Abstract: In a digital data receiver (80) for demodulating a direct sequence spread spectrum differential phase shift keyed data signal, the signal is applied to the input transducer (140) of a SAW device (100) which has first and second output transducers (142, 144) spaced apart on the SAW substrate (130) so as to produce first and second output signals on output lines (102, 104), which are relatively delayed by a time corresponding to a symbol period. The output transducers are of identical construction and are matched to the spread spectrum code utilized in the data signal. Thus, a single SAW device (100) effects both correlation and delay. The output signals on the output lines (102, 104) are processed by a circuit including multipliers (106, 110) and a phase shifter (108) to produce output data signals representing the received data.

Abstract: A despository apparatus for stacking envelopes in a container (24) includes a transport (16) for conveying an envelope (122') from an entry slot (22) of the apparatus into a receiving zone of the container (24), the receiving zone being separated from a storage zone of the container (24) by resiliently mounted flaps which in operation permit one-way passage of an envelope from the receiving zone into the storage zone. A pusher block (146) is arranged to push an envelope in the receiving zone past the flaps and into the storage zone against the pressure exerted by a block of elastomeric material held in the storage zone in a somewhat compressed condition. For the purpose of simplifying the construction of the apparatus, there is employed a single bidirectional electric motor (80) for driving the transport (16) when operating in one sense, and for driving an actuator (108) for the pusher block (146) when operating in the opposite sense.

Abstract: The structure of a pair of concentrically disposed field effect transistors responsive to a common gate electrode, and a process for the fabrication thereof. In one form, a dielectric region is surrounded by an active region of monocrystalline silicon and has situated upon the dielectric region a layer of recrystallized silicon as a second active region. A gate electrode overlies both active regions and serves as a mask to form in such respective regions self-aligned channels. The concentric placement of the active substrate monocrystalline silicon region, and inner perimeter of dielectric, and a further inner active region of recrystallized silicon situated over a dielectric region, facilitates recrystallization from seed of monocrystalline silicon irrespective of the direction of translation taken by the energy beam, and associated melt, in scanning across the structure.

Abstract: An interlocking base for use with stacked interlocking electronic assemblies which increases the mechanical stability of the base-stack combination. The increased stability allows a stack of up to four electronics assemblies to be subjected to an inclination of 15 degrees from the vertical in any direction without falling over. The base is furnished with an AC power cord and an ON/OFF AC power switch to provide single switch control of the ACs power conducted to the electronic assemblies of the stack. Single switch control saves operator time and motion, and also prevents accidentally leaving one of the assemblies of the stack ON while turning all the others OFF at the completion of work.

Abstract: A passbook page turning mechanism includes independently movable and spaced upper rollers and independently movable and spaced lower rollers which are vertically movable and which grip the passbook and move the passbook from a printing station to a page turning station. A pair of upper and lower longitudinally movable rollers serve as apparatus to turn the pages of the passbook. At the page turning station, a lower roller of the pair of rollers is raised to flex the passbook and an upper roller of the pair of rollers is rotated to turn the page and to complete the page turning operation after which the passbook is moved to the printing station. The lower roller of the pair of rollers is also displaceable in the longitudinal direction from the upper roller of the pair of rollers. The mechanism also provides for turning one or more pages in the opposite direction from the direction of a normal page turning operation.
