Abstract: A unique new group of “Faux-Sateen, Quasi-Unidirectional(UD)” woven anti-ballistic fabrics is disclosed. Novel and unexpected improvements in ballistic penetration resistance result. After appropriate lamination of at least two layers, ballistic resistance is either maintained or further enhanced, while blunt trauma resistance is improved. Fabric handling during vest fabrication is also greatly improved and significantly less stitching is required. Wearability is also improved.

Abstract: Molded body armor panels conformed to fit individual torsos based upon gender or, in custom applications, individual features of a particular male or female torso. The individual body panels are constructed of multiple layers of twill or other unconventional long float woven ballistic fibers with each layer impregnated with a curable adhesive. Additional reinforcement may be supplied in appropriate areas, such as breasts, spine, sternum and edges. The multiple impregnated layers of fabric are placed within a mold conforming to the particular torso contour desired. The long floats of the fabric allows the layers to stretch or compress as required to the particular shape desired. The adhesive is cured in the mold under low heat and low pressure, binding the layers of fabric together, as well as binding the conformed yarns of each individual layer in permanent contour. Interior and exterior coverings for comfort and appearance may be supplied.

Abstract: A method for improving the etch uniformity of features of a device and etch profiles for devices made, for example, by deep reactive ion etching, by patterning sacrificial features or devices adjacent target features or devices. The method for providing etch depth uniformity for plasma etching, includes adding sacrificial features to a substrate containing a plurality of target features, etching the sacrificial and target features and separating the substrate into a plurality of pieces, wherein at least one piece contains at least one target feature.

Abstract: A system and method for localizing an aggregated electronic program guide (EPG) schedule covering a plurality of service environments includes an information filter located at the subscriber's set-top box conditioned to recognize which schedule information is relevant to the viewer's service environment. Only schedule information corresponding to the viewer's own service environment is stored in the EPG's schedule database. The result is an electronic program schedule that is tailored to the viewer's specific service environment without the use of costly equipment on the transmission side of the program schedule feed.

Abstract: An audio frequency (AF) track circuit whereby a railway track tuned loop transmitter operating in a dual resonant mode, for handling, two signal frequencies, can be coupled to the rails. Each frequency is conducted through a tuning unit having series and parallel branches tuned to each frequency. The track circuit using the tuned loop transmitter eliminates DC return current imbalance effects while maintaining suitably high track circuit shunting sensitivity.

Abstract: Coin apparatus for use in a manually operable vending machine which has latches for locking it against operation unless coin sufficient for purchase of an item is deposited, the apparatus having electronically controlled latch release members operable on manual operation of the vending machine, following deposit of a sufficient amount in nickels, dimes and quarters for a vend, to release the latches. The nickels, dimes and quarters drop through nickel, dime and quarter chutes, quarters being sensed by interception of a first beam of light, dimes by interception of a second beam of light, and nickels by interception of both beams. An escrow system includes a gate which opens on a vend to allow escrowed coins to drop out for delivery to a money box, provision being made for holding this gate open for a time sufficient for dropout of all escrowed coins.

Abstract: Coin apparatus for use in a vendor for handling acceptable coins and unacceptable coins or slugs deposited in the vendor, having change tubes for coins of different denominations, and operable to reject unacceptable coins and slugs, to accept acceptable coins and to deliver them as needed to the change tubes and, when not needed in the change tubes, to escrow them, to deliver coins from escrow to the cash box of the vendor upon a vend and to the coin return system of the vendor on recall of a deposit by a customer, to deliver coins from the change tubes on a recall in the same number and denomination as those deposited by the customer in the vendor and delivered to the change tubes, and to make change from the change tubes as needed on a vend.

Abstract: A railroad train detector and communication system relies on the track rails for communicating information among a plurality of locations. The equipment located at each of the locations eliminates relay based current detection, relay based current transmission, and relay based logic functions, and rather these functions are implemented with microprocessors. An extent of signal trackway is defined between a pair of head ends, intermediate the head ends at intermediate insulated joint locations, a microprocessor implemented transmitter/receiver pair is provided. One half of the transmitter/receiver pair manages communication flow for each direction of information flow at the joint. At each of the head locations, only a single transmitter/receiver is required. Associated with each microprocessor in a transmitter/receiver is auxiliary apparatus to couple the microprocessor's input/output ports to the track rails themselves.

Abstract: A receiver for sensing track currents includes a toroid coupled to the track rails via a single conductor. The toroid has an air gap in which a linear Hall sensor is inserted. The voltage of the Hall sensor is applied to signal processing circuitry including a low pass filter, amplifier and level detectors. In one embodiment of the invention comprising a track occupancy detector, second and third windings coupled to the toroid are selectively energized from a potential source to provide MMF's in the toroid of one and another polarity, and of a level less than the MMF provided by an occupied track section. The amplifier includes first and second channels for amplifying signals of opposite polarities. Each channel of the amplifier is coupled to a pair of level detectors, one of the level detectors in each pair is a vital level detector with the threshold set at about 50% of the threshold of the other level detector in the pair.

Abstract: An audio frequency track circuit with improved security in the train detection function for rapid transit applications for use with uninsulated rails includes an improved transmitter and receiver. The transmitter modulates a track frequency carrier with a fixed code rate, regardless of the code rate employed to modulate the train information frequency. The receiver includes a decoder tuned to the track frequency modulation rate. By using such a sharply tuned decoder, the noise protection threshold is increased. Because of its application to uninsulated rails, with the associated lack of hard track circuit boundaries, adjacent track circuits have different track frequency modulation rates to insure that the modulated track frequency signal, from one track circuit, is not effective to operate a track relay in another circuit even under failure conditions.

Abstract: Coin dispensing apparatus comprising a base having a socket therein adjacent one end of the base constituting its rearward end, a coin ejector at the bottom of the socket movable forward away from a retracted position for ejecting a coin in the socket, the ejector being movable forward to eject the coin and rearward back to a retracted position. The socket is adapted to receive a coin tube for holding a stack of coins, the bottom coin bearing on the bottom of the socket. The socket has an exit passage at the forward end for ejection of the coin by sliding it forward off the bottom of the socket. The bottom of the socket has a forward edge and an opening adjacent the rearward side of the socket. A central slot extends in the bottom of the socket between its opening and the forward edge. The ejector comprises a U-shaped member opening toward the forward end of the base and has an upstanding T-shaped projection at a central portion of its closed end.

Abstract: A track circuit signalling system for an electrified rapid transit system using significantly fewer components is provided. Instead of a transmitter and receiver at each track circuit boundary, alternate boundaries have transmitters only; and the intermediate boundaries have two receivers. The coupling units for the two receivers are more economical than the prior art coupling unit for coupling the transmitter-receiver combination. The transmitters on each side of a receiver pair transmit signals on different carrier frequencies. Each transmitter transmits in both directions from its location. Of the two receivers at a given boundary, one is tuned to respond to signals from the transmitter on one side, while the other receiver of the pair is tuned to respond to signals from the transmitter on the other side. For special applications using overlapping track circuits, selected transmitters may be omitted and a single receiver used on each side of the omitted transmitter.
