Abstract: A computer system is disclosed in which instruction sequencing is under the control of a program control computer, but each individual instruction is assigned for execution to an individual instruction computer. Each instruction computer includes programmable instruction decoding means by the modification of which the microtasks undertaken to execute an instruction are accordingly modifiable, either between successive execution cycles or during a single execution cycle. Thus, the system has the inherent ability to learn and adapt during the performance of a program. The system may be extended in two-dimensional and three-dimensional arrays to obtain a multiplication of power and to enjoy redundancy advantages.

Abstract: A floating gate cell memory device, such as an EPROM or flash EEPROM, with improved discharge speed. A negative bias is applied to the effective substrate during discharge. The negative bias increases the electric field near the junction, thereby increasing the number of hot holes which can be injected to the floating gate, improving discharge speed.

Abstract: A mechanically and electrically efficient, lightweight, portable motor-generator includes a stator having a plurality of windings and a rotor with a body of soft-magnetic material carrying a plurality of permanent, high energy product magnets in a surface near the stator such that relative motion of the rotor and stator causes magnetic flux from the permanent magnets to interact with and induce current in the stator windings. The magnets are mounted in insets formed in the rotor surface which includes portions between the insets to form respective consequence poles. The rotor is a hollow cylinder with the magnets mounted on an internal surface, and the stator is concentrically disposed within the cylinder. The stator includes first and second windings.

Abstract: A container closure system includes a plurality of equally circumferentially distributed pins extending outwardly from the tubular neck of the container near the opening. A detachable cap consists of nested inner and outer cap members. The inner cap member is dimensioned to receive the container neck and includes a plurality of sidewall openings for receiving the pins. The outer cap member has a plurality of locking wedges disposed on its inner surface. The inner and outer cap members are assembled so as to permit mutual rotation. Thus, when the cap is emplaced over the open end of the container, the pins are received in the openings to thereby inhibit mutual rotation between the inner cap member and the container. Then, a twist of the outer cap member in a clockwise direction brings the ramp portion of each locking wedge into engagement with one of the pins, thereby drawing the cap and the tubular member together to effect a secure closure.

Abstract: In order to optimally control the charging of a rechargeable battery of one or more cells to ensure that full and rapid charge is achieved without damaging the battery, a maximum safe value (or sequence of values during the charging process) for one or more charging parameters is determined during a test charge, and subsequent charges of the battery are performed without exceeding the predetermined maximum value(s) for the charging parameter(s). Among the charging parameters contemplated for use are: the charging voltage potential placed across the battery terminals, the charging current supplied to the battery, the temperature of the battery cell and internal pressure of the battery cell as well as rates of changes of the parameters.

Abstract: A support member for use in groups of three or more to support and sonically damp a speaker enclosure. Each support member includes an intermediate piece which is preferably generally conical, a resilient damper element disk overlaying the piece upper, larger end and a pin extending downwardly from the piece lower, smaller end. The dimensions of the three principal components are selected such that a speaker enclosure is supported just above a carpet with the pin extending down through the carpet, through any backing or pad beneath the carpet and to an underlying rigid floor, typically concrete. This serves to directly couple the speaker enclosure to the massive substructure. The diameter of the pin is preferably no more than about one-eighths inch in order to prevent significant damage to the carpet and underlying pad. Preferably, the resilient damper element is fabricated from a urethane-based polymer material which achieves controlled additional damping in the critical bass frequencies.

Abstract: A memory device, such as a flash EEPROM, has zero birds' beaks and vertically overlapping gates to facilitate high cell density in the EEPROM's core. During fabrication, a layer of field oxide is formed over the core. The active regions are exposed by etching through the layer of field oxide to form vertically walled cavities around the active regions. The tunnel oxide, floating gate, interpoly dielectric, and the control gate are formed within each cavity so that the floating gate overlaps the control gate along the vertical walls. As a result, capacitive coupling between the gates is maintained, yet the horizontal dimensions of the cell decrease. Similarly, the absence of birds' beaks facilitates higher cell density in the core.

Abstract: A single use protective barrier medical accessory serves to isolate a sphygmomanometer cuff from a patient whose blood pressure is to be taken in order to prevent contamination of the cuff by the patient's bodily fluids such as blood. The medical accessory constitutes an open ended tubular sleeve fabricated from readily foldable, fluid impervious material. Each open end is provided with an elastic band to snugly close around the patient's arm. In use, the tubular sleeve is introduced over a patient's arm and slid into position. A sphygmomanometer cuff is then fixed in place over the sleeve in the usual position on the patient's arm. Then, an upper portion of the sleeve is folded over to completely cover the sphygmomanometer cuff while permitting admission of a tube coupled to a bulb for pressurizing the cuff. After the patient's blood pressure has been taken, the upper portion is unfolded, the cuff is removed and the sleeve is removed and disposed of, preferably according to established procedures.

Abstract: A memory device, such as a flash EEPROM, employs a high energy implantation to form common source line, avoiding the necessity of self-aligned source etch processes. The use of the high energy implantation, and avoiding the etching process, provides for greater cell uniformity, and better V.sub.T distribution.

Abstract: A flash EEPROM having reduced column leakage current suitably includes cells with more uniform erase times arranged in an array. An intermediate n+ implant immediately following the DDI implant step suitably provides an enhanced doping profile in the tunneling region, which increases the rate at which F-N tunneling occurs to erase the cells, and which increases the uniformity of F-N tunneling rates among memory cells within the array. A thermal cycle drives the intermediate n+ implant deeper into the tunneling region. Alternatively, an n+ implant may be performed at a relatively large angle with respect to the semiconductor substrate, which improves the doping concentration in the tunneling region of the source.

Abstract: The PWM control scheme is illustrated in conjunction with a power distribution control circuit (30), wherein the duty cycle of converter (32) is suitably controlled by a number of feedback loops embodying various parameters, for example a voltage error signal, an average (e.g. RMS) value of the input voltage (Vin). Circuit (30) comprises a rectifying circuit (42), a converter circuit (32), for example an AC-DC converter, a capacitor (C), an oscillator and PWM circuit (44), an error signal (46), a multiplier circuit (48), a differencing amplifier (50), and a synthesizing circuit (52). Circuit (30) appears as a resistive load to the line for feed PWM, a fixed load, and a fixed RMS input voltage. To stabilize the output voltage (Vout), the pulse width signal (44a) applied to converter suitably varies in proportion to both changes in the RMS value of the input voltage and the output voltage.

Abstract: A memory device including an array of cells, where a reference current is generated by a predetermined number of reference cells disposed separate from the array of cells, the transconductance of such reference cells being equal to the transconductance of the cells of the array.

Abstract: A light emitting module is attached to one of a pair of separable U-shaped metal clamps that can fit around a weapon trigger guard. The clamps have recesses for retaining elastomeric inserts which contact the trigger guard. The inserts are of inexpensive glass-filled molded plastic rather than machined steel so that a greater variety can be provided at low cost and little value is lost by discarding those not needed for a particular weapon. The greater variety provides a better fit with little or no custom shaping and the elastomeric inserts are much easier to shape if an unusually contoured trigger guard is encountered. A slide switch passes through the clamp and is actuated by either a right or left handed user. The motion of the switch is transverse to the trigger guard and firing direction of the gun.
