Abstract: An integrated circuit-based charge pump generates an output voltage having a greater magnitude than a power supply voltage. The charge pump has a charge pump section having a plurality of alternating stages driven by first and second alternating, non-overlapping clock signals, said plurality of alternating stages including an input stage for receiving the power supply voltage and an output stage for generating at a last stage node a last stage voltage having a greater magnitude than the power supply voltage. A gating transistor is coupled at a drain terminal to the last stage node, wherein the gating transistor is clocked by one of said clock signals and is biased so that the gating transistor, during a boost phase, gates the last stage voltage to a load coupled to the source terminal of the gating transistor without a voltage drop and, at other times, turns off to prevent charge from flowing from the load into the last stage node of the charge pump section.

Abstract: The present invention provides a body cooling garment to easily and effectively cool the human body. By pressurizing air or other compressible gases to a minimum pressure rating of 70 psi and channeling it by means of a tubing network that is incorporated into body garments such as vest, head covers, and pants, the pressurized air can be transported and dispensed on the individual. Thus a two fold cooling affect is accomplished. First, initial cooling is achieved by the cooling of the pressurized gas itself as it rapidly depressurizes and expands though openings in the tubing resulting is a very cold gas. This affect combined with the flow of air and gases that is created by this expansion of pressurized gas in the vicinity of the body of an individual wearing such a garment will evaporatively cool the body and compliment the cooling caused by the rapid depressurization of the compressed gas.

Abstract: A ground electrode is formed on the back surface of a dielectric substrate, while a high-frequency element consisting of a diode or a transistor and signal lines conducting with the high-frequency element are formed on the front surface thereof. Striplines are formed to extend from intermediate portions of the signal lines, while capacitor electrodes having constant surface areas are formed on nodes between the signal lines and the striplines respectively.

Abstract: A remotely controlled actuator assembly is provided to switch a large power distribution switch used in an electrical utility power grid. The actuator of the assembly throws the switch between at least two positions to establish at least two power routing conditions. The actuator assembly includes a position-sensing device to repeatably and accurately indicate the position of the actuator. The position-sensing device generates a signal indicative of the extent of displacement of the actuator. The generated signal provides feed-back to a control system which control the extent of actuator travel.

Abstract: A semiconductor integrated circuit device is provided with an input and/or an output terminal and at least one semiconductor device. The circuit has a resistor provided between the input terminal and/or the output terminal and one of the at least one semiconductor devices and an electronic switch connected in parallel with the resistor. The electronic switch is on-off controlled so as to exhibit a relatively low impedance when the semiconductor device is in operation and a relatively high impedance when the semiconductor device is not in operation. Thus, the semiconductor integrated circuit device is operable at a higher speed with an improved reliability and/or with controllable response characteristics, as compared with the conventional device.

Abstract: A DC voltage source of amplitude below the DC voltage requirement of a load to be energized drives a pair of complementary transistors which are alternately turned on and off to apply supply voltage alternately to each of two capacitors connected in series. The sum voltage of the two capacitors is applied, in one embodiment, directly to a voltage regulator and filtered and, in another embodiment, is added to the DC source voltage prior to being regulated and filtered. The converter output is capacitively coupled to the DC supply voltage, thus furnishing a common AC connection.
