An electronic switch circuit and a pulse generator are connected in series between a positive and a negative power line. The switch circuit is, once triggered, rendered conductive and retains its conductive condition as long as left alone. The pulse generator automatically renders the conductive switch circuit non-conductive at a preset later time. An output can be derived in the form of a pulse from the pulse generator only while the switch circuit is conductive.

A circuit provides multiple output switching functions. Diodes couple groups of switching elements to form a single complex circuit. The diodes provide isolation between each group so that the logical function of each group may be output, as well as the logical function provided by the coaction of the groups. The present invention is particularly useful in circuits using complementary switching elements, e.g., Complementary Metal Oxide Semiconductor (CMOS) and Silicon on Sapphire (SOS) integrate...

Infinitely-variable transmissions have been disclosed that consist of a plurality of inverted-gear-train-loops that share common first and last gear elements with each individual loop incorporating a square-wave-generator, with the first and last common elements of the loops being respectively either the variable-ratio-driver-gears of the generators, or the driven-take-off-gear of the loops, with the differential-assemblies of the generators mounted in a stationary-housing with their axies paral...

An output speed-controlled transmission comprising an input shaft, an output shaft and adjustable drive means through which said input shaft drives said output shaft.

A sequence of light emitting diodes are progressively illuminated with progressively increasing instantaneous amplifier output signal amplitude with the last pair of light emitting diodes illuminated simultaneously to indicate amplifier clipping.

A monitor for detecting faults in the output signals of a transmitter in which a selected modulation component of the signal is used to activate fault-detecting means. In the case of a DVOR beacon system, the sub-carrier frequency is filtered from the detected and amplified signal obtained by a monitor antenna and applied to a full-wave rectifier, and the fault detecting means responds to the absence of one or more of the unidirectional pulses thus produced.

Output circuitry for a digital instrument includes a counter providing a binary coded digital number which represents a measured value of an electrical parameter and which is periodically updated. The binary coded number in the counter is transferred to an output store in response to periodic transfer pulses. Control means are provided to reduce flicker in a digital display driven from the store by preventing the transfer of the least significant digit of the digital number from the counter to t...

A process controller having an output circuit with a grounded true voltage and current output supplied by a grounded source is provided by using a differential amplifier as an output amplifier driving a transistor so that its emitter-collector path carries an output current from a grounded source through a dropping resistor and the current output. Another differential amplifier with negative feedback is connected across the dropping resistor by a resistance network so that it compares a fraction...

An output-voltage variable device utilizing a metal oxide semiconductor field-effect transistor is disclosed. A single pole double throw center off switch whose movable contact arm is connected to the gate of the field-effect transistor has its fixed contacts connected to a positive and negative power supplies, and a non-polarized capacitor is inserted between the gate of the field-effect transistor and ground. When the capacitor is charged with the positive charge, the output voltage derived fr...
