A system for storing and deploying a number of elements sequentially in connected but spaced-apart relationship is described. Adjacent elements are joined together temporarily by connectors which overlay adjacent elements. The connectors are bound to the elements by a plurality of cables, one of which is wound around each element and the overlying connectors. One end of each cable is connected to the element around which it is wound and the other end is connected to the next preceding element. W...

An acoustic transducer provides an elongated outer shell made of magnetic material and having a pair of flexural members attached to each other in the elongated direction and having a flexural portion extending normally to the elongated direction and forming a partial enclosure between the two flexural portions, and a magnetic drive located within the partial enclosure and engaging the flexural portions for causing the portions to oscillate flexurally.

A monolithic integrated circuit power sensor provides a monolithic integrated circuit substrate, a conversion element formed either on or in the substrate for converting microwave energy into heat, and a thermally sensitive diode junction formed in sufficiently close proximity to the conversion element to be thermally coupled thereto.

In order to sense the presence of sound in a remote underwater location, a neutrally buoyant reflector (20) is deployed underwater, and a laser (12) disposed at a remote location aims coherent light at the reflector (20). A detector (24) senses the coherent light reflected from the reflector (20) and compares it in phase with coherent light split from the outgoing beam. The system then provides an indication of the presence of sound by, for instance, amplifying the result of the phase detection ...

An apparatus and method for measuring the frequencies of a pair of signals simultaneously present in a composite signal, comprising the steps of includes components for squaring the composite signal, filtering the squared signal for separating a first pass band and a higher frequency second pass band, instantaneously measuring the frequencies of the first and second pass bands and determining the individual frequencies of the pair of signals from the measured frequencies of the first and second ...

A magnetometer is desclosed in which a gas cell containing atomic vapor is pulse pumped at one of the transitions of the gas in the cell. After the pulse has passed through the gas cell, thereby causing alignment of all the individual atomic moments along the propagation direction of the pulse, a probe beam reads out the Larmor precession frequency of the freely precessing atoms in terms of the frequency of the amplitude modulation of the probe beam caused by the free precession within the gas c...

A semiconductor device is provided of the type having a doped semiconductor region coupled to source and drain electrodes and an elongated control gate contacting the doped region along the length of the gate for forming a nonconducting depletion region across the doped region for preventing current flow therethrough with the gate having a minimized width to reduce contact area with the doped region, wherein the width of the gate is repeatedly reduced along the length thereof for further reducin...

A monolithic microwave integrated circuit device provides a microwave transmission line with a resistor coupled thereto and a heating element thermally coupled to the resistor but electrically insulated therefrom by a dielectric layer. Heating the resistor with the heating element causes either a change in resistance of the resistor or the generation of noise by the resistor. Either the resistor or the heating element is constructed using monolithic integrated circuit construction techniques on ...

An apparatus for transforming a voice signal of a talker into a voice signal having characteristics of a different person provides apparatus for separating the talker's voice signal into a plurality of voice parameters including frequency components, a neural network for transforming at least some of the separated frequency components into those characteristic of the different person, and apparatus for combining the voice parameters for reconstituting the talker's voice signal having characteris...

Apparatus for determining position within a beam, comprising pulses of energy transmitted in coded patterns, is achieved by processing the signals received from the beam to generate a value indicative of coarse position within the beam and by interpolation within the coarse position to generate a value resolving fine position within the coarse position.
