Abstract: An all-optical polar transform device transforms an image in rectangular rdinates into an image in polar coordinates by reflecting an input image-containing beam from a series of suitably positioned reflective surfaces and finally transmits the beam out as an output beam containing the transformed image.

Abstract: An optical scanning device for mechanically scanning images at a high scan ate over a wide field of view and under low light conditions. The device comprises a first rotating reflecting means such as mirrors for intersecting an input beam of light in a first path and for redirecting the beam of light into a second path. A second rotating reflecting means intersects the second path and reflects the beam of light into a third path, onto a detecting device for detecting the presence of predetermined images in the beam of light. In order to reflect the light beams over an elliptical path the mirrors are mounted on rotating shafts at a slight angle from the perpendicular to the axis of the rotating shaft. The mirrors are rotated at varying speed relationships to each other and varying phase relationships to each other in order to produce a variety of scan patterns.

Abstract: A method for performing the addition of two N-bit binary numbers using palel neural networks. The value of a first register is converted and transferred into a second register in a mathematical fashion so as to add the numbers of the first register into the second register. When the first register contains all zeros then the desired sum is found in the second register.

Abstract: Fumes disposal systems used with existing engines are complex, induce pollution and cause engine malfunction to occur. The present fumes disposal system overcomes these problems by utilizing the heat from the engine exhaust to heat a tubular member and cause excessive oil droplets, carbon particles and fumes to burn. The flow of exhaust from the engine is used to dissipate the remaining crankcase fumes insuring that any concentration of fumes are purged with the exhaust. Furthermore, the system controls the pressure within the crankcase of the engine.

Abstract: The present invention includes an adjustable head set held in place on the back of a patient's head when the patient leans back against a chair head rest. The head set includes self-preparing disposable monitors that provide good contact with the patient's head without prior skin preparation. The monitors include a conductive tube containing conductive wires, the tips of which form a planar cushion surface for contacting thr patient's head through a caratinaceous layer of skin. The monitors are held in adjustable holders that allow the contact force to be adjusted. The adjustable holders are mounted in holder slots of head set springs where the slots also allow adjustment of the placement of the monitors. The springs can include hinges for rotatably adjusting placement of the monitors. The disposable monitors are filled with an electrolyte solution using a disposable applicator including a puncturable film, punctured by a monitor when the electrolyte solution is being applied.

Abstract: Incoherent optical processing techniques are shown which demonstrate image intensity normalization and contour enhancement. A new type of incoherent optical correlator which combines a model of the human neural system with an intensity image convolver. The processor's principal element is a Hughes liquid crystal light valve (LCLV). All components are commercially available and used without modification except for a liquid crystal television (LCLV). In operation the invention can be used as either a pre-processor to intensity normalize and edge enhance video scenes for use in pattern recognition applications or as a real-time pattern recognition device within itself, with the addition of an LCTV.

Abstract: A regulator is provided in which the bias which urges the unseating of the regulating valve is a piston having a plurality of radial working surfaces, each in its own separate pressure chamber. The chambers are connected to the inlet selectively, singly or in combination, by solenoid valves. The unseating of the regulating valve is opposed by the outlet pressure which works on the entire back side of the piston. In the preferred form a relationship exists between the relative sizes of the individual piston working surfaces so that all the possible outlet pressures attainable by the regulator are equispaced, all the way from 0 psig to the highest regulated pressure.

Abstract: A remote laser locator system for viewing a wide field of view and detecting the angular position of a remote laser. A laser beam directed toward the sensor from any position within a 90 degree circular field-of-view can be detected to a positional accuracy of less than 0.1 degree in a two-axis coordinate system. The system utilizes an inline or coaxial optical sensor having field-of-view (FOV) optics that compress the field-of-view. The compressed output from the FOV optics is directed through a polarizer and filter to a phase shifter. The phase shifter, a pair of birefringent crystals, encodes the angle of incidence of the laser beam as a phase shift between the two components of the polarized input beam. Subsequently, an analyzer such as a Wollaston prism decomposes the beam into two linear component beams. These component beams are processed through a second phase shifter and an analyzer pair which are rotated axially with respect to the first pair to provide four distinct component beams.

Abstract: A laser position sensor system for viewing a wide field of view for detecting the angular position of a remote laser. A laser beam directed toward the sensor from any position within a 90 degree circular field-of-view can be detected to a positional accuracy of less than 0.1 degree in a two-axis coordinate system. The system utilizes two parallel sensors having field-of-view optics that compress the field-of-view. The compressed output from each optics is directed through a polarizer and filter to a phase shifter. The phase shifter, a pair of birefringent crystals, encodes the angle of incidence of the laser beam as a phase shift between the two components of the polarized input beam. These components, the e-ray and the o-ray travel different paths through the phase shifter. Subsequently, an analyzer such as a Wollaston prism decomposes the beam into two linear components. These components are condensed through a reimager lens and coupled to a pair of intensity detectors.

Abstract: A solid brush current collecting system for dynamo-electric machines which selectively uses compatible materials in different applications for the moving and stationary contact members. Brushes of different compositions are disclosed and the current transfer and collecting members are operated in an inert gas atmosphere, such as carbon dioxide, having either water or organic additives, such as alcohols, hydrocarbons, ketones, and the like, to achieve operation of the current collector system at higher temperatures, higher velocities and higher current densities than is possible with conventional systems. Low friction and low wear rates are in part achieved by operating the contact members in a low temperature environment.

Abstract: A method and apparatus is shown and described for remotely closing a well(s) without the possibility of accidental closure. The method and apparatus will have a significant application to underwater wells. A point of activation of a gas generator is remotely located away from the well to avoid debris that may fall at or near the well. A diver or technician brings the means for activating the gas generator to the activation point of the gas generator. Upon activation, pressure generated by the gas generator is transferred by appropriate conduit means to well closure equipment which may include a crimping device, a "U" type blowout preventer, blind rams or any combination thereof. The faces of rams used to pinch concentrical strings of pipe may be shaped to seal the outer strings of pipe as well as inner strings.
