Abstract: Correction of eye refractive errors like presbyopia, hyperopia, myopia, and astigmatism using either pre-tensioned or transcutaneously energized artificial muscle implants to change the axial length and anterior curvatures of the eye globe by bringing the retina/macula region to coincide with the focal point. The implants are scleral constrictor bands, segments or ribs for inducing accommodation of a few diopters, to correct refractive errors on demand or automatically. The implant comprises an active sphinctering band encircling the sclera, implanted under the conjunctiva and under the extraocular muscles to uniformly constrict the eye globe, to induce active temporary myopia (hyperopia) by increasing(decreasing) the length and curvature of the globe. Multiple and specially designed constrictor bands enable surgeons to correct astigmatism.

Abstract: A system for precisely measuring muzzle exit velocity of a “muzzle loaded” mortar projectile fired from a mortar tube using two back-biased Hall effect sensors for projectile gas ring channel detection. The system includes a back-biased Hall effect sensor block, a digital resolver electronic circuit and a computer software interface. The back-biased Hall effect sensors are located in a calibrated sensor block attached to a mortar tube. As the projectile metal casing passes a face of the sensors, the sensors trigger and release, providing two electronic pulses. The pulse edges are captured in the resolver electronics, containing a discriminator circuit for filtering all input pulses to distinguish between a projectile loading event and a projectile firing event. Once a valid firing event is detected, an output of precision timers is presented serially to a computer where it is processed and displayed by a computer software interface.

Abstract: Surgical correction of presbyopia and hyperopia by a circularly distributed assembly of mini-bridges implanted between the interior surfaces of the ciliary muscle and the exterior surface of the lens capsule, for augmenting the transmission of the contraction force of the ciliary muscle/zonule assembly to the lens capsule. The lens is symmetrically squeezed by mini-bridges acting in concert with the ciliary muscle thus changing the curvature of the lens. The mini-bridges are composite synthetic muscles comprising either passive biocompatible mini-bridges made with polymeric gels, silicone polymers or a composite, electromagnetically or mechanically deployable mini-bridges, inflatable balloons or synthetic muscles. The surgical procedure comprises using a ciliary muscle relaxant to stretch the lens/zonules/ciliary muscle assembly.

Abstract: A automated AC line filter and surge suppression apparatus 100 having an inductive current sense loop (ICSL) circuit 10 for sensing inductive current at a load and controlling the application of AC line filter 112 to an AC power line to the load. Current sensor 12 in series with the input line senses inductive load current. A first bridge rectifier 14 rectifies the sensed load current to a proportionate DC voltage, which triggers a switch 24. The output of switch 24 is fed into an opto-isolator 26, which in turn controls second switch 28. Switch 28 connects or disconnects AC line filter 112 from the system according to a predetermined sensed inductive current at the load. MOVs 102 and capacitive elements 104 provide continuous surge suppression protection to the load.

Abstract: A new power supply topology is described consisting of an input h-bridge or half-h-bridge, a low coupling coefficient transformer such as an air core transformer, a secondary resonant circuit, and a voltage multiplier which includes a series output capacitance. The topology is advantageous for high voltages since the reduced coupling leads to large spacings reduced insulation requirements.

Abstract: A personnel x-ray inspection system includes an electron source that provides a pencil beam of electrons. An electromagnet assembly receives the pencil beam of electrons and directs the beam of electrons along a line to form a scanning redirected beam under the control of a scan command signal. The scanning redirected beam strikes a target and generates a cone of x-rays that moves along a target line as a result of the scanning redirected beam. A collimator receives the scanning cone of x-rays and generates a collimated traveling pencil beam, which is directed to a person under inspection. A moving platform translates the person under inspection through the collimated traveling pencil beam. A backscatter detector detects backscattered x-rays, and provides a backscattered detected signal indicative thereof. A system controller provides the scan command signal, and also receives and processes the backscattered detected signal.

Abstract: The invention provides a technique for pattern recognition that employs a state machine that incorporates a sequence of table-look-up operations. A sequence of input parameters, derived according to an application-specific algorithm, generates a corresponding sequence of memory addresses for these operations. The memory tables are organized in a hierarchical structure that corresponds to the input sequence. Table data is designed to recognize a specific library of input patterns. An input sequence traces an input-specific path through the memory tables until one of the patterns in the library is recognized or until it is determined that the input sequence is inconsistent with any of the library patterns. For each library pattern, the table data is designed to accommodate the variations in the input values that are specific to the application (e.g., variations due to noise and/or tolerances). Table data can be derived by analysis, simulation, learning or a combination of these methods.

Abstract: A method for protecting the video memory on a computer system from being illicitly copied. The invention decrypts a previously encrypted image and displays it on the video screen. During the time the image is displayed, the invention protects it from being copied by other running applications. This is accomplished in multithreaded operating systems by first issuing a multithreaded locking primitive to the video memory resource, and then inserting a pending video hardware request that will take precedence over any subsequent video memory access requests. The pending request serves the purpose of destroying the contents of video memory. The pending request is passive in that it does not execute unless a malicious program has removed the video memory lock.

The modules are quickly stacked together and snapped in place in a manner supporting severe environmental conditions.

Abstract: A navigation and guidance computer system using navigation sensors to determine aircraft position, and automatically control the aircraft to fly from an initial position to intercept and follow a crew-selected rendezvous orbit in accordance with Air Traffic Control and military specified rules. It creates maneuvers that result in smooth, efficient motion of the aircraft from an initial position to the execution of a rendezvous orbit. It controls the aircraft by applying commands to the aircraft's autopilot. The system creates the smooth and coordinated maneuvers by considering and anticipating all constraints on the aircraft flight path by creating a single maneuver that is a re-entry maneuver, an over fly maneuver, and a turning maneuver all as a single turn that is contained entirely within the allowable airspace. All maneuvers are created and executed recognizing the turning capability of the aircraft considering allowable bank angles, current wind conditions and true airspeed.

Abstract: A remotely controlled rescue craft for use in fast moving water to rescue victims. A line is strung and secured across the moving water and the craft is tethered to the line. The craft has a water passage port that runs through the length of the craft. Within the passage port are a remotely controlled rudder for steering the craft, and at least one remotely controlled stabilization plate for controlling the pitch of the craft. Pressure relief channels run from the passage port to each side of the craft to keep the craft from rocking from side to side. A sealing ball is in each pressure relief channel and is pressed against a seal in an opening in the channel when the channel fills with water. A remotely deployed life preserver can also be onboard the craft. A control box controls all the onboard systems.

Abstract: A padding is placed around an underground irrigation pipe which allows the irrigation pipe to flex and bend when the irrigation pipe is struck or compressed. The padding is preferably a synthetic polymer that substantially reverts back to its original size after the compressing force is removed and is not affected by the elements. The padding is used over the irrigation pipe in areas of heavy traffic over the pipe or areas where the pipe may be struck. The pipe can be inserted into apertures in the padding or slits can be made in the padding to allow insertion of the pipe into the apertures. These channels can be prefabricated or cut into the padding as needed.
