Abstract: Presented are electronically controlled optical shutter spectacles for achieving biofeedback between the operation of the optical shutter spectacles when worn and the physiological rate and timing of human visual processing of the wearer of the spectacles to provide further enhanced perception of fast-moving objects or surroundings and to train and condition the human physiology to retain enhanced motion perception capability for an indeterminate time following removal of the spectacles.

Abstract: Presented is a method and apparatus for providing human visual physiology with a perceived continuous image of a fast-moving object formed by a series of visual pulses each followed by a period of visual blockage where the frequency of these repetitive pulses/blockages is selectively adjusted to be close to the actual flicker fusion frequency of the observer at the perceived brightness of the visual pulses. The objective of this method is to provide the observer with enhanced visual. perception of fast-moving objects. The method and apparatus presented is intended for use under natural lighting conditions and continuous artificial lighting conditions and is accomplished by spectacles with optical shutter lenses. The lenses are alternately opened to provide the wearer with an unhampered view of the surroundings and then closed to block out the view and as much light transmissibility as possible.

Abstract: A ski control system incorporating carve control amplification to activate by deployment of auxiliary ski control surfaces, such as a probe assembly resiliently mounted on the ski at or near the center of pressure of the ski, and which functions when deployed to impose control forces on the ski in proportion to the degree of carve of the ski.

Abstract: A method and apparatus is presented for successively interrupting the transmission of light through a transparent body at a frequency such that a scene viewed through the transparent body by a human eye is perceived as a continuous image that is less bright than actually, and is viewed with minimal color distortion. In one aspect of the invention, the lenses of spectacles are provided with a layer of liquid crystal material that is normally transparent, but which responds to the application of an electrical charge to render the liquid crystal layer non-transparent. By adjusting the frequency of application of successive electrical charges, the lenses admit light at full brightness for small increments of time, with minimal color distortion, and interrupt the transmission of light for small increments of time, so that the light admitted at full brightness is perceived as being less bright or dimmed.

Abstract: Presented is a universal integral ski control system including a base member on which is mounted a drag control probe assembly including probes that are selectively displaceable between a retracted position and an extended position in which the control probes extend past the running surface of the ski so as to project into the snow on opposite sides of the ski when the skis are in use. The probe assembly is manipulable by the skier for selectively effecting displacement of the drag control probes into either a retracted position or extended position. The base is universally applicable in that it may be integrally incorporated into a ski boot and thus be available for use when the ski boots are donned and the skier steps into the ski bindings, or it may be incorporated integrally into the toe piece assembly of the bindings, or under the toe piece, or incorporated integrally into the ski itself.

Abstract: Presented is a method and apparatus that permits a skier to control the speed at which he descends a ski slope. In terms of structure, the invention includes a pair of probes mounted on each ski that protrude below the running surface of the ski and thereby drag in the snow. The probes may be controlled as to the depth of penetration of the snow either before the skier starts his run, or during his descent. Having deployed the probes, added manueverability control is achieved merely by conventional body movements which affect the depth to which the probes penetrate the snow.

Abstract: A rocket system wherein a frustoconical or cylindrical casing contains fi and second rocket stages in series, with each stage having a nozzle extending in an aft direction. Each stage contains a solid rocket fuel, with the forward end of the fuel in the first stage filling and surrounding the nozzle of the second stage so that when the casing is severed along a plane aft of the second stage portion of the case the pressurized combustion products in the first stage forces the stages to separate.

Abstract: Presented is a method and apparatus that permits a skier to control the speed at which he descends a ski slope. In terms of structure, the invention includes an integral probe assembly including a pair of probes mounted on each ski at about the center of gravity that protrude below the running surface of the ski when deployed and thereby drag in the snow. The probes may be controlled as to the depth of penetration of the snow either before the skier starts the downhill run, or during descent. The skier may also retract the probes so as eliminate the control and maneuverability that they provide. Having deployed the probes, added maneuverability control is achieved merely by conventional body movements which affect the depth to which the probes penetrate the snow. The probe assembly may be incorporated in the skis during manufacture of the skis, or may be added to the skis subsequent to manufacture.

Abstract: A split flow injector for solid fuel ramjets (SFRJ) having a tube injected nto the injector port of a SFRJ to split the air into two streams wherein the primary airflow through the annular area around the tube is injected into the recirculation region just inside the injector port to stabilize combustion.
