Abstract: An apparatus for stimulating regeneration and repair of damaged spinal nerves, comprising at least two electrodes placed intravertebrally near the site of spinal neurite injury and delivering direct current thereto. A method for stimulating regeneration and repair of damaged spinal nervous tissue, comprising placing electrodes intravertebrally near the site of spinal cord injury and applying direct current at a level sufficient to induce regeneration and repair of damaged spinal neurites but less than the current level at which tissue toxicity occurs.

Abstract: A toy gas-fired missile and launcher assembly whose missile is composed of a soft head and a tail extending therefrom formed by a piston. The piston is telescoped into the barrel of a launcher having a closed end on which is mounted an electrically-activated ignitor, the air space between the end of the piston and the closed end of the barrel defining a combustion chamber. Joined to the barrel and communicating with the chamber therein is a gas intake tube having a normally-closed inlet valve. To operate the assembly, the operator places the inlet tube with its valve open adjacent his anal region from which a colonic gas is discharged. The piston is then withdrawn to a degree producing a negative pressure to inhale the gas into the combustion chamber to intermix with the air therein to create a combustible mixture. The ignitor is then activated to explode the mixture in the chamber and fire the missile into space.

Abstract: Regeneration of damaged tissue, whether in the skin, tendons or elsewhere in the body begins with the growth and proliferation of cells which take place along a migratory path and in a polar direction that depends on the nature of the injury. Thus in some situations, regenerative cells and non-cellular healing components migrate radially from the outskirts of the damaged tissue region toward the center thereof, while in others migration is along a longitudinal or transverse path. To stimulate and enhance this regenerative process and thereby promote rapid healing of the damaged tissue, use is made of an exogenous electrical stimulation technique in which cathode and anode electrodes are placed in or near the region. Impressed across the electrodes is a DC potential whose magnitude is sufficient to cause a minute ionic and electronic current to flow between the electrodes through the region.

Abstract: A biomagnetic analytical system for sensing and indicating minute magnetic fields emanating from the brain or from any other tissue region of interest in a subject under study. The system includes a magnetic pick-up device constituted by an array of fiber-optic magnetic sensors mounted at positions distributed throughout the inner confines of a magnetic shield configured to conform generally to the head of the subject or whatever other body region is of interest. Each sensor yields a light beam whose phase or other parameter is modulated in accordance with the magnetic field emanating from the related site in the region. The modulated beam from each sensor is compared in an interferometer with a reference light beam to yield an output signal that is a function of the magnetic field being emitted at the related site.

Abstract: A stereosopic (3-D) converter assembly usable in conjunction with a standard 2-D closed circuit TV system in which a video camcorder (video camera+VCR) functions to record moving images of a scene seen through the monocular lens of the video camera and to play back the recording to yield a composite video signal that is fed to a TV monitor on whose screen the images are exhibited. The assembly is constituted by a shuttered binocular optical attachment placed in front of the camera lens, a binocular electro-optical viewer through which the screen of the monitor is seen by an observer, and a controller unit for activating either the attachment or the viewer. In the recording mode of the assembly, the controller unit in response to vertical sync pulses derived from the composite video signal yielded by the camera activates the optical attachment alternately to present to the camera lens left and right eye images of the scene, this action resulting in a 3-D recording.

Abstract: The invention relates to method and apparatus for in vivo mammalian nerve regeneration of a damaged nerve using an electric current through the damaged nerve while the nerve ends are abutted against one another, sutured together or spaced apart from each other. The apparatus is implantable in a human body so that the electric current can be maintained for an extended period of time to produce regeneration of the damaged nerve.
