Abstract: A distributed strip-type radiating cable comprised of a plurality of generally flat conductive strips disposed in substantially parallel relationship to one or more generally flat dielectric materials, adapted to radiate RF energy for communications applications. The radiating cable is designed to be efficiently and inexpensively manufactured and installed from lightweight, small size materials, and is designed to be easily attached and secured to a variety of surfaces.

Abstract: The assembly comprises a band, mountable on the leg, carrying all of the components of the assembly to provide a self-contained unit. The components comprise: electrodes for stimulating a leg nerve; a V-shaped plate for conforming with the leg's tibia to reproducibly position the band so that the electrodes are located over the nerve; a tilt sensor for measuring the angular position of the lower leg; a control circuit for processing the sensor signal information and emitting pulses through the electrodes to stimulate the leg in response to phases of body movement; and a battery for supplying power to the tilt sensor, control circuit and stimulator. By comparing the assembly's stimulation states against a known template defining optimal stimulation states, stimulation threshold parameters can be fine tuned without the need for repeated trial and error testing by the user.

Abstract: Substantially anhydrous magnesium chloride is prepared through the chlorination of a hydrated magnesium chloride by melting the hydrated chloride, feeding that molten material to a bed of carbonaceous material so that it flows downwardly therethrough and simultaneously feeding a mixture of chlorine and air to the bed of carbonaceous material so that it flows upwardly therethrough countercurrent to the molten material, until magnesium chloride of the desired state of purity is obtained, and the purified magnesium chloride is then recovered.

Abstract: A method and an implantable electrical unit are for use in effecting a direct connection between external apparatus and the nervous systems either to receive information contained in the electrical activity of selected nerve fibers or to transmit thereto information in the form of a stimulating electrical input closely approximating the natural form in order to attain appropriate neural response, in either case with a high degree of discreteness. The method and the unit provide for the regeneration of severed nerve fibers in passageways. The unit includes a member in which the passageways are formed and which is of a material that is electrically non-conductive, and biologically inert and which has electrodes incorporated in the member, each electrode exposed in an appropriate one of the passageways.
