Abstract: A linear motion electric power generator for generating electric current from work done by an intermittent force. A moving magnet is confined so that it can move with bi-directional linear, or approximately linear, motion through each of at least two coils. The coils are spaced apart from each other and connected electrically so that current produced in a first coil as a result of movement of the moving magnet is substantially in phase with current produced in said second coil. Preferred embodiments are described for providing electric power generation from extremely lower power mechanical forces. Embodiments of the invention are useful for providing power for long life flashlights, for alarm systems and for communication devices located at places where conventional electric power sources are unavailable. Another preferred embodiment is a low profile unit which derives its mechanical from repetitive forces such as the forces on the heel of a shoe during walking or running.

Abstract: A mechanical to electrical pulse power generator. Powerful rare-earth magnets (e.g., Neodymium-Iron-Boron, or Samarium-Cobalt) create strong flux fields. These flux fields are used to produce large percent change in flux through a coil of wire upon the triggering of triggering mechanisms which causes a snap action to assure creation of an electrical pulse sufficient to activate an alarm. A mechanical force in a first direction will cause a jerk action which will produce a pulse shape identifiable to the first direction force and a mechanical force in a second direction will produce a different jerk action which will produce a pulse shape identifiable to the second direction force. Low power electronics use the energy in these pulses to activate a radio frequency transmitter to transmit a signal revealing the direction of the mechanical force. A preferred embodiment codes the transmitter signal to indicate the source of the signal.

Abstract: A linear motion electric power generator. A rare earth magnet and a coil are positioned to move linearly back and forth relative to each other. The movement of the coil in the field of the magnet generates a current in the coil. Springless orientation means are provided to maintain a neutral position about which the relative motion occurs.

Abstract: A magnetic stimulator device for inducing electrical pulses in human or animal nerve tissue. A high power electrical current source provides specially defined current pulses to a magnetic coil which produces non-uniform magnetic fields which are concentrated at a location near one position on the coil and reduced at locations near other positions on the coil. In a preferred embodiment of the present invention a variable resistance switch is used to control the shape of the induced pulses.

Abstract: The present invention provides reflecting chaff microellipsoids having a surface of electrically conducting material. A preferred embodiment consists of S.sub.i O.sub.2 (95%), Na.sub.2 O (1%), B.sub.2 O.sub.3 (4%) microspheres coated with silver. The present invention is best suited for reflecting electromagnetic radiation within the range of about 100 GHz to 100,000 GHz.
