Abstract: A method and apparatus are disclosed for improving bodily safety during exposure to an eye hazardous monochromatic treatment light source by diverging the light, such as with a diffusing unit attached to the light source distal end so that the radiance of the light exiting the distal end is an eye safe level. At a first position of the light source distal end substantially in contact with an outer surface of a target, the energy density of an exit beam from the distal end is suitable for effecting a desired treatment, and at a second non-contact position of the distal end the exit beam energy density is significantly less than a value suitable for effecting the treatment. In an additional embodiment, the diverging or diffusing unit has a device for evacuating vapors or particles from the target.

Abstract: Apparatus driven by high-frequency AC current source, for driving an electric load with low-frequency AC current, that comprises a current splitting inductor, for generating, from the high-frequency current source, a first and a second high-frequency AC current sources; a rectifier, coupled to the splitting inductor, consisting of rectifying diodes for rectifying the first and second high-frequency current sources, and capacitors, charged by the diodes, the capacitors being corresponding to the first and second DC current sources; a controllable half-bridge commutator having a first and a second control inputs, the commutator being coupled to the DC current sources, for commutating the DC current sources, for allowing to generate, from the DC current sources, the low-frequency AC current required for driving the electric load; and a control circuitry, having a first and a second outputs, the outputs being coupled to the first and second control inputs, respectively, and outputting two complimentary pulse trai

Abstract: The present invention is directed to at least one tie strap positioned on an inflatable blanket. These tie straps, when being used with the blanket, are positioned not on the non-inflatable periphery sections of the inflatable blanket, but on non-periphery sections, like an inflatable section, of the inflatable blanket. This is being done to provide the desired control of the blanket's movement and, if desired, the inflation of the blanket in certain areas of the inflatable blanket. Controlling the inflation of the blanket is obtained by the present straps ability to alter the size of at least a portion of an inflatable chamber within the inflatable blanket. The present ties also provide greater movement control because the tie straps provide desired pressure to at least one section of the inflatable blanket. The tie straps of the present invention are also an integral part of the blanket which means supplemental materials, like tape or ropes, are not needed to control the blanket with the present invention.

Abstract: A method and apparatus for suppressing a fire utilizing non-azide solid gas propellant generation to produce and transport a suitable gas for suppressing a fire in a normally occupied area. The nitrogen gas produced by the solid propellant gas generation is optionally treated to remove undesirable elements such as water and/or carbon dioxide from the product gas prior to the delivery of the product gas to the protected hazard area.
