Abstract: In the present invention, personal air filtration unit sold as SMARTMOUTH™, a trademark for a personal air filtration unit comprised of an outer activated carbon pre-filter and an inner filter for particulate matter available through Tri-Pact Enterprises has been attached to a column of valve connectors which are connected to a tracheostomy tube. The filter has a downwardly dependent exhaust port which allows expired air to flow out of the filtration unit without passing through the filters, thereby helping to prevent mixing of inhaled and exhaled air, and decreasing resistance to exhalation, as well as one-way valves in the form of a flap, on the one hand to prevent exhaled air from entering a dead space between filters, and on the other hand to prevent entering of inhaled air through the exhaust port.

Abstract: A fiber optic display apparatus consists of a plurality of optical fibers which convey a projected image from an input, or first surface, to a display, or second surface, whose area is greater than or equal to that of the first surface, such that any image projected on to the first surface appears enlarged on the second surface. The second surface is comprised of tiles which attach to adjoining tiles by means of flexible tabs and pliable locator rods in such a fashion as to allow the second surface to follow general contours (e.g. concave or convex), while the optical fiber bundles from each tile are collected into a fixture to form the first planar surface. Because of the modular design of the display it can be assembled or disassembled rapidly.

Abstract: The present invention is a fan motor for use in various types of electronic equipment, more particularly fan motors which may cool heat radiating electronic parts, in which the object is (a) to prevent noise caused by the air-cutting sound of the fan motor, (b) to allow easy alteration of the blowing direction, and (c) to eliminate damage caused by the counter electromotive force of the field magnetic coil.The fan motor of the present invention consists of (a) a rotor formed by installing permanent magnets on a vane wheel, and (b) a stator formed by installing an electromagnet and a magnetic body on the inside circumferential surface of a casing. A circumferential-edge ring is installed on the vane wheel, so that noise caused by the air-cutting sound of the fan motor is prevented. A conductive circuit is connected to the field magnetic coil of the electromagnet, and the aforementioned magnetic body can be selectively positioned in a relatively advanced angular position (P.sub.

Abstract: The invention involves a portable and mobile power distribution device which can provide 12,000 watts of power and needs only a 220 volt source. The invention specifically involves a two wheel support stand comprising a 12,000 watt distribution panel situated atop an outlet box containing 110 volt AC 3-prong grounded duplex outlets, with a male turnlok connector socket for a 220 volt, 100 amp power cable with a female plug mounted in the center of the distribution panel.
