Granted: 1994-09-27
Abstract: Abstract A process for colorizing a high information density black and white image comprises generating color inform-ation for the image at an information density lower in some aspect than the information density of the original black and white image.  This color information is then computer processed at the lower information density to produce processed color information.  The processed low information density color information is then combined with the high information density black and white information to produce a high information density full color image.

Abstract: INVENTION:  AIR FILTRATION UNIT               INVENTOR: ARTHUR TIBBITS              ABSTRACT OF THE DISCLOSURE   A portable top-loading air filtration unit adapted to receive sheet-like filter material comprises a housing having a compartment-defining housing portion and a cap. The compartment-defining housing portion has an open top but otherwise defines a compartment closed against passage of air. The cap is extensively apertured to define an air inlet permitting intake of large volumes of air and is releasably secured to the compartment-defining housing portion. An grate below the cap receives andsupports sheet-like filter materials which present a large effective cross-sectional flow area. These may include chemically-interactive filter materials such as activated charcoal and potassium permanganate oxidizing materials and also a HEPA filter for filtering minute particulates. An air outlet is formed in the compartment-defining housing portion below the filter support structure and an electrically-powered air flow producer is located within the compartment proximate to the air outlet. The producer has an inlet port receiving air from the compartment and a tubular exhaust port which is sealed to the air outlet. The effective cross-sectional flow areas of the air inlet, air outlet and producer exhaust port are selected to permit high volumetric flow rates while permitting more effective use of chemically-interactive filtering materials.

Granted: 1991-11-19
Abstract: ABSTRACT       A polyurethane dispersion contains (A) an organic solvent, (B) a polyurethane resin having a molecular weight of 20,000 - 500,000, and (C) fine particles obtained from an active-hydrogen containing polyfunctional compound, which contains functional groups having a molecular weight of 50 or smaller per functional group, and an organic polyisocyanate.  The dispersion can be converted into an emulsion by emulsifying water therein.  A sheet-like porous material is also obtained by impregnating and/or coating a base material with the emulsion, causing the thus-coated emulsion to gel and then drying the resultant base material.  The dispersion has excellent stability.  The emulsion can be gelatinized at a relatively high temperature in a rather short period time, thereby permitting efficient production of the sheet-like porous material. The sheet-like material has a very fine porous structure, is excellent in various properties and has superb water vapor transmission characteristics.  It is useful as a raw material for various synthetic hides, namely, for clothing, shoes, waterproof cloths, tents, wall paper, flooring, filter media, filters for air conditioners, etc.

Granted: 1991-08-13
Abstract: ABSTRACT      A sterilizable catheter of small diameter has a central coherent fiber bundle for carrying an image to a viewing means, and the fiber bundle is surrounded by light fibers.  The proximate end of the catheter is provided with a coupling means for aligning the coherent optical bundle with the optical system of the viewing means and for providing an interface with light transmitting means to transmit light from a light source along the light fibers to the body cavity.  The coupling means may have a diameter no bigger than the diameter of the covering of the catheter.  When the catheter is used inside a larger endoscope or a trochar, the endoscope or trochar can be removed while the catheter remains in place.  This is accomplished by removing the viewing means and sliding the endoscope or trochar over the catheter and then replacing the viewing means for further viewing within the body cavity. This device can be used for detection for cancer cells and treatment thereof by phototherapy.  A fluorescent dye is attached to the cancer cells and subsequently exposed to an exciting laser light frequency. The fluorescent light is transmitted and displayed on the video monitor and the same light frequency is then transmitted through the light fibers to the cell for phototherapy treatment.

Abstract: PROTOCOLS FOR VERY HIGH-SPEED OPTICAL LANs Abstract The present invention relates to packet switched interconnection protocols for -use in high-speed optical Star-configured Local Area Networks (LANs). In the present Star LAN, a plurality of N+1 wavelength division multiplexed (WDM) channels are provided for use by M transceivers connected to the Star coupler, where preferably M>N. N of the N+1 WDM channels are used for transmission of data packets, and the remaining WDM channel is used by all transceivers for transmitting control packets only. In the present protocols, a transmitter in an active transceiver first send a control packet over the control channel using a first protocol such as, for example, ALOHA or CSMA. The control packet includes (1) the transmitter's unique address, (2) the destined receiver's address, and (3) the address of the data channel to be used in transmitting the associated data packet. Immediately after the control packet is sent, the associated data packet is transmitted over the chosen one ofthe N data channels using a second protocol such as, for example, ALOHA, CSMA or N-Server Switch. In the Star network, the transceivers receive their own transmissions and detect if a collision or not has occurred, and if a collision is detected the transmission procedure is repeated until successful.

Abstract: Abstract of the Disclosure LASER BALLOON CATHETER     A laser balloon catheter intended primarily for coronary angioplasty includes a flexible tube having an inflatable balloon secured to its distal end, a central shaft within the balloon for carrying a guide wire, an optical fiber for carrying laser radiation through the flexible tube into the balloon, and a tip assembly in the balloon for directing laser radiation outwardly through a major portion of the balloon surface while limiting shadowing by the central shaft.  The tip assembly preferably includes a tip portion of the optical fiber contained within a transparent, heat-formable tube and formed into a spiral shape around the central shaft by the heat-formable tube.  The optical fiber tip portion is tapered so that it directs laser radiation outwardly over its length. Deuterium oxide is preferably used for inflation of the balloon because of its very low attenuation of laser radiation in the wavelength range of interest.  The disclosed laser balloon catheter is capable of delivering 30-40 watts of laser radiation to a surrounding artery for times on the order of 30 seconds without excessive heating of the balloon assembly.
