Abstract: An apparatus and method for selecting a storage location in a memory device including receiving at least one of a pre-decoded location address signal, a match signal, and a redundant location address enable signal, enabling one of a decoder and a redundant decoder in response to the match signal, wherein the decoder is operable to generate a location select signal for selecting a first location, the decoder being responsive to the pre-decoded location address signal, and wherein the redundant decoder is operable to generate a redundant location select signal for selecting a second location, the redundant decoder being responsive to the redundant location address enable signal, and terminating one of the generation of a location select signal and the generation of a redundant location select signal in response to a precharge signal.

Abstract: The present invention is directed to a see-through bookbag and, according to one embodiment, a see-through book bag containing an envelop for carrying artwork or advertising material.

Abstract: A phase controlled regulator for selectively connecting a load to an AC source voltage such that substantially constant power is delivered to the load despite fluctuations in the magnitude of the source voltage is comprised of a circuit for detecting the zero crossings of the AC source voltage. A circuit produces a reference signal representative of a periodically increasing value in response to the zero crossings of the AC source voltage. A sensor produces a first signal representative of the instantaneous value of the AC source voltage. A comparator compares the reference signal with the first signal and produces an output signal when a predetermined relationship exists therebetween. A switch is responsive to the output signal for selectively connecting the load to the AC source voltage.

Abstract: A steam sterilization cycle having a conditioning stage, a sterilizing stage, a drying stage and an air admission stage which provides maximum removal of entrapped air from full or partial porous loads. The conditioning stage includes a plurality of pressure/vacuum pulses. The final vacuum pulses are deeper than the initial pulses. The sterilizing stage includes a diffusion dwell come-up which gradually increases the temperature and pressure of the chamber to the predetermined sterilization temperature by a sequence of pressure rises followed by pressure plateaus which permit substantially complete steam penetration of the load and substantial equalization of the actual load temperature and the temperature sensed by the sterilizer controls and substantially eliminates superheating the chamber. The cycle may also include a step for detecting and reacting to unacceptable levels of noncondensable gas present in the chamber during the sterilization stage.

Abstract: Imaging apparatus including an image intensifier and first and second assemblies for filtering or color encoding incident light before it is received by the image intensifier, and produced light emitted from the image intensifier, respectively. An objective lens and an eyepiece are provided for passing the incident light to the first filtering assembly and for passing the produced light to a predetermined location, preferably to an observer. The first and second filtering or encoding assemblies remove from the light, components falling within at least one predetermined range of frequencies. The filtering assemblies may be two disks, an input disk and an output disk, positioned on opposing sides of the image intensifier. Each disk may have one or more filters. Each filter is adapted for removing from the light all components except those having a wavelength falling within a predetermined range of wavelengths.

Abstract: A lighting fixture having a plurality of light source means arranged circumferentially around the axis of symmetry of the lighting fixture and a reflector system for folding and mixing the light emitted from the light source means to provide a single beam to simulate the light emitted from a single light source means. The light rays converge at an acute angle relative to the axis of symmetry to provide the single beam. The reflector system includes a plurality of source reflectors, each being operatively associated with one light source means, a second reflector positioned beneath the plurality of source reflectors to receive light therefrom in an overlapping fashion, and a third reflector radially spaced and partially circumscribing the source reflectors and the second reflector to receive light from the second reflector and to project that light to form the single beam.

Abstract: An assembly for permitting a sterile person to control adjustable equipment in a sterile field without contamination to the person or the field. The assembly includes a cover having two halves which can be folded together over the handle of the equipment in a closed position to isolate the handle from the sterile field. A flap on the cover isolates a control panel on the equipment from the sterile field. The assembly also includes a container in which the cover is sterilized and with which the cover is so applied to the handle following sterilization that the container provides a barrier against contamination of the exterior of the cover during such application. The container is structured to maintain the cover in a partially closed position and is adapted to be so deformed that the container can move the cover from the partially closed position to a closed position around the handle.
