Abstract: An apparatus and method for training a search engine generates synthetic search arguments and target information that are provided to the search engine as training. A search argument simulator ingests product information and historical interaction data, determines relevant descriptors, creates compound descriptors, and creates candidate search arguments. A trainer checks the candidates against historical search arguments, identifies similar search arguments and determines likely search arguments that are used for training. An evaluator monitors search engine responses and triggers retraining of the search engine.

Abstract: An apparatus for shaping an edge of an aerofoil, the apparatus having first and second brushes and each brush having a plurality of bristles. A first motor rotates the first brush about a first axis and a second motor rotates the second brush about a second axis. The axes are arranged substantially parallel to the bristles of the respective brush. A support structure holds the first brush such that the first axis intersects a first surface of the edge of the aerofoil and holds the second brush such that the second axis intersects a second surface of the edge of the aerofoil. There are means to produce relative movement the first and second brushes and the aerofoil such that the first and second brushes move longitudinally along the edge of the aerofoil to shape the edge of the aerofoil.

Abstract: An assay method and kit for detecting the presence of a predesignated, target IgG antibody in a sample selected from one or more patient bodily fluids. The method comprises the following steps: (a) contacting the sample of one or more patient bodily fluids with a membrane-bound recombinant protective antigen to bind to the target IgG antibody in the sample; (b) previously, simultaneously or subsequently to step (a), binding the protective antigen (PA) with a conjugated label producing a detectable signal; and (c) detecting the signal whereby the presence of the target IgG antibody is determined in the sample by the intensity of the signal. The method can further comprise the step of evaluating immunization status of the patient from whom the sample came by comparing the signal or lack thereof with immunizations previously received by the patient. In a preferred embodiment, the recombinant protective antigen (PA) specifically binds to anthrax protective antigen-specific IgG antibodies.

Abstract: A random number generator seeding method and apparatus which includes the provision of an RNG seed register and means for capturing a current count number from one or more fast running counters contained within the apparatus upon the occurrence of an act or acts by an apparatus operator as he performs the normal set-up and initialization function. In the preferred embodiment means are provided for sensing particular acts of the operator, and upon detection of each such “event”, one or more of the counters within the system are read and the count value is appended to previously captured counter values until the desired seed length is obtained. At this time, the RNG is said to be seeded, the initialization phase is completed and the apparatus may be made available to players to commence game play or other use of the apparatus.

Abstract: A cryptographically secure random number generating system includes a random number generator for generating random numbers, an encryption engine, and a modulus offset unit. The random number generator has a valid output set consisting of M−1 random numbers, and an invalid output set including one invalid output value. The encryption engine is responsive to the random number and to the invalid output value, and operative to encrypt the random number to provide an encrypted random number, and further operative to encrypt the invalid output value to provide an encrypted invalid output value. The modulus offset unit includes: a sub-modulo for adding, in modulo M, the invalid output value to the encrypted random number to determine a sum; and a sub-modulo for subtracting, in modulo M, the encrypted invalid output value from the sum to determine a cryptographically secure random number.

Abstract: A gas fireplace is provided having a plenum formed around at least a portion of the fireplace firebox. Room air enters the plenum and is heated by the firebox prior to venting back into the room. Two openings are provided from the outside of the fireplace housing to the plenum. The first opening allows heated air to exit the plenum, while the second opening allows cool outside air to enter the plenum. a mechanism is provided to control the amount of heated air exiting the first opening and the amount of cool air entering the second opening. By controlling the inflow and outflow through the first and second openings, respectively, the amount of the fireplace by-products generated into the room where the fireplace is located such as carbon-monoxide, nitrogen dioxide, heat and moisture are reduced.

Abstract: A vent free gas fireplace comprises a housing and a firebox within the housing spaced-apart from the housing walls to provide top, bottom, rear and side plenums. The side plenums are divided into upper and lower side plenums. Room air enters the lower side plenum and passes into the rear plenum, the combustion chamber and the upper side plenum. Exhaust gases pass from the combustion chamber through a catalytic converter and into the top plenum. The hot exhaust gases are combined with room air from the rear plenum and pass into the upper side plenums, combining with additional room air, and then out into the room.

Abstract: A dispersion-strengthened composite that includes a glass matrix reinforced with submicron-sized filler particles not crystallized from the matrix and the use of colloidal processing techniques to prepare such composites and unfilled glass materials as well.

Abstract: An extracting tool for removing an electronic plug-in module from a chassis ssembly applies, by mechanical advantage, a large extracting force to a module. An extractor plate engageable with a plug-in module is slidably connected to a frame and a rotatable cam is provided for linearly moving the extractor plate. A handle integral with the cam is used for rotating the cam, and a cam surface on the handle is used to return the extractor plate to a starting position when the handle is moved in a reverse direction.

Abstract: Acid and base catalyst substances are employed in the photochemical process for collection and retrieval of solar energy wherein a lower energy level isomer (e.g. trans-isomer) of a photochemical isomerizable compound is exposed to solar energy of a wavelength providing a higher energy level isomer (e.g. cis-isomer) of this isomerizable compound and this higher energy level isomer subsequently is transformed to its lower energy level isomer with exothermic release of thermal energy for useful purposes. In this process the transforming or conversion of the higher energy level isomer to its lower energy level isomer is facilitated by the presence of and/or contacting with the acid or base catalyst substance.

Abstract: The carnivore food is composed essentially of ground raw meat and dried cooked cereal, optionally supplemented with other protein, and extruded as continuous extrusions each composed of successive slugs adhered to each other in end to end relation by the natural fluids freed from the meat by cutting and extrusion forces. The amount of cereal is thoroughly impregnated by the freed juices, leaving an excess of freed juices only sufficient to adhere the food particles together and moisten the extrusion. The freed juices of the meat, and supplement, if any, are substantially the only moisture present.
