Granted: 1992-02-04
Abstract: ABSTRACT OF THE DISCLOSURE      Test compositions and test device are pro-vided which are capable of generating different hues at different analyte concentrations.  The compositions are capable of generating a yellow hue in situ. Visual tests for clinically important analytes, such as glucose, are deter-mined by use of two independent catalytic systems which are reactive with reduced nicotinamide adenine dinucleotide to produce a range of hues; the particular hue produced depending on the concentration of the analyte.  The invention provides a test device for the determination of analyte, e.g. glucose, in body fluid which exhibits a RAINBOW of hues, the particular final hue produced depending on the analyte concentration.

Abstract: ABSTRACT   A method for forming a vehicle window assembly includes applying a band of an opaque ceramic enamel material to a predetermined peripheral portion of a sheet of relatively flat glass, and heating the glass to a prefire temperature to fuse the opaque material to the glass.  An electrically conductive material is applied to the band in a predetermined pattern to form a pair of bus bars typically along the top and bottom edges of the sheet of glass.  The glass is again heated to fire the bus bar material and soften the glass for bending into a desired window shape.  A mask is applied to the bus bars for later connection of electrical leads and the sheet of glass is washed prior to the next operation.  An electrically conductive film is applied to the second surface of the sheet of glass and electrically connected to the bus bars.  The sheet of glass is laminated to a sheet of plastic material which covers the electrically conductive film and, typically, the plastic sheet is laminated to a second sheet of glass which has been preformed, ie., bent, to conform to the first sheet. Electrical leads are attached to the bus bars to complete the window assembly.  The electrically conducting film and glass sheet composition and thickness are chosen to maximize for the window assembly the desired performance characteristics of resistance, transmission, reflection and color - all of which are mutually interactive.

IPC: G10L25/93
Filed: 1988-05-16
Granted: 1995-07-25
Abstract: Apparatus for encoding speech using an improved code excited linear predictive (CELP) encoder using a virtual searching technique to improve performance during speech transitions such as from unvoiced to voiced regions ofspeech. The encoder compares candidate excitation vectors stored in a codebook with a target excitation vector representing a frame of speech to determine the candidate vector that best matches the target vector by repeating a first portion of each candidate vector into a second portion of each candidate vector. For increased performance, a stochastically excited linear predictive (SELP) encoder is used in series with the adaptive CELP encoder. The SELP encoder is responsive to the difference between the target vector and the best matched candidate vector to search its own overlapping codebook in a recursive manner to determine a candidate vector that provides the best match. Both of the best matched candidate vectors are used in speech synthesis.

Granted: 1991-11-26
Abstract: COMPUTATIONAL ORIGAMI Abstract A processor architecture that permits the realization of any computing function with a regular array of interconnected processing elements comprising as few as one processing element. The processing element can be as complex as desired. In its minimum form it can be as simple as a NOR gate and a switch coupled with some delay elements, with the connectivity and the control signals combining to impart the flexibility. In use, an algorithm to be implemented is conceptually mapped onto an array of processing elements arranged in rows and columns, where the data dependencies in the columns are unidirectional, and the data dependencies in the rows of processing elements are at most unidirectional.One or more actual processing elements are conceptually scanned over the array through time multiplexed controls to emulate the entire conceptual array and thus perform the algorithm. The scheduling of the processing and communications functions performed by the processing element is dictated by the conceptual array layout of the algorithm.
