Title: Quantization of Input Vectors with and Without Rearrangement of Vector Elements of a Candidate Vector
Inventor: SERIZAWA MASAHIRO
IPC: G10L19/08
Filed: 1995-04-20
Abstract: For quantizing input vectors into output codes with reference to quantization vectors with reduction of a memory capacity, a vector quantizer device comprises a rearranging unit (21, 23) between a codebook circuit (17) preliminarily loaded, in accordance with codebook indexes, with code vectors selected from the quantization vectors to produce at least one candidate vector in response to a current index and a distance calculator (15) for calculating, between each input vector and comparison vectors given by the candidate vector, distance values for supply to an evaluation circuit (19) for producing a selected index indicative of one of the comparison vectors that minimizes the distance values and for successively producing the output codes with the selected index used as each output code without or with addition of a rearrangement index.      When the rearrangement index is and is not added, the rearranging circuit produces the candidate vector in each comparison vector as an unchanged vector and as a rearranged vector in which vector elements of the candidate vector are rearranged, respectively. The rearranging unit may rearrange the candidate vector in compliance with a single predetermined rule or with rules preliminarily stored in a rearrangement table circuit (23) in accordance with table indexes with one of the rules delivered to a rearranging circuit (21) in response to the rearrangement index.

Title: Self-contained emergency eye wash station
Inventor: DEMENY RODNEY L
IPC: A61H35/02
Filed: 1996-05-22
Abstract: A self-contained emergency eye wash station for dispensing eye wash fluid contained in a flexible container comprises a housing, a reservoir, and a platen. The housing supports the flexible container and supports a nozzle in fluid communication with the flexible container. The nozzle dispenses the eye wash fluid from the flexible container. The housing includes a drain capturing the eye wash fluid dispensed from the nozzle. The reservoir collects the eye wash fluid captured by the drain, and the reservoir is slidably mounted to the housing. The platen is connected to the reservoir. The platen is slidably movable relative to the housing and is located immediately above the flexible container. The platen presses downward on the flexible container with a downward force proportional to a weight of the eye wash fluid collected in the reservoir. The transfer of the weight of the eye wash fluid collected in the reservoir to the platen maintains a constant flow of eye wash fluid dispensed from the nozzle.

IPC: G02B6/42
Filed: 1996-06-19
Abstract: A balanced focus system and method achieve optimal focus of different areas of an object that are concurrently imaged and then combined to form a combined image. The balanced focus method is particularly suited for, but not limited to, use with an automatic inspection system for contactlessly measuring at an endface of an optical fiber termination the eccentricity of an optical fiber core relative to a theoretical ideal center of an alignment surface of the termination. The inspection system has an imaging system with a feature imager and one or more boundary segment imagers but preferably four in number, a focus adjustment mechanism (FAM) for adjusting the position of the imagers relative to the imaged object along an optical axis, and a machine vision system for receiving image data from the foregoing imagers and configured to control the FAM. The feature imager is positioned to capture an image of the feature (e.g., fiber core endface), and the one or more boundary segment imagers are positioned to capture an image of a corresponding boundary segment of the object (e.g., termination endface). The machine vision system determines the eccentricity based upon the feature image and the one or more boundary segment images. Significantly, the machine vision system employs the balanced focus system and method to achieve an optimal focus position for the imaging system based upon a series of combined images and a statistic S that is computed for each of the sampling locations.
