Abstract: An apparatus for exposing and developing a sheet of light-sensitive material, said apparatus comprising an optical image-producing system consisting of an original plane (10), an objective plane (8), and an image plane (6), and a developing station (18, 20), whereby the sheet of light-sensitive material can be advanced after the exposure in the image plane (6) to the developing station (18, 20) so as to be developed. The apparatus comprises further an image-setter (22, 22') placed adjacent, preferably below the image plane of the optical image-producing system, and guiding means (24) for advancing the material exposed by the image-setter to the developing station (18, 20). The image-setter can be placed in the usually unutilized cavity below the optical system. In addition, the apparatus allows several possibilities of use. It turned out that the same developing station can be used. The image-setter can optionally be adapted to expose selected portions of the light-sensitive material, which can subsequently be exposed by means of the optical image-producing system. In this manner some portions of a sheet of light-sensitive material are exposed by means of the image-setter, whereas other portions of said material can be exposed by means of the optical image-producing system. As a result, the apparatus is more universal than previously known.

Abstract: Heterostructure laser diodes with active region comprising a quaternary semiconductor compound, the composition of the semiconductor compound of said active region being modulated. This modulation results in an active region having a modulated strain profile (Δa/a), e.g. a triangular sawtooth-like strain profile, perpendicular to the laser diodes' epitaxial layers, i.e. parallel to a z-axis. The main idea of the present invention is to further increase the strain and to avoid formation of misfit dislocations by compensation, i.e. by inserting strained layers with opposite strain.

Abstract: A line spectral frequency (LSF) vector quantizer, having particular application in digital cellular networks (DCN), is provided for code excited linear predictive (CELP) speech encoders. The LSF vector quantizer is efficient in terms of bits employed, robust and effective in terms of performance across speakers and handsets, moderate in terms of complexity, and accommodates effective and simple built-in transmission error detection schemes. The LSF vector quantizer employs a minimum number of bits, is of moderate complexity and incorporates built-in error detection capability in order to combat transmission errors. The LSF vector quantizer classifies unquantized line spectral frequencies into four categories, employing different vector quantization tables for each category. Each quantization table is optimized for particular types of vectors. For each category, three split vector codebooks are used with a simplified error measure to find three candidate split quantized vectors. The three sets of three split vectors are combined to produce as many as 27 vectors from each category. The quantizer then makes a final selection of optimal category, using a more complex error measure, to achieve the robust performance across speakers and handsets. Split vector quantization follows a two stage constrained search procedure that results in an ordered set of quantized line spectral frequencies that is "close" to the unquantized set with moderate complexity within each category. Effective and simple transmission error detection schemes at the receiver are made possible by the split nature of the vector quantization and the constrained search procedure. Only twenty-six bits are required to encode ten line spectral frequencies.

Title: Fiber optic cable monitoring system.
Inventor: VOKEY DAVID E
IPC: G01M11/08
Filed: 1993-04-08
Abstract: The invention provides a monitor for monitoring the condition of fibre optic communication cables. The system employs one or more of the optical fibres of a cable to monitor the cable structure for damage or kinks. By using two separate laser sources and simultaneously monitoring the optical losses at two distinct and separate wavelengths, the loss signature of the monitored fibre is determined, analyzed and related to the mechanical condition of the cable structure. To monitor splice points for moisture, a special optical splice sensor unit detects any penetration of water into the splice and transmits a coded alarm signal over the monitored fibre to the optical receiver. Every splice location is assigned a unique sensor code. The optical splice sensor is driven by moisture detection cell, which forms a single cell water activated battery. Water entering the monitored splice closure wets the tape, which activates the cell. The cell generates sufficient voltage and current to power timing, code generation and modulator circuits in the sensor unit for an extended period of time. The activated circuit drives a modulator which modulates the light travelling down the fibre. The modulated light is monitored at the equipment office and the address of the alarming sensor decoded.
