Title: Wire fault detection
Inventor: BECHHOEFER ERIC ROBERT
IPC: G01R31/311
Filed: 2004-01-13
Abstract: Described are techniques used in a wire diagnostics system to detect events, such as defects, that may occur within a wire or cable under test. An incident voltage signal is sent out on the wire and a measured voltage signal is obtained which includes the incident voltage and the reflected voltage. Compensation processing is performed on the measured waveform to remove unwanted reflective components. Additionally, the waveform is then subject to attenuation processing and event detection processing. Detected events, such as defects, are classified and output as results. Events are classified by parametric classification using a library of known events or faults. The library of known events or faults is previously generated using empirical analysis and modeling techniques. Additionally, joint time-frequency domain reflectometry (TFDR) techniques are described for event identification and classification for a wire under test.

Patent CA-2457588-A1 (CA)
Inventor: KUHS BERND
IPC: B22C1/18
Filed: 2002-07-16
Abstract: The invention relates to the production of molds or cores (2) for foundry purposes, wherein a mixture (3) of foundry sand and binder are produced and introduced into a mold or core tool (8), e.g. shot in a core shooter. A known binder or magnesium sulfate with and/or without at least one or additionally several crystallization waters is dispersed or dissolved in water and used as binder, which is then mixed with the foundry sand and introduced or shot into the mold tool or the core box (8). For hardening purposes, the water and a fraction of the crystallization water are vaporized by heating and driven out by a gaseous medium, all of which can be carried out very rapidly. After pouring, said core or mold consisting of foundry sand can be very rapidly removed from the tool with water and flushed due to the fact that the magnesium sulfate preserves its capability of dissolving.

Title: Backlighting system for displays
Inventor: WANG SAN ZHUANG
IPC: B29C41/12
Filed: 2003-07-26
Abstract: An LED-based backlighting system that provides excellent brightness and homogeneity suitable for high performance multi~color and high resolution portable displays such as for PDAs and cell phones. Several different but similar embodiments are disclosed. Some are suitable for use with multiple LEDs (30) and some for use with a single LED (12). In a first such embodimen t, multiple LEDs are located adjacent the input edge of a light pipe (14). The input edge contains fixed pitch grooves to propagate the LED light in a direction that is substantially angled toward the bottom surface of the ligh t pipe along its entire area. The light pipe (32) bottom surface also has grooves for altering the direction of the LED light toward the upper surface of the light pipe where it exits the light pipe toward a viewer. The exterio r of the exit surface of the light pipe receives a light shaping diffuser (LSD ) and an optical film (48). The diffuser (42) acts to diffuse and distribute t he exiting light at selected horizontal and vertical angles and the optical fil m shapes. In a second embodiment, a second LSD is positioned above the optical film. In a third embodiment, an LSD strip comprising a foreshortened LSD is positioned below the light pipe adjacent the input edge to better reduce hot spots near the LEDs.
