Title: Automatic segmentation of nystagmus or other complex curves
Inventor: SMITH HEATHER L
IPC: A61B5/00
Filed: 1999-02-17
Abstract: For segmenting a sampled signal having at least two temporally separate interleaved dominant components for the purposes of extracting one or more of the separate components, an automated method of analyzing the sampled signal is used. By selecting a model for the signal and a processing window dimension, a variance between the signal and a model value for the signal is measured within the window over the sampled domain to obtain a noise indicator value. A corner geometry value for the sampled signal is calculated within the same window over the domain. A  transition indicator value is generated based on a ratio of the corner geometry value and the model value. The segmentation points are identified based on the transition indicator value and at least one of the noise indicator value and the model value within the window over the domain.

Title: Polarizing back-lighting system for direct view liquid crystal displays
Inventor: LI LI
IPC: F21V8/00
Filed: 1999-11-25
Abstract: A polarizing light source for providing polarized illumination over a two- dimensional surface has a slab-like light guide with an entrance face at one end thereof for admitting unpolarized light from a linear source, a planar front face for emitting polarized light, a planar back face, and an end face. A polarizing device is located on said back face for reflecting light of a first polarization and transmitting light of a second polarization at non-normal angles of incidence. The reflected light is directed in the light guide to the end face. A reflective arrangement under the polarizing device returns the transmitted light to the light guide in a direction substantially normal to the polarizing device such that it passes unaffected through the polarizing device for exit through the front face. A polarization converter on the end face changes the polarization of the reflected light and directs it into the reflective arrangement through the polarizing device as light of the second polarization for return to the light guide through the polarizing device in a direction substantially normal to the polarizing device such that it passes unaffected through the polarizing device from the reflective arrangement for exit through said front face.

Patent CA-2308014-A1 (CA)
Inventor: BABINSKI KAZIMIERZ
IPC: C12N15/12
Filed: 1998-10-29
Abstract: Small changes of extracellular pH activate depolarizing inward currents in most nociceptive neurons. It has been recently proposed that acid sensitivity of sensory as well as central neurons is mediated by a family of proton-gated cation channels structurally related to C. elegans degenerins and mammalian epithelial sodium channels. We describe here the molecular cloning of a novel human proton receptor, hASIC3, a 531 amino acid-long subunit homologous to rat DRASIC. Expression of homomeric hASIC3 channels in Xenopus oocytes generated biphasic inward currents elicited at pH 5, providing the first functional evidence of a human proton-gated ion channel. Contrary to the DRASIC current phenotype, the fast desensitizing early component and the slow sustained late component differed both by their cationic selectivity and by their response to the antagonist amiloride, but not by their pH sensitivity (pH50= 3.66 vs 3.82). Using RT-PCR and mRNA blot hybridization, we detected hASIC3 mRNA in sensory ganglia, brain and many internal tissues including lung and testis, so hASIC3 gene expression was not restricted to peripheral sensory neurons. These functional and anatomical data strongly suggest that hASIC3 plays a major role in persistent proton-induced currents occurring in physiological and pathological conditions of pH changes, likely through a tissue-specific heteropolymerization with other members of the proton-gated channel family.
