Patent CA-2377377-A1 (CA)
Inventor: CHERTKOW IGAL ROBERTO
IPC: G02B6/35
Filed: 2000-02-10
Abstract: A microelectromechanical system (MEMS) optical switch is introduced which includes a mirror (1) constructed on a substrate (2). The mirror (1) is movable parallel to the surface of the substrate (2) and either allows an input ray incident at an oblique angle, preferably 45~, to the mirror surfac e to pass undisturbed through a transparent part (49) of a substrate (2) or reflects the ray to an alternate output. Three embodiments of the switch are  shown. The first includes a variation on a comb-drive designed to produce larger forces than usual by using an envelope-like electrode into which the mirror (1) is drawn. Larger forces can be obtained by designing the electrod e edges to have a long perimeter line, such as in a fractal form. A second implementation supports a mirror (1) on flexible beams which are attracted o r repelled by electrostatically charging curved electrodes thereby actuating t he mirror. In a third implementation, a magnetic field around the switch induce s lateral forces when electric current flows in conductive supporting beams to  cause switching.

Abstract: There is disclosed a cable actuated truss - 4 degrees of freedom (CAT4) robot. The robot is a novel, passively jointed, parallel robot utilizing six control cables for actuation. The robot utilizes a passive jointed linkage with 18 revolute joints to constrain the end effector motion and provide the desired structural stability, restricting the end effector to 3 translational degrees of freedom (DOF) and 1 DOF for end effector pitch. This central mechanism together with winched cable actuation gives a number of important benefits for applications where the advantages of a parallel robot are required in conjunction with light weight.  Six electric motor driven winches control the length of the cable actuators that extend from the top frame to points on the end effector raft and jointed linkage to create a stiff, but lightweight, actuated robot.

Title: Anti-inflammatory actions of cytochrome p450 epoxygenase-derived eicosanoids
Inventor: LIAO JAMES K
IPC: A61K31/325
Filed: 2000-08-10
Abstract: Epoxyeicosatrienoic acids (EETs) are products of cytochrome P450 epoxygenase s that have vasodilatory properties similar to endothelium-derived hyperpolarizing factor (EDHF). The cytochrome P450 isoform CYP2J2 was cloned  and identified as a source of EETs in human endothelial cells. Physiological  concentrations of EETs or overexpression of CYP2J2 decreased cytolcine-induc ed endothelial cell adhesion molecule expression and prevented subsequent leukocyte adhesion to the vascular wall by a mechanism involving inhibition of transcription factor NF-.kappa.B and I.kappa.B kinase (IKK). The inhibitory effects of EETs were independent of their membrane hypopolarizing effects suggesting that these molecules play an important non-vasodilatory role in vascular inflammation.

IPC: G06F17/30
Filed: 2002-07-26
Abstract: An optical device for the dynamic compensation of chromatic dispersion allowing a wide range of dispersion correction levels is disclosed. It is based on the combination of a series of optical structures each including a waveguide and a Bragg grating provided therein. The Bragg gratings have an intrinsic chirp allowing the relative delay of wavelength components in order to compensate the chromatic dispersion components. The various arrangement of the grating orientations results in different ranges of dispersion compensation levels, depending on the relative accordance of the chirp period of each grating component. Dynamic chromatic dispersion compensation is obtained by tuning the optical structure by means of a grating control unit coupled to the fiber grating.
