Patent CA-2319729-A1 (CA)
Title: Birefringence measurement system
Inventor: WANG BAOLIANG
IPC: G01N21/23
Filed: 1999-02-17
Abstract: A practical system and method for precisely measuring low-level birefrigence properties (retardance and fast axis orientation) of optical materials (26). The system permits multiple measurements to be taken across the area of a sample to detect and graphically display (100) variations in the birefrigence properties across the sample area. In a preferred embodiment, the system incorporates a photoelastic modulator (24) for modulating polarized light that is then directed through a sample (26). The beam ("Bi") propagating from the sample is separated into two parts, with one part ("B1") having a polarization direction different than the polarization direction of the other beam part ("B2"). These separate beam parts are then processed as distinct channels. Detection mechanisms (32, 50) associated with each channel detect the time varying light intensity corresponding to each of the two parts of the beam. This information is combined for calculating a precise measure of the retardance induced by the sample, as well as the sample's fast axis orientation.

Title: Filter for a tray, sterile tray arrangement and method of manufacturing same
Inventor: OBERDORFER HARALD
IPC: A61L2/26
Filed: 1998-03-06
Abstract: The invention relates to a filter (1) made of a flexible flat material (2), comprising at least one seal (3) which is firmly fixed to the flat material (2) and extends along a closed line. Said seal (3) runs along an edge area of the flat filter material (2).  To produce the filter (1) provided for in the invention, a linearly closed seal (3) is deposited by means of a foaming device on the flat material (2) which is held by a device. After application the seal is polymerised and so becomes joined to the flat material (2). To use the material in medical trays, the flat filter material (2) must be such that no micro-organisms are able to penetrate it. To arrange such a filter (1) on a partial tray surface having through openings in such a way as to provide a seal which ensures sterility, it is sufficient to configure a closed sealing line which extends around the through openings, and to fix the seal (3) of the filter (1) along the line tray parts to be connected with cooperating compression surfaces. Thanks to the elasticity of the seal (3) a sufficiently good joint is obtained even with low compression pressure and if the compression surfaces are not absolutely even.  A further advantage of the joint between the seal (3) and the flat filter material (2) is that the filter (1) can also be arranged on a lower side if the seal (3) is pressed into a corresponding groove, without it becoming detached from said lower side due to gravity.

Abstract: A cookware system includes a cooking vessel, a multipurpose cookware cover for covering the cooking vessel and serving food prepared in the vessel, and a storage lid engageable with the cookware cover to seal in food placed in the cookware cover for storage. The multipurpose cookware cover includes a support member that extends from the cover body and terminates in a plurality of contact points disposed in a common plane. Thus, when the cookware cover is inverted and set upon a flat surface for use as a serving dish or storage container, the contact surfaces of the support member contact the flat surface and prevent the cookware cover from wobbling. The body of the multipurpose cookware cover may be made of a plastic material. A heat-resistant rim disposed about the peripheral edge of the cover body insulates the cover body from heat that may be conducted through a cooking vessel.

IPC: G01M3/28
Filed: 1999-05-07
Abstract: A liquid flow control valve has a valve body (10) in which is mounted a valve member (41) moveable between valve open and closed positions. A turbine (15) senses liquid flow through the valve body (10) and generates electrical pulses which are counted by a control circuit, over a pre-set period. An electro-magnet (54, 55) controls operation of the valve member (41) and is driven by the control circuit so as to close the valve in the event that flow continues for longer than the pre-set period or the flow is greater than at a pre-set rate. The valve may also be closed should the temperature fall to about 0°C.

Title: X-ray pixel detector device and fabrication method
Inventor: PETERSSON STURE
IPC: G01T1/20
Filed: 2000-01-21
Abstract: A method and a device are disclosed for producing an X-ray pixel detector, i.e. an imaging detector for X-ray photons, the detector presenting high efficiency combined with high resolution for obtaining a high image quality detector while at the same time minimizing the X-ray dose used. The application is particularly important whenever the X-ray photon absorption distance is much longer than the required pixel size. The arrangement according to the present invention presents a structure based on light-guiding of secondarily produced photons within a scintillating pixel detector in conjunction with, a CCD or a CMOS pixel detector. The structure according to the invention presents a matrix (8) having deep pores (10) fabricated by high-aspect ratio silicon etching techniques producing very thin walls and with a pore spacing less or equal to the size of a pixel (2) of the image detector used. The pore matrix is subsequently filled by melting a scintillating material into the pores such that, in each pore, a single scintillating block is formed. The silicon matrix (8) may further utilize a reflective layer to increase light guiding down to the image detector chip.

Abstract: The present invention relates to a high-sensitivity top-electrode and bottom-illuminated type photodiode. The device consists of a highly doped buffer layer, a photo-detecting layer on a semi-insulating substrate. An electrode is formed on the conductive domain that is formed in the photo-detecting layer, and another electrode is formed on the partly exposed peripheral area of the highly-doped buffer layer by removing a part of the photo-detecting layer. As the semi-insulating substrate absorbs less light in the substrate, a decrease of sensitivity by the substrate absorption can be prevented.

Title: Stent having a multiplicity of undulating longitudinals
Inventor: FISCHELL TIM A
IPC: A61F2/82
Filed: 1995-02-20
Abstract: The present invention provides for an expandable stent for use in an artery or other vessel of a human body. The stent structure maintains the patency of the vessel within which the stent is expanded radially outward. One embodiment of the present invention is a stent having a multiplicity of frames joined together by at least two undulating longitudinal structures which can readily change their length in the longitudinal direction so as to provide increased longitudinal flexibility for the stent for easy passage through and placement within a curved vessel such as a coronary artery. The stent is an embodiment of the present invention having frames joined with longitudinal structures and formed from a single, thin- walled piece of metal by means of laser cutting or chemical etching. Because the stent is fabricated from a single piece of metal, it provides a multiplicity of closed perimeter cells that are formed as a continuous metal structure.
