Title: Data transaction card and method of manufacture thereof
Inventor: GILBOA RONNIE
IPC: G06K19/077
Filed: 1998-11-09
Abstract: A data transaction card having an interface for bi-directional contactless communication, and comprising a support (20) having a cavity (12) for accommodating therein a chip carrier module (10). The chip carrier module comprises a substrate (11) having a first side (45) and a second side (46), and an integrated circuit (30) mounted on the first side of the substrate for managing functions of the data transaction card. A coil antenna (40) is electrically connected to the integrated circuit for inductive coupling with a remote antenna, connections to the coil antenna being accessible from the first side of the substrate. The chip carrier module is packaged into one discrete unit so as to be amenable to mechanical assembly of the data transaction card without requiring additional electrical connections between the support and the chip carrier module during or subsequent to assembly. Such a construction allows for efficient mass-production of the data transaction card.

Title: Device and method for the gripping and retention of part of a split carcass by the spinal column
Inventor: POST ERLING
IPC: A22B5/00
Filed: 2000-06-09
Abstract: The invention concerns a device for the gripping and retention of part of a split carcass by the spinal column (17), and the conveyance of that part essentially in the lengthwise direction of the spinal column, while retaining it by the spinal column during processing of the carcass part by means of cutting tools. The device comprises a mainly rectilinear conveyor (10) with retention elements (11) connected as links in an endless chain, with each element having a first section (21) with a contact surface (22) for a first side of the spinal column and a second section (25) with a pressure surface (26) for a second side of the spinal column. The two sections of each element are designed to allow the contact surface (22) and the pressure surface (26) to be relatively moved towards and away from each other in a direction across the conveyor's direction of conveyance. The spinal column can be gradually gripped and clamped between the surfaces (22, 26) when the contact surface (22) and pressure surface (26) are successively, element by element, moved towards each other. The device provides a firm grip between the spinal column and the machine parts of an apparatus for processing of e.g. fore-ends or middles.
Patent CA-2313357-A1 (CA)
Inventor: LABRANCHE BRUNO
IPC: G02B6/36
Filed: 2000-07-04
Abstract: A microlens holder for supporting at least one microlens in alignment with  a light source is described. Each of the microlenses has a radius and a back focal length varying linearly with the radius. The microlens holder includes  a base having at least one V-groove therein for receiving the at least one microlens, each of the V-grooves having a pair of side walls, both side wall s being tilted by an angle 8 relative to the plane of the emitting light sourc e. The value is defined by the relationship cos(8) _ (1 + k)-1, where k is a positi ve constant factor associated with the at least one microlens. The microlens holder allows auto-focussing of the light source, independently of the exact diameter of the microlenses mounted in the holder. The optical alignment of the microlenses is made easier as well.

Title: Cervical extrication collar
Inventor: KOLEDIN MICHAEL JANIS
IPC: A61F5/00
Filed: 1999-01-14
Abstract: An emergency extrication collar comprising a flexible band for encircling the wearer's neck, and a chin support member which may be readily adjusted in elevation with respect to the band so as to permit adjustment to fit patients having varying neck sizes. The chin support member is connected to the band by means of a post which is slidably connected to a vertical strap on the band, and such that the elevation of the chin support member above the post, and thus the neck size of the collar, may be adjusted by simply sliding the post and chin support upwardly to any selected size between the size extremes. A  pawl and ratchet interconnection between the post and strap precludes movement in the opposite direction. The collar is secured in its adjusted size by means of a locking arm which is pivotally mounted on the post, and movement of the locking arm to its release position also releases the pawl and ratchet interconnection.

Title: A method of fabricating mirrors in polymer waveguides
Inventor: ROBERTSSON MATS
IPC: G02B6/26
Filed: 1999-03-08
Abstract: The position of an oblique mirror structure inside a polymer waveguide (1) in relation to an optical device is accurately defined by using an integrated mask of metal which is defined using photolithography, on top of the waveguide structure. When irradiating the surface of the waveguide with laser light, it is only let through where no metal is left, so that the recess (19) formed is defined by edges of strips (15) of the metal layer. In the same metal layer also electrical contact pads (13) are produced used for self-aligning flip-chip mounting of devices such as lasers and photodiodes. Another metal layer (21) can be applied inside the waveguide structure at a place under the waveguide core so that it is hit by and stops the laser light. The energy of the laser will atomize the metal and the dispersed metal will then be deposited on the walls of the recess (19).

Title: Noise/interference suppression system
Inventor: YEAP TET HIN
IPC: H04L27/26
Filed: 2000-11-24
Abstract: A noise suppression circuit for a communications channel (12) comprises a noise reference extraction device (14), for example a hybrid transformer or circuit, for extracting from an input signal (S) a reference signal (N CM) corresponding to a noise component in the input signal and supplying the noise reference signal to a noise estimation unit (16) which derives therefrom a noise estimate (Y j) which is subtracted from the input signal to produce a noise-suppressed output signal (D OUT). The noise suppression circuit comprises a first analog-to-digital converter (24) for digitizing the input signal at a first sampling rate (Fs) and a second analog-to-digital converter for sampling the noise reference signal (N CM) at a second, lower sampling rate (FS/M), the ratio (M) between the two sampling rates being an integer. A decimator (40) decimates the input signal to produce a decimated signal (D j+N j). An adaptive filter (34) produces a noise estimate signal (Y'j) that is subtracted from the decimated signal to produce an error signal (.epsilon.j) which is used by adaptive filter (34) to adjust its coefficients. An interpolator (36) interpolates the interim noise estimate signal (Y'j) by the same integer (M) to provide a noise estimate signal (Y j) which is subtracted from a digitized and delayed version of the input signal to produce the noise-suppressed output signal (D OUT).
