Title: Stent having a programmed pattern of in vivo degradation
Inventor: CORNHILL FREDERICK
IPC: A61F2/92
Filed: 1998-12-15
Abstract: The present invention provides a biodegradable polymeric stent having a programmed pattern of in vivo degradation. When deployed, the stent comprises at least one substantially cylindrical element having two open ends and a plurality of regions circumferentially spaced around the cylindrical element and extending from one open end to the other open end of the cylindrical element. Each of the regions is configured or designed to have a desired in vivo lifetime.  At least one of the regions is designed to have a shorter in vivo lifetime than the other region or regions so that when the stent is deployed within the lumen of a vessel of a patient, the cylindrical element acquires one or more fissures which extend from one open end of the cylindrical element to the other open end of the cylindrical element within a desired, predetermined period of time after the stent is deployed in the patient. In one preferred embodiment the stent is a formed from a biodegradable polymeric band comprising a head having a slot and a tongue comprising a catch or locking mechanism proximate the longitudinal edge thereof. The cylindrical element which has an inner and outer surface is formed by inserting a portion of the tongue through the slot to provide a cylindrical element having a first reduced diameter configuration. Following deployment, the cylindrical element is in a second expanded diameter configuration wherein the distal catch mechanism engages the inner surface of the head and prevents radial collapse or recoil of the polymeric stent. In a second preferred embodiment, the stent is formed from a plurality of interconnected polymeric bands each of which comprises a head having a slot and a tongue comprising a catch mechanism proximate the longitudinal edge thereof. The present invention also relates to a method of mounting the stents of the present invention on a balloon catheter. The method comprises heating the stent to temperature above the glass transition temperature of the polymer used to form the stent positioning the stent on a deflated balloon mounted on a catheter, and compressing the stent to a reduced diameter configuration to secure the stent to the balloon. The present invention also relates to an assembly which comprises the stent of the present invention mounted on a balloon catheter.

Title: Antenne de substrat comportant un element de prevention de couplage d'energie entre antenne et conducteurs
Inventor: SEE PUAY HOE
IPC: H04B1/38
Filed: 1999-02-18
Abstract: L'invention concerne un brin parasite (800, 900) destiné à s'utiliser avec une antenne intérieure (300) dans un dispositif sans fil (100, 700). En général, l'antenne est une antenne de substrat (300) comprenant un ou plusieurs tracés conducteurs (302) disposés sur un substrat (304) et montés en décalage par rapport à un plan de masse (504, 508) associé au dispositif sans fil. Un ou plusieurs conducteurs, câbles ou sources de signaux (712) de transfert de signaux ou d'énergie sont disposés à proximité immédiate de l'antenne (300) et sont capables de coupler des signaux dans l'antenne qui tire l'énergie provenant des champs alentour ou émanant des conducteurs. Dans un autre mode de réalisation, les conducteurs interceptent une partie de l'énergie transférée dans l'antenne (300). Le brin parasite de connexion (800, 900) fait appel à une structure conductrice mince placée à côté, au-dessus ou au-dessous des conducteurs (712) pour réduire sensiblement l'énergie provenant du couplage entre les conducteurs et l'antenne en modifiant les caractéristiques de couplage par résonance ou de couplage énergétique des conducteurs. Le brin parasite (800, 900, 902, 904, 906) empêche le transfert d'énergie entre les conducteurs et l'antenne, ce qui augmente le gain total du dispositif. En outre, le brin parasite et le couplage parasite du brin parasite au plan de masse permet d'augmenter le gain et la largeur de bande des dispositifs sans fil. Le brin parasite peut être formé de plusieurs matières et peut présenter plusieurs formes (800, 900, 902, 904, 906) et on peut le mettre en place par plusieurs techniques connues de placement et de mise en place de couches de matière conductrice mince ou métallique.

This method allows the printing of small identification characters on wafers using the stepper technology.
Patent CA-2322908-A1 (CA)
Title: Semi transparent tributary for synchronous transmission
Inventor: MURTON CHRIS
IPC: H04Q11/04
Filed: 2000-10-06
Abstract: An interface for converting a variety of incoming digital signals into SDH/SONET format for transmission on a synchronous digital network, by identifying the line code of the incoming digital signal, without identifying the information for OSI layer 2 or 3 processing, i.e. format of each packet. Headers are used to encapsulate incoming packets, and enable packets to be discriminated at the receiver. Advantages of performance monitoring capability and transparency are combined. Identifying line codes enables a greater degree of error detection, than a bit based interface. Also synchronisation can be simpler since line codes for padding can be added or deleted more easily than adding or subtracting bits. The interface is semi--transparent in the sense that identification of line codes limits the interface to those formats that use identifiable line codes, but without limiting to a particular OSI layer 2 or 3 frame format.

Patent CA-2334418-A1 (CA)
Inventor: KAYSER ROY
IPC: H05B41/392
Filed: 2001-02-07
Abstract: The invention relates to a power supply for an illumination system used to expose photo-initiated adhesives. The illumination system includes an arc lamp to provide light. As the lamp ages, its electrodes deteriorate, reducing the amount of light directed into a light guide and ultimately onto the adhesive. The power supply provides an increasing power input to the lamp to increase the light output of the lamp, countering this deterioration at least in part. The voltage and current drawn by the lamp are measured and a skewed control signal which magnifies the level is used to control the power input to the lamp.

Inventor: O'BRIEN MICHAEL E
IPC: B41J21/00
Filed: 1999-08-12
Abstract: Printed articles such as flag or tab media can be printed with text and/or graphic objects specified by a user. The flag or tab media are useful in marking and indexing functions. The printed text and/or graphic objects can enhance the communicative and organizational effects of the tab or flag medi a, conveying information indicative of order, sequence, or identification. The flag or tab media can be arranged on a print sheet that is fed into a deskto p printer. The layout of the flag or tab media on the print sheet can necessitate "upside-down" printing of the objects in certain areas to achiev e an appropriate orientation during use, particularly for folded or inverted media. In this manner, the orientation of an object is flipped according to its position on the media. A design application program executed by a computing system allows an end user to design objects on flag or tab media without worrying about the necessary flipping functions. The application automates the flipping functions, and incorporates them into the workflow of  the design process.
