Title: Tubular grafts from purified submucosa
Inventor: FEARNOT NEAL E
IPC: A61F2/06
Filed: 1997-12-10
Abstract: An easy-to-produce and mechanically strong tube of an implantable graft prosthesis has been developed which is manufactured in any desired length, wall thickness, or diameter. The construct produced by the method of the invention may be used as grafts for arteries, vein, ureters, urethras, shunts, or in any application where a compliant, tissue-compatible tube is needed. The manufacture of the graft prosthesis generally involves wrapping multiple sheets of a purified, collagen-based matrix structure around a mandrel, compressing and drying the tissue on the mandrel before removing the construct for eventual use.
Patent CA-2275261-A1 (CA)
Inventor: DENIS JACQUES
IPC: C25D17/28
Filed: 1997-12-10
Abstract: The invention concerns a method for the precise electrolytic deposition and etching of metals into the edge region of circuit boards and conductor foil panels in a continuous system. In continuous systems, the panels are gripped at least at an edge by clamps. The clamps are used to supply current to the panels and possibly also to convey them. Very great differences in layer thickness are produced in the panel edge region, inter alia owing to the screening effect of the clamps. This edge region cannot be used for highprecision circuit boards. The invention enables the layer thickness distribution in this edge region to be improved in that the system is separated into a plurality of partial regions and in each case the clamp gripping points in one part of the system are offset (V) in a specific manner relative to those in another part of the system. The offset is preferably set at values corresponding to the quotient of the clamp spacing (T) and the number of successive system parts. The spacing is maintained constant by electrical or mechanical measures.

Title: Distributed pbx/centrex and pots service over atm/xdsl
Inventor: GETCHELL WAYNE
IPC: H04Q3/62
Filed: 1999-07-06
Abstract: The present invention relates to telecommunication systems that facilitate distributed access to voice and data communications (in particular PBX/Centrex and POTS services). A gateway is connected to a PBX or Centrex switch which puts speech and call control signals originating from the PBX or Centrex switch into Asynchronous Transfer Mode (ATM) cells and sends them to an ATM network. The ATM network transports the cells to a Digital Subscriber Loop Access Multiplexer (DSLAM). The DSLAM provides an interface between the ATM network and a Digital Subscriber Loop (DSL) channel connected to the customer premises. A      Customer Premises Equipment (CPE) reconstitutes the speech and call control signals and sends them to a telephone set and/or computer device attached thereto. Since the speech samples and call control signals originate with the customer's PBX or Centrex switch, the telecommuter and/or small branch office can use the same telephone set, same dial plan, same call features and same low-cost long-distance calling plan as colleagues back at the head office.

Inventor: POTTECK SERGE
IPC: G01C1/00
Filed: 1998-02-13
Abstract: The invention concerns the identification of stars. It consists in selecting "detected stars" among the sensed stars; coupling the detected stars; selecting all or part of the doublets of the catalogue which are most likely to have been present in the visual field of the sensor, said likely doublets and their stars constituting a set D; pairing stars of D with detected stars, and supplying all or part of the paired couples of stars to the processing system. Said method is characterised in that it comprises at least the consolidating classification of the set D stars and at least a step using this classification for reducing the number of stars to be paired and/or for carrying out the pairing, and/or for selecting the paired couples. The invention is applicable in particular for determining the attitude of an aircraft or submarine.

Inventor: RAZ RYAN S
IPC: G01N30/74
Filed: 2000-02-08
Abstract: A method and apparatus for sorting and separating particles from a fluid suspension using gas bubbles. The fluid suspension containing the particles of interest is passed through a channel and interrogated to determine the presence of a particle. If a particle is detected, the fluid is subjected to energy to cause the formation of the bubble downstream of the interrogation point. The formation of the bubble is synchronized with the arrival of the particle and the particle is displaced by the bubble into another channel for collection or further processing.      The energy for forming the bubble is supplied by an external laser. The device lends itself to manufacture as a disposable unit and is suitable for sorting and separating cells from a biological specimen.

Title: Method and apparatus for measuring phase differences between intensity-modulated optical signals
Inventor: BABIN FRANCOIS
IPC: H04B10/07
Filed: 2000-03-31
Abstract: In order to avoid errors inherent in the measurement of electrical phase or pulse arrival time in relative group delay measurements, different optical signals have their intensity modulated at a common high frequency, different permutations are selected, their amplitudes detected, and phase differences between the signals are computed on the basis of trigonometrical relationships between amplitude and phase. In one embodiment, two optical signals are provided with continuous wave modulation at the same high frequency, transmitted along different optical paths, and detected individually and in combination. Following conversion to corresponding electrical signals, the amplitudes corresponding to the individual signals and combined signals, are measured and used to compute phase differences between the two optical signals. The computation relies upon trigonometrical relationships to extract the phase differences. Because the frequency of the modulation is known, the time differences can be deduced. Conveniently, apparatus for measuring the phase differences comprises a slotted wheel or other selection device which passes different selections of the optical signals, the first signal alone, the second signal alone, and both together. One of the optical signals may be split to produce a third signal, and a known propagation delay, preferably corresponding to about 90 degrees at the modulation frequency, introduced into the path taken by the third optical signal. The amplitudes of seven possible permutations of the three optical signals then are used to compute the phase difference. The phase difference measurements may be made for a plurality of different physical variables of one or more of the optical signals or the paths taken thereby, and used to compute, for example, chromatic dispersion, polarization mode dispersion, elongation, and so on.
