Patent CA-2327789-A1 (CA)
Title: Membrane with tissue-guiding surface corrugations
Inventor: LEMPERLE STEFAN M
IPC: A61B17/08
Filed: 1999-04-07
Abstract: A resorbing, flexible implant in the form of a continuous macro-porous sheet (42) is disclosed. The implant is adapted to protect biological tissue defects, especially bone defects in the mammalian skeletal system, from the interposition of adjacent soft tissues during in vitro repair. The membrane (42) has pores with diameters from 20 microns to 3000 microns. This porosity is such that vasculature, and connective tissue cells derived from the adjacent soft tissues including the periosteum, can proliferate through the membrane into the bone defect. The thickness of the sheet is such that the sheet has both sufficient flexibility to allow the sheet to be shaped to conform to the configuration of a skeletal region to be repaired, and sufficient tensile strength to allow the sheet to be so shaped whitout damage to the sheet. The sheet provides enough inherent mechanical strength to withstand pressure from adjacent musculature, and does not collapse.

Patent CA-2330676-A1 (CA)
Inventor: MOSES ROBERT W
IPC: H04N7/24
Filed: 1999-05-11
Abstract: A method and apparatus is described for recovering data sample clock rates from received isochronous streams of data packets including associated time stamp values, such as in an IEEE 1394 bus-interconnected system. The difference between consecutive time stamp values is determined by successively latching the time stamp values and applying them to a subtracter circuit to produce a difference value. This difference value is then successively decremented by a down counter, with the down counter then producing a signal pulse and loading a next difference value upon completion of the count. The pulsed signal is applied to a phase-locked loop to provide a frequency multiple, and a clock signal is correspondingly produced that has a frequency proportional to the difference between the consecutive time stamp values. Data input buffer levels may be monitored and the clock signal frequency adjusted accordingly.

Title: System consisting of an oil pump and of a valve for oil burners
Inventor: LUESCHER MICHEL
IPC: F23D11/00
Filed: 2000-01-27
Abstract: The invention relates to a system made of an oil pump and of a magnet valve for preventing oil from dripping when the oil burner is switched off. The inventive system is provided with an oil pump (23) and a magnet valve (10) which has a closing body (16) that comprises an oil flow borehole (17). The closing body (16) is displaceably located in a borehole (12). An oil line (11) goes through the borehole (12). The oil flow borehole (17) of the closing body (16) complements the oil line (11) in a first position of the inventive magnet valve (10). The oil flow is thus released. The closing body (16) interrupts the oil line (11) in a second position of the magnet valve (10). A vacuum is simultaneously generated in said second position. The vacuum reverses the direction of oil flow in an end section (15) of the valve (11). The oil is thus prevented from dripping.

Title: Training and synchronization sequences for wireless systems with multiple transmit and receive antennas used in cdma or tdma systems
Inventor: RUPP MARKUS
IPC: H04J13/10
Filed: 2001-07-03
Abstract: Orthogonal sequences can be developed and used for use training and synchronizing in CDMA and TDMA systems. In particular, once a sequence is developed that has the length of the product of the channel length and the number of transmit antennas, the sequence is offset by a different amount for each transmit antenna. For example, each sequence could be offset by a multiple of the channel length for each transmit antenna, where the multiple ranges from 0 to N-1, where N is the number of transmit antennas. Furthermore, by not using exactly the same amount of offset shifting for each transmit antenna, e.g., not having each signal offset by the channel length, but keeping the overall total shifting the same, e.g., the average of each shift is the channel length, it is possible to determine at a receiver from which transmit antenna a particular signal originated.

Title: Helium droplet mass spectrometery (hdms)
Inventor: BEMISH RAYMOND JOHN
IPC: G01N30/72
Filed: 2001-10-09
Abstract: A method and device for mass spectrometry analysis, wherein a mass spectrometer is adapted for use with helium droplets, as an ionization site medium, with a proton being initially captured by a large helium droplet (-10,000 helium atoms) and then cooled evaporatively to 0.4 Kelvin. The protonated helium droplet then picks up a neutral molecule of interest and the neutral molecule is protonated inside of the droplet with the liquid helium droplet acting as a heat bath to provide rapid cooling of the newly formed protonated molecule. As a result, there is essentially no energy available, at 0.4 Kelvin, for the protonated molecule to fragment. Remaining liquid helium is removed and the stably maintained protonated molecule is detected by a mass spectrometer. Since the molecules do not fragment when protonated (ionized), each compound in a mixture analyses gives one mass and the number of ions of a particular mass detected is directly proportional to the molar percentage of that mass in the sample. The device for effecting the method, comprises the elements of : (1) Helium cluster or droplet source; (2) Proton source for introduction of protons to the droplet (i.e., ionization); (3) atmospheric pressure (AP) Source for reduction of pressure to form a low pressure stream; (4) Cell pick-up elements where compound molecules are protonated or ionized at low temperature; (5) Desolvation area for removal of residual helium; and (6) Mass spectrometer and detector.
