Patent CA-2599945-A1 (CA)
Title: Catheter introducer with needle shield
Inventor: ERSKINE TIMOTHY J
IPC: A61M5/00
Filed: 2006-03-06
Abstract: A needle assembly with a needle shield is disclosed. The shield includes a lumen slidable on the needle, a holder and a needle blocking object which moves at least partially into the lumen in order to block distal movement of the needle. A spring biases the blocking object towards the needle axis.  Proximal movement of the needle relative to the shield is limited by a restraint in the form of a discontinuity on the needle which abuts the shield, a tether or a tube abutting the needle hub. When the needle shield moves from a non-shielding position to a shielding position, the needle blocking object moves at least partially into the lumen. The needle blocking object is radially and axially constrained in the shielding position. The holder also prevents radial, longitudinal and circumferential movement of the blocking object. In one embodiment, the needle blocking object is a ball. A catheter adapter and tube may be threaded over the needle. The needle blocking object may also lock the catheter adapter to the needle shield, allowing it to be released only when the needle is shielded.

Patent CA-2607649-A1 (CA)
Inventor: DURIE ANTHONY ROBERT
IPC: G06F21/55
Filed: 2007-10-24
Abstract: Methods and apparatus for dynamically revising host-intrusion-protection configurations according to varying host state and changing intrusion patterns are disclosed. A set of local servers, each functioning as a deep-security manager supporting a respective subset of the hosts, maintains and updates protection software containing filters and rules for deploying each filter. A local server cyclically monitors each host of its subset of hosts at time instants separated by adjustable monitoring periods to acquire host-characterizing data and determine an optimal set of filters. The local server maintains a profile for each host and determines a current monitoring period for a host according to the host's current profile. The processing effort is reduced by judicial adjustment of successive monitoring periods and selectively tailoring the host-characterizing data to the conditions of each host.

Title: A two-step method to align three dimensional lc-ms chromatographic surfaces
Inventor: SADYGOV ROVSHAN GOUMBATOGLU
IPC: G01N30/86
Filed: 2007-02-07
Abstract: A two-step alignment method for temporally aligning LC-MS data files representative of three-dimensional chromatographic surfaces is disclosed. The method includes apre- alignment step whereby the data files are roughly aligned using a transformation-based correlation analysis of base peak information. The pre-aligned files are used as input to a full alignment step, in which a correlation matrix is computed from the full MS scan information, and an optimal path is traced through the resultant correlation matrix to identify corresponding scan numbers. The use of the pre-alignment step substantially reduces the computational expense of the full alignment step and improves the accuracy and reliability of the alignment.

Title: A method for reshaping, regeneration and retiming of optical data signals and semiconductor for use therein
Inventor: STEFANOV BORIS
IPC: H04B10/299
Filed: 2001-10-05
Abstract: A method and system for AO3R functionality is presented. The system includes an AO2R device followed by an AOCR clock recovery module and an AOR  retiming device. The AOR retiming device takes as input a recovered clock signal extracted from the output of the AO2R by the AOCR clock recovery module. The output is the recovered clock signal gated by the regenerated and reshaped input signal, and a monitor circuit is used to set the optimum operations of the retiming device. In a first embodiment the output of the AOR retiming device is fed to an AOC code and wavelength conversion output stage, which returns the signal to the NRZ coding, on a service wavelength converted to match the fixed wavelength connection with the DWDM transmission system. In a second embodiment the code conversion is incorporated into the AOR retiming device, and wavelength conversion is accomplished in the AOCR clock recovery device.     Previous schemes for performing the 03R functionality use some level of Optical-to-electronic (OEO) conversion to generate the clock signal. The AO3R  scheme presented here carries out all three functions in the optical domain, and returns a clean output signal using identical coding as the input, on a wavelength of choice.
