Patent CA-2333452-C (CA)
Inventor: MCKOWN RUSSELL

Abstract: The cardiac ejection fraction (EF) is estimated based on the parameters of a model of an indicator (such as thermal) dilution through the heart. A channel model is defined by an upstream indicator injector, such as a heater, positioned preferably in the right atrium/ventricle and a downstream indicator concentration sensor, such as a thermistor. The preferred model is a lagged normal transfer function, which has as one of its output parameters the indicator decay constant .tau. of the blood channel. The heart rate (HR) is also measured. The ejection fraction (EF) is then calculated continuously as EF = 1-exp(-60/(.tau.*HR)).  The cardiac output (CO) is also estimated in the model, preferably based on an estimate of the zero-frequency gain of the lagged normal transfer function. End diastolic volume (EDV) is then also calculated continuously as a function of CO, HR and EF. In applications where the step response of the indicator concentration sensor is slow relative to the indicator decay, the transfer function Hs of the sensor is determined ahead of time. Parameters characterizing Hs are then stored in a memory device and the measured transfer function data is scaled by Hs prior to modelling to provide the most accurate EF estimate.

Title: Longitudinally flexible stent
Inventor: PINCHASIK GREGORY
IPC: A61M29/00
Filed: 2001-02-27
Granted: 2011-01-25
Abstract: An intravascular stent especially suited for implanting in curved arterial portions. The stent retains longitudinal flexibility after expansion. The stent is formed of intertwined meander patterns forming triangular cells. The triangular cells are adapted to provide radial support, and also to provide longitudinal flexibility after expansion. The triangular cells provide increased coverage of a vessel wall. The stent can have different portions adapted to optimize radial support or to optimize longitudinal flexibility. The stent can be adapted to prevent flaring of portions of the stent during insertion.

Abstract: Signals are developed for use in a wireless system with multiple transmit and multiple receive antennas so that even in the face of some correlation the most open-loop capacity that can be achieved using a substantially open-loop system with a channel of that level of correlation is obtained. In accordance with the principles of the invention, the signals transmitted from the various antennas are processed so as to improve their ability to convey the maximum amount of information. More specifically, the data to be transmitted is divided into M+1 substreams, where M is the number of transmit antennas. Each transmit antenna is supplied with a combination signal that is made up of a weighted version of a common one of the substreams and a weighted version of a respective one of the substreams that is supplied uniquely for that antenna, so that there are M transmit signals. A receiver having N antennas receives the M transmit signals as combined by the channel and reconstitutes the original data therefrom. This may be achieved using successive decoding techniques. Advantageously, the capacity, i.e., the . rate of information that can be conveyed with an arbitrarily small probability of error when the instantaneous forward channel condition is unknown to the transmitter, is maximized.

Abstract: A routing algorithm having particular advantage in sparsely connected networks in which nodes have a ranked set of alternative routes to a destination node, these routes being node-disjoint. Setup messages (30) have an additional information element (34) for the identity of a virtual source node, and a source node inserts its own identity in the virtual source information element. Unless a node is the destination for a message, it examines the content of the virtual source information element (34) of a message, and if there is no match with its own identity it selects from its routing table a predetermined alternative route for the destination node. If that route is unavailable, the node replaces the content of the virtual source information element (34) with its own identity, and performs routing on the basis that there is now a match with its own identity, i.e. it behaves as if it had generated the message. It selects from its routing table the highest ranking of the set for the destination node, and in the event of a fault on the highest ranking route, tries one or more lower ranking routes. If no route is available, the node replaces the content of the virtual source information element (34) with the identity of the node from which it was received, and sends the message back to the node from which it was received.

Title: Laser imaged printing plates comprising a multi-layer slip film
Inventor: KANGA RUSTOM SAM
IPC: G03F7/11
Filed: 2000-11-17
Granted: 2009-01-20
Abstract: The present invention provides a method of making a laser imaged printing plate. First, a solid, uncured printing plate is modified with both a UV absorber and an IR absorber. This is most conveniently done by constructing a multilayer slip film (12) comprising at least two layers wherein at least one layer (14) comprises a strong UV absorber, and wherein at least one other layer (16) comprises an IR absorber having high absorptivity. The multilayer slip film (12) is already adapted for use with a printing plate and is applied in the usual fashion to the surface of the uncured printing plate. The printing plate with the multilayer slip film (12) is ablated from the photopolymer (18) using an IR laser operating at a selected wavelength to create an in situ negative. The resulting negative can be subjected to typical UV flood exposure and development.

Granted: 2008-04-29
Abstract: A reaction vessel, particularly for use in parallel synthetic chemistry, is characterized by an inner structure, namely a reaction chamber and a discharge channel which are interconnected. The interconnection preferably consist of a connection channel between the bottom of the reaction chamber and the discharge channel so that almost any liquid in the reaction chamber can be removed through the discharge channel. The connection channel may be molded by an extension hinged to the core molding the reaction chamber, so that the reaction vessel can be conveniently manufactured by injection molding. A reaction block particularly for use with these reaction vessels comprises a closure means covering the open ends of the discharge channel and the reaction chamber of at least two of the reaction vessels. By guiding means the closure means is directed to perform a generally linear movement in moving from the opening to the closing position, and during this movement, to move towards the open ends of the vessels in order to close them with a force withstanding also an overpressure possibly developing within the vessels.
