Patent CA-2427164-A1 (CA)
Inventor: HYDE DAVID D
IPC: G01N35/02
Filed: 2003-04-29
Abstract: A method for dynamically determining the volume of a liquid dispensed by a metering system, the metering system including a metering pump, a pump motor, a sensor, and a conduit interconnecting the pump and a metering probe. The method includes the steps of aspirating a quantity of fluid into the metering probe using the metering pump, moving the probe relative to a reaction vessel, and dispensing the fluid. The dispensing step includes the steps of identifying an onset point associated with a parameter which can be measured by the metering system, identifying an end point associated with the measurable parameter, and timing the pump motor during the period between the onset point and the end point in order to determine fluid volume. The sensor, such as a pressure transducer or capacitance change sensor, disposed in relation to the conduit can detect changes in the parameter and identify the onset and end points.

Abstract: A method and apparatus controlling a mold melt flow using inner (impinge) and/or edge temperature sensors (316, 310, 312, 314). Thermal waveforms from thermal sensor array data such that if a sequence of melt temperature set- point trigger times fluctuates outside control limits, then the melt-flow is judged as a hotter/faster or cooler/slower melt-flow injection process. An initial melt temperature set-point "trigger" and second reference set-point "trigger" are combined to control the closure of at least one cavity gate in accordance with an injection melt-flow time and temperature profile. The nozzle orifice (310) area sets an initial melt-flow rate. Each mold cavity (318) final melt-flow "pack" volume is preferably contolled by a gate cavity melt shut-off system that is responsive to the sensed temperature(s), resulting in each cavity melt-flow injection process volume being held substantially constant, for a uniform resin "shrink" density.

Abstract: A technique for providing an announcement in a communications network includes setting up a first level communication session in a first network element of the network. A determination is then made that an announcement is to be played to the first network element. An identity of a second network element which is to play the announcement on the first communication session is then sent and after a second level communication session is set up, the second level communication channel parameters are modified in accordance with the transmitted identity. The second network element then plays the announcement to the first network element. The transmitted identity may include an IP  address or a port number or a TA. The communication session may include a PDP  context. The first network element may include a Mobile Station.

Title: Tissue-specific endothelial membrane proteins
Inventor: STEVENS ANTHONY C
IPC: A61K48/00
Filed: 2002-06-07
Abstract: Methods and compositions for targeting of pharmaceuticals or other therapeutics to specific tissues using tissue-specific endothelial membrane proteins are provided. The compositions comprise a therapeutic complex composed of a ligand, a linker, and a therapeutic moiety, where the therapeutic moiety can enter the cell. The ligand can be an antibody or other molecule that binds to a tissue-specific protein on the endothelial membrane of a specific tissue. The ligand need not activate a receptor, but may activate endocytosis. The therapeutic moiety can be a drug, gene, antisense oligonucleotide, contrast agent, protein, toxin, or any type of molecule that acts on the specific tissue. The linker can be a liposome or a cleavable or noncleavable chemical molecule. Alternatively, the linker may simply be the bond between the ligand and the therapeutic moiety. Alternatively, a lipophilic prodrug may be cleaved and may enter the cell due to its lipophilic properties.

Title: Estimating storage requirements for a multi-dimensional clustering data configuration
Inventor: SWAGERMAN RICHARD E
IPC: G06F17/30
Filed: 2003-12-17
Abstract: A method for estimating storage requirements for a multi-dimensional clustering data configuration. The storage required for the proposed multidimensional clustering data is estimated by modeling wasted space. The amount of wasted space may be modeled by calculating the cardinality of the unique value of the clustering key for the proposed configuration. Cardinality may be determined by estimation techniques. Specific values for wasted space and total space may be determined in response to the determined cardinality. Comparison of estimates for different proposed clustering configurations may facilitate a selection among the proposals.

Title: Chromatic dispersin compensation
Inventor: VAN SCHYNDEL ANDRE
IPC: H04B10/2507
Filed: 2002-12-05
Abstract: A method and apparatus for compensating, in the electrical domain, for chromatic dispersion of an optical signal is disclosed. An optical signal is converted to an electrical signal comprised of components which are recoverable and components which are not directly recoverable. A first approximation of the output is derived by applying a transfer function to the electrical signal. The components of the electrical signal which are not directly recoverable are then estimated by applying a second transfer function to the first approximation. After removing these components a second approximation of the output is obtained by re-applying the first transfer function to the result. The optical signal may have a suitably small extinction ratio to improve compensation. The square root of the electrical signal may be taken to improve compensation. A better approximation may be achieved by re-applying the above method iteratively.
