Patent CA-2243677-C (CA)
Inventor: NICELY VINCENT ALVIN
IPC: G01N21/27
Filed: 1997-01-24
Granted: 2001-11-27
Abstract: In a process for analyzing a sample of unknown constitution by an analytical apparatus, a set of analytical measurements and a set of reference measurements, each comprising a set of multivariate signal responses obtained from a set of samples by a first and a second analytical apparatus, are adjusted to remove operational variabilities associated with the apparatus, thereby providing a first and a second matrix of adjusted signal responses.  One of the two matrices of adjusted signal responses is decomposed into a matrix product of a matrix comprising a set of principal factors and a matrix comprising the amounts associated with each of the principal factors. A  compressed signal response matrix product is constructed that comprises a matrix comprising a subset of the set of principal factors and a matrix comprising the amounts associated with each of the principal factors included in the subset. From the latter matrix a projection matrix is computed. Using this projection matrix and a first normalized matrix product that comprises a normalization matrix and the other of the two matrices of adjusted signal responses, a compressed normalized matrix product is constructed. Values of the normalization matrix that minimize the difference between the first normalized matrix product and the compressed normalized matrix product are computed, thereby producing an optimal normalization matrix. A second normalized matrix product comprising the optimal normalization matrix and the one matrix of adjusted signal responses that had been decomposed into a matrix product is constructed. Using the other matrix of adjusted signal responses and the second normalized matrix product, a calibration useful for analyzing the signal responses obtained from the sample of unknown constitution by the first analytical apparatus is constructed and applied to the signal responses from the sample to determine its constitution.

Abstract: In a time division multiple access (TDMA) radiotelephone communications system, a spread spectrum random access channel signal representing a random access message is communicated from a radiotelephone to a central station according to a spreading sequence. In response, a TDMA radiotelephone communications channel is assigned to the radiotelephone. A time division multiplexed radiotelephone communications signal is communicated between the radiotelephone and the central station on the assigned TDMA radiotelephone communications channel over a time division multiplexed carrier frequency band. Preferably, in communicating the spread spectrum random access channel signal, a random access channel signal, representing the random access channel message, is direct sequence modulated according to the spreading sequence to produce a direct sequence modulated random access channel signal. According to a two-stage detection aspect, a synchronization sequence may be associated with a plurality of spreading sequences. The synchronization sequence may be first detected from the communicated spread spectrum random access channel signal, and in response to detection of the synchronization sequence, one of the plurality of spreading sequences associated with the detected synchronization sequence may be detected. A station identification may be assigned to the radiotelephone, with the station identification preferably represented by a digital station identification word. The synchronization sequence and the spreading sequence may be identified from the station identification word, thus associating the synchronization and spreading sequences. The spreading sequence may also be randomly generated from the station identification word.

IPC: C12Q1/18
Filed: 2000-03-02
Granted: 2005-02-22
Abstract: This invention presents rapid methods for evaluating the effects of antimicrobial compounds on microorganisms based upon the microorganism's ability to transport electrons to an external chemical oxidant (a mediator) that is added to the microorganism sample. The mediator interacts with the terminal components of the respiratory pathway and the extent of its consumption is related to the ability of the microorganism to respire. However, under the assay conditions described herein the extent of mediator consumption is different from the microorganisms ability to consume oxygen, due to the addition of metabolizable compounds to the assay mixtures.  The consumed mediator is subsequently measured electrochemically (amperometrically or coulometrically) at the working electrode of a standard two-electrode or three-electrode electrochemical cell. The electrochemical signals (change of current or charge with time) obtained with microorganism suspensions incubated in the absence and presence of antimicrobial compounds are significantly different. These signal differences can be used to screen for antimicrobial effectiveness of antibiotic drugs against clinically important multi-drug-resistant organisms, to screen for the presence of unlawful levels of antibiotic compounds in foodstuffs, or to screen potential new antimicrobial compounds for effectiveness against different species of microorganisms.

Said inner housing shell is arranged at a set distance from an outer housing shell by means of elastic elements and is hereby protected against shocks. The inner housing shell can be brought into precise mechanical contact with the outer housing shell for a short time by means of an electromechanical device. The spatial orientation of the inner and outer housing shells corresponds very precisely. According to another embodiment of the invention, the electromechanical device can be used in the opposite way to deactivate existing shock protection and enable a sensor element to be brought into direct contact with an object being examined for a short time during a measuring operation.</SDO AB>

Abstract: This is an implant for placement in the human body and an assembly for so placing that implant. Most desirably, it is an implant for use in the vasculature of the human body and is used to occlude some space in that vasculature as a portion of a treatment regimen.  The implant itself is preferably a component of a deployment device using an electrolytically severable joint. The implant is electrically isolated from the electrolytically severably joint by a highly resistive or insulative layer. Such isolation and minimization of the conductive pathway from the placement apparatus to the body's fluids appears to enhance the susceptibility of the electrolytic joint to quick erosion and detachment of the implant from the deployment media. Although the implant itself is preferably a vaso-occlusive device, it may instead be a stent, a vena cava filter, or other implant which may be installed in this manner.
