Patent CA-2192648-A1 (CA)
Inventor: WONG PATRICK T T
IPC: G01N1/30
Filed: 1995-06-23
Abstract: The presence of anomalies in biological tissue and cells in natural or cultured form (e.g. cancerous tissue or cells) is detected by directing a beam of infrared light at a preservative treated sample, prepared from fresh biological tissue or cells, in either the transmission mode or the Attenuated Total Reflectance (ATR) mode. The anomaly is then determined by whether changes in infrared absorption have occurred, due to the vibration of at least one functional group of molecules present in the sample, which are characteristic of the anomaly. The preservative may be an aqueous solution of formalin, an aqueous solution of ethyl alcohol, or an aqueous solution of inorganic salts. The preservative treatment prevents degradation of the sample at room temperature which has been found to change the infrared absorption characteristics which can lead to misinterpretations.

Title: Rate measurements of biomolecular reactions using electrochemiluminescence
Inventor: LELAND JONATHAN K
IPC: G01N33/532
Filed: 1995-12-04
Abstract: A biomolecular reaction, such as an enzymatic or affinity binding reaction is effected in an electrochemical cell with a mixture of reagents including a luminophore which will relate the concentration of a reactant, a reaction partner or the reaction product of a reaction partner to the electrochemiluminescent intensity, in order to determine the rate of the biomolecular reaction. The reaction partner is a reagent which reacts with the reactant and which itself or its reaction product participates with the luminophore to cause ECL emmissions. The ECL intensity is modulated with a series of electrical pulses which are applied to the mixture of reagents at a preselected potential for preselected intervals of time and duration. The intensity is measured during those intervals to provide a timed series of values (P). The same experiment is repeated twice more, once wherein the modulation is conducted after the reaction has gone to completion to obtain the timed series of values (C), and the last time the reaction is performed in the absence of the reaction partner to obtain the timed series of values (B). The results are normalized (N) using the formula I to obtain a series of values (N) which are plotted to obtain the time course of reaction.

IPC: G01R19/25
Filed: 1997-08-29
Abstract: In accordance with the present invention, an rms (root mean square) converter using digital samples is provided. The rms converter is implemented using a squaring circuit followed by an rms digital filter and a square root circuit. Each digital sample from the ADC is squared and then presented to an rms digital filter which produces filtered digital samples. A square root circuit then calculates the rms values from the filtered digital samples. The rms digital filter has a transfer function that is essentially a low pass filter that extracts the rms value from the stream of digital samples in a continuous manner without regard to the period or waveshape of the signal.
