An apparatus for analysing a fluorescent sample disposed on a substrate comprises a first processor for producing first and second electrical signals derived from respective first and second light signal components received from a sample and from a substrate. The apparatus produces the first and second electrical signals such that there is a phase difference between phases of the first and second electrical signals. The apparatus comprises a control circuit for producing an attenuation signal for attenuating the second electrical signal.

Apparatus and method for analyzing a fluorescent sample disposed on a substrate

A method for measuring a fluorescent sample on a substrate. The method includes exciting the fluorescent sample with an exciting light source for the generation of a sample fluorescent optical signal and a substrate fluorescent optical signal substantially eliminated. The microfluidic substrate fluorescent optical signal is leaving the sample fluorescent optical signal. The sample fluorescence optical signal can then be processed.

An apparatus for continuous cardiac output monitoring ascertains cardiac output by measuring the cross-sectional area of the vessel and the flow rate of fluid flowing through the vessel. The cross-sectional area is derived from the measured resistance within the vessel whereby a pair of signal electrodes injects a known electrical signal into the vessel and the resistance is derived from the known signal and the differential voltage between first and second measuring pairs of electrodes. Resistivity of the fluid is a component of the cross-sectional area derivation, and a temperature sensor is provided to allow for compensating for variations in resistivity with temperature. A velocity sensor is preferably of an optic fiber, Doppler shift type, and the accuracy of the velocity measurement is improved by focusing light emissions from the optic fiber(s) by either providing a Fresnel plate on the terminal end of the fiber or by forming the terminal end of the fiber in a generally conical shape.
