A method and apparatus for generating an impedance spectrum which is characteristic of a sample of bodily matter in a resonant circuit and which may be used to analyse the sample.

Impedance measurements of bodily matter

There is disclosed a method for analysis and therapy of the eye utilizing laser-induced ultrasound.

Ophthalmic uses of lasers

A method for detecting the occurrence of a condition in a respiring subject includes the steps of: introducing emitted subject respiratory gases to a gas sensing device; detecting certain species present in the emitted subject respiratory gases with the gas sensing device; and correlating the presence of the species with the occurrence of the condition.

Detection of conditions by analysis of gases or vapours

A method for identifying a change in the composition of a liquid, comprising the steps of applying a time varying electrical or electromagnetic input signal to the liquid in a range of frequencies encompassing a resonant frequency of an electrical circuit comprising the liquid; measuring an impedance quantity of the electrical circuit comprising the liquid by means of the output signal as a function of the frequency of the time varying electrical or resonant frequency input signal in said range of frequencies; determining a resonant frequency of the electrical circuit comprising the liquid; after a change in the composition of the liquid, measuring variation in the impedance quantity at or near to the previously determined resonant frequency of the electrical circuit comprising the liquid; and relating the variation in the impedance quantity at or near to the resonant frequency of the electrical circuit comprising the liquid to a change in the composition of the liquid.

Identifying changes in composition of liquids

There is disclosed a gas sampling apparatus ( ) adapted for use in a hand-held gas sensing device ( ) having at least one gas sensor ( ), the apparatus comprising: a gas inlet ( ); a gas conductor ( ) for conducting gas from the gas inlet to the sensor or sensors; a gas outlet ( ), a gas conductor ( ) for conducting gas from the sensor or sensors to the gas outlet; and a vacuum containment ( ) enclosing an inner region having a pressure below atmospheric pressure and adapted for connection to the gas outlet so that a flow of gas is developed from the gas inlet to the vacuum containment.

Apparatus and methods for gas sampling

A microorganism analyzer has a flow-through arrangement into which a microorganism-containing sample may be introduced, and a headspace connected or connectible to a gas analyzer. The headspace is connected to the flow-through arrangement so as to be affected by the sample.

Microorganism analysis means

There is disclosed a method for interrogating a sensor comprising the steps: applying a periodic electrical signal to the sensor; obtaining a signal therefrom; and performing an operation on the obtained signal to obtain the sensor response at a plurality of frequencies, said operation including a transformation to the frequency domain of said signal or a quantity related to said signal.
