摘要： A sensor for sensing the concentration of a vapor of a volatile liquid in a gas is disclosed. The sensor has a dry-transducer temperature sensor and a wet-transducer temperature sensor. The wet transducer-temperature sensor is covered by a non-woven, non-flaking, liquid-permeable material to allow the liquid to pass from a source to about the wet-transducer temperature sensor and vaporize when the gas is not saturated with the vapor. The vaporization of the volatile liquid causes the temperature at the wet-transducer temperature sensor to have a steady-state temperature lower than the reference temperature measured by the dry-transducer temperature sensor. The difference in the temperature measured by the two temperature sensors being determinable to determine the concentration of the vapor in the gas. In an embodiment, the non-woven, non-flaking, liquid-permeable material is a porous membrane. In another embodiment, it is a gel.

摘要： A noninvasive blood chemistry measurement method and system isolate measurement contributions due to a patient's blood to accurately measure blood chemistry. In accordance with a first preferred embodiment of the present invention a noninvasive blood chemistry measurement method decreases the blood volume within a patient's body part relative to the normal blood volume in the body part and performs a baseline measurement. Blood volume is then increased and a second measurement is performed. Comparison of the second measurement to the baseline measurement isolates the measurement attributes of the patient's blood. In accordance with a second preferred embodiment of the present invention a noninvasive blood chemistry measurement system decreases blood volume by applying mechanical pressure to a body part. In accordance with a third preferred embodiment of the present invention, blood volume in the body part is decreased using a pressure cuff. In a fourth embodiment, a noninvasive probe accurately measures blood chemistry and uses a suction cup to increase blood volume at the blood chemistry measurement site.

摘要： A sensor (10) is provided for detecting the concentration of potassium ions which comprises a molecule which selectively complexes potassium ions. The molecule, e.g., 2,2-bis[3,4-(15-crown-5)-2-nitrophenylcarbamoxymethyl]tetradecanol-14, has at least one binding site and is provided with a fluorophore group, e.g., Rhodamine-B, at that site. The molecule is one that expands upon complexation of potassium ions, such that the intensity of fluorescence increases. The change in fluorescent intensity is a direct measure of the concentration of potassium ions. A detector employing the sensor is also provided.

摘要： A fiber optic pressure sensor suitable for use in measuring, for example, arterial blood pressure, is taught. A catheter tip is formed utilizing the phenomena of collision quenching or Foerster energy transfer quenching of fluorescence in order to measure the pressure exerted by the medium in which the sensors are placed. When utilizing a collision-quenching type of sensor, the change in concentration of a quencher is measured, the quencher being enclosed in the sensor tip, which is in hydrodynamic equilibrium with its ambient environment. Foerster-quenching type sensors measure the change in distance between the quencher and the fluorophore, which in turn are caused by pressure changes caused by the ambient environment in which the sensor is placed.
