    摘要： An infrared spectrometer for the determination of isotopic ratios of gaseous compounds includes a broad-band infrared light source, a spectral selector, a sample compartment, an infrared detector, and a processor. The spectral selector selectively transmits a wavelength window of infrared light covering a range of wavelengths in which the wavelength window can be selected alternatively to overlap with a wavelength range primarily absorbed by a compound with a first isotope or by the compound with a second isotope. The sample compartment holds a gas sample and includes a gas inlet and a gas outlet. The infrared spectrometer can be used to detect isotopic ratios of carbon dioxide, where enhancement of 13CO2 can indicate metabolic activity of an infection, for example by H. pylori, or of specific enzymes. Preferred embodiments use a particular multipass optical cell that includes a field mirror and a multi-segment objective mirror.

    摘要： An acoustic sensor detects presence and/or absence of fluid in a fluid delivery medium. The acoustic sensor detects fluid absence based on the difference of the speed of sound between air and a fluid. For example, the acoustic sensor may detect fluid absence based on a phase shift between acoustic signals transmitted through the fluid delivery medium when fluid is present as compared to acoustic signals transmitted through the fluid delivery medium when fluid is absent, e.g., when air or bubbles are present in the fluid delivery medium.

    摘要： A portable multi-channel device for optically testing of a liquid sample includes a controller; and a sample holder with a cylindrical sample compartment and at least two optical channels respectively for measuring turbidity of the sample liquid and for measuring one other optical property of the sample liquid. Each of the optical channels including: a light source placed at one end of the channel, a main detector placed across the sample compartment from the light source, a reference detector for measuring an intensity of light emitted by the light source, and an excitation focusing optic for directing a light emitted by the light source through the sample compartment towards the main detector. Signals from the reference detector of the channel, the main detector of the channel, and another main detector of another channel perpendicular to the channel are processed by the controller to evaluate the turbidity of the liquid sample.

    摘要： A sensor array includes a plurality of sensors connected to two or more groups of wires such that individual sensors can be addressed. No two sensors are connected to the same two wires. The groups of wires are connected to multiplexers or the like to address particular wires connecting a unique sensor. Dramatically improved accuracy is obtained by connecting rectifiers in series with the sensors to significantly reduce reverse current through a sensor that can lead to significant errors. In some preferred embodiments, the array includes a plurality of temperature sensors, especially for use in measuring temperature at different depths in a body of water

    摘要： A system and associated processes monitor hand hygiene compliance. The system includes hand hygiene product dispensers positioned within areas of concern (AOC) in a facility in which hand hygiene events are to be monitored. The dispensers detect dispense events initiated at the dispenser and transmit a dispense event signal indicative that a dispense event occurred along with dispenser identification information. The system also includes a plurality of compliance badges, each worn by a different person in the facility. Each compliance badge receives dispense event signals corresponding dispenser identification information associated with dispense events initiated by the wearer of the compliance badge. The badges store dispense event records associated with each dispense event initiated by the wearer and thus keep track of all dispense events initiated by the wearer of the compliance badge. One or more data gathering stations positioned at various locations through the facility receive the dispense event information from the individual badges when they come within range. The dispense event information may then be transferred to a local or remote computer for analysis and reporting on hand hygiene events taking place within the facility.
