    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 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.

    摘要： An H-bridge control circuit comprises an input stage, comparator stage, inverter stage. The operation of the H-bridge can be controlled by a single analog input signal provided by a feedback stage. Shoot-through protection is provided for the H-bridge circuit through the inclusion of a dead gap determined by inputs to the comparator stage. The dead gap can be adjusted, allowing for adjustment of the precision operation of the load. The H-bridge can be used to drive a bi-directional load such as, for example, a Peltier conditioner.

    摘要： An optical detection sensor detects presence or absence of a product within a fluid delivery medium. An emitter directs radiation into the fluid delivery medium. Each of a plurality of detectors detects light within an associated one of a plurality of wavelength ranges transmitted through the fluid delivery medium. The output of each detector is further associated with at least one out-of-product threshold. A controller may further combine detector outputs, such as by multiplication, summation, or other mathematical operation, to produce additional measures of product presence or absence. Each combination output is also associated with at least one out-of-product threshold. The controller compares the output of each detector with the associated out-of-product threshold(s) and compares each combination output with the associated out-of-product threshold(s) to determine presence or absence of product within the fluid delivery medium. The sensor is able to determine presence or absence of a variety of products having different color, transparency or turbidity.
