Abstract: 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. 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.

Abstract: An optical sensor may have multiple detection channels to detect different characteristics of a fluid. For example, an optical sensor used in industrial cleaning and sanitizing applications may have multiple detection channels to detect when a system is both clean and properly sanitized. In one example, an optical sensor includes an optical emitter that directs light into a fluid, a first optical detector that detects light transmitted through the fluid, a second optical detector that detects light scattered by the fluid, and a third optical detector that detects fluorescent emissions emitted by the fluid. The optical emitter and optical detectors can be positioned around an optical analysis area. The optical sensor may include filters that control the characteristics of light detected by each of the optical detectors.

Abstract: Systems and methods for determining a flow rate or volume of fluid. The system includes a positive displacement meter including a plurality of non-contact sensors and gears configured to rotate in response to fluid flow through the meter. The gears may include detectable areas that may be sensed by the plurality of non-contact sensors to determine a rotational direction of the gears. The plurality of non-contact sensors may also be configured to generate respective detection signals indicative of a rotation state of the gears. The controller may be configured to receive the detection signals, determine a current rotation state, and increment a rotational count based on the changes in the current rotation state. The controller may use the rotational count to determine a flow rate or volume of fluid.
