Abstract: Embodiments of the present inventive concept include retrofit compliance apparatus, which can include a catch basin or drip tray. The retrofit compliance apparatus can be used in conjunction with a hand hygiene dispenser, and monitor for compliant usage of the dispenser. The retrofit compliance apparatus can include one or more microcontrollers and one or more sensors. The retrofit compliance apparatus can detect whether the dispenser has been properly used. The retrofit compliance apparatus can collect data allowing the determination of the identity of who used the dispenser. Historical information about valid dispense counts and invalid dispense counts for each individual user can be maintained by a remote server.

Abstract: The disclosed device, system, and method can be used for monitoring hygienic dispenser usage and compliance. A hygienic dispenser dispenses a hygienic substance such as sanitizer, soap, a glove, or the like. A hygienic sensor adapter device is proximately disposed to the hygienic dispenser. The hygienic sensor adapter device detects a presence of a human hand within an activation area of the dispenser. The hygienic sensor adapter device includes a sensor to detect badges worn by corresponding human subjects. A remote cloud-based computer server can determine a particular human subject from among the human subjects to which the human hand belongs. Accordingly, the hygienic sensor adapter device is able to monitor the activations of all models of hand hygiene dispensers with little to no configuration or modification. The hygienic sensor adapter device rejects false triggers, captures every dispenser activation, and identifies the subject responsible for the dispenser activation.

Abstract: Radio-frequency (RF) excitation is used for direct detection of hybridization events at microelectrodes with surface-attached DNA oligomers. A homodyne reflectometer operates on a high frequency carrier to detect the presence of a low-frequency modulation signal. Without non-linearities in an interface, the modulation signal is not impressed upon the carrier signal. As such, the reflectometer can sensitively measure changes in dielectric properties without interference from other sources of capacitance/resistance unrelated to the reaction at the surface.
