A sanitary method and system of providing touch interface experiences to users of public devices are disclosed. In one aspect, the system and method are configured to deploy a clean, protective barrier across a touchscreen for each user of the public device. The barrier includes a transparent membrane that permits the user to provide touch-based inputs to the touchscreen through the barrier. In cases where the touch interface is generated by a projector, the system and method are configured to deploy a membrane that serves as a disposable screen for the projected interface. Once each user completes their session, the system automatically replaces the used membrane with a fresh membrane, ensuring subsequent users are not exposed to contaminants or residue from previous user sessions.

The present disclosure generally relates to a system for treating a surface, comprising an ultraviolet (UV) lighting arrangement configured to emit UV light towards the surface at a first and a second wavelength range to effectively reduce microorganisms at the surface.

A system for controlling a power signal for zero voltage switching (ZVS) includes a voltage zero crossing detection module to detect a zero voltage condition in response to an inverter voltage from a resonant inverter crossing zero volts, and a current zero crossing detection module to detect a zero current condition in response to an inverter current from the resonant inverter crossing zero amps. The system further includes a phase detect module to detect actual phase data corresponding to an actual phase angle between the inverter voltage and the inverter current based on the zero voltage and zero current condition. The system further includes a comparator to determine a phase difference between a desired phase between the inverter voltage and the inverter current and the actual phase angle. The system further includes a controller to adjust a property of a resonant inverter to reduce the phase difference.

A system for monitoring an excimer bulb includes a thermoelectric energy harvester configured to be located adjacent to the excimer bulb and to convert thermal energy from the excimer bulb into electrical energy having a voltage. The system further includes a controller in electrical communication with the thermoelectric energy harvester and configured to calculate at least one of a remaining useful life of the excimer bulb or a current temperature of the excimer bulb based on the voltage of the electrical energy converted by the thermoelectric energy harvester.

A storage compartment for a vehicle includes a body defining a sterilization volume configured to receive an item to be sterilized. The body includes a lower wall, and a side wall extending from the lower wall. A lid is coupled with the at least one of the walls and is configured to selectively close the sterilization volume. A lighting assembly is provided, to direct emitted light into the sterilization volume.

A flushometer including a sanitation unit is described herein. The sanitation unit may be configured to emit ultraviolet light in response to the flushometer effectuating a flush of the fixture. The ultraviolet light may sterilize and/or sanitize a plume caused as a result of the flush. The ultraviolet light may be emitted for a predetermined amount of time to sterilize, sanitize, and/or kill any pathogens contained in the plume. Additionally or alternatively, the sanitation unit may emit the ultraviolet light periodically. For example, the sanitation unit may emit the ultraviolet light in response to receiving one or more signals from a gateway and/or server. The sanitation unit may provide an environmentally friendly solution that reduces water consumption and/or cleans, sanitizes, and/or sterilizes plumbing fixtures, toilet seats, etc. between uses without the need for harsh chemicals and/or cleaning solutions.

Disclosed embodiments can pertain to process indicator enhancements. A process indicator can include a dye material that has electrical properties such as conductivity and capacitance that can be employed to determine whether observed conditions are acceptable or not to sterilize medical equipment. Furthermore, the indicators can employ amplification, a specialized antenna, or both to allow signals, such as an electronic property value, to be communicated through sterilization containers that can shield or degrade signals. A number and location of indicators can also be determined and utilized to assist in visual inspection of the indicators as well as automatic evaluation.

A hand-held operation cleaning, sterilization and disinfection atomizing diffuser, provided that the user conveniently holds a handle of the diffuser to operate a control unit to provide power to an air extraction device and a pumping control device to pump the cleaning, sterilizing, disinfecting or/and deodorizing liquid out of a liquid storage tank to expel via a water jet, and the gas extracted from the air extraction forms a jet stream through an air jet, and the liquid sprayed by the water jet is broken by the jet stream of the air jet at a high speed into fine droplets and atomized to clean, sterilize, disinfect or deodorize towards a target.

A sterilization system for sterilizing an article is disclosed. The sterilization system may include a hydrogen peroxide generation system configured to generate hydrogen peroxide, a hydroxyl generation system configured to produce a flow of hydroxyl radicals that causes deterioration of the hydrogen peroxide to produce hydroxyl ions, and a sterilization chamber configured to expose the article to the hydroxyl ions to sterilize the article. Additionally, methods for sterilizing articles are disclosed. Those methods may include generating hydrogen peroxide, producing a flow of hydroxyl radicals that causes deterioration of the hydrogen peroxide to produce hydroxyl ions, and exposing the article to the hydroxyl ions to sterilize the article.

Systems are disclosed which include processor-executable program instructions for receiving data regarding characteristics of an area or a room and determining, based on the received data, operating parameter/s for one or more disinfection sources to disinfect the area/room. The data may include data regarding non-physical characteristics and/or physical characteristics of the area/room. In some embodiments, data regarding a quantity and/or type of at least a subset of the plurality of disinfection sources for disinfecting the room may also be considered for determining the operating parameter/s. In addition or alternatively, the data may be in relation to multiple disinfection sources in the area/room. In any case, a system is also disclosed which facilities power redirection among multiple disinfection sources upon detecting a given area has received a predetermined dose of ultraviolet light.
