A sanitizing device particularly suitable for sanitizing personal use items such as a menstrual cup. The sanitizing device includes top and bottom half members, top and bottom reflective members positioned within the top and bottom half members, respectively, and a planar quartz glass member to ensure that all interior and exterior surfaces of the menstrual cup are adequately exposed to UVC light to achieve sanitization.

A disinfecting system and method for an enclosed space include an articulating arm moveably coupled to a structure within the enclosed space. An ultraviolet (UV) lamp is coupled to the articulating arm. The UV lamp is configured to emit UV light toward a disinfection zone within the enclosed space. The articulating arm allows the UV lamp to move relative to the disinfection zone.

The present disclosure provides an ultraviolet (UV) sterilization apparatus that is capable of changing an emission mode and/or an emission angle. The UV sterilization apparatus includes a sterilization unit configured to be movable to a predetermined position and including a UV emitter, and a driving unit configured to move the sterilization unit.

The present disclosure provides an ultraviolet (UV) sterilization apparatus that has improved heat dissipation performance and is capable of being changed in position. The UV sterilization apparatus includes a sterilization unit configured to be movable to a predetermined position and including a UV emitter, a driving unit configured to move the sterilization unit, and a cover having a structure accommodating the sterilization unit and allowing the inside of the cover to communicate with the outside. A heat sink is provided in the cover in order to dissipate heat from the sterilization unit.

An HVAC duct ozone generator includes at least two ozone generation plate stacks, where each plate stack includes at least two independently electrically addressable plate groupings, where a primary plate grouping includes fewer ozone generation plates than a secondary plate grouping. Thus, the generator includes at least four independent ozone generation control channels to energize the primary and secondary plate groupings of each of the at least two plate stacks. The number of plates in a plate grouping may optionally be altered to reduce the ozone generation capacity of the primary plate grouping in relation to the secondary plate grouping through the movement of resistive collars between the stacked ozone generation plates.

An irradiation method includes irradiating an environment with light using one or more one ceiling-mounted light sources, where each ceiling-mounted light source has an optical axis oriented vertically downward, and wherein each ceiling-mounted light source emits a light distribution having more angle-integrated intensity in a higher angular range relative to the optical axis of the ceiling-mounted light source than in a lower angular range relative to the optical axis of the ceiling-mounted light source. A ceiling-mounted light source may include a support structure, one or more light emitters disposed on a surface of the support structure, and a reflector with a funnel-shaped reflective surface facing the support structure and expanding with increasing distance from the support structure along the optical axis. The light emitters may be ultraviolet (UV) light emitters whereby the light source is a UV ceiling-mounted light source.

A sanitation device includes a housing with a channel extending into the housing and a plurality of openings in the channel. A plurality of light emitting diodes emit light through the openings in the channel. A shield is coupled to the housing and a motion sensor emits and detect light through the shield when activated, such that the shield narrows a field of view of the motion sensor. The sanitation device is positioned near a common touch point with the motion sensor determining when an object is near, and has moved away from, the touch point. The plurality of light emitting diodes are activated to clean the touch point after the object moves away. The sanitation device may further include a status indicator light to provide information regarding the current state of operation of the sanitation device.

A method is provided for vaporized hydrogen peroxide cleaning of a chamber. The method includes altering a temperature of air in the chamber from an initial temperature to a sterilization temperature over a first time period. The method also includes injecting vaporized hydrogen peroxide into air in the chamber to alter a relative humidity of hydrogen peroxide vapor in the chamber to a sterilization level over the first time period. The method also includes maintaining the temperature at the sterilization temperature and the relative humidity at the sterilization level over a second time period. The method also includes reducing the relative humidity from the sterilization level to a safe level over a third time period. In one embodiment, the method is provided for vaporized hydrogen peroxide cleaning of an interior chamber of an incubation container. In other embodiments, the incubation chamber featured in the method is provided.

A lighting assembly for an aircraft includes a visible light source generating visible light and an ultraviolet light source generating ultraviolet light. The visible light source is disposed adjacent to the ultraviolet light source. The visible light source illuminates a first illumination area with the visible light when the lighting assembly operates in a first operation mode. The ultraviolet light source illuminates a second illumination area with the ultraviolet light when the lighting assembly operates in a second mode of operation. The first illumination area substantially overlaps the second illumination area.

A personal, portable, handheld UV light sanitizer (20) having a tubular housing (22) with a UV light source (32) for uniformly radiating a user's hand through a light transmittable outer wall (24) of the housing having a girth and length that enables substantially the entire the exterior surface of the outer wall to be covered by a user's hand when fully grasping the outer wall. A rearward annular wall (41) reduces any rearward light leakage and provides a bearing surface against which the edge of the user's hand may rest to prevent slippage. An annular forward wall (40) reduce forward light leakage and mounts actuation switches (36, 56), remote sensors (58, 60), a status indicator light (61) and an alarm speaker (59). When the skin surface sanitization mode switch (36) is actuated, skin sanitizing UV light radiation (42) radiates the inside of the user's hand for a preselected time period, unless there have previously been an excessive number of past hand sanitization cycles or too little time has passed since the last hand sanitization cycle (FIG. 9). Once energization, it is automatically deenergized after a preselected maximum time period (FIG. 9). Mounted to the front of the forward annular wall is another UV light source (51) that radiates UV light to suspect target surfaces spaced from the user's hand. A range finder (58) helps the user to hold the surface UV light source at the right distance from the target surface for effective sanitization, and energization is immediately terminated in response to an infrared sensor detecting that the surface UV light source is directed at a person's skin.
