Surface disinfection for enclosures with Ultra-Violet (UV) light and illuminating such enclosures with visible light. Particular embodiments relate to limiting the transmission of viruses and bacteria in the interior space of an aircraft, such as a lavatory, through the use of UV light application, while providing visible light to passengers of such lavatory, both in a safe and compliant manner. This disclosure provides a lighting system and method that combines a visible light emitter and a UV light emitter into a single light system module. Although UV light is a preferred method of neutralizing pathogens, its use is not safe for human exposure. Accordingly, the disclosed lighting system is capable of detecting the presence of an occupant within an enclosure or defined space and only allows the visible light emitter to function (and prevents the UV light emitter from functioning) while people or animals are present within the electromagnetic range for the lighting system. The lighting system can then detect the absence of an occupant within an enclosure or defined space, prior to activating the UV light emitter, and once absence is detected, the UV light emitter can be activated by a controller.

A method and device for the remote eradication of pathogens comprising a light source for emitting UV light in the pathogen killing wave length range, and a tangible transmission medium, which is at least initially resistant to degradation by the UV light. An optical interface between the UV light source and the tangible transmission medium is provided whereby the emitted UV light is collected from the light source and transmitted through the tangible transmission medium, whereby UV light emitted from the tangible transmission medium and directed against a pathogen in proximity thereto is at a power level sufficient to substantially effectively kill the pathogen within a reasonable period of time. The device is used for sanitization of biopsy channels of endoscopes and for treating of pathogens within humans and animals.

A secure box for receiving packages is described. The secure box includes a rectangular container with a top, a bottom, a front, a left, a right, and a back. A front door forms part of the front when in a closed position, the front door having at least one hinge allowing it to move to an open position by swinging outward at a top end. A top cap with one or more photovoltaic panels formed therein, the top cap adapted to securely fasten onto the top. A package sensor senses a package placed in the rectangular container to initiate a decontamination process. A controller is electrically coupled to one or more photovoltaic panels, and the controller is communicatively coupled to the package sensor to control a decontamination system for decontaminating the package which has been sensed. The decontamination system includes at least one of ultraviolet light source, a chemical spray, or both.

An assembly for redirecting light emitted by an end-emitting optical fiber into an inner lumen of a body is provided. According to one implementation, the body includes one or more surfaces disposed on or in the body onto which the light is configured to impinge when the end emitting optical fiber is activated, the one or more surfaces being configured to alter the trajectory of the light so that the light is directed to impinge on a light reflector of a cap removably attached to the body, the light reflector of the cap being configured to redirect the light distally into the inner lumen of the body.

A method of sterilizing an article includes receiving the article in a sterilization chamber. The method also includes applying a vacuum to a first pressure less than 100 torr. The method also includes introducing a sterilant into the sterilization chamber. The method also includes maintaining the first pressure in the sterilization chamber for a first period of time. The method also includes venting the sterilization chamber to a second pressure less than 100 torr. The method also includes maintaining the second pressure. The method also includes venting the sterilization chamber to a third pressure. The method also includes maintaining the third pressure. The method also includes venting the sterilization chamber to atmospheric pressure. The method further includes between venting and maintaining steps applying a vacuum to a fourth pressure less than 100 torr, introducing additional sterilant, and maintaining the fourth pressure.

A sanitization apparatus may comprise a light source configured to emit a light having a first wavelength between 414 and 474 nm; a nonlinear crystal disposed proximal to the light source, the nonlinear crystal configured to receive the light having the first wavelength and output a first portion of the light having the first wavelength and a second portion of the light having a second wavelength, the second wavelength being half the first wavelength; and a prism configured to receive the first portion of the light and the second portion of the light, the prism configured to direct the second portion of the light toward a surface to be sanitized.

A system and method for a UV disinfection device configured to be disposed to direct UV energy through an exit interface toward a target surface of a device. The UV disinfection device may be configured for low-profile distribution of UV energy toward the target surface.

An ultraviolet device is provided, which includes a gas jetting module, a flow rate adjustment module, an ultraviolet module and a first gas channel. The gas jetting module includes an upper panel, a lower panel and a frame. The upper panel is disposed on the upper side of the frame. The lower panel is disposed on the lower side of the frame and includes one or more gas outlets. A gas chamber is formed between the upper panel, lower panel and frame. The first gas channel is connected to the gas jetting module. The flow rate adjustment module is connected to the first gas channel and adjusts the flow rate of the gas inputted into the gas chamber via the first gas channel. The ultraviolet module includes an ultraviolet light source and is connected to the gas jetting module.

A touch input device includes a container body internally defines a receiving chamber, a touch handle, and a disinfection member received in the receiving chamber for disinfecting the touch handle. The touch handle includes a handle portion and a touch portion, which are made of an electrical insulation material and an electrical conducting material, respectively. The handle portion has a part located in the receiving chamber to serve as an insertion section, and another part of the handle portion is exposed from the receiving chamber to serve as a grip section. The touch portion includes two connected touch sections, one of which is fitted on around the insertion section while the other one is connected to the grip section. When a user grips the touch handle to operate a touch electronic device, current in the user's body flows to the touch portion to increase the convenience in using the touch electronic device.

A device including a body section, the body section comprises a mesh material, the mesh material having an interlaced structure sufficient for blocking ultraviolet (UV) light rays; a frame implement, wherein the frame implement being configured to coil inside the body section to provide a supporting structure for the body section to popup when in use or for the body section to be collapsed for storage; a plurality of ultraviolet (UV) lights for sanitizing or disinfecting; a lid portion; and a fastener, wherein the fastener is configured to connect the lid portion to the body section.
