A cleaning and sterilizing device includes an ultrasonic cleaner, a top cover and an ultraviolet lamp. The ultrasonic cleaner has a cleaning tank for performing ultrasonic cleaning process to objects. The top cover is disposed on the opening of the cleaning tank and removable at any time. The ultraviolet lamp is installed on the bottom surface of the top cover and directly faces the cleaning tank for providing sterilization effect to the object in the cleaning tank. Therefore, the cleaning and sterilizing device of the present invention is optional to clean the object by ultrasonic cleaning or sterilize the object by irradiating it by the ultraviolet lamp, thereby attaining the objective of thorough cleaning and sterilization. Besides, the top cover with the detachable design brings convenience for adding or pouring the water in the cleaning tank, thereby increasing the usage convenience.

Systems and methods for operating a cart. The methods comprise: receiving an electronic device on a shelf disposed in a main chamber of the cart; supplying power from the cart to the electronic device; transitioning a mode of the cart from a first mode in which a UV lamp is disabled to a second mode during which the UV lamp is to be enabled; detecting, by a computing device, that a door of the cart is in a closed position; causing, by the computing device, an enablement of the UV lamp, responsive to a detection that the door is in the closed position; and using light from the UV lamp to clean the surface of the electronic device while power is being supplied from the cart to the electronic device.

A system for decontaminating the hands of a person is disclosed having a composition with a marker agent capable of luminescence when exposed to light having a wavelength ranging from approximately 315 to 400 nanometers. The composition is disposed in a container capable of receiving the hands of a person therein such that when the hands of the person are placed in the container the hands of the person are immersed in the composition. A water dispenser is provided that operates in conjunction with a light source adapted to emit radiation having a wavelength ranging from approximately 315 to 400 nanometers. A washing event occurs while light is directed towards the location of the washing event.

A method for processing a substrate includes receiving a substrate having fluorinated polymer residue on a surface of the substrate. The fluorinated polymer residue is treated to provide a treated fluorinated polymer residue having increased sensitivity to electromagnetic (EM) radiation exposure. The treated fluorinated polymer residue is treated to EM radiation in an oxygen-containing environment to facilitate a cleaning process for removing the fluorinated polymer residue from the substrate.

The disclosure relates to a device for treating stains, which can be carried by a person, comprising a reservoir for receiving a chemical formulation, where the reservoir has an outlet port for dispensing the chemical formulation and where the device comprises a UV radiation source which emits its radiation in a direction essentially away from the device. The invention further relates to a method for treating spots using such a device.

Systems and methods for cleaning and disinfecting contaminated tube lumens are described herein. One system includes an ultraviolet light source and a sterile fluid reservoir fluidly coupled to a liquid light guide. The system is configured to allow simultaneous access and propagation of ultraviolet light and fluid in a tube having a lumen to be cleaned and disinfected. The light guide can be moved inside the tube and simultaneously emit ultraviolet light through its walls and at its distal end into the interior of the contaminated tube. A flush of sterile fluid from an open end of the liquid light guide removes debris and micro-organism detached from the inner surface during light exposure. The sterile fluid can be a high refractive index ionic solution promoting light propagation.

An apparatus and method for processing substrates. The method includes positioning a substrate within a processing chamber of a substrate processing system. The substrate includes a layer of a carbon-containing material on a working surface of the substrate. The method also includes receiving hydrogen peroxide vapor in a vapor treatment region of the substrate processing system, generating hydroxyl radical vapor by treating the hydrogen peroxide vapor in the vapor treatment region, and directing the hydroxyl radical vapor and remaining hydrogen peroxide vapor to the working surface of the substrate causing the carbon-containing material to be chemically modified.

A device for disinfecting cables and wires for use in cable coiling/pulling machines which, under their operating conditions, are placed in an environment where the cable/wire is exposed to high exposure to bacteria, viruses and microorganisms, such as pipe ducts, having a body including all parts (2 and 3) of the body (1) have at least one supporting element (5), and the front (7) and rear (8) wall of the body (1) have openings (9) and (10), and furthermore it has electromagnetic radiation sources (12) inside the body (1).

A cleaning system includes a mobile base that enables movement of the cleaning system. The cleaning system also includes a camera that captures an image of a cleaning location and an ultraviolet light source that transmits a disinfecting light output toward the cleaning location. Additionally, the cleaning system includes a processor and a memory. The memory includes instructions stored thereon that are executable by the processor to perform operations. The operations include receiving the image of the cleaning location from the camera and determining a distance from the ultraviolet light source to the cleaning location using the image. Further, the operations include determining a cleaning time period of the cleaning location using the distance from the ultraviolet light source to the cleaning location and controlling the ultraviolet light source to transmit the disinfecting light output for a duration of the cleaning time period.

A cleaning and sanitizing apparatus for handheld devices may comprise a cuboid-shaped unit body having a top end and a base end, a slot opening, a user interface and microcontroller system for governing the individual components of the said cleaning and sanitizing apparatus for handheld devices, a gripping and carriage apparatus, a removeable cleaning solution reservoir, a pump and sprayer apparatus for dispensing cleaning solution, a moveable cleaning roller apparatus for cleaning the surfaces of handheld devices as such devices are lowered into and raised from the said unit body, and an irradiation chamber located at the base of the cuboid shaped body including at least one germicidal ultraviolet lamp array housed inside the said unit body. The apparatus may further comprise a wireless induction charging module configured to charge a handheld device while the handheld device is within the enclosure or compartment.
