A device for cleaning interproximal spaces between teeth. The device includes a coupling body having a coupling portion for removably coupling with a handle apparatus. An interdental member extends from the handle apparatus. Energy is transferred from the handle apparatus to the interdental member. The interdental member has a profile for fitting within and cleaning an interproximal area. The interdental member is formed from a flexible polymer material.

In various embodiments, the device may be used to clean any brush. The brush bristles carry bacteria, food particles, dust, germs, and other similar residue in tightly packed spaces near where the bristles connect with the head of the brush. In multiple embodiments, the device is a container that is filled with cleaning solution (e.g., mouthwash, cleaning solution, alcohol, etc.), a lid that substantially closes the top opening of the container, and an agitator pad that has a plurality of individual prongs. In various embodiments, the lid mirrors the container shape so that the lid and the container can be operatively connected. In various embodiments, the lid has a cover, so that when the device is not being use, the cover may be put in a closed position so that the cover closes the opening in the lid.

An automatic and currentless dirt remover for collecting dirt from the area surrounding the dirt remover, having a dirt-collecting body and a rolling-action sheath body, which defines a receiving space for receiving the dirt-collecting body. The sheath body has openings for providing external access to the dirt-collecting body, which has a surface that collects the dirt.

A cleaning and maintenance multi-tool for electronic devices is provided, which includes multiple tools in a single body, where the tools are capable of cleaning different components of mobile electronic devices such as smart phones, tablets, digital cameras, laptop or PC computers, or the like.

A cleaning nozzle includes an inner nozzle housing having a feed passage for carrying cleaning fluid, a plurality of nozzle tips that each define a discharge opening in fluid communication with the feed passage, and an outer nozzle housing received over the inner nozzle housing. The outer nozzle housing includes a plurality of outer nozzle extensions that each extend over one of the nozzle tips. The outer nozzle extensions can be inserted into ports of an adapter, and flow of the cleaning fluid through the nozzle is split between the nozzle tips so that multiple optical connectors that populate the adapter can be cleaned simultaneously in a substantially uniform manner.

A wiping device for wiping an optical element clean of water or of particles includes a housing and a wiping element able to undergo a movement with respect to the housing, where the wiping device is configured to move in such a manner that such movement is caused by coupling a first unit in or on the wiping element with a second unit in the housing via a time-variable electromagnetic field. The wiping device may be used for wiping the surface of a lens or of a window, which lens or window is transmissive to visible light, ultraviolet radiation, and/or infrared radiation, and is preferably placed in front or as part of a camera. In addition, a rear view device or driver assistant device for use in or on a vehicle including such a wiping device, and a method for wiping an optical element are provided.

The present invention describes an insulator stack cleaner to remove dust and dirt from power line transmission insulators. The cleaner autonomously cleans an insulator stack. The cleaner has two cleaning cups that counter-rotate during cleaning. The cleaner moves along an insulator stack by opening one cleaning cup while the other cup is locked onto an insulator, then the cleaner's transitional motors somersault the open cup onto the next insulator in the stack, and the open cup subsequently closes around the next insulator. A rack and pinion mechanism rotates the closed cup around an insulator and a cam mechanism opens and closes the cup around an insulator. Bristles on the cleaning cups scrub the insulators. The cleaner can be installed onto an insulator stack by a drone.

Methods and apparatus for cleaning a central venous catheter port are disclosed. An apparatus includes a body, a coupling configured to connect the body to the hub, a cleaning cap coupled to the body, and an actuator disposed within the body for rotating and translating the cap relative to the hub. The cleaning cap includes a cap body defining a cavity and a cleaning member disposed within the cavity, the cleaning member having threads that engage with the threads on the hub.

A washing system that includes a vessel for storing a cleaning solution, an inlet connection point for pressurizing the vessel, and an outlet connection point for dispensing the cleaning solution. In one embodiment, the washing system includes a regulator valve configured to remain open and allow the inside of the vessel to be filled with pressurized gas via the inlet connection point when pressure inside the vessel is below a predetermined value and automatically close when pressure inside the vessel exceeds the predetermined value. In another embodiment, the washing system includes a relief valve (e.g., at the top of the vessel) that is configured to remain closed when pressure inside the vessel is below a predetermined value and automatically open when pressure inside the vessel exceeds the predetermined value.
