In accordance with one embodiment, the cleaning members are distributed along the longitudinal axis. Also disclosed is a floor cleaning machine that includes a mobile body, the cleaning tool and a motor. The mobile body supports the cleaning tool and the motor and is configured to travel over a surface. The motor is configured to drive a rotation of the cleaning hub about the longitudinal axis.

Abstract: A cleaning system includes a supply of purified water, a supply of cleaning agent, a mixing junction, and a distributor. The mixing junction is configured to combine a flow of the purified water and a flow of the cleaning agent and output a flow of cleaning liquid comprising the flows of the purified water and the cleaning agent. The distributor includes an output through which the cleaning liquid can be discharged. In a method of cleaning a surface, flows of purified water and cleaning agent are provided. The flow of purified water and the flow of cleaning agent are mixed to form a flow of cleaning liquid. The flow of cleaning liquid is then discharged to the surface.

Abstract: In a method of communicating data from a mobile floor cleaner to a remote receiver a data communication is initiated from a communicator of the mobile floor cleaner to the remote receiver and data is communicated to the remote receiver with the communicator.

Abstract: The invention is directed to an aggregate floor coating and method/system for applying the same. In one embodiment, a base layer of epoxy or equivalent material may be applied to a prepared floor surface. Prior to curing of the base layer, a quantity of aggregate flooring material, e.g., quartz particles, may be broadcast over the exposed surface of the base layer. Upon curing of the base layer, an ultraviolet (UV)-curable topcoat layer may be applied. Exposure of the UV-curable topcoat layer to one or more specific wavelengths of UV energy results in fast curing of the topcoat layer, permitting quick resumption of floor traffic. Coatings of the present invention provide numerous advantages, such as allowing application of aggregate floor coatings in well-lit, e.g., sun-exposed areas.

Abstract: A hard surface cleaner includes a motorized scrub head, a fluid recovery device, a primary cleaning liquid component container, a cleaning agent container, a flow control device and a fluid flow path. The flow control device is configured to supply a flow of cleaning agent from the cleaning agent container at a flow rate of less than approximately cubic centimeters per minute to a flow of primary cleaning liquid component from the primary cleaning liquid component container. The fluid flow path is configured to receive a flow of cleaning liquid, which comprises the cleaning agent and the primary cleaning liquid component.

Abstract: A surface cleaner includes a liquid dispensing system comprising a fluid flow path configured to receive a flow of liquid, a pump, an air purging component, and a valve actuator. The pump is in line with the fluid flow path and is configured to drive the flow of liquid through the fluid flow path. The air purging component includes an inlet in line with the fluid flow path, an outlet, an airflow path connecting the inlet and the outlet, and a valve in line with the airflow path. The valve includes an open position in which the airflow path is open between the inlet and the outlet and a closed position in which the airflow path is closed between the inlet and the outlet. The valve actuator is connected to the valve and is configured to bias the valve in the open position when air is detected in the fluid flow path.

Abstract: A sanitation device includes a mobile body, a surface cleaning component, and a source of UV radiation. The surface cleaning component and the source of UV radiation are mounted to the mobile body, which is configured to travel over a surface. The surface cleaning component is configured to engage the surface and the source of UV radiation is configured to direct UV radiation to the surface.

Abstract: A method and apparatus for destroying blood borne pathogens is disclosed which utilizes a low intensity direct current to generate positive particles from various metals which destroy viral pathogens. A first electrode comprised of a metal such as silver is inserted into a patient's venous system. Then, a second electrode is placed on the patient's exterior in the vicinity of the first electrode. A low intensity direct current is applied to the first metal electrode which releases silver cations to be bonded to the virus, resulting in the denaturing of the virus. The first electrode is placed in the venous system of the infected patient via a catheter.

Abstract: A flushing device comprises a catheter guidewire flushing apparatus comprising a connector having an insertion port, an outlet port and a flushing port and a catheter having rails extending the length thereof. The invention allows a clinician to adjust the length of a catheter, to insert the catheter while flushing to maneuver the catheter through a tortuous blood vessel, and to easily remove the guidewire for safe disposal. The catheter can then be left in place in the blood vessel.

Abstract: A dual lumen vascular catheter with expanding side portal includes a cylindrical tubing with one or more lumens inside. An effusion portal is located on the side of the tubing at an end of one lumen. The portal is oval-shaped, with an open-ended slit connected to an end of the oval opening. The slit is thereby expandable, allowing for vacuum relief during aspiration of blood in the event that the catheter is lodged with the portal pressed against an inner wall of the vein.

Abstract: This invention relates to a "plungerless" means of drawing blood and for administering liquids via parenteral injection. This means is used in conjunction with a pouch bearing an injection means, to which it is releasably attached. It comprises hinged plates which, when folded, expand the pouch; and which, when straightened, compress it.In a preferred embodiment, the plates fold along a line essentially parallel to the general direction of fluid flow, and extend beyond the distal end of the pouch. The expanded pouch may then be rested on the distal edges of the plates, which form a "diamond" configuration.
