A panel cleaning system is provided which includes an inflatable wiper and a nozzle. In one aspect, the panel cleaning system includes pressurized air, linear actuators, and a panel-cleaning inflatable wiper wherein the pressurized air and the panel-cleaning wiper are configured to clean PV panels. A further aspect includes an inflatable wiper, a heater configured to heat pressurized air before the air flows out of nozzles and multiple air-driven pistons.

A method of performing at least one of a cleaning, buffing, and polishing action on a surface, without requiring water, comprises providing a core member having a plurality of C-shaped grooves having respective openings and at least one sheet of material. The at least one sheet of material comprises a closed-cell silicone foam rubber and is attached to the core member using a coil-shaped element and has a first free end portion extending away from the core member. The core member moves by rotation in a first direction such that a portion of the at least one sheet of material is brought into sliding contact with the surface in a repeating pattern. The sliding contact between the at least one sheet of material and the surface occurs under a pressure and relative velocity sufficient to generate a force that results in at least one of a cleaning, buffing, and polishing.

A single piece device enables medical clinicians to clean and disinfect both an injection port (needleless I.V. connector) and a vascular access catheter hub. The device has a body with a first end having a blind hole with a wall adapted to be engageable with the threads on the housing of an IV connector and a bottom surface adapted to engage the top surface of the IV connector. The device body has a second end defining a male-luer slip extending out of a recess. The male-luer slip is adapted to extend into a standard vascular access catheter hub such that it engages the inner walls of the catheter hub, and the recess is adapted to receive and be engageable with the outside thread element of the catheter hub.

The present invention prevents or alleviates cleaning unevenness in cleaning of a substrate with the use of a roll cleaning member having protruding members. The roll cleaning device includes: a substrate support member that supports and rotates a substrate W; and an upper roll cleaning member (52) for scrub cleaning a surface of the substrate W which is rotated by the substrate support member, while rotating. The upper roll cleaning member (52) has a plurality of protruding members provided thereon that are arrayed in the longitudinal direction thereof, and slidably contact the surface of the substrate W. The roll cleaning device cleans the substrate W so that the trajectories of high cleaning force regions out of the parts of the protruding members which slidably contact the substrate W are present without a gap in a radial direction of the substrate W.

A wiper system incorporates a wiper motor provided with a wireless interface to provide electric power and control signals to the wiper motor. Thus, a direct electric/signal wire connection to the wiper motor is eliminated. A wireless transmitter may be provided within a first body portion of a vehicle and a wireless receiver and a wiper motor are provided in a second body portion of the vehicle. The second body portion may be moveable relative to the first body portion, such as, for example, a lift gate moving relative to a body opening.

A roof-rack for a vehicle and method of operation where the siderails and the crossbars are both automatically movable via a control circuit to clear snow from a vehicle roof.

A scouring article including a monolithic nonwoven pad with a semi-densified fibrous layer that is integral to the monolithic nonwoven pad and that provides a major surface of the monolithic nonwoven pad, and methods of making and using.

A cleaning pad with a reinforcement layer and a method for making the same. The cleaning pad has a first layer of material with an adhesive applied to a first side of the first layer. A second layer of the first material is then applied over the adhesive. An imprinting device then pressed into the cleaning pad to give the pad a textured surface. In addition, more layers of material can be added to the cleaning pad. By adding another layer of adhesive to the cleaning pad then applying more layers material the cleaning pad can be made of any thickness desired. By adding a second adhesive to a select number of sheets of the cleaning pad a core is created. Any number of cleaning pad sheets can then be rolled onto the core to create a roll of cleaning pads.

A device for absorbing, signaling and picking up a product on a floor, the device including: a slender hollow body whose inner walls define a storage volume in which is stored a powder able to absorb the product, where the storage volume opens through an opening for pouring the powder by gravity; a stand on which one end of the body is mounted for forming a signaling marker, where the stand includes a substantially flat base projecting radially relative to the body in order to place the device stably on the floor; and wherein the base includes at least two detachable parts which can be used for picking up a residue formed by the powder and the product.

An apparatus and a method for cleaning a partial area of a substrate, in particular a photomask, are described. The apparatus has a cleaning head having a lower surface configured to be arranged above and in close proximity to the substrate area to be cleaned, the lower surface having a central opening formed therein, a first annular groove, surrounding the central opening, and at least a second groove, arranged between the first annular groove and the central opening, the first annular groove being fluidly connected to a first port allowing connection to an external supply source and the second annular groove being fluidly connected to a second port allowing connection to an external supply source, a tape supply mechanism arranged to supply an abrasive tape to the central opening in the lower surface of the cleaning head, such that a portion of the abrasive tape protrudes therefrom and a liquid media conduit having an outlet arranged to supply a liquid to a backside of the abrasive tape at or at the vicinity of the central opening. In the method a protruding portion of an abrasive tape, which protrudes from a central opening of a cleaning head is placed in contact with the area of the substrate to be cleaned to thereby bring a lower surface of the cleaning head in close proximity to the substrate area to be cleaned. A liquid is supplied to a backside of the abrasive tape at or at the vicinity of the central opening of the cleaning head, such that at least the portion of the abrasive tape protruding from the central opening is wetted, and a relative movement is caused between the abrasive tape and the surface area of the substrate to be cleaned. The method also encompasses applying a cleaning fluid to the substrate area to be cleaned via at least one first groove or the at least one second groove in the lower surface of the substrate and applying a suction force to the other groove.
