A hook with two curved portions collectively forming an openable pressure surface.

A method may include receiving, from a first restroom appliance of a plurality of restroom appliances arranged in an environment, environmental data comprising an ambient light level, the first restroom appliance comprising a sensor configured to detect the ambient light level and a communication device configured to transmit the ambient light level; determining, with at least one controller, an adjusted infrared pulse frequency based on the ambient light level received from the first restroom appliance; and modifying, with the at least one controller, an infrared pulse frequency of a second restroom appliance of the plurality of restroom appliances based on the adjusted infrared pulse frequency.

A device for drying feet and/or footwear, having a casing with at least one opening for the inflow of air into the casing; an upper surface of the casing for receiving the sole of the foot and/or footwear, with at least one lower hole for the outflow of air from inside the casing to the exterior contacting with the sole of the foot and/or footwear; lateral walls projecting from the upper surface, with at least two lateral holes for the outflow of air from inside the casing; and a motor that absorbs air through the air inflow opening expelling it through the air outflow holes, wherein the lateral holes are located at least at two different heights with respect to the upper surface of the casing in order to expel the air over the sides and the instep of the foot and/or footwear.

An apparatus for drying hands has an ultrasound generator providing an ultrasound electrical voltage, and a piezoelectric transducer connected to the ultrasound generator and generating acoustic waves which create friction on a surface of hand and thereby dry the hands in a noiseless manner, and a method of drying hands is implemented by the apparatus

A paper cutting device includes a support frame, first rotating shaft and cover. The support frame is defined with an accommodation space with a forward opening, and the two ends of the accommodation space are in combination with two side plates in opposite to each other; the first rotating shaft is configured between the two side plates and positioned in the accommodation space, allowing the first rotating shaft to be rotated in the accommodation space; the cover is in movable combination with the two side plates of the support frame and positioned relatively at the forward opening of the accommodation space, the cover adapted to cover the first rotating shaft. Furthermore, a knife assembly is mounted in a breach configured on the first rotating shaft, and protruding shafts configured on the two ends thereof can be slid in corresponding closed annular guide grooves configured on the two side plates.

A method for removing eye makeup comprises: providing a makeup removal cloth comprising a bamboo fabric having an interlock knit; moistening the makeup removal cloth with water or a makeup removal fluid; positioning the makeup removal cloth at an inner portion of an eyelid or under eye region of the user; and moving the makeup removal cloth from the inner portion of the eyelid or under eye region to an outer portion of the eyelid or under eye region.

Dry, plied roll paper is transformed into hand wetted roll paper that may be used either dry, or selectively hand wetted using the device of the invention. The device is applied to the paper in liquid form, heated and cooled to form a plastic solid which becomes part of the paper. The device is then shaped into a container filled with an anti-bacterial cleaning agent, or other agent, and assembled on the paper between the top and bottom paper ply. The device is made on a modified roll-to-roll winding machine while the machine is in motion. This manufacturing method is more efficient than adding externally sourced batch-made wetting devices to paper. The hand wetted roll paper can be used as paper towels or toilet paper for dry and/or wet hygienic cleaning. The paper may have other properties depending on the agent used.
