A hand cleaning device, including a main body, including a cleaning section to store at least one liquid therein, and a drying section disposed on at least a portion of the cleaning section to facilitate movement of air therein, a cleaning unit disposed on and within at least a portion of the cleaning section to spray at least one liquid within the cleaning section in response to detecting movement within the cleaning section, a scrubbing unit disposed within at least a portion of the cleaning section to scrub using a cleaning agent, and a drying unit disposed within at least a portion of the drying section to blow the air within the drying section in response to detecting movement within the drying section.

The one use toilet paper dispense system is to encapsulate folded toilet paper squares within a 3 inch by 3 inch individual sealed package with a tear line indicated on one corner.

An example system includes a manipulation device, a sensor device and a control module. The control module may be configured to receive information from the sensor to accurately control movement of the manipulation device. The control module may also mimick functionality of a human arm and hand to allow a user to perform a variety of tasks that the user usually does with his own arms and hands.

According to an exemplary embodiment, a dispenser for rolled paper product includes a first arm and a second arm, with the first arm having an elongate member configured to receive a roll of paper product. A first mounting bracket is configured to rotatingly couple the first arm to a mounting surface. The first arm is configured to cover the first mounting bracket from view. A second mounting bracket is configured to rigidly couple the second arm to the mounting surface.

A system for optimizing a timing of a flush valve is provided. The system includes a flush valve comprising a flow area and a solenoid configured to open the flush valve, at least one pressure sensor configured to measure a pressure in the flush valve, and at least one controller in communication with the at least one pressure sensor and the solenoid. The at least one controller is programmed or configured to control the solenoid to open the flush valve for a flush time in response to a flush request, measure a pressure in the flush valve to obtain at least one flush valve pressure, adjust the flush time based at least partially on the at least one flush valve pressure, resulting in an adjusted flush time, and control the solenoid to open the flush valve for the adjusted flush time in response to a flush request.

A rolled paper dispenser having a first arm having a cavity; a second, spaced apart, arm that includes one of an extension and a notch; and an elongated paper holder extending between a first end, which is coupled to the first arm, and a second end, which has the other of the extension and the notch to couple to the second arm in a closed position and to decouple from the second arm in an open position, the paper holder comprising a tubular member and a fastener, the tubular member having an outer surface, which is configured to receive a rolled paper product, and an inner surface, which defines a longitudinal bore in which the fastener is disposed, the fastener extending beyond the tubular member at the first end to engage the cavity to couple the paper holder to the first arm.
