Abstract: A system and control method for an electronic liquid dispenser utilizes a motor to drive a pump mechanism from a home position in a dispense cycle for dispensing a metered dose of liquid from a reservoir. Upon initiation of the dispense cycle, the motor is started to operate the pump mechanism. Motor work performed by the motor during the dispense cycle is calculated as a function of motor current, motor voltage, and run time of the motor. Upon the calculated motor work exceeding a set point value during the dispense cycle, the motor is stopped and reversed to return the pump mechanism to the home position.

Abstract: The present invention provides a dispenser for dispensing pre-cut sheets from a roll or a web material to a user in need of the web material. The dispenser contains a product identification sensor in communication with a control circuit. This product identification sensor detects and identifies information about the roll of the web material placed in the holder and relays this information to the control circuit. The control circuit adjusts dispensing parameters for the actuator roller in dispensing a sheet of the web material from the dispenser.

Abstract: The present invention provides a dispenser for folded sheets having an overfill prevention device, which effectively prevents the dispenser from being overfilled with folded sheet material. The result of the present invention is that a maintainer of the dispenser will have a difficult time overfilling the dispenser.

Abstract: The disclosure herein provides a roll support system for a rolled web material dispenser which ensures that the proper rolled web material is installed in the dispenser and that the rolled web material is properly aligned in the dispenser. The system limits the size of the core or core plug that can be supported by the support in a towel dispenser. Also disclosed is a system to provide different sized roll caps and supports to ensure that the dispenser is dispensing web material which the dispenser as designed to dispense.

Abstract: The present invention provides a dispenser for dispensing a fluid which has an anti-drip feature. To achieve this anti-drip feature, the dispenser is provided with a suck back mechanism which is separate and independent from a pump in the dispenser. The suck back mechanism uses a resilient member capable of storing fluid.

Abstract: Disclosed is a sanitary or no-touch dispenser which dispenses sheets of a web material, such as a paper towel. The disclosed dispenser provides the web material to a user by using both manual and electronic means to dispense the sheet. This is accomplished by having a motor engagably connected to an actuator roller. The motor is activated by a motor activation means, such as a switch. The motion of the actuator roller, which is started by the user grabbing and pulling a tail of the web material extending from the dispenser, causes the motor activation means to activate the motor which in turn drives the actuator roller to continue it its rotation motion to dispense the sheet from the dispenser.

Abstract: The present invention provides an easy to maintain dispenser which will dispense an appropriate amount of fluid to effectively clean a user's hand, even if the dispenser is inactive for a period of time. Also disclosed is a method of dispensing a fluid from the dispenser.

Abstract: An apparatus for the dispensing of product is provided. The apparatus may include a dispenser sensor unit in communication with a dispenser that is configured for the dispensing of product. The dispenser sensor unit may be configured for detecting information about the product and for varying a dispensing parameter of the dispenser. A data communications unit in communication with the dispenser sensor unit may also be provided and may be configured for receiving information from the dispenser sensor unit. A washroom monitoring station in communication with the data communications unit may also be present and may be configured for receiving information from the data communications unit. The dispenser sensor unit may be configured for receiving a communication so as to vary a dispensing parameter of the dispenser.

Abstract: A sheet material dispenser includes a controller for automatically controlling the lengths of sheet materials dispensed from a continuous roll by identifying the type of sheet materials on the roll and dispensing suitable lengths of the identified sheet material. The dispenser desirably has a support for rotatably supporting a roll of sheet material carrying identification relating to the type of sheet material on the roll, and an identifier positioned in or adjacent the dispenser for identifying the type of sheet material on the roll. A processor receives data from the identifier, processes the data and generates an output command, and a controller controls the lengths of sheet material dispensed from the roll in response to the output command. In this way, more absorbent products may be dispensed in shorter lengths and less absorbent products may be dispensed in longer lengths.
