A dispenser for dispensing sheet product is provided including a housing that defines an interior configured to accommodate a source of sheet product and an outlet through which the sheet product is dispensed. The dispenser also includes a first roller that is rotatable and disposed in the housing. A portion of the sheet product is designed to be in contact with the first roller prior to being dispensed through the outlet. The dispenser also includes a knife drum that is rotatable and configured to cooperate with the first roller to dispense the sheet product. The knife drum includes a knife configured to cut the sheet product into individual sheets. The dispenser also includes a spring assembly that may be configured to bias the knife drum toward a predetermined position during rotation of the knife drum.

Sheet product dispensers and methods of dispensing sheet products are provided, including feeding a sheet material from a roll via a sheet feeding mechanism, separating one or more discrete sheet products from the roll via a separation mechanism, dispensing the one or more discrete sheet products to an end user at a presentation station via a sheet product conveying mechanism, and detecting a presence of the sheet material via a sensor downstream of the sheet feeding mechanism, wherein the sheet product conveying mechanism is driven in response to the sensor detecting the presence of the sheet material.

A sheet material dispenser can include a sheet material transfer assembly operable to automatically transfer feeding or dispensing of sheet material between a plurality of supplies of sheet material. The sheet material transfer assembly can include a frame that is movable between a plurality of positions including a first position that facilitates feeding of the sheet material from a first supply of sheet material, and a second position that facilitates feeding or dispensing of sheet material from a second supply of sheet material. The frame of the sheet material transfer system can shift or move to the second position for dispensing sheet material from the second supply of sheet material when the first supply of sheet material is fully dispensed.

Methods, systems and apparatus for a monitoring system including a plurality of dispensers each configured to be located in a washroom and dispense a respective consumable hygiene product through a dispense cycle, where each of the dispensers is associated with a water source device; a water flow measurement device configured to measure water flow to the water source devices; and a data processing apparatus configured to receive indications of dispense cycles from the dispensers, to receive a water flow measurement from the water flow measurement device, determine which water source device was active by associating one of the water source devices with one of the dispensers based on a first time of the dispense cycle of the one of the dispensers and a second time of the water flow measurement and determine a water flow fault of the one of the water source devices based on the first and second times.

Sheet product dispensers and methods of dispensing sheet products are provided, including feeding a sheet material from a roll via a sheet feeding mechanism, separating one or more discrete sheet products from the roll via a separation mechanism, dispensing the one or more discrete sheet products to an end user at a presentation station via a sheet product conveying mechanism, and detecting a presence of the sheet material via a sensor downstream of the sheet feeding mechanism, wherein the sheet product conveying mechanism is driven in response to the sensor detecting the presence of the sheet material.

Systems, methods, and apparatuses for optimizing performance of a product dispenser are provided herein. Depending on the circumstances surrounding the product dispenser (e.g., the environment, the type or habits of users or individual users, etc.), initial dispensing parameter settings of the product dispenser may be undesirable. Using monitored usage data, optimized dispensing parameters can be determined to achieve more desirable usage of the product dispenser (e.g., decrease waste, power save, increase efficiency, etc.). Additionally, using bounding parameters and/or information from the environment (e.g., nearby product dispensers) can lead to further optimized performance of the product dispenser. User or group specific optimized dispensing parameters can also be determined and used.

An automatic paper towel dispenser includes a dispensing mechanism configured to dispense a paper towel, a light detection and ranging (LIDAR) sensor, and a controller in communication with the LIDAR sensor. The LIDAR sensor is configured to emit light toward an object within a detection region at a first time, detect the light reflected by the object at a second time, and calculate a time of flight of the light. The time of flight is an amount of time that elapses between the first time and the second time. The controller is configured to calculate a distance between the LIDAR sensor and the object based on the time of flight and actuate the dispensing mechanism based on the calculated distance.

A hand dryer includes: nozzles each provided on a wall of a hand insertion portion, transforming a high-pressure airflow from an air blower into a high-speed airflow, and blowing the high-speed airflow into the hand insertion portion. The hand dryer includes: a hand sensor including a plurality of electrode pairs and detecting a hand inserted into the hand insertion portion from a change in capacitance between two electrodes included in the plurality of electrode pairs, each of the plurality of electrode pairs consisting of a first electrode and a second electrode having different polarities to each other; and a controller that drives the air blower on the basis of a combination of the two electrodes with which a hand has been detected by the hand sensor.

A system for monitoring a usage of rolled or stacked disposable sanitary product in a predetermined location or facility and providing information associated with said usage to one or more users, comprising: (a) one or more optical sensors mounted at respective locations associated with where the product is dispensed and configured to monitor a diameter of the roll or height of the stack and transmit data associated therewith; and (b) one or more receivers configured to receive and transmit said data to one or more databases for storage, processing, analysis and/or user notification regarding product usage.

A sheet dispensing apparatus to dispense sheets from a sheet material card having a plurality of sheets. The sheet dispensing apparatus includes a door, a door plate, a back plate, and a motor including a motor shaft, wherein the motor is operatively connected to the door plate, and a motor wheel is operatively connected to the motor shaft. The motor wheel is driven by the motor shaft to detach a sheet from the sheet material card. The apparatus further includes a first light pipe having a first end and a second end, wherein a signal transmitted at the first end of the first light pipe is received at the second end if the correct sheet material card is being used. A second light pipe receives a signal at the first end and receives the signal at the second end, if the sheet material card is not present or out of sheets.
