A dispenser for dispensing sheet product is provided. The dispenser includes a housing with an outlet through which sheet product is dispensed. A knife drum is rotatable with respect to the housing. A knife is movable between a retracted position within the knife drum and an extended position where the knife protrudes outside of the knife drum to cut the sheet product. A cam follower surface is fixed with respect to the housing. A cam follower is attached to the knife and operable to engage the cam follower surface and travel therealong to transition the knife between the retracted position and the extended position. A spring assembly biases the knife drum during rotation toward a predetermined position. The spring assembly comprises a first spring and a second spring. The spring assembly is attached at a single mount position that is fixed with respect to the housing.

The present disclosure is directed to systems and methods that facilitate identifying, logging, mapping, and/or tracking of the movements and/or activities of individuals throughout a facility using a plurality of dispensers are positioned at selected locations about the facility. The systems and methods further allow for capturing infrared radiation of one or more individuals within a prescribed detection range, area, or zone covered using at least one passive infrared radiation sensor. The control system of a dispenser of the plurality of dispensers can be disconnected from a power source of the dispenser when the at least one passive infrared radiation sensor does not capture infrared radiation of one or more individuals within the prescribed detection range, area, or zone. Other aspects also are described.

A wet or dry paper towel dispenser includes a paper towel roll in a housing; drive rollers operably driven by an electric motor; driven rollers disposed oppositely of the drive rollers; a controller including a first sensor for detecting dispensation of dry paper towel sheet and a second sensor for detecting dispensation of wet paper towel sheet; a paper dispensing opening under the controller; a cutter disposed between the paper dispensing opening and the driven rollers, the cutter being configured to cut a portion of sheet product of the paper towel roll; a reservoir disposed rearward of the paper dispensing opening; a pump electrically connected to the controller; and nozzles. A leading edge of the paper towel roll is pinched by the drive rollers and the driven rollers to dispose in front of the nozzles.

The present disclosure is in one aspect to a dispenser for rolled sheet materials. The dispenser includes a feed roller that is rotatably mounted to a housing of the dispenser housing, and that is configured to feed a predetermined amount of sheet material from the supply of sheet material through a discharge provided along the housing of the dispenser. The dispenser also has a feed roller drive assembly with a drive motor, and a belt transmission assembly. The belt transmission assembly has a drive belt coupled to the drive motor and to the feed roller such that rotation of the feed roller is driven by operation of the drive motor.

A light ring assembly for a bathroom fixture. The light ring may illuminate one or more light sources in a predetermined sequence and/or in an overlapping manner to create a pulse of light that traverses the circumference of the light ring. Different patterns, colors, and/or sequences of light may be used to convey messages and signals to owners, maintenance, and/or users.

A power management system for a dispenser that includes a passive infrared radiation sensor arranged along the dispenser and configured to detect infrared radiation emitted by one or more users within a prescribed detection range, area, or zone of the dispenser. When the passive infrared radiation sensor does not capture infrared radiation within the prescribed detection range, area, or zone, the dispenser is placed in a low power state with the passive infrared sensor remaining connected to a power source and a controller, a dispensing mechanism, and/or the proximity sensor being disconnected from the power source. Other aspects also are described.

A dual roll paper towel dispenser, a method of dispensing towel from a dual roll paper towel dispenser, and a method of servicing a dual roll paper towel dispenser are disclosed herein. The dual roll paper towel dispenser can be provided with a dispenser mechanism disposed in a dispenser housing. The dispenser mechanism can include a first drive roller for dispensing paper from an upper first roll of paper and a second drive roller for dispensing paper from a lower second roll of paper. The dispenser mechanism can further include a drive system including a motor for selectively operating the first drive roller and the second drive roller, wherein the drive system powers the motor in a first rotational direction to actuate the first drive roller and powers the motor in a second rotational direction opposite the first rotational direction to actuate the second drive roller.

A dispensing system for dispensing consumable product comprising a dispenser including a body comprising a front side and aback side, and a product holding area defined by the front side and the back side, wherein the product storage area is configured to store the consumable product within the dispenser; a dispensing mechanism operatively coupled to the consumable product through a consumable product holder in the product storage area, and wherein the dispensing mechanism is configured to facilitate a dispensing cycle to dispense a portion of the consumable product; a first impact sensor configured to sense a first impact to the dispenser; a dispenser event sensor configured to sense an operational status of the dispenser; and a data processing device configured to store impact data describing the first impact and operational status data describing the operational status and associate the first impact data and the operational status data.

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.

Disclosed are various examples of automated dispensers to dispense consumable products, such as paper towels, gels, liquids, gases, aerosols, foams, and other consumables. Automated dispensers can operate in various modes. Examples of the disclosure can utilize a dispense profile to adjust the speed at which consumable products are dispensed.
