Abstract: Certain dual roll dispensers and methods of dispensing sheet product are provided. In one example, the method includes receiving, by the controller, a first trigger from at least one motion sensor, where the controller is in an awake state before the first trigger is received. The method includes causing, in response to the first trigger, a measurement device to enter an awake state, where the measurement device is configured to measure an amount of product dispensed by the dispenser. The method also includes receiving dispense event information associated with the amount of product dispensed during a dispense event, and storing or transmitting the dispense event information.

Abstract: Certain dual roll dispensers and methods of dispensing sheet product are provided. In one example, the method includes receiving, by the controller, a first trigger from at least one motion sensor. The method includes determining an active product being dispensed by the dispenser, and powering, in response to the first trigger, a measurement device configured to measure an amount of the active product dispensed by the dispenser. The method also includes receiving, from the measurement device, dispense event information associated with the measured amount of the active product dispensed by the dispenser during a dispense event, and storing the dispense event information.

Abstract: Certain hybrid dispenser systems and methods of dispensing sheet product are provided. In one example, the method includes dispensing, by the dispenser, an exposed tail of sheet product upon activation of a proximity sensor associated with the dispenser. The method includes dispensing a second length of sheet product in response to a user manually exerting a pull force on the exposed tail. The method includes generating electrical energy using an electrical generator of the dispenser. An amount of electrical energy generated by the electrical generator is based in part on the second length of sheet product pulled by the user. The method includes charging an energy storage device electrically coupled to the electrical generator by transferring energy from the electrical generator to the energy storage device, and modifying the pull force the user exerts to dispense the second length by adjusting an energy transfer rate from the electrical generator to the energy storage device.
