Patent number: 11930970Abstract: Exemplary power systems for dynamically controlling a dispenser drive motor for dispensing soap, sanitizing or lotion. An exemplary soap, sanitizing or lotion dispenser includes a housing, a receptacle for receiving a container for holding a soap, sanitizing or lotion, a container of soap, sanitizing or lotion and a pump secured to the container. The exemplary soap, sanitizing or lotion dispenser includes a power source, a motor and an actuator that couples the motor to the pump. In addition, the exemplary soap, sanitizing or lotion dispenser includes pulse width modulation circuitry in circuit communication with the power source and the motor. Movement of the actuator one actuation cycle dispenses a dose of soap, sanitizing or lotion. The pulse width modulation circuitry provides a plurality of voltage pulses to the motor to move the actuator one actuation cycle.Type: GrantFiled: November 17, 2022Date of Patent: March 19, 2024Assignee: GOJO Industries, Inc.Inventors: John J. McNulty, Donald R. Harris, Mark A. Bullock, Chip W. Curtis

Patent number: 11819171Abstract: Exemplary soap, sanitizer and lotion dispensers are disclosed herein. An exemplary dispenser includes a housing; a receptacle for receiving a container; a container of fluid comprising soap, sanitizer or lotion; a pump in fluid communication with the container; a power source; a pump coupled to a motor and pulse width modulation circuitry in circuit communication with the power source and the motor. The pulse width modulation circuitry is initially set to cause a selected dose of fluid to be dispensed at a base speed. A sensor for detecting a parameter indicative of an actual speed of a dispense of the fluid is also included. When the actual speed of the dispense of fluid is less than the base speed or greater than the base speed, the pulse width modulation circuitry adjusts the pulse width to cause the speed of a following dispense of fluid to be closer to the base speed.Type: GrantFiled: June 2, 2022Date of Patent: November 21, 2023Assignee: GOJO Industries, Inc.Inventors: John J. McNulty, Nick E. Ciavarella, Daniel M. Willis, Aaron D. Marshall, Donald R. Harris
