Dispenser dosing based on hand size
View Patent ↗Exemplary methods and systems for dispensing soap sanitizer or lotion as a function of hand size are disclosed herein. An exemplary dispenser for dispensing a soap, sanitizer or lotion includes a housing, a processor in the housing, a reservoir for holding fluid, a pump for pumping the fluid and a sensor for sensing a parameter that is indicative of the hand size. The exemplary dispenser also includes circuitry for determining a dose volume of fluid to be dispensed as a function of the sensed parameter that is indicative of a hand size and circuitry for causing the pump to dispense the dose volume.
1. A dispenser for dispensing a soap, sanitizer or lotion, the dispenser comprising:
a housing;
a processor in the housing;
a reservoir for holding fluid;
a pump for pumping the fluid;
a sensor assembly comprising at least two sensors for sensing a parameter that is indicative of a user's hand size;
wherein, after the at least two sensors sense the parameter that is indicative of the user's hand size, the sensor assembly sends a signal to the processor that includes the sensed parameter;
wherein the processor is configured to determine a width of the user's hand based on the sensed parameter of the at least two sensors;
wherein the processor is configured to determine a dose volume of fluid to be dispensed as a function of the determined width of the user's hand;
wherein the processor causes the pump to dispense the dose volume.
2. The dispenser of claim 1 , wherein the dose volume of fluid to be dispensed is selected from a group of dose volumes and wherein the group contains at least two different dose volumes.
3. The dispenser of claim 1 , wherein the processor is configured to determine a length of the user's hand based on the sensed parameter of the at least two sensors, and wherein the processor is configured to determine a dose volume of the fluid to be dispensed as a function of the determined length of the user's hand.
4. The dispenser of claim 1 , wherein at least one of the at least two sensors comprises an image capturing sensor.
5. The dispenser of claim 1 , wherein the at least two sensors comprise a first sensor for measuring a first distance from the first sensor to a first portion of the user's hand and a second sensor for measuring a second distance from the second sensor to a second portion of the user's hand.
6. The dispenser of claim 1 , wherein at least one of the at least two sensors comprises at least two emitters and an array of receivers.
7. The dispenser of claim 1 , wherein at least one of the at least two sensors comprises at least two emitters and at least two receivers.
8. The dispenser of claim 1 , wherein at least one of the at least two sensors comprises one of an infrared emitter, a laser, an electric field and a magnetic field.
9. The dispenser of claim 1 , wherein at least one of the at least two sensors comprises at least one reflective member for reflecting a light source toward a receiver.
10. A dispenser for dispensing a soap, sanitizer or lotion, the dispenser comprising:
a housing;
a processor in the housing;
a reservoir for holding fluid;
a pump for pumping the fluid;
a sensor assembly comprising at least two emitters and an array of receivers for sensing a parameter that is indicative of a user's hand size;
wherein, after the sensor assembly senses the parameter that is indicative of the user's hand size, the sensor assembly sends a signal to the processor that includes the sensed parameter by the at least two emitters and the array of receivers;
wherein the processor is configured to determine a width of the user's hand based on the sensed parameter by the at least two emitters and the array of receivers;
wherein the processor is configured to determine a width of the user's hand based on the sensed parameter by the at least two emitters and the array of receivers;
wherein the processor is configured to determine a dose volume of fluid to be dispensed as a function of the determined width of the user's hand;
wherein the processor causes the pump to dispense the dose volume.
11. The dispenser of claim 10 , wherein the dose volume of fluid to be dispensed is selected from a group of dose volumes and wherein the group contains at least two different dose volumes.
12. The dispenser of claim 10 , wherein the processor is configured to determine a length of the user's hand based on the sensed parameter of the sensor assembly, and wherein the processor is configured to determine a dose volume of the fluid to be dispensed as a function of the determined length of the user's hand.
13. A dispenser for dispensing a soap, sanitizer or lotion, the dispenser comprising:
a housing;
a processor in the housing;
a reservoir for holding fluid;
a pump for pumping the fluid;
a sensor assembly comprising at least one reflective member configured to reflect a light source toward a receiver, wherein the sensor assembly is configured to sense a parameter that is indicative of a user's hand size;
wherein, after the sensory assembly senses the parameter that is indicative of a user's hand size, the sensor assembly sends a signal to the processor that includes the sensed parameter by the sensory assembly;
wherein the processor is configured to determine a width of the user's hand based on the sensed parameter by the sensor assembly;
wherein the processor is configured to determine a dose volume of fluid to be dispensed as a function of the determined width of the user's hand;
wherein the processor causes the pump to dispense the dose volume.
14. The dispenser of claim 13 , wherein the dose volume of fluid to be dispensed is selected from a group of dose volumes and wherein the group contains at least two different dose volumes.
15. The dispenser of claim 13 , wherein the processor is configured to determine a length of the user's hand based on the sensed parameter of the at least two sensors, and wherein the processor is configured to determine a dose volume of the fluid to be dispensed as a function of the determined length of the user's hand.
