Hand-held fluid dispenser system and method of operating hand-held fluid dispenser systems
First Claim
1. A hand grip for an operator of a fluid dispenser system used to dispense a fluid, comprising:
- an enclosure adapted to be held by the operator;
a first proximity sensor disposed inside said enclosure;
a second proximity sensor disposed inside said enclosure; and
an actuation circuit supported inside said enclosure and electrically connected to said first proximity sensor and to said second proximity sensor, said actuation circuit producing an actuation signal in response to sensing a first digit of the operator near said first proximity sensor and a second digit of the operator near said second proximity sensor that is effective to cause the fluid dispenser system to dispense an amount of the fluid.

Abstract
A hand-held fluid dispenser having an enclosure for supporting a container holding a fluid to be dispensed, and a method of operating such hand-held fluid dispensers. A first proximity sensor is located inside the enclosure immediately adjacent one side of the enclosure, and a second proximity sensor is located inside the enclosure immediately adjacent an opposite side of the enclosure. An actuation circuit is supported inside the enclosure and is electrically connected to the first and second proximity sensors. The actuation circuit produces an actuation signal in response to detecting opposed digits of an operator being simultaneously in close proximity to the first and second proximity sensors.

9. A method of operating a fluid dispenser system for dispensing a fluid from a hand grip of the fluid dispenser system held by an operator, comprising:
-
sensing a proximity of a first digit of the operator to the hang grip; sensing a proximity of a second digit of the operator to the hand grip; and causing the fluid dispenser system to dispense the amount of the fluid in response to simultaneously sensing the proximity of the first digit to the hand grip and the proximity of the second digit to the hand grip. - View Dependent Claims (10, 11, 12, 13, 14, 15)
