METHODS FOR MANAGING POWER CONSUMPTION FOR A HANDS-FREE DISPENSER

摘要

Methods for managing power consumption of a battery-powered device such as a fluid dispenser are disclosed. One method includes setting a duty cycle of a sensor used by the device to a first range and setting a timer upon detection of a triggering event and also setting the duty cycle to a triggering event and also setting the duty cycle to a second range. The method continues by checking for another triggering event during the second range. The checking step is repeated if the timer has not lapsed, but if the timer has lapsed the process returns to the setting step. Related methods may be used to adjust the duty cycle based upon a detected characteristic such as light, sound, motion or time.

1. A method for managing power consumption of a battery-powered device, comprising:
providing a battery-powered device that must remain in a condition to detect the presence of a user with a sensor so as to dispense a product, wherein detection of the user is a triggering event; setting a duty cycle of said sensor to a first range; starting a timer, setting said duty cycle to a second range, and dispensing the product upon detection of said triggering event; checking for the presence of another triggering event with said duty cycle to set to said second range; repeating the checking step if said timer has not lapsed; and returning to said setting said duty cycle of said sensor to said first range when said timer has lapsed.
