１つのセルで作動し且つバッテリバンキング機能を備えるタッチフリーのディスペンサ

摘要

An electrically powered device includes at least one electrically powered component and a power source having at least two cells. One cell powers the electrically powered component and the remaining cells are held in reserve. A control circuit is connected to the electrically powered component and the power source. The control circuit includes a controller which generates a charge signal, a boost regulator circuit connected to the controller which receives power from the power source and generates a boost signal for conversion into a charge signal. A capacitor is connected to the controller and receives the charge signal and provides a predetermined voltage to the electrically powered component. A boost regulator circuit and the controller monitor the power source and draw power from one of the remaining cells held in reserve when the cell is fully depleted.
