Abstract: A power optimization electronic cigarette device is configured to be reusable for a limited number of refills through use of an easily accessible liquid refilling structure, before ultimately becoming disposable. The electronic cigarette device takes advantage of multiple heating wires that can be selectively operated to vaporize the liquid solution. The selective use of one heating wire, from two or more heating wires serves to extend the life span thereof. A sensor detects the air flow generated from inhaling through the electronic cigarette and triggers the heating wires to generate heat while the electronic cigarette is in use. In another power optimization function, the electronic cigarette device comprises a circuit board that detects available power in a battery, and an illumination member that variably illuminates to indicate remaining battery power. The electronic cigarette also provides a USB charging port for recharging the battery.

Abstract: A conveyor belt roller guard comprises opposite first and second longitudinal side panels, opposite transverse side panels, and a bottom panel. The first and second longitudinal side panels, the transverse side panels, and the bottom panel are arranged in a manner adapted to define a u-shaped trough that comprises a cavity that is open from above. The first longitudinal side panel has a lower portion that is hinged relative to the transverse side panels about a first pivot axis in a manner such that the first longitudinal side panel can be swung downward while the bottom panel and the transverse side panels remain stationary. The first pivot axis extends substantially horizontal and parallel to the first longitudinal side panel.
