Abstract

See full text

An electronic cigarette with an atomizer cartridge and a battery assembly. The atomizer cartridge has an atomizer coupled to a first and second terminal of a cartridge interface. A passive electrical circuit is coupled between the first terminal and a sensing terminal. The battery assembly has an interface with a first, second, and sensing contact. The interface engages the cartridge interface to provide electrical continuity between the terminals and contacts. The battery assembly has an atomizer drive circuit connected between the first and second contact, and a controller that activates the atomizer drive circuit in response to negative pressure at a draw sensor. A sensing circuit coupled to the sensing contact outputs a parameter signal indicative of the electrical parameters of the passive electrical circuit. The controller activates an RGB LED to produce discrete colors of light corresponding to discrete values of the parameter signal.
