A high capacity micro fuel cell system for supplying power to a portable device. In the transmission of information, a data transmission protocol is used, wherein in the method one or more protocol conversions are conducted in the protocol stack for the information to be transmitted, said protocol stack comprising at least an application layer and a physical layer. A common process window can also be used to provide objective information regarding defect printability. Alternately, a configuration utility enables a user to select the antenna type for the access point when it is installed in the field. The method of sensing facial gestures includes determining a basic database for sensing facial gestures of a user, estimating a head pose of the user, extracting a mesh model corresponding to the estimated head pose using at least one of a personalized DB and a general DB, and sensing the facial gestures using the extracted mesh model, and reflecting the sensed facial gestures to a virtual object.
