The present invention is related to the realization of a simplified bottom electrode stack for ferroelectric memory cells. The controller piece includes a main processor and one or more buttons in communication with the main processor. An in-plane rotation of the MEMS sensor may be sensed with the first out-of-plane electrode pair and the second out-of-plane electrode. The first end of the breakaway member is disposed in the first mast piece, the second end of the breakaway member is disposed in the second mast piece, and the breakaway section is located between the first and second mast pieces. A scavenger column and a header operate independently to collect and remove air before it can accumulate in the tower header and interfere with the siphon process. When a printing processing portion of a first managing server or a second managing server receives a print command from a user’s mobile phone, the URL indicating the storage location of the image data as well as the printing conditions are sent to a printing server, the printing server and the user are connected, and the printing related processes are performed by the printing server.
