An exemplary method for selecting one of a plurality of systems on a multi-mode device capable of communicating on a first air interface technology and a second air interface technology is disclosed. A graphical program is received, where the GP specifies performance criteria. When the ink container is mounted, a user moves the ink container so that a first inclined portion first contacts the sliding projection and thereafter the ink contained is moved in an obliquely below direction toward the head cartridge while sliding the sliding projection along the first inclined portion. Further, using the plurality of pressure inputs may detect a velocity of usage of the stylus device. In this way, a perceptible reduction is achieved in the weight of a piston in relation to conventionally manufactured forging pistons.
