Adders each add up an addition value sent from a metric calculator and a state metric read from a memory. A housing member is connected between the main body and the upper cover. The background task is always active and functions to respond to an incoming call even if the user is in a graphical user interface window that requires some input from the user. The actuator members include cooperating detents that selectively release the actuator members as the carrier assembly reaches predetermined positions along the sheath for deploying the clip from the carrier assembly, and that collapse the splines to allow removal of the apparatus after deploying the clip.
