Abstract: A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly and an end effector. The body assembly includes a trigger and a casing configured to couple with the transmission assembly. An information transmission system transmits instrument information received from a sensor, for example, to a secure server via a secure gateway connected to the instrument. The instrument may be previously tested on a calibration kit to pre-determine and load surgeon-specific settings onto the instrument prior to use.

Abstract: Gaze enrollment, including displaying an enrollment progress user indicator, animating movement of user interface elements, changing the appearances of user interface elements, and/or moving a user interface element over time, enable a computer system to more accurately track the gaze of a user of the computer system.

Abstract: A telephone call screening system screens telephone calls placed to a subscriber based upon a preferred caller database established by the subscriber from a networked caller registry database. A caller registration system allows callers to select a private identifier unique to the caller and registers the callers in a caller registry database. The subscriber establishes the preferred caller database by connecting to the caller registration system and selecting the preferred callers. The private identifiers associated with the selected preferred callers are then stored in the preferred caller database. When a caller calls the subscriber, the caller is asked to enter the caller's private identifier. A caller disposition process is initiated based on whether the private identifier is in the preferred caller database.
