Verification of device user identity can be used to enable or disable the display of secure information. Identity verification can also be included within information that is transmitted from the device in order to determine appropriate security measures by remote processing units. The apparatus may be incorporated within wearable computing that performs other functions including vision correction, head-mounted display, viewing the surrounding environment using scene camera(s), recording audio data via a microphone, and/or other sensing equipment.

Ejecting assembly for a surgical stapler

An end effector includes first and second jaws, a drive screw, a lead screw nut, and a drive beam. The drive screw is disposed within the first jaw. The lead screw nut defines a threaded bore that receives the drive screw. The lead screw nut is advanced along the drive screw as the drive screw is rotated in a first direction and is retracted along the drive screw as the drive screw rotates in a second direction. The drive beam is releasably coupled to the lead screw nut when the lead screw nut is in a retracted position. As the lead screw nut is advanced the drive beam is pulled by the lead screw nut. The drive beam is decoupled from the lead screw nut as the lead screw nut is advanced such that the lead screw nut is advanced relative to the drive beam.
