Abstract: An exemplary latchbolt assembly includes a latchbolt, a locking sleeve, and a roller engaged between the latchbolt and the locking sleeve. The latchbolt is configured to drive the roller from a first position to a second position as the latchbolt moves from a projected position to a depressed position. The locking sleeve includes a blocking surface and a recessed portion. When the blocking surface is aligned with the roller, the locking sleeve retains the roller in the first position, thereby retaining the latchbolt in the projected position. When the recessed portion is aligned with the roller, the locking sleeve permits movement of the roller from the first position to the second position, thereby enabling depression of the latchbolt.

Abstract: A method for collaboration using digital notes. A facilitator starts a session during a video conferencing with participants and can share a screen with the participants. The screen displays a code, a session ID, and a link. Participants join the session by scanning the code with a camera, entering the session ID, or accessing the link. During the session, the participants can create digital notes or scan physical notes to have them converted to digital notes. The facilitator then receives the digital notes sent from the participants during the session and moves the digital notes to a group on the facilitator's screen. Since the facilitator's screen is shared with the participants, any participant can view the digital notes in the group from all of the participants for collaboration as controlled by the facilitator.
