  • Patent number: 12637304
    Abstract: Systems and methods are disclosed for active and passive electromagnetic switching for sortation shuttles along a track. An example system for active and passive electromagnetic switching for sortation shuttles may include a track having a first linear path and a first curved path that intersects the first linear path. The system may include a shuttle with a first ferrous block, the shuttle configured to move along the track, a first set of electromagnets disposed along a side of the first curved path, and a first set of permanent magnets disposed along a side of the first linear path. Energizing the first set of electromagnets causes the shuttle to merge onto the first curved path via interaction with the first ferrous block.

  • Patent number: 12419659
    Abstract: A surgical device comprising: (a) a first jaw; (b) a second jaw opposing the first jaw, the first jaw, the second jaw, or both being movable relative to one another between a jaw nominal position and a jaw clamped position; (c) a clamp lever in communication with the first jaw and the second jaw, the clamp lever moving the first jaw, the second jaw, or both from the jaw nominal position to the jaw clamped position when an external force is imparted upon the clamp lever in a first direction; and (d) a stop bias member that stops movement of the clamp lever when the external force is removed so that the first jaw and the second jaw are in the jaw nominal position at rest; wherein the first jaw and the second jaw are movable from the jaw nominal position to a jaw spread position when the clamp lever is moved in a second direction that opposes the first direction by an external force deforming the stop bias member so that a distance between the first jaw and the second jaw is larger in the jaw spread position tha
