  • Publication number: 20240130825
    Abstract: An adapter for removably coupling a tracker to a surgical handpiece includes a proximal member having an interface configured to engage and prevent rotation of the proximal member relative to the surgical handpiece, a distal member slidably and rotatably coupled to the proximal member, a biasing member disposed between the proximal distal members and configured to urge the proximal and distal members in opposing directions, and a tracking array mount coupled to the distal member. The biasing member is configured to be compressed by a reference feature of the end effector and the surgical handpiece when the distal member is disposed on the end effector and the end effector is coupled to the surgical handpiece, the compressed biasing member creating a frictional force between the distal and proximal members that resists rotation of the distal member relative to the proximal member.

  • Patent number: 11952801
    Abstract: A removable lock core for use with a lock device having a locked state and an unlocked state is disclosed. The removeable lock core may include a cam member tailpiece which is moveable between a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which permits removal of the removeable lock core from the lock device which corresponds to the lock device being in the unlocked state. The removeable lock core may include an electro-mechanical drive assembly which in a disengaged state is decoupled from the cam member tailpiece and in an engaged state is coupled to the cam member tailpiece. A cam lock having a locked state and an unlocked state for use with a catch is disclosed.

  • Patent number: 11920378
    Abstract: The present disclosure generally relates to a lock including a blocker (e.g., a bolt) useable to selectively prevent access through a portal such as a door. The blocker can be retained in a blocking position to prevent access through the portal by a retainer. In alternative embodiments, the blocker can also be retained in an open position to allow access through the portal. A retainer can be utilized to retain the blocker in the blocking position preventing access through the portal and can also be utilized, in certain embodiments, to retain the blocker in the open position to allow access through the portal. A retainer blocker can be utilized to maintain the retainer in position to retain the blocker (e.g., bolt) in a fixed position. An actuator may, in certain alternative embodiments, be employed to position the retainer blocker. In certain embodiments, the actuator is controlled by an electronic controller.

  • Patent number: 11913254
    Abstract: An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to the envelope of the lock core body to permit removal.

  • Publication number: 20220160372
    Abstract: A surgical footswitch for controlling a surgical instrument. The surgical footswitch includes a base. A treadle is rotatably coupled to the base to operate the surgical instrument. A foot guard is also rotatably coupled to the base. A blocking portion of the foot guard is configured to prevent physical access to the treadle in a lateral direction in a first position and permit access to the treadle in a lateral direction in a second position. A floor engagement portion of the foot guard engages a floor surface when the blocking portion is in the first position. The floor engagement portion is spaced from the floor surface when the blocking portion is in the second position. The floor engagement portion permits physical access to the treadle in a longitudinal direction when the blocking portion is in both the first position and the second position.
