Patent number: 12071788Abstract: 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 retain position to permit removal.Type: GrantFiled: April 28, 2022Date of Patent: August 27, 2024Assignee: dormakaba USA Inc.Inventors: Brendon Allen, John Andrew Snodgrass, Street Anthony Barnett, III, Michael Hans Viklund

Publication number: 20240225775Abstract: 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.Type: ApplicationFiled: February 25, 2022Publication date: July 11, 2024Applicant: Stryker European Operations LimitedInventors: James G. Walen, Rahul Eapen, Clifford Edwin Lambarth, Caleb Gossens, Fadi Ghanam, Michael Laubenthal, John Andrew Snodgrass

Patent number: 11920378Abstract: 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.Type: GrantFiled: April 4, 2020Date of Patent: March 5, 2024Assignee: dormakaba USA, IncInventors: Street Anthony Barnett, III, Brendon Allen, John Andrew Snodgrass, Shaine Strullmyer
