Patent number: 11559864Abstract: A tool changer device for a robotic arm comprising a robot adapter (1) particularly adapted to be connected to a robotic arm (5) and to a tool (6). The robot adapter (1) comprises a pneumatic cylinder (117) inside which a piston (116) is slidably arranged for activating a coupling and uncoupling mechanism (120) of the robotic arm (5) to the tool (6). On one of the walls of the robot adapter (1) at least four through conduits (24, 25, 26, 27) are arranged, one end of which opens into the pneumatic cylinder (117) and another end of which opens outside of the pneumatic cylinder (117). The device further comprises a first differential pressure sensor (18) connected to at least two of the through conduits (24, 25), and a second differential pressure sensor (19) connected to another two of the through conduits (26, 27).Type: GrantFiled: June 18, 2019Date of Patent: January 24, 2023Assignee: EFFECTO GROUP S.P.A.Inventors: Giovanni Patrini, Stefan Casey

Patent number: 11537273Abstract: An online system presents a content item to users and receives selections of reaction icons from the users. The online system generates a background animation with the selected reaction icons and a foreground animation to be layered on top of the background animation. The online system sends the background and foreground animations to a client device to be cached. Further, the online system presents the content item to a viewing user associated with the client device and receives a selection of a reaction icon from the viewing user. The online system selects a subset of the users based on the viewing user's affinity to the users, retrieves images of the selected users, and send the images to the client device. The client device customizes the background and foreground animations based on the images and the viewing user's reaction icon to generate a compound animation for display to the viewing user.Type: GrantFiled: December 7, 2020Date of Patent: December 27, 2022Assignee: Meta Platforms, Inc.Inventors: Robert Benson Walton, Zachary W. Stubenvoll, Julia Harter Toffey, Skyler Bock, Silvia Chyou, Jordan Richard Honnette, Wei-Sheng Su, Jerod Wanner, Stefan Casey Parker, Renyu Liu, Rajat Bhardwaj

Patent number: 10399234Abstract: A handwheel assembly includes a housing. A shaft having a central axis is rotatably supported by the housing. A locking device is rigidly attached to the housing. A rotary gear is circumferentially disposed over the shaft. A handwheel is circumferentially disposed over the shaft. The rotary gear and handwheel are operable to slide along the shaft from a first locked position to a second unlocked position. In the first locked position, the rotary gear is engaged with the locking device to rotationally lock the shaft. In the second unlocked position, the rotary gear is disengaged from the locking device to allow the shaft to rotate.Type: GrantFiled: September 11, 2017Date of Patent: September 3, 2019Assignee: Applied Robotics, Inc.Inventors: Timothy M. Strang, Stefan Casey

Patent number: 8003954Abstract: An ion source has an arc chamber with an electron-emitting element and a repeller. A manifold assembly defines a cavity and a gas outlet configured to allow gas flow to the arc chamber. This gas outlet is closer to the repeller than the electron-emitting element. In one embodiment, the ion source has a first crucible and a second crucible. The first crucible and the second crucible are connected to the manifold assembly. In one instance, the crucibles have tamper-resistant features.Type: GrantFiled: December 19, 2008Date of Patent: August 23, 2011Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: John Slocum, Kevin M. Keen, Chris Campbell, Robert Lindberg, Stefan Casey
