Abstract: A mandrel assembly may be used with a rotary power tool to provide a reliable and stable connection between the rotary tool and a tool accessory. The mandrel assembly provides a quick-connect/quick-release connection between the tool output shaft and the accessory via a clamping action. In particular, the mandrel assembly is movable between a first configuration in which the accessory may clamped tween a clamping element formed on one end of the mandrel and a collar which surrounds the mandrel and a second configuration in which the accessory may be loaded onto or detached from the mandrel assembly. Movement from the first configuration to the second configuration, and from the second configuration to the first configuration each include axial motion in combination with a rotation of the mandrel in the same direction relative to the collar.

Abstract: Techniques and systems are provided for positioning mixed-reality devices within mixed-reality environments. The devices, which are configured to perform inside out tracking, transition between position tracking states in mixed-reality environments and utilize positional information from other inside out tracking devices that share the mixed-reality environments to identify/update positioning of the devices when they become disoriented within the environments and without requiring an extensive or full scan and comparison/matching of feature points that are detectable by the devices with mapped feature points of the maps associated with the mixed-reality environments. Such techniques can conserve processing and power consumption that would be required when performing a full or extensive scan and comparison of matching feature points. Such techniques can also enhance the accuracy and speed of positioning mixed-reality devices.

Abstract: A transcatheter delivery device including a catheter and at least one stabilizer useful for transseptal procedures. The stabilizer includes a shaft connected to an anchor. The anchor has a delivery position in which the anchor is collapsed against the shaft and a deployed position in which the anchor expands to engage a pulmonary vein or atrial appendage to support the catheter within the septal wall as the catheter moves within a left atrium. Various disclosed delivery devices are also configured to ablate tissue proximate the anchor and/or can be disconnected from the delivery device after the procedure to occlude an atrial appendage. Methods of using the disclosed delivery devices and treating a heart are also disclosed.

Abstract: A system receives input from a user to initiate a process of generating a holodouble of the user. The system obtains image data of the user and deconstructs the image data to obtain a set of sparse data that identifies one or more attributes associated with the image data the user. The system uses a holodouble training model to generate and train the holodouble of the user based on the set of sparse data and obtained image data. The system renders a representation of the holodouble to the user concurrently while capturing new image data of the user, receives input from the user comprising approval of the holodouble, and completes training of the holodouble by saving the holodouble for subsequent use. The subsequent use includes one or more remote visual communication sessions.

Abstract: Systems and methods are provided for generating, selecting, modifying and/or otherwise configuring occluder(s) used in mixed-reality environments. Pose information of a trackable device worn or carried by a user is determined. Based on that pose information, an assumption regarding the user's own pose is determined. An occluder is then configured in a manner to correspond to the assumed pose of the user for use in the mixed-reality environment. By generating the occluder in this manner, improved battery life by the trackable device can be achieved relative to conventional systems that rely entirely on iterative scanning of the user's body to determine body position.
