Abstract: A robot control system determines which of a number of discretizations to use to generate discretized representations of robot swept volumes and to generate discretized representations of the environment in which the robot will operate. Obstacle voxels (or boxes) representing the environment and obstacles therein are streamed into the processor and stored in on-chip environment memory. At runtime, the robot control system may dynamically switch between multiple motion planning graphs stored in off-chip or on-chip memory. The dynamically switching between multiple motion planning graphs at runtime enables the robot to perform motion planning at a relatively low cost as characteristics of the robot itself change. Various aspects of such robot motion planning are implemented in particular systems and methods that facilitate motion planning of the robot for various environments and tasks.

Abstract: Systems and methods are described for establishing Proof of Location for a computing device (which may serve as Proof of Location for a user of the device). In some examples, establishing Proof of Location involves trackable features findable by the device at the location in question. In some examples, the computing device is configured to generate a point cloud of a trackable feature for comparison to a reference point cloud. Anti-spoofing methods are described for reducing the possibility of accidental or intentional false-positive Proof of Location results.

Abstract: Expandable fusion implants capable of being installed inside an intervertebral disc space to maintain disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. The expandable intervertebral implant may be configured to transition from a collapsed configuration having a first width and a first height to an expanded configuration having a second width and a second height. The implant may include front and rear plates each having horizontal ramps configured to interface with corresponding horizontal ramps on actuators and front ramps of left and/or right side portion assemblies.

Abstract: An implant assembly including an expandable vertebral body replacement implant. Two outer cores disposed on opposing ends of an inner are configured to move away from each other when the inner core is actuated. The implant assembly may include removable endplate configured to engage vertebral bodies as interbody spacer or through a corpectomy. The implant may include a locking mechanism to prevent collapse or movement the implant assembly after implantation. The locking mechanism may be automatically engage after removal of an inserter instrument from the implant assembly.

Abstract: A prosthetic implant for engagement between first and second vertebrae. The implant includes a first plate configured for attachment to the first vertebrae and defining a first interbody connection member and a second plate configured for attachment to the second vertebrae and defining a second interbody connection member. An interbody component includes a body with a first end defining a first plate connection member configured for connection to the first interbody connection member and a second end defining a second plate connection member configured for connection to the second interbody connection member. A method of inserting the implant is also provided.

Abstract: Embodiments herein are generally directed to vertebral implants and implant trials for use with vertebral implant assemblies. In some embodiments, these implants and implant trials may be used in conjunction with corpectomy procedures.

Abstract: A supervisory computer vision (CV) system may include a secondary CV system running in parallel with a native CV system on a mobile device. The secondary CV system is configured to run less frequently than the native CV system. CV algorithms are then run on these less-frequent sample images, generating information for localizing the device to a reference point cloud (e.g., provided over a network) and for transforming between a local point cloud of the native CV system and the reference point cloud. AR content may then be consistently positioned relative to the convergent CV system's coordinate space and visualized on a display of the mobile device. Various related algorithms facilitate the efficient operation of this system.

Abstract: An implant assembly including an expandable vertebral body replacement implant. The implant assembly includes a right hand end and a left hand end configured to attach to a threaded actuator. An outer ring is configured to surround each of the right and left hand ends and the threaded actuator. The implant assembly may include removable endplates configured to engage vertebral bodies as interbody spacer or through a corpectomy. The implant assembly includes a locking mechanism to prevent collapse or movement the implant assembly after implantation. The locking mechanism automatically engage after removal of an inserter instrument from the implant assembly.

Abstract: An implant assembly including a curved mesh cage and angled endplates. The implant assembly offers a safe and secure mesh cage while providing lordosis/kyphosis angling at the center of the construct instead of at the end of the cage only. One or more angled endplates may be included which allow the surgeon to make a construct unique to the patient's anatomy. The endplates press-fit into corresponding holes in the mesh cage for a secure fit.
