Abstract: Surgical systems and methods involving a reamer tool and a surgical robotic arm. The reamer tool has a shaft, a tool engagement surface coupled to the shaft, and a reamer head attached to the shaft. The surgical robotic arm supports a guide that can receive the reamer tool. The guide has a pair of arms, each arm extending to an arm end and the arm ends being spaced apart from one another to provide an opening between the arm ends. A channel is formed between the arms. The guide enables a portion of the shaft to move through the opening between the arm ends such that the shaft portion can enter and exit the channel. The arms define a guide engagement surface that is arc-shaped and that enables contact with the tool engagement surface to facilitate alignment of the reamer tool and the guide.

Abstract: Surgical systems and methods involve a robotic arm with a first mounting portion that releasably receives a sterile barrier assembly and a second mounting portion associated with a surgical component. An illumination device is coupled to the robotic arm. Controller(s) detect, using one or more sensors, a condition associated with installation of one or more of the sterile barrier assembly and the second mounting portion to the first mounting portion. The controller(s) control the illumination device to indicate the condition to a user.

Abstract: An assembly for a surgical arm includes a tool to position a prosthesis and an end effector. The tool has a tool shaft extending along a tool axis and a tool engagement surface. The end effector has a mount attachable to the surgical arm, a body portion extending from the mount, a distal end, and a guide portion is at the distal end of the body portion to receive the tool. The guide portion has a pair of arms, each arm extending to an arm end and the arm ends are spaced apart from one another to provide an opening between the arm ends. A channel is formed between the arms and extends along a guide axis. The arms define an arc-shaped guide engagement surface to enable contact with the tool engagement surface for facilitating alignment of the tool axis and the guide axis.

Abstract: A robotic surgical system includes a robotic arm comprising a plurality of links and joints, an end effector, and a mounting assembly for coupling the end effector and the robotic arm. The mounting assembly includes a robot mount associated with the robotic arm and an end effector mount associated with the end effector. The mounting assembly also includes a sterile barrier assembly including a coupling and kinematic couplers. A first lock assembly releasably secures the coupling to the robot mount and a second lock assembly releasably secures the end effector mount to the coupling. A tensioner associated with either mount is movable between a first position and a second position such that the kinematic couplers engage with, and provide a kinematic coupling between, the mounts through the sterile barrier assembly to constrain six degrees of freedom of movement between the mounts.

Abstract: Exemplary methods and systems provide for production of geographically located, accurate indoor maps of physical spaces and provide navigation guidance for users in physical spaces, and process requests for users related to available physical space within said physical spaces. Aggregated information about the physical spaces is curated and converted using automated procedures into a data model that contains all elements of said physical spaces, including geographic data about the physical space's location on the globe. The system and computer program embodiments retrieve the converted data, load it on mobile devices or computers, rendering it on these devices in the correct global geographic context, allowing users to interact with the data to select rooms, and send and receive requests to and from external systems regarding these selections. Users navigate within the physical spaces using mobile devices and the computer program embodiments in tandem to provide accurate directions and guidance.

Abstract: A mobius zipper learning model is described. The learning model can include a device comprising two 3D printed, hard plastic, semi-circular halves connected by a plastic zipper, which could also be 3D printed, with top ends connected to the frame halves. The zipper can be twisted and then reconnected at the bottom of the frames using embedded fasteners (e.g., hook and eyelet, snaps, or hook and loop). The Mobius zipper permits topologists and others to explore and demonstrate Mobius properties without having to seek and size workable material (usually paper) and/or successfully slice the selected material. Further, use of the Mobius Zipper results in no waste of material.

Processing circuitry is provided to determine from the force measurement data when an end of injection has been reached, the end of injection corresponding to the plunger rod having reached an end position in a distal portion of the barrel of the syringe during administration of the injection by the user. Machine readable instructions and an injection monitoring method are also provided.

Abstract: A network of motion sensors employs sensitive accelerometers to issue time-domain measurements of building movement from multiple locations within and between buildings and other structures. The time-domain measurements from the various motion sensors are synchronized and converted into frequency-domain measurements of building movement. Individual motion sensors can be equipped with the requisite processor and memory to synchronize and covert the time-domain measurements. The motions sensors can classify detected events into various event types, such as earthquakes, wind events, or bipedal locomotion. The sensors can also communicate with one another or other resources to calculate event probabilities. A motion sensor may, for example, receive an earthquake-verification signal responsive to an earthquake-verification request. The network of motion sensors can calculate local soil stiffness and financial loss estimations responsive to their individual or collective frequency-domain measurements.
