Abstract: Embodiments of the innovation relate to a mixed reality device having a mixed reality display and a controller disposed in electrical communication with the mixed reality display. The controller configured to receive topology data associated with a network and three-dimensional (3D) embedded network data associated with the network. The controller is configured to construct a hierarchical data structure from the topology data and the 3D embedded network data. The controller is also configured to display a level of the hierarchical data structure as a virtual object in a 3D space on the mixed reality display, the level of the hierarchical data structure identifying a subset of nodes and a subset of edges of the hierarchical data structure.

Abstract: An articulating, steerable surgical probe includes an elongated, flexible transfer tube adapted for insertion into a surgical region for endoscopic laryngeal laser surgery. A lumen is defined by an interior of the transfer tube, and a laser fiber extends through the lumen for delivering a therapeutic laser signal to a distal end of the laser fiber. An articulating tip at the distal end of the transfer tube is responsive to articulating forces from a retractable tether for directing the treatment probe in a direction of the articulation, and a linkage to the tether from a control module effects controlled retraction of the tether for articulating the tip towards a surgical target, such that the articulating tip imposing a bend radius based on a signal loss through the laser fiber.

Abstract: A rechargeable lithium-ion (Li-ion) battery employs a low temperature approach to battery manufacturing that forms charge material from kinetic energy of high velocity particles impelled into an aggregation such that bombardment of the particles against other particles in the aggregation forms a charge conveying structure. High velocity bombardment from a carrier gas nozzle accumulates an active charge material in a layered arrangement for the finished battery. Preparation of the particles, such as by ball milling or spraydrying, arranges particle agglomerations. The particle agglomerations, when impelled against other agglomerations or a current collector, forms a layer of cathodic, anodic or electrolytic battery material. The metallic binder conveys charge for mitigating or eliminating a need for a planar current collector underlying the sprayed layer. The resulting layers are suitable for battery operation, and are manufactured in an absence of any solvent drying or disposal.

Abstract: A force absorbing device for a footwear appliance includes a shoe sole having a planar sole surface, such that the shoe sole is adapted to be disposed against a ground surface such as turf, grass or dirt. A ground interface member having a general appearance of a footwear cleat extends from the planar sole surface. Within the sole, the ground interface member couples to a force mitigation assembly for absorbing forces against the cleat. The force mitigation assembly includes an elastic field of a resilient, compressible material, and an inclined surface is disposed against the elastic field and oriented to compress the elastic field. A linkage or connecting surface transmits a displacement force for disposing the inclined surface across the elastic field, where the inclined surface compresses the elastic field as it moves across. In response, the elastic field exerts a counterforce against the ground interface member.

Abstract: Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.

Abstract: A surgical head clamp and robotics platform secures a head of a patient and positions an instrument relative to the head for a medical procedure. The head clamp and robotics platform comprises a planar C-shaped frame for at least partially encircling the head of a patient. An instrument arm is mounted is to a free distal end of one arm member of the frame. The instrument arm extends away from the min member in a direction transverse to the plane of the frame. The instrument arm includes a base mounted to the arm member for movement along three degrees of freedom relative to the frame, a proximal portion extending from and pivotally connected to the base, and a distal instrument holder extending from and pivotally connected to the proximal portion. The instrument arm functions to selectively position the instrument in an angular position relative to the head clamp.

Abstract: Extraction of rare earths from end-of-use machinery having rare earth magnets provides a closed-loop process towards recycling rare earths from commingled devices having embedded magnets such as motors, generators and disk drives. A low temperature process selectively leaches the magnet material from mixed scrap containing shredded fragments of the machinery which includes other metals such as steel and copper. Filtration separates the other metals from the leached, dissolved magnet material, which is precipitated by oxalic acid to form oxalates in powder form, suitable for use in production of new rare earth magnetic material. Leaching acid, such as HCl (hydrochloric acid), is recoverable via pyrohydrolysis, and redirected back to the leaching step for completing the closed-loop aspect.
