Abstract: A force dissipating device in a footwear appliance includes an actuator responsive to a displacement force from a shoe sole surface, and an elastic field of resilient, compressible material. The elastic field is elongated in a direction aligned with the displacement force, and an inclined surface is attached to the actuator and disposed against the elastic field. The actuator is adapted for movement parallel to the elastic field, while the inclined surface is oriented to compress the elastic field in a direction defined by the inclined surface. The inclined surface is oriented at an angle to compress the elastic field in a direction substantially perpendicular to vertical actuator displacement, thus providing a constant region of opposed, compressive force that is generally constant, rather than increasing with displacement distance.

Abstract: A mixed reality device includes a mixed reality display and a controller disposed in electrical communication with the mixed reality display. The controller is configured to display a hierarchical data structure as a virtual object in a 3D space on the mixed reality display, the hierarchical data structure constructed from topology data associated with a network and three-dimensional (3D) embedded network data associated with the network; receive a hierarchy traversal command relative to at least one node of a first level of the hierarchical data structure; and, in response to receiving the hierarchy traversal command, display at least one node of the second level of the hierarchical data structure on the mixed reality display.

Abstract: A power point tracking apparatus employs irradiance detection for performing Maximum Power Point Tracking (MPPT) of a PV panel. The apparatus controls an operating voltage of a PV panel inverter by regulating the operating voltage of the inverter at a computed optimal voltage based on a detected irradiance of light on the solar panel providing power to the inverter to result in a maximum power generation from the solar panel. The inverter receives the DC (direct current) from the solar panel and generates an AC (alternating current) signal at a fixed voltage (typically 110-120 v) usable by grid based power consumers.

Abstract: Actuators and methods of use are provided. An actuator may include an inner member made from an elastic material and defining a compartment for receiving an actuating fluid, the inner member being moveable in a longitudinal direction from a relaxed state to an expanded state by introducing an actuating fluid into the inner member; and an outer member made from an inelastic material and being disposed around the elastic inner member to control expansion of the elastic inner member in a radial direction, the outer member being moveable from a folded relaxed configuration to an unfolded extended configuration as the inner member moves from the relaxed state to the expanded state, wherein the movement of the actuator between the relaxed state and the expanded state causes a movement of a structure to which the actuator is attached.

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: A service provider device includes a controller having a memory and a processor. The controller is configured to receive a device access request from the client device via a residential network, the server provider device being located external to the residential network and detect a communication type identifier associated with the device access request. The controller is configured to establish a secure communication channel between the client device and a middlebox associated with the detected communication type identifier and provide communication between the client device and the server device via the secure communication channel between the client device.

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: Recovery of scandium from mined red mud includes adding an acid to a quantity of red mud for converting oxides in the red mud, and roasting the quantity of red mud for decomposing compounds having low thermal stability, typically iron and titanium. Water is added to the roasted red mud for leaching the converted oxides into a leach liquor mixture including scandium and other dissolved rare earths, and the leach liquor mixture is agitated by sonication or ball milling to increase an exposed surface area of red mud particles in the leach liquor. PH of the leach liquor is adjusted to precipitate the rare earths while leaving the scandium in solution in the leach liquor, followed by precipitating the separated scandium oxalate remaining in the leach liquor by reducing the pH and adding oxalic acid. Precipitated scandium oxalate may then be filtered from the leach liquor.

Abstract: An assessment engine includes a definition of inquiry skills being assessed. Assessment models are used to infer skill demonstration as one or more students engage in inquiry within computerized simulations and/or microworlds. A pedagogical agent and/or help system provides real-time feedback to one or more students based on the assessment model outputs, and/or based on additional models that track one or more students developing proficiency across inquiry tasks over time. A pedagogical agent and/or help system for science inquiry tutoring responds in real-time on the basis of knowledge-engineered and data-mined assessment and/or tracking models.
