    Abstract: Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Mn (manganese), Li (lithium), and Fe (iron) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel 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: An edge sharpness measurement apparatus includes a clamp for securing a test medium against a frictional member, and an engagement mechanism for a normal force, such that the normal force directs the test medium against the frictional member with a force based on operational conditions of the test medium. A further engagement mechanism is for a tangential force, in which the engagement mechanism is adapted to increase the tangential force to identify a tangential force sufficient to dispose the frictional member across the test medium. A pivot defines an angle of application of the tangential force relative to the normal force, such that disposing the frictional member across the test medium defines a point of overcoming frictional forces between the test medium and the frictional member. A measurement device, such as a gauge or range on a spring, measures the tangential force sufficient to dispose the frictional member.

    Abstract: Embodiments of the innovation relate to, in an access controller, a method for providing access to a network resource. The method includes receiving, by the access controller, a network access request and user interaction information associated with the network access request from the client device, the user access information received with the network access request from the client device. The method includes comparing, by the access controller, the user interaction information with a policy corresponding to the user interaction information. The method includes providing communication, by the access controller, between the client device and the network resource associated with the network access request in response to detecting an association between the user interaction information and the policy.

    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.

    Abstract: A system and method for synchronizing the phases and frequencies of devices in multi-user, wireless communications systems are provided. A primary beacon signal is transmitted by a destination node in a wireless communications network to a plurality of source nodes. Secondary beacon signals are also exchanged between the source nodes. Using the primary and secondary beacon signals, the nodes generate local phase and frequency estimates which are used to control local phases and frequencies of the source nodes. The source nodes then transmit common information to the destination at carrier frequencies based on the estimated local frequencies and phases, so that the phases and frequencies of the transmitted information are synchronized to facilitate coherent combining of the bandpass signals at the destination. Phase and frequency synchronization can be applied to wireless communications systems having any number of source nodes, and effects of Doppler shifts and moving platforms are accounted for. Acoustic and radio-frequency signaling can be utilized.
