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 ranging and tracking system and method employs a Coherent Array Reconciliation Tomography (CART) approach that benefits from a series of samples gathered from deployed receivers in an area of interest, and applies a sequence of matrix operations and transformations to data defining locations in a Cartesian grid space for summing constructive characteristics in a received waveform for identifying a leading edge indicative of a time of arrival (TOA) from a signal source, and computing a metric based on the distance to the signal source. Sampled waveform information (data) from multiple locations in the area of interest allows computation of a likelihood metric for each location in the grid space of containing the signal source. Rendering of the grid space location having the highest likelihood metric illustrates a position of the signal source, and may be graphically depicted clustering of the locations depicting a high likelihood.

Abstract: The iron and steel industry has a history of environmental consciousness, and efforts are continually made to reduce energy consumption and CO2 emissions. However, the carbothermic process has approached limits on the further reduction of greenhouse gas emissions, and only marginal improvements can be expected. Low temperature electrolysis using a dispersion medium to efficiently distribute charge throughout a colloid mixture including iron oxide provides an environmentally friendly method for performing an electrochemical reduction of Fe2O3 to produce granular Fe. An electrical-ionic conductive colloidal electrode containing the electrochemically active species (Fe2O3 particles), the liquid electrolyte (NaOH solution), and a percolating electrical conductor (carbon network) is utilized to produce Fe. The resulting simultaneous percolation of electrons and ions effectively increases the area of the current collector, and enables the process to function at higher currents and rate of charge transfer than static electrolysis.

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.
