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 valuable charge materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. However, LiFePO4 is a waste stream charge material often discarded due to infeasibility of recycling. LiFePO4 is precipitated as FePO4 and remains as a by-product, along with graphite and carbon, which are not dissolved into the solution. FePO4 can be separated from graphite and carbon, FePO4 can be used to synthesize LiFePO4 as cathode materials and graphite can be regenerated as anode materials.

Abstract: A field of vision assessment is performed by reported positional feedback of visual markers at an outer circumference of a subject's field of vision. An array of visual markers arranged in a grid is rendered near a peripheral vision limit of the subject. The visual markers are disposed at known locations relative to an origin of the field of vision of the subject. Based on reported visual markers, a mapping of the visual markers to the location denotes a point on a periphery of limit of the visual field. The mapped points define vertices of a polyhedron having edges denoted by the vertices and the origin. The volume of the resulting polyhedron correlates to the field of vision of the subject, since as the periphery of the field of vision increases, the computed volume also increases.

Abstract: Embodiments of the innovation relate to a persona development device comprising a controller having a memory and a processor. The controller is configured to receive a research request from a user interaction device, the research request including an attribute related to a persona. The controller is configured to, in response to identifying a correspondence between the attribute of the research request and a persona of a persona database, forward a request response including the persona to the user interaction device. The controller is configured to, in response to identifying a lack of correspondence between the attribute of the research request and a persona of a persona database, retrieve user data from a user data source, create a persona prototype based upon the user data and corresponding to the attribute of the research request, and forward a request response including the persona prototype to the user interaction device.

Abstract: In a text simplification system, a method for replacing text in a field of view of a user, comprises receiving eye movement data from an eye-tracking device, the eye movement data relating to text provided in a field of view of a user and detecting a cognitive load associated with the eye movement and corresponding to a visual location of the field of view of the user. The method comprises, when the cognitive load meets a cognitive load threshold, identifying visualized text provided in the visual location of the field of view of the user and identifying personalization information associated with the user. The method comprises, when the personalization information meets a personalization information criterion, replacing the visualized text provided in the visual location of the field of view of the user with simplified text.

Abstract: A robotic configuration employs a system of low-cost, relatively lightweight beams and linkages fabricated from a planer material from a series of cuts and folds. The beams are folded along crease lines to form a 3-dimensional structure from a 2-dimensional substrate such as a polyester or other semi-rigid sheet. Tabs and appendages, or keys, cut into the planar material engage slots or apertures cut into adjacent members to define linkages. The linkages include tabs that are insertable in a one-way manner, such that removal is prevented but articulate and rotational movement is permitted by the resilient and flexible nature of the planar sheet material. An arrangement of beams and linkages are cut and formed based on a pattern imposed on a single planar sheet. The beam and linkage arrangement defines a robotic configuration for transport and other actions from an actuation source such as a motor.

Abstract: A recommendation for purchase or selection of a package of food to a consumer, such as a retail of wholesale purchaser of the food package, or a direct or indirect consumer of the food contained in the food package is generated by selecting at least one nutritional value from a food package label by optical character recognition of a representation of the selected nutritional value as it is presented on the package of food. The at least one selected nutritional value is compared to at least one recommended nutritional value corresponding to the selected nutritional value to form at least one comparison value. The comparison value is employed to generate a recommendation that is displayed to the consumer, such as by superimposing the recommendation over an image on a display screen of the food package label as an augmented reality, or in real time, meaning that the recommendation appears simultaneously with the optical character recognition of the nutritional value, wherein the recommendation is displayed with, or is superimposed on an image on the display screen of the representation of the nutritional value, thereby making a recommendation of the food package to the consumer.

Abstract: A superhydrophobic surface is formed by growing a plurality of etchable, sacrificial structures, and depositing a discontinuous hydrophobic material onto the sacrificial structures. The discontinuity facilitates etching of the sacrificial structures to remove the grown structures while leaving the deposited material intact to result in surface features for achieving superior hydrophobic properties.

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.
