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: 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: Methods and systems for observing/analyzing interactive behavior are presented. In one instance, the method for observing/analyzing interactive behavior includes interacting, using a robot, with a subject and obtaining data from interaction between the subject and the robot, the data from the data acquisition components, the data being used for diagnosis and/or charting progress. In one instance, the robot includes data acquisition components, interaction inducing components (such as, but not limited to, movable eyelids, movable appendages, sound generating components), a control component operatively connected to the interaction inducing components and a processing component operatively connected to the control component and the data acquisition components, the processing component being configured to obtain data from the data acquisition components, the data being used for diagnosis and/or charting progress. In one instance, the robot is integrated with a computer-aided system for diagnosis, monitoring, and therapy.

Abstract: Drying a planar substrate such as paper sheet goods for packing materials includes layering a phase change material (PCM) on a substrate, in which the substrate has a moisture content and adapted for moisture removal to form a planar medium. A drying process disposes the substrate adjacent to a plurality of rollers and heat the layered substrate to a predetermined temperature based on a specific heat of the PCM. The rollers advance the layered substrate in series through pocket ventilation regions between the heat transfer elements, such that the pocket ventilation regions permit drying of the substrate enhanced by the specific heat of the temperature sensitive material. Upon drying, the layered substrate forms the planar medium suitable for use as a packing medium or other suitable application. The pocket ventilation regions are based on the PCM to facilitate drying and eradication of moisture from the paper planar substrate.

Abstract: In a mobile sensing device, a method of detecting blood alcohol content includes receiving time-series gait data from at least one sensor of the mobile sensing device as a user walks and detecting a set of attributes associated with the time-series gait data, each attribute of the set of attributes related to the user's gait. The method includes comparing the set of attributes with a machine learning classification model learned from a training data set of attributes to determine at least one of a blood alcohol content range of the user and an impairment level of the user and outputting a notification associated with the at least one of the blood alcohol content range of the user and the impairment level of the user.

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: An indoor localization system uses Visual Simultaneous Localization and Mapping (VSLAM) aided by gyroscope sensor information. Indoor environments pose several challenges which could cause a vision only system to fail due to tracking errors. Investigation revealed significant feature loss in a vision only system when traversing plain walls, windows and staircases. However, the addition of a gyroscope helps in handling such difficult conditions by providing additional rotational information. A portable system consisting of an Inertial Measurement Unit (IMU) and a stereo camera has been developed for indoor mapping. The images and gyroscope rates acquired by the system are stored and post-processed using Gyroscope Assisted Scalable Visual Simultaneous Localization and Mapping Algorithm.
