Abstract: A Ring-Arrayed Forward-viewing (RAF) ultrasound imaging and administration device combines an ultrasonic (US) US imager including a plurality of single element transducers arranged in a circular frame to define a ring array, and an instrument posture tracking circuit coupled to the ring array for performing RF (radio frequency) data acquisition with the plurality of ring-arrayed transducers. A needle holster is concentrically disposed in the ring array and is adapted to receive and direct an insertion instrument such as a needle, probe or extraction tool along an axis defined by a center of the ring array directed by the concentric needle holster. The tracking circuit includes a processor having instructions for instrument posture tracking and US imaging.

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.
