    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.

    Abstract: A needle steering system and apparatus provides active, semi-autonomous control of needle insertion paths while still enabling a clinician ultimate control over needle insertion. The present teaching describes a method and system for controlling needle path as the needle is inserted by precisely controlling the rotation of the needle as it continuously rotates during insertion. This enables underactuated 2 degree-of-freedom (DOF) control of the direction and the curvature of the needle from a single rotary actuator. Control of the rotary motion is therefore decoupled from the needle insertion. The rotary motion controls steering effort and direction, while the insertion controls needle depth or insertion speed. In one implementation, the proposed method does not require constant velocity insertion, interleaved insertion and rotation, or known insertion position or speed. The insertion may be provided by a robot or other automated method, may be a manual insertion, or may be a teleoperated insertion.
