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: Devices and methods for capturing and imaging a specimen, such as a living organism, are disclosed. In some embodiments, a method for imaging a living organism in vivo includes placing at least one specimen into a hydrogel polymer on a substrate, and curing the hydrogel to embed the at least one specimen within the cured hydrogel such that the at least one specimen is kept alive and the movement of the at least one specimen within the cured hydrogel is restricted. The at least one embedded specimen can be imaged.

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.

Abstract: A microfluidic chip is provided for self-sorting highly motile, morphologically normal sperm cell with high DNA integrity from a fresh semen sample. The sperm self-sorting microfluidic chip has one or more inlet chambers, and sperm collection outlet chamber(s), and the middle of the channel features various micro-fabricated structures in different geometrical shapes and orientations, with varying periodicities and patterns, such as an array of micro-fabricated pillars that facilitate the transport of the active and healthy sperm into the outlet chamber.

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: An equine respiratory detection device provides an inexpensive, portable appliance for evaluating equine health. A muzzle or mouthpiece attaches to the equine mouth region for sealably engaging with the respiratory pathway. The mouthpiece attached to a tubular vessel having a volumetric sensing apparatus for measuring respiratory inflow and outflow rates. The sensing apparatus includes a hot wire anemometer and sensing circuit for sensing flow rates based on changing electrical characteristics of a sensing element resulting from a temperature and humidity of the respiratory gases. Inhaling results in inflow gases having a cooling effect on a thermistor which affects the current flow in the sensor circuit. Similarly, exhaled outflow gases have increased temperature and humidity which allow identification of bidirectional flow and computation of an overall respiration volume to the equine patient subject.

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.
