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 digital instructional environment leverages an infrared eye-tracker to monitor a learner's reading and viewing of text and simulations for subject matter. The system detects out-of-order reading/viewing patterns that could lead to poor comprehension. The digital learning environment communicates with other tutorial components including simulation environments, pedagogical agents and may respond in real-time to such patterns with messages that guide learners (knowledge acquirers) to return to effective reading/viewing patterns so as to promote effective construction of mental model(s) developed during knowledge acquisition/learning.

Abstract: A volatile liquid storage container has combustion resistance properties from a flexible sock or tube constructed of fire resistant fibers coupled to a neck of the storage container to prevent flame flash-back into the storage container. The storage container defines an enclosed volume having an orifice in the container material leading to a neck for pouring and filling the enclosed volume for exchanging the contents therein. The tube is elongated and surrounds a circumference of the orifice for engaging any ignition source entering through the orifice. The flexible nature of the tube or sock allows it to extend to an opposed interior surface of the enclosed volume, and ensures that the tube or sock is immersed in the fluid for encircling any ignition path to the volatile liquid without interfering with an ability to pour or refill the container.

Abstract: An apparatus comprising a crank-slider linkage and a rocker link. The crank-slider linkage has a crank coupled to the slider by a jointed connecting rod. The jointed connecting rod has a first link and a second link. The first link is coupled to the second link by a first revolute joint. The first link is coupled to the crank and has a longitudinal axis. The rocker link has a rocker end and a ground end. The rocker end is coupled to the jointed connecting rod. The ground end is coupled to ground by a second revolute joint. The rocker link and the second link are disposed on a common side of the longitudinal axis.

Abstract: The present invention relates to a novel device and method for the detection of lithium ions in a biological fluid. In a preferred embodiment, the present invention provides a novel compound and a optical sensor which incorporates said compound for the detection of lithium ions. Additionally, the present invention provides a method of detecting lithium ions which comprises placing the novel optical sensor into communication with a biological fluid. Once the novel compound of the present invention encounters a lithium ion(s), a fluorescence is generated, the intensity of which is measured and allows for the determination of lithium ion concentration. The present invention provides a medical professional with the ability to selectively determine lithium ion concentration in a biological fluid thereby facilitating the treatment of various diseases, such as manic-depressive illness.
