Abstract: A method, apparatus and program product utilize an automated educational tool to generate or modify one or more multiple choice questions in a question set in connection with tracking a user's attention state to dynamically vary the difficulty of a user assessment performed by the automated educational tool and thereby encourage the user to pay greater attention to the material being presented to the user.

Abstract: A device for facilitating the formation of new bone tissue includes a body that defines an upper portion and a lower portion, the lower portion having a substantially frustum-like shape, the upper portion having a substantially cylindrical shape. The lower portion is adapted to be inserted into the medullary canal of a bone.

Abstract: Described here is a deep brain stimulation (“DBS”) approach that targets several relevant nodes within brain circuitry, while monitoring multiple symptoms for efficacy. This approach to multi-symptom monitoring and stimulation therapy may be used as an extra stimulation setting in extant DBS devices, particularly those equipped for both stimulation and sensing. The therapeutic efficacy of DBS devices is extended by optimizing them for multiple symptoms (such as sleep disturbance in addition to movement disorders), thus increasing quality of life for patients.

Abstract: A tool holder includes a body including a first half and a second half. The first half and the second half define an opening at a proximal end and an appliance cavity therebetween. A rotation element couples the first half of the body to the second half of the body. The first half and the second half are rotatable about an axis of rotation defined by the rotation element from a first configuration to a second configuration. In the first configuration the first half and the second half are in a facing relationship and define a cavity therebetween. In the second configuration the first half and the second half are in an end-to-end relationship and aligned on a longitudinal axis.

Abstract: An automated leveling system for maintaining a level of a surface, comprising a surface traveling device and a leveling module attached to the surface traveling device. The leveling module comprises a depression detector arm assembly, at least one computing device, and a level-sensing detector. The level-sensing detector senses a level of a surface as the surface traveling device operates across the surface. The level-sensing detector moves across the surface according to the operation of the surface traveling device, and transmits a depression reporting signal to the computing device. The depression reporting signal indicates the presence of a depression in the surface if the level-sensing detector contacts a depression in the surface over a depression threshold.

Abstract: A method of processing geological data is provided for input to a geostatistical modelling algorithm to predict a value for a parameter relating to a physical property of the Earth. An input data set corresponding to a measured geological parameter is processed to determine a characteristic function of the input data with respect to a geological measure. The input data is transformed to reduce spatial bias with respect to the geological distance measure by applying an inverse function. A statistical weighting is calculated for the transformation and the transformation and weighting are used to predict a representative value of the physical property corresponding to the measured geological parameter. A data processing apparatus and computer program product are also provided.

Abstract: An ice cube machine that generates ice cubes having an alcohol content of at least 2-5%. The ice cube machine operates at temperatures of no greater than 0° F., and typically at least 0° F. or colder. An ice dispensing system monitors the amount of ice cubes dispensed from the machine and can determine the amount of alcohol dispensed from the system.

Abstract: A method for selectively orienting molecules on a surface of a solid support. The method includes: (a) attaching a linker molecule to the surface of the solid support, the linker molecule including a head group that is capable of binding to the solid support, and a tail group that is capable of chelating to a metal ion; (b) subsequently treating the solid support with a solution containing the metal ion; (c) attaching a metal ion chelating tag to the molecules to form tagged molecules; and (d) capturing the tagged molecules on the solid support by contacting it with the tagged molecules to form a monolayer of molecules on the surface of the solid support in which a majority of the molecules are held in the same orientation with respect to the surface.

Abstract: An ergonomic scraper, such as a floor scraper using a standard replaceable blade, is provided. Embodiments include a scraper having an elongated handle, a scraper head for fixedly holding a blade mounted to a first end of the handle, an upper hand grip at a second end of the handle, and a lower hand grip between the first and second ends of the handle. The handle has an S-shape to reduce the angle between the blade and a workpiece. A pair of wheels is mounted near the scraper head for easily adjusting the blade attack angle. The scraper head is adjustable for changing the scraping angle of the blade to suit the user and/or the job.
