Abstract: An air management system for a vehicle having a first pneumatic circuit and a second pneumatic circuit, in which the first and second pneumatic circuits are pneumatically connected in a neutral position via a cross-flow mechanism. The first pneumatic circuit is configured to independently adjust air pressure of a first side of the vehicle. The second pneumatic circuit is configured to independently adjust air pressure of a second side of the vehicle. The system is configured to establish pneumatic communication between the first and second pneumatic circuits when the air management system is not independently adjusting the adjust air pressure of the first side of the vehicle and the air pressure of the second side of the vehicle in the cross-flow mode.

Abstract: An in-airport guitar kiosk and related methods for allowing air travelers an opportunity to relax and play guitar before or after flights (to improve the passenger journey) as well as the opportunity to try a novel travel guitar uniquely suited for air travel.

Abstract: A system and method for developing a course requires a plurality of participants that collaborate over a network, for example, a social network. A database stores an initial framework that defines a sequence of learning units for creating a desired learning environment for students, those learning units made of specifically ordered content objects. The learning units are identified by corresponding learning unit identifiers. A plurality of workstations coupled to the network are used for entry of reviewer information by the participants using the learning environment created for the students. The reviewer information comprise one or more comments entered by one participant about a learning unit or content object and a rank entered by anther participant about the comment, with the rank being correlated with a defined ranking standard. A processor processes the rank according to a predefined criteria to produce a ranking result that is associated with a learning unit identifier.

Abstract: In acquiring and managing measurement data relating to operating parameters of a dissolution tester, operating parameters are measured by operating one or more sensors. The measured operating parameters are transmitted from the sensors to a user computing device. It is then determined whether the measured operating parameters are in compliance or non-compliance with one or more standards, by comparing the measured operating parameters with a plurality of corresponding predefined values. The measured operating parameters and indications of compliance or non-compliance of each measured operating parameter are stored as a data record in a memory local or remote to the user computing device. The data record may be accessible by a computing device remote from the memory. The operating parameters may include, for example, shaft parameters.

Abstract: A fiber-optic probe includes first and second optical fibers disposed in a body, a liquid sampling region between ends of the fibers and a reflector, and apertures communicating with the sampling region. The probe may be inserted in media in a vessel. Optical signals are transmitted through the first fiber, the sampling region and second fiber. The sampling region is offset from other parts of the probe so that bubbles or particulates flow out from the sampling region without being obstructed by the probe.

Abstract: A computer system that may, for example, be used for educational purposes delivers content, e.g., instructional content, to a plurality of users, e.g., students. The content is presented to such users in units, e.g., learning units. Each unit has associated with it an assessment information relating to each one of the users. One or more systems, e.g., learning systems, present the one or more units to one or more users in a first interactive environment, e.g., a first learning environment, and a second interactive environment, e.g., a second learning environment, that is different from the first interactive environment. A digital rights and asset management application controls access to the content associated with each one of said one or more units according to corresponding unit identifiers, e.g., learning unit identifiers, and presents such content to the plurality of users in the first and second interactive environments for assessment purposes. An assessment application, e.g.

Abstract: A combined fishing rod and fishing line vibrator includes a housing of plastic material defined by a pair of body halves maintained in tubular alignment by interengaged pins and bores to form a tubular body having axially opposite first and second ends closed by first and second caps. A radial shoulder in the first cap defines an eccentric-receiving chamber housing a weight carried eccentrically by a shaft of an electric motor housed between the first radial shoulder and a second radial shoulder defining an electric motor-receiving chamber adjacent batteries within a battery chamber, the second cap having electrical connection means for energizing the electric motor, and a fishing line loop carried by the tubular body whereby when the vibrator is connected to a fishing rod, the latter is vibrated directly through vibrations caused by the eccentric weight and the fishing line is vibrated through the fishing line loop.
