Abstract: A system ensures the correct type of fuel is dispensed in an aircraft while removing the introduction of human error in the refueling process. The system includes an RFID tag disposed at one or more aircraft that electronically stores data such as engine type, engine hours, fuel type, tail number, and pilot/subscriber data for the aircraft on which the RFID tag is disposed. An RFID reader is disposed at or near a fuel dispensing mechanism, such as a fuel truck or tank. A signal indicative of fuel type is emitted from the RFID tag to the RFID reader. RFID tags on aircraft that are enrolled in the system's subscription service enable aircraft to be recognized by a module operating the fuel dispensing mechanism. Based on a comparison performed by the module, authorization to begin fueling is either permitted or declined.

Abstract: A lift generation system embodying tetrahedral lifting cells capable of lift through the inflation of lighter than air gas. During an initial lift, the tetrahedral lifting cells may be assembled into larger geodesic shells. The assembled geodesic shell is capable of generating greater lift through filling the enclosed volume they defined with additional lighter than air gas.

Abstract: An unloading system for use in a storage structure having a sidewall that contains granular stored material. A reclaiming portion is spaced from the sidewall and has a floor portion that extends from a discharge opening toward the sidewall. The floor portion of the reclaiming portion is supported above the floor of the storage structure. The reclaiming portion may move with respect to the sidewall and is isolated from movement with respect to the sidewall of the storage structure. Seals between the reclaiming portion and the sidewall prevent the stored material from bypassing the reclaiming portion so that any discharge of the stored material occurs through the discharge opening.

Abstract: The present disclosure concerns systems and methods for generating application-control policies. A system may receive application-usage data for a set of devices. The application-usage data may identify binaries with which a user interacted. The system may determine one or more application-usage characteristics for one or more devices in the set of devices based at least in part on the application-usage data and may rely solely on data associated with the binaries with which the user interacted. The system may identify a set of candidate devices based on the one or more application-usage characteristics. The application-usage characteristics may include a measure of distinct applications used during a specified time period and a measure of variability of application usage across a set of specified time periods. The system may generate an application-control policy for the set of candidate devices based on application-usage data for the set of candidate devices.

Abstract: The present disclosure relates to the determination of analytes in a sample using chromatography. The present disclosure provides methods of separating an analyte from a sample. A mobile phase is flowed through a chromatography column. The mobile phase includes about 0.005% (v/v) to about 2.50% (v/v) difluoroacetic acid and less than about 100 ppb of any individual impurity, especially metal impurities. A sample including the analyte is injected into the mobile phase. The analyte is separated from the sample.

Abstract: The invention is embodied in an apparatus for extending the human back. The preferred apparatus has a frame of transverse and longitudinal members, and a roller 20 rigidly supported from below by a transverse member. The space above the roller and frame is open so that a user can lie face up on the roller and grab the longitudinal members with each hand to extend the back over the top of the roller. The user then lowers his hips to extend the spine as much as desired. The user can roll the spine, vertebrae by vertebrae, from the base of the occipital to the sacrum.
