Abstract: In some embodiments, an electronic device presents information about, and facilitates downloading of, featured applications in an app store application. In some embodiments, an electronic device facilitates browsing of applications and games by category. In some embodiments, an electronic device facilitates presentation of information about in-app purchases for a game or application in an app store application. In some embodiments, an electronic device facilitates the purchase of in-app purchases for the games or applications that are available on the electronic device. In some embodiments, an electronic device facilitates the download/purchase of games, applications and/or in-app purchases from outside of an app store application that is for browsing such content available on the electronic device. In some embodiments, an electronic device autoplays media content corresponding to applications (e.g., games, non-game applications, etc.

Abstract: A gas filling apparatus for filling a plurality of gas storage vessels with a gas, the apparatus comprising a plurality of gas filling ports, each port configured to introduce gas into one of the gas storage vessels, and a controller configured to supply gas to the gas filling ports for filling the vessels and to control the supply of gas to all of the gas filling ports based on a property of any one of the vessels.

Abstract: Conventional techniques for automatically evaluating and grading assignments are generally ill-suited to evaluation of coursework submitted in media-rich form. For courses whose subject includes programming, signal processing or other functionally expressed designs that operate on, or are used to produce media content, conventional techniques are also ill-suited. It has been discovered that media-rich, indeed even expressive, content can be accommodated as, or as derivatives of, coursework submissions using feature extraction and machine learning techniques. Accordingly, in on-line course offerings, even large numbers of students and student submissions may be accommodated in a scalable and uniform grading or scoring scheme. Instructors or curriculum designers may adaptively refine assignments or testing based on classifier feedback.

Abstract: A high frequency cathode heater supply for a microwave source includes a SMPS inverter and an isolation transformer having a primary winding arranged to be powered by the SMPS inverter, a monitor winding passing through primary core assemblies of the primary winding and a secondary winding arranged for connection to the cathode heater. A current monitor is arranged to monitor a current in the primary windings. Signal processing modules are arranged to receive a first input signal from the monitor winding indicative of a voltage across the cathode heater and a second input signal from the current monitor indicative of a current through the cathode heater. The signal processing modules are arranged to output a control signal to the SMPS inverter to control power supplied to the cathode heater dependent on a monitored resistance of, or monitored power supplied to, the cathode heater as determined from the first input signal and the second input signal.

Abstract: A system and method of displaying presentation slides. In one aspect, the system and method provides presentation slides based on a user request for information. Both the request information and the slides are associated with identifiers. A set of slides is chosen by determining whether there are any corresponding identifiers between the request for information and the presentation slides. The slides are also chosen such that the set of slides does not include any slides associated with identifiers which are a proper subset of the identifiers of any other slide in the set.

Abstract: A method for moving seismic streamers or acoustic energy sources through water in marine geophysical operations. The equipment can be deployed or retrieved from one or more vessels, and two or more tow vehicles maneuver seismic streamers through the water independently of a seismic vessel. Manned or unmanned tow vehicles can tow the streamers ahead of, behind, or to the side of a seismic vessel, or can form an array independent of the seismic vessel. Tow vehicles can be located at both ends to change the tow direction. The invention is particularly useful in customizing an array configuration, in reorienting the array at the end of each survey line, and permits deployment of receivers and sources in different combinations. By decoupling the tow vehicles and streamers from the source vessel, turning time at the survey region borders and the possibility of streamer entanglement is significantly reduced.
