Abstract: An attitude-adaptive hydrofoil apparatus, including: strut-braced wing assemblies, a horizontal wing assembly, connection plates, and attack angle adjusting plates. The strut-braced wing assemblies each include a bearing, at least one inclined tube, at least one inclined flow-guiding wing, and at least one stop dog. The horizontal wing assembly includes a horizontal tube, at least one horizontal flow-guiding wing, and at least one depth-locating wing. The attack angle adjusting plates each include an angle adjusting end plate having a hole. The strut-braced wing assemblies are symmetrically disposed at two sides of the horizontal wing assembly. The bearing is fixed on a vessel body by welding. The at least one inclined flow-guiding wing is sleeved on the at least one inclined tube, and is limited by the at least one stop dog. The attack angle adjusting plates are disposed at two ends of the horizontal tube, respectively.

Abstract: System and method for trackable applications including an application providing unit, a controller, and an incentive tracker. The application providing unit is adapted to send a trackable application upon request. The controller is adapted to receive interactions from the trackable application. The incentive tracker is adapted to select an incentive based on the interaction data. The controller is further adapted to send the selected incentive to the trackable application.

Abstract: System and method for delivering context aware applications including a content analyzer, a context aware application, a recommendation component, and a controller. The content analyzer is adapted to determine topics in content requested by a user. The context aware application repository contains one or more context aware applications. The recommendation component is adapted to select a context aware application from among the one or more context aware applications based on the determined topics. The controller is adapted to receive the request for a context aware application including information regarding the requested content and is adapted to send the selected context aware application to the requester of the selected context aware application.

Abstract: System and method for delivering context customized applications comprising a content analyzer, an application customizer, and a controller adapted. The content analyzer is adapted to determine topics in content requested by a user. The application customizer is adapted to customize an application based on the determined topics, to form a context customized application. The controller is adapted to receive the request for the context customized application including information regarding the requested content, and is adapted to send the context customized application to the requester of the context customized application.
