Abstract: A rotatable nacelle includes an engine inlet configured to receive air and an inlet air management system (IAMS). The IAMS includes a primary inlet configured to selectively allow air to flow into a duct associated with the engine air inlet via the primary inlet and a secondary inlet configured to selectively allow air to flow into the duct associated with the engine air inlet via the secondary inlet. The secondary inlet is configured to receive an air filter.

Abstract: Golf club heads having sensors configured to measure one or more swing parameters are provided. The golf club head may include several gyroscopes and accelerometers. In one embodiment, the club head contains three gyroscopes that measure angular rate data along different orthogonal axes. At least one gyroscope may an analog gyroscope. Accelerometers may provide data regarding the three orthogonal axes associated with the gyroscopes. The club head may further include software and/or hardware that perform computer-executed methods for determining one or more swing parameters. Exemplary club heads may include a display device for displaying an output of the swing parameter(s). Further aspects of the invention relate to novel methods and algorithms for calculating measurements relating to the swing parameters.

Abstract: An interactive voice response calling system (1) for automatically dialling a plurality of telephone numbers includes database (10) containing records of dialling information for a dialling campaign. A dialler (20) translates the records i the database into dialling instructions. A calling unit (40) initiates a plurality of calls based on the dialling instruction An interactive voice response unit (30) is operably connected to the calling unit (40) upon verification by the calling unit (40) that the connected call is answered by a person. The interactive voice response unit (30) includes a natural language recognition engine that automatically determines the language of a person and responds in the determined language and storage for temporarily storing answers to the dialling campaign.
