    摘要: An unmanned craft having a fuselage, a propeller drive with a propeller being arranged in the tail portion of the fuselage for purposes of cruising, and a rocket assist propulsion system for the takeoff phase is releasably mounted to the fuselage, the improvement includes three spring biased thrust rods being secured to the frame and releasably engaging peripheral points of the craft. The thrust rods are radially pivotal in outer direction. Support points on the wings and the rudder engage front ends of the rods in contourmatching relationship but are disengageable therefrom.

    摘要: A processed representation of an audio signal having a sequence of frames is generated by sampling the audio signal within first and second frames of the sequence of frames, the second frame following the first frame, the sampling using information on a pitch contour of the first and second frames to derive a first sampled representation. The audio signal is sampled within the second and third frames, the third frame following the second frame in the sequence of frames. The sampling uses the information on the pitch contour of the second frame and information on a pitch contour of the third frame to derive a second sampled representation. A first scaling window is derived for the first sampled representation, and a second scaling window is derived for the second sampled representation, the scaling windows depending on the samplings applied to derive the first sampled representations or the second sampled representation.

    摘要: An audio encoder, an audio decoder or an audio processor includes a filter (12) for generating a filtered audio signal, the filter having a variable warping characteristic, the characteristic being controllable in response to a time-varying control signal (16), the control signal indicating a small or no warping characteristic or a comparatively high warping characteristic. Furthermore, a controller (18) is connected for providing the time-varying control signal, which depends on the audio signal. The filtered audio signal can be introduced to an encoding processor (22) having different encoding algorithms, one of which is a coding algorithm adapted to a specific signal pattern. Alternatively, the filter is a post-filter receiving a decoded audio signal.

    摘要: Disclosed is a computer-based technology for handling end-to-end business transactions in a TCP/IP-environment. A managing instance enables logon and provides a pool of IP addresses available for allocation. The managing instance allocates an IP address from the pool and establishes a tunneling IP connection between the managing instance and a user's device. The user's IP address together with any attributes relevant for accounting, authentication and authorization (AAA) are stored during the session time. The correlation between a user's authentication name and an IP address assigned to that name as well as the book-keeping of the validity of that correlation is handled using a session context. Any identification process for a user/subscriber who would like to use any service offered by an e-Service provider will be conducted solely using the assigned IP address.
