Title: Method for assembling/dismounting components of a wind power plant
Inventor: WOBBEN ALOYS
IPC: F03D11/00
Filed: 2003-05-23
Abstract: The present invention concerns a wind power installation and a method of fitting/removing components of a wind power installation. So that a crane is tied in to a lesser degree in fitting/removing components of a wind power installation, in a wind power installation according to the invention at least one cable passage means is provided in the region of the pylon head for passing through a hauling cable from a winch. The object is further attained by a method of fitting/removing components of a wind power installation comprising the steps: - laying a hauling cable from the winch to at least one deflection roller in the region of the pylon head and further to the component to be fitted/removed, - attaching the hauling cable to the component, and - releasing and letting down or pulling up and fixing the component. In that respect the invention is based on the realisation that at least a part of the components of a wind power installation can be fitted or replaced even without the aid of a crane if a suitable lifting apparatus is available. The solution according to the invention avoids expensive and complicated additional installations on any wind power installation. Nonetheless a versatile lifting apparatus is quickly available at low cost.

Abstract: A novel system and method of video assisted music instrument collaboration over distance. The system and method enable a musician to play a music instrument at one location and have the played music recreated by a music instrument at another location is provided. The system and method can be used to provide distance education for musical instrument instruction and, in this case, each student and instructor of the system has an end point which can connect to other end points in the system to exchange music data, preferably MIDI data, and videoconferencing data through a data network such as the Internet. The system and method can also be used for performances wherein a musician at a first end point plays an instrument and music data, representing the music played, is transferred to a second end point where the music played at the first end point is reproduced and one or more other musicians at the second end point play with the reproduced music in a musical performance. Preferably, each end point includes a music processing engine which buffers data received from another end point to remove the effects of transmission delays and fitter and to discard overly delayed data and to prevent damage to the music instrument at the end point due to undue network delays. Further, the music processing engine can inform the users when network performance is responsible for improper and/or undesired music playback by the instrument at the end point. This buffering by the music processing engine can also allow the synchronization of a video conferencing system between the end points with the playing of music by the instruments at the end points.

IPC: H04W4/90
Filed: 1999-12-13
Abstract: An internal calibration method may be employed to mitigate the effects of transfer function variations on subsequent time measurements, in a wireless location system. The inventive method includes the steps of injecting a stable, known wideband signal into a receiver system of the wireless location system; using the wideband signal to estimate the transferfunction across a prescribed bandwidth of the receiver system; and using the estimate to mitigate the variation of the transferfunction on subsequent time measurements. The wideband signal maybe a comb signal characterized by multiple discrete frequencies and consistent amplitude and spacing between the discrete frequencies, and the estimate of the transfer function may be weighted by a quality factor prior to mitigation of the effects of the transfer function.
