A crank sensor outputs a crank signal including an angle indicating part and a reference position indicating part. The video server adaptively selects the video encoding standard and the video encoding rate based upon factors such as the data transmission rate of the communication network, the processing speed of the video client device, or the type of the video content to be downloaded. The invention further relates to a method for the production of the inventive silane. The pivoting arm has a first end and a second end.
