  • Publication number: 20220013286
    Abstract: A method for producing a spiral-shaped body, in particular an electric coil, made of an electrically conductive material. First, the material is wound about a mandrel in a casting mold in order to form a coil with a plurality of windings, and pressure is then exerted onto the coil in the axial direction of the coil. The pressure leads to a deformation and compression of the cross-section of the individual windings in the axial direction of the coil. By compressing the coil, an optimal use of space is achieved with an electric coil, for example for an electric machine.

  • Patent number: 11218754
    Abstract: Audio video synchronization and alignment or alignment of audio to some other external clock are rendered more effective or easier by treating fragment grid and frame grid as independent values, but, nevertheless, for each fragment the frame grid is aligned to the respective fragment's beginning. A compression effectiveness lost may be kept low when appropriately selecting the fragment size. On the other hand, the alignment of the frame grid with respect to the fragments' beginnings allows for an easy and fragment-synchronized way of handling the fragments in connection with, for example, parallel audio video streaming, bitrate adaptive streaming or the like.

    Abstract: An encoder for encoding secondary media data including metadata and control data for primary media data is shown, wherein the encoder is configured to encode the secondary media data using adding redundancy or bandlimiting and wherein the encoder is configured to output the encoded secondary media data as a stream of digital words. Therefore, the stream of digital words may be formed such that it is capable to resist a typical processing of a digital audio stream. Furthermore, processors for processing a digital audio stream are able to process the stream of digital words, since the stream of digital words may be designed as an audio-like or analog-like digital stream.
