  • Patent number: 9444537
    Abstract: A device including a transmitter, a receiver and an arbiter. The transmitter transmits a first signal. The first signal has a fundamental frequency in a first frequency band of a first wireless protocol. The receiver receives a second signal. The second signal has a fundamental frequency in a second frequency band of a second wireless protocol. The first frequency band is adjacent to or at least partially overlaps the second frequency band. The arbiter allows the transmitter to transmit the first signal in the first frequency band while the receiver receives the second signal in the second frequency band. The arbiter also, if a power level of the first signal is less than a first threshold, changes: a modulation and coding scheme of the transmitter for the first signal; a modulation and coding scheme of the receiver for the second signal; or a multiple input and multiple output rank.

  • Patent number: 9245355
    Abstract: 3D mesh models are represented by three types of data: connectivity data, geometry data and property data. The surface of a 3D object is a triangle mesh. 3D meshes contain huge amounts of data that need to be compressed efficiently. Additionally to the common world coordinate system for the complete model and local coordinate system for a single triangle, an individual component coordinate system for each connected component is used. The component coordinate system is used to normalize the orientation of the respective component for quantization and de-quantization. This improves the accuracy of encoded 3D mesh models after quantization/de-quantization, particularly if a 3D mesh model comprises one or more distinct components.

  • Patent number: 9214042
    Abstract: A method for encoding vertex orientations, also known as normal components, of a 3D mesh model comprises a first clustering of the normal components, determining for each of the first clusters a sphere sector to which most of its elements belong, mapping normal components to a predefined sector, re-clustering the normal components in the predefined sector into second clusters, determining predictors for the second clusters and encoding a normal component by its residual, a reference to its predictor and data indicating which of said mirror mapping operations were performed. A sphere sector is obtained by dividing a sphere into m equal spherical segments and dividing each of said spherical segments into n equal sectors. The first clustering for the sector mapping and the second clustering for predictive coding result in an improved compression ratio.
