Methods and apparatus for compressing and decompressing a higher order ambisonics representation
Higher Order Ambisonics represents three-dimensional sound independent of a specific loudspeaker set-up. However, transmission of an HOA representation results in a very high bit rate. Therefore compression with a fixed number of channels is used, in which directional and ambient signal components are processed differently. The ambient HOA component is represented by a minimum number of HOA coefficient sequences. The remaining channels contain either directional signals or additional coefficient sequences of the ambient HOA component, depending on what will result in optimum perceptual quality. This processing can change on a frame-by-frame basis. |

Codebook generation for cloud-based video applications
Techniques are disclosed for the improvement of vector quantization (VQ) codebook generation. The improved codebooks may be used for compression in cloud-based video applications. VQ achieves compression by vectorizing input video streams, matching those vectors to codebook vector entries, and replacing them with indexes of the matched codebook vectors along with residual vectors to represent the difference between the input stream vector and the codebook vector. The combination of index and residual is generally smaller than the input stream vector which they collectively encode, thus providing compression. The improved codebook may be generated from training video streams by grouping together similar types of data (e.g., image data, motion data, control data) from the video stream to generate longer vectors having higher dimensions and greater structure. This improves the ability of VQ to remove redundancy and thus increase compression efficiency. Storage space is thus reduced and video transmission may be faster. |

Permanent magnet embedded-type rotating electric machine and manufacturing method thereof
Cracking and flying around of permanent magnets in a permanent magnet embedded-type rotating electric machine is prevented. Thermally hardening FRP is used as a reinforcement sheet, and the reinforcement sheet is wrapped around the periphery of a permanent magnet and caused to adhere to the surface of the permanent magnet by being thermally hardened. Subsequently, the permanent magnet to which the reinforcement sheet is adhering is embedded in magnet embedding holes of the rotor. The surface of the reinforcement sheet after thermal hardening is in a state of not being attached to the inner wall surface of the magnet embedding holes. Consequently, no stress caused by the difference between the linear expansion coefficients of the rotor and permanent magnets acts on the permanent magnets when the temperature of the rotor rises, and cracking of the permanent magnets can thus be prevented. |

PEDOT:PSS composite films having enhanced thermoelectric properties
A PEDOT:PSS film having enhanced thermoelectric properties is doped with DMSO and a binary secondary dopant, such as PEO. The composition of such film causes the ratios of PEDOT in bipolaron states to be increased. As a result, the Seebeck coefficient, the electrical conductivities, and power factor of the film are increased, thereby increasing the efficiency of the film. Thus, a thermoelectric device that uses the film is able to achieve enhanced operating performance. |
