  • Patent number: 12661937
    Abstract: A tire (1) has improved handling and comprises a stiffening structure (7) comprising two stiffening elements (8), each extending continuously in the toroidal interior cavity (6) from a crown interface (81) connected to a radially inner face of the crown (23) to a bead interface (82) connected to an axially inner face of the bead (41). The stiffening structure (7) is distributed circumferentially around the entire circumference of the tire. The crown interface (81) is positioned, with respect to the equatorial plane (XZ), at an axial distance A at most equal to 0.45 times the axial width S and the bead interface (82) is positioned, with respect to a radially innermost point (I) of the axially inner face of the bead (41), at a radial distance B at least equal to 0.10 times the radial height H and at most equal to 0.5 times the radial height H.

  • Patent number: 12583258
    Abstract: The tire (10) has a stiffening structure (50) comprising a stiffening element (52, 53) anchored in or around radially inner reinforcing structures (60A) and a radially outer reinforcing structure (70A, 70B). Each stiffening element (52, 53) extending from one of the radially inner reinforcing structures (60A) comprises a portion (523) extending in the toroidal cavity (35) between first anchor points. Each stiffening element (52, 53) extending from the other of the radially inner reinforcing structures (60B) comprises a portion (524) extending in the toroidal cavity (35) between second anchor points. The portions (523) do not cross over in the toroidal cavity (35). The first anchor points are axially on the other side of the same side of the median plane (M) of the tire (10) as the second anchor points.

  • Patent number: 10523958
    Abstract: Method and apparatus of compressing a stream of pictures in parallel in a compression device, where the compression device includes at least a first and a second component, are described. A first portion of a first picture of a stream of pictures is processed in the first component of the compression device, while a second portion of a second picture of the stream of pictures is simultaneously processed in the second component of the compression device according to partial compression statistics associated with the second picture, where the partial compression statistics result from the processing of the second picture in the compression device when compression of the second picture is not yet completed.

  • Patent number: 10360695
    Abstract: A method and apparatus for enabling low latency compression of a stream of pictures are described. A first set of static regions of a current picture from the plurality of pictures is determined, where each region from the first set is static. A second set of regions of the current picture is determined, where the second set includes all regions of the current picture that are not included in the first set. Compression of the first set of regions is performed based on values of a first quantization parameter determined by a MAQ mechanism. The MAQ mechanism is operative to dynamically increase the compression quality of static regions. Compression of the second set of regions is performed based on values of a second quantization parameter determined by a rate control mechanism. The rate control mechanism is operative to compress the data stream according to a target bit rate.

  • Patent number: 10003802
    Abstract: A method and apparatus for compressing a data stream comprising a plurality of pictures are described. A first quantization parameter (QP) from a plurality of QPs is determined, for a static region in a current picture. The plurality of QPs change in accordance with a multi-step change from a start QP to a target QP and each one of the plurality of QPs is to be applied to a respective one from successive static regions in successive pictures. In response to determining, based upon statistics on static region(s) in the current picture which are associated with the first QP, that the first QP is selected, compression of the static region is caused based upon the first QP, and in response to determining that the first QP is not selected, compression of the static region is caused based upon a second QP that is greater than the first QP.
