Abstract: Abstract The present technology provides cutting boards and storage containers that are composed of natural products. A formulation is used to layer onto and/or impregnate a substrate which is a fabric. The cutting board is soft enough to reduce dulling of knives, while not being permanently damaged by the knife cuts. It has anti-bacterial properties, is bendable and foldable, and can be rolled into a tube, but rigid enough to maintain its planar shape. It is light weight and non-skid.  The cutting boards are: washable; compostable; self-healing; flexible; soft enough to minimize knife damage; stain resistant; anti-microbial; and water resistant. The same combination can be used to form storage containers. Date Recue/Date Received 2020-10-06

Title: Post-filtre de basses selectif
Inventor: RESCH BARBARA
IPC: G10L19/125
Filed: 2011-06-23
Abstract: Dans un aspect, linvention concerne un procédé de codage audio caractérisé par une décision à savoir si le dispositif qui décodera le train de bits résultant devrait appliquer un post-filtrage, notamment latténuation du bruit interharmonique. Ainsi, la décision dutiliser le post-filtrage, qui est encodé dans le train de bits, est prise séparément de la décision quant au mode de codage le plus approprié. Dans un autre aspect, linvention concerne un procédé de décodage audio qui comporte une étape de décodage suivie dune étape de post-filtrage, notamment latténuation du bruit interharmonique, et caractérisée par une étape de désactivation du post-filtre, conformément à de linformation de post-filtrage encodée dans le signal du train de bits. Un tel procédé est parfaitement adapté à des signaux audio dorigine mixte en raison de sa capacité à désactiver le post-filtre en fonction de linformation de post-filtrage seulement et, donc, indépendamment de facteurs tels que le mode de codage actuel.

Patent CA-2929986-A1 (CA)
Inventor: LI XIANG
IPC: H04N19/30
Filed: 2014-12-17
Abstract: Techniques are described for signaling information used to generate three-dimensional (3D) color lookup tables for color gamut scalability in multi-layer video coding. A lower layer of video data may include color data in a first color gamut and a higher layer of the video data may include color data in a second color gamut. To generate inter-layer reference pictures, a video encoder or video decoder performs color prediction using a 3D lookup table to convert the color data of a reference picture in the first color gamut to the second color gamut. According to the techniques, a video encoder may encode partition information and/or color values of a 3D lookup table generated for color gamut scalability. A video decoder may decode the partition information and/or color values to generate the 3D lookup table in order to perform color gamut scalability.
