Multi-component phase change material flame retardant, method for preparing, and application thereof
Publication number: 20240327711Abstract: The present disclosure relates to a flame retardant composed of multi-component phase change material particles. These particles consist of paraffin wax, nano-flame retardant, and conventional flame retardant. The phase change material is modified with nano-flame retardant and physically coated with conventional flame retardant. The multi-component phase change material flame retardant is formed by creating a two-layer nucleus-shell structure. The nucleus core is made up of the conventional flame retardant, while the shell layer is composed of the nano-flame retardant doped phase change material. The multi-component flame retardant material combines the performance advantages of phase change material, nano flame retardant, and conventional flame retardant.

Patent number: 11831874Abstract: This disclosure describes techniques for performing semi-global matching (SGM) path cost compression. In some examples, the techniques may perform disparity-dependent sub-sampling of a set of SGM path costs where the sub-sampling ratio is determined based on a candidate disparity level. The sub-sampled SGM path costs may be stored in a memory. When retrieved from memory, the sub-sampled SGM path costs may be interpolated to reconstruct the other path costs not stored in the memory. The reconstructed path costs may be used for further SGM processing. In further examples, the techniques may perform disparity-dependent quantization on the SGM path costs or the sub-sampled SGM path costs, and store the quantized SGM path costs in memory. The techniques of this disclosure may reduce bandwidth as well as reduce the memory footprint needed to implement an SGM algorithm.Type: GrantFiled: December 1, 2021Date of Patent: November 28, 2023Assignee: Texas Instruments IncorporatedInventors: Do-Kyoung Kwon, Jing-Fei Ren, Darnell Moore
