Abstract: A system includes a first Tx circuit, a first Rx circuit, a redriver circuit, and an equalization circuit. The redriver circuit includes a second Rx circuit and a second Tx circuit. The second Rx circuit is coupled to the first Tx circuit, and the second Tx circuit is coupled to the first Rx circuit. The equalization circuit includes at least one processor to generate a sample search space with a plurality of samples. The sample search space is based on a plurality of Rx equalization parameters and a plurality of Tx equalization parameters. The at least one processor is further to partition the sample search space into a set of successively smaller partitions. A set of equalization parameters for the first Tx circuit, the first Rx circuit, the second Tx circuit, and the second Rx circuit is generated based on the set of successively smaller partitions.

Abstract: A method of generating a user interface includes obtaining input data indicative of respective positions of a plurality of elements within an input plane and generating a model of a surface of a three-dimensional structure. The surface has circular symmetry and includes two curved polar caps and a curved equatorial belt, wherein a curvature of each of the polar caps is greater than a curvature of the equatorial belt. The method includes mapping the elements to respective positions on the model, and determining a position and orientation of a virtual camera, wherein the determined position of the virtual camera is exterior to the model. The method includes determining a field of view of the virtual camera containing a concave interior portion of the model, and rendering a projection of the model corresponding to the determined field of view and comprising elements mapped to positions on the concave interior portion.

Abstract: A chair assembly is provided. The chair assembly includes locking members arranged at a joint between a chair chassis and a seat back support and joints between the chair chassis and two armrests correspondingly. An assembly block of the locking member is formed on the chair chassis while an assembly groove of the locking member is formed in both the seat back support and the respective armrests for being fit on the assembly block of the chair chassis correspondingly. Now a tenon disposed on the assembly block is capable of being engaged with a locking hole arranged at the assembly groove. A positioning part elastically abuts against the opposite side walls of the assembly groove. Thereby assembly of the chair chassis with both the seat back support and the armrests is finished easily and quickly. The chair assembly is more comfortable and safe for users sitting thereon.
