摘要： A device for reducing evaluation time of a matrix representing an electrical circuit. Conductance values of each circuit component in the circuit are written to corresponding models utilizing non-blocking writing techniques. The matrix is represented by a reduced memory structure where each matrix node is represented by a matrix element structure having at least one pointer to a conductance value contained in a model structure corresponding to a circuit component that contributes to a value of the matrix node. A set of rows or columns of the matrix are then processed to calculate final matrix node values independently.

摘要翻译： 一种用于减少表示电路的矩阵的评估时间的装置。 使用非阻塞写入技术将电路中每个电路元件的电导值写入相应的模型。 矩阵由减小的存储器结构表示，其中每个矩阵节点由矩阵元素结构表示，该矩阵元素结构具有至少一个指向包含在对有助于矩阵节点的值的电路分量的模型结构中的电导值的指针。 然后处理一组矩阵的行或列以独立地计算最终矩阵节点值。

摘要： An infant support assembly for supporting an infant using a mesh material to permit free flow of air around the infant to minimize the potential for smothering of the infant. The infant support assembly includes a frame assembly and a mesh material coupled to the frame assembly to form a support surface. Additionally, mesh side rails are provided for facilitating retention of an infant on the support surface.
