    • Systems and methods for implementing a floating point fused multiply and accumulate with scaling (FMASc) operation. A floating point unit receives input multiplier, multiplicand, addend, and scaling factor operands. A multiplier block is configured to multiply mantissas of the multiplier and multiplicand to generate an intermediate product. Alignment logic is configured to pre-align the addend with the intermediate product based on the scaling factor and exponents of the addend, multiplier, and multiplicand, and accumulation logic is configured to add or subtract a mantissa of the pre-aligned addend with the intermediate product to obtain a result of the floating point unit. Normalization and rounding are performed on the result, avoiding rounding during intermediate stages.
    • 用于实现浮点融合乘法并用缩放(FMASc)操作累加的系统和方法。 浮点单元接收输入乘法器,被乘数,加数和缩放因子操作数。 乘法器块被配置为乘法乘法器和乘法器的尾数以产生中间乘积。 对准逻辑被配置为基于加法器,乘法器和被乘数的缩放因子和指数来将加数与中间乘数预对齐,并且累加逻辑被配置为将预对齐加法的尾数与中间值相加 产品获得浮点单位的结果。 对结果执行归一化和舍入,避免中间阶段的四舍五入。

    • One or more techniques and/or systems are disclosed for identifying a location of a mobile device (e.g., with user consent). A set of one or more indications of received signal strength (RSS) may be received, comprising a first RSS from a first access point (AP). The set of RSS indications may be used to identify a grid area, comprising a first grid space. An expected distance between the first grid space and the first AP may be identified using the first RSS. The expected distance can be combined with a first known distance between the first grid space and the first AP to determine a first grid score for the first grid space. A second grid score may be determined for a second grid space (e.g., and a third, fourth, etc.), and the grid space comprising a desired grid score (e.g., highest) may be selected as the mobile device location.
    • 公开了一种或多种技术和/或系统来识别移动设备的位置(例如,经用户同意)。 可以接收一组接收信号强度(RSS)的一个或多个指示,其包括来自第一接入点(AP)的第一RSS。 可以使用一组RSS指示来识别包括第一网格空间的网格区域。 可以使用第一RSS来识别第一网格空间和第一AP之间的预期距离。 预期距离可以与第一网格空间和第一AP之间的第一已知距离组合以确定第一网格空间的第一网格得分。 可以针对第二网格空间(例如,第三,第四等)确定第二网格得分,并且可以选择包括期望网格得分(例如,最高)的网格空间作为移动设备位置。

    • A paint roller with an end-surface blocking structure is provided with a mounting stem coupled to a handle, a roller sleeved on the mounting stem, a connecting sleeve sleeved on the mounting stem, and an end-surface blocking piece pivoted to the connecting sleeve. The pivot connection of the connecting sleeve with the second pivot allows the connecting sleeve to pivot around the first direction and allows the end-surface blocking piece which is pivoted to the connecting sleeve to pivot around the second direction, so that the end-surface blocking piece is capable of rotating in two different directions, which improves flexibility when operating the paint roller.
    • 具有端面阻挡结构的涂漆辊具有联接到手柄的安装杆,套在安装杆上的滚子,套在安装杆上的连接套筒和枢转于连接套筒的端面阻挡件 。 连接套筒与第二枢轴的枢转连接允许连接套筒围绕第一方向枢转,并允许枢转到连接套筒的端面阻挡件围绕第二方向枢转,使得端面阻塞 能够在两个不同的方向上旋转,这在操作油漆辊时提高了柔性。
