    • An apparatus which provides the ability to charge or power multiple devices from multiple different power sources, and to communicate electronic data to and from one of the devices. The apparatus utilizes simple construction, requiring no active electronics, thereby reducing the cost of production and the reliability of the device. The apparatus employs a single USB connection cable with connectors on both ends and a second power-only cable and connector which is connected to the power wires of the USB cable and thereby is able to power a second portable device from a single USB port. USB master provide sufficient power for two average portable devices without additional circuitry. Moreover, restricting the data path to only one device also eliminates the need for USB hub circuitry. Finally, greater end user flexibility is provided by using a USB male connector as the source of the data and power connection, a USB female connector for the output of the data and power connection, and a standard barrel-type power connector for the power-only output connection. Having two different output connectors ensures that the user will not confuse the two connectors.
    • 一种提供从多个不同电源对多个设备进行充电或供电的能力以及将电子数据传送到设备之一或从设备之一传送电子数据的设备。 该设备采用简单的结构,不需要有源电子元件,从而降低了生产成本和设备的可靠性。 该装置采用单个USB连接电缆,其两端具有连接器,以及第二电源电缆和连接器,其连接到USB电缆的电源线,从而能够从单个USB端口为第二便携式设备供电。 USB主机为两个平均的便携式设备提供足够的电力,无需额外的电路。 而且,将数据路径限制在一个设备上也不需要USB集线器电路。 最后,通过使用USB公连接器作为数据和电源连接的来源,提供用于输出数据和电源连接的USB母连接器以及用于电源连接的标准机筒式电源连接器来提供更大的终端用户灵活性, 只输出连接。 具有两个不同的输出连接器可确保用户不会混淆两个连接器。

    • In one embodiment, a computer readable medium comprises at least first instructions and second instructions. The first instructions, when executed, compute a first plurality of routes. Each route of the first plurality of routes corresponds to a respective net of a plurality of nets in an integrated circuit layout, and represents a theoretically optimal route of the respective net according to a graph theory based algorithm. The second instructions, when executed, compare each of the first plurality of routes to a corresponding route of a current plurality of routes, each of the current plurality of routes corresponding to the respective net of the plurality of nets and currently existing in the integrated circuit layout. A method is also contemplated.
    • 在一个实施例中,计算机可读介质至少包括第一指令和第二指令。 第一指令在执行时计算第一组多个路由。 第一多个路线的每个路线对应于集成电路布局中的多个网络的相应网络,并且根据基于图论的算法表示相应网络的理论上最佳的路由。 所述第二指令在执行时将所述第一多个路由中的每一个与当前多个路由的对应路由进行比较,所述多个路由中的每一条路由对应于所述多个网络的相应网络,并且当前存在于所述集成电路中 布局。 也考虑了一种方法。
