    • Apparatus and an accompanying method for use in a conventional dynamic material testing system to advantageously provide enhanced self-resistive specimen heating. Specifically, a fixture (400) is added to the system. The fixture has two supporting arms (201, 451), each holding one of two opposing and conductive anvil assemblies (200, 453). The fixture applies adequate force to each arm sufficient to hold a specimen (466) in position between the anvil assemblies and establish a good abutting electrical contact between the specimen and each assembly but without exerting enough force to deform the specimen as it is being heated. Separate opposing and existing coaxially-oriented shafts (406, 408) controllably strike both arms and move the anvils together, hence squeezing the specimen and generating each deformation therein. Electrical heating current is controllably applied through the support arms, the anvils and the specimen in order to self-resistively heat the specimen in a predefined temporal manner with respect to the specimen deformations.
    • 用于常规动态材料测试系统中的装置和伴随方法有利地提供增强的自阻试样加热。 具体地说,在系统中添加固定装置(400)。 夹具具有两个支撑臂(201,451),每个支撑臂保持两个相对的和导电的砧座组件(200,453)中的一个。 夹具对每个臂施加足够的力,足以将样品(466)保持在砧座组件之间的适当位置,并且在样品和每个组件之间建立良好的邻接电接触,但是在试样被加热时不会产生足够的力使样品变形。 分离的相对和现有的同轴取向的轴(406,408)可控地撞击两个臂并将砧移动在一起,从而挤压样品并在其中产生每个变形。 通过支撑臂,砧座和试样可控地施加电加热电流,以便以相对于试样变形的预定时间方式对试样进行自电阻加热。

    • Methods and apparatus for dynamically adjusting the amount of power (or current) distributed to one or more connected devices via electrical interfaces. In one embodiment, the apparatus comprises a first module adapted to detect current drawn by a first set of ports, and a second module adapted to adjust the current provided to a second set of ports based on the detected current. The second module is also optionally adapted to distribute unreserved current among the devices according to an allocation protocol. In the exemplary context of a plurality of interconnected serial bus devices, the invention enables a device to draw more current than that required to be reserved for that device (such as to comply with a specification such as USB), yet without increasing the total amount of power which must be dedicated to the serial ports as a whole. Power supply efficiency may also be advantageously optimized.
    • 用于通过电接口动态调整分配给一个或多个连接设备的功率(或电流)量的方法和装置。 在一个实施例中,该装置包括适于检测由第一组端口抽取的电流的第一模块,以及适于基于检测到的电流来调整提供给第二组端口的电流的第二模块。 第二模块还可选地适于根据分配协议在设备之间分配未保留的电流。 在多个互连的串行总线设备的示例性上下文中,本发明使得设备能够比不需要为该设备保留的电流(例如符合诸如USB的规范)绘制更多的电流,而不增加总量 必须专门用于整个串行端口的电源。 还可以有利地优化电源效率。
