    摘要： The present invention is a high efficiency permanent magnet machine capable of maintaining high power density. The machine is operable over a wide range of power output. The improved efficiency is due in part to copper wires with a current density lower than traditional designs and larger permanent magnets coupled with a large air gap. In a certain embodiment wide stator teeth are used to provide additional improved efficiency through significantly reducing magnetic saturation resulting in lower current. The machine also has a much smaller torque angle than that in traditional design at rated load and thus has a higher overload handling capability and improved efficiency. In addition, when the machine is used as a motor, an adaptive phase lag compensation scheme helps the sensorless field oriented control (FOC) scheme to perform more accurately.

    摘要翻译： 本发明是能够保持高功率密度的高效率永磁电机。 该机器可在广泛的功率输出范围内工作。 提高的效率部分是由于电流密度低于传统设计的铜线，并且具有大的气隙耦合的较大的永磁体。 在某些实施例中，通过显着地减小导致较低电流的磁饱和度，使用宽的定子齿来提供额外的改进的效率。 该机器在额定负载下也具有比传统设计小得多的扭矩角，因此具有更高的过载处理能力和更高的效率。 此外，当机器用作电动机时，自适应相位滞后补偿方案有助于无传感器场定向控制（FOC）方案更准确地执行。

    摘要： Various embodiments of the present invention are directed to nanoscale electronic devices that provide nonvolatile memristive switching. In one aspect, a two-terminal device (600) comprises a first electrode (602), a second electrode (604), and an active region (606) disposed between the first electrode and the second electrode. The active region includes a mobile dopant (608), and a fast drift ionic species (610). The fast drift ionic species drifts into a diode-like electrode/active region interface temporarily increasing conductance across the interface when a write voltage is applied to the two-terminal device to switch the device conductance.

    摘要： A system and method for troubleshooting errors that occur during token requests. An identity provider generates a session ID and uses the session ID when logging events that occur during handling of the request. Multiple servers, processes, or threads may use the same session ID. The session ID may be sent with an error message to the requester. An ID of one or more servers that processed the request may also be sent to the requester. Upon receiving the error message, the requester may provide the error information to an administrator, who uses the information to retrieve associated logged events.

    摘要： A water-based ink for use in a computer-to-plate inkjet printing and a preparation method therefor. A polymer of 5 to 40 wt %, an additive of 0.01 to 10 wt %, a dye or pigment of 0.01 to 10 wt %, an organic solvent of 1 to 30 wt %, an anti-foaming agent of 0 to 5 wt %, and deionized water are stirred and mixed at room temperature. When the polymer is dissolved, the mixed solution is filtered. The filtrate is the water-based ink. The water-based ink is sprayed via a computer-to-plate machine onto a surface of a metal substrate (which may be an aluminum plate, a zinc plate, or a copper plate) to form a graphic region. A printing plate allowing for computer-to-plate printing is acquired after solidification. The printing plate acquired is allowed to achieve a halftone dot reproduction rate between 2 and 99% and a recognition rate of 175 lpi.
