    摘要： Apparatus and methods for providing fluid such as water at a controlled temperature. In some embodiments, hot and cold fluid is provided to a thermostatically controlled mixing valve, which then provides fluid at a mixed temperature to a plumbing system. The thermostat provides a first loop for closed-loop control of fluid exit temperature, and preferably there is a second, electronically controlled closed loop for adjusting the temperature of fluid exiting the valve. In yet other embodiments the electronic control loop is fail-fixed, such that a loss of electrical communication to the actuator results in the actuator maintaining its last position. In yet other embodiments there is a system including a flow sensor and a recirculation pump such that the temperature of the fluid exiting the valve cannot be adjusted if there is insufficient flow, or if the pump is actuated.

    摘要翻译： 用于在受控温度下提供诸如水的流体的装置和方法。 在一些实施例中，将热和冷流体提供给恒温控制的混合阀，然后混合阀将混合温度的流体提供给管道系统。 恒温器提供用于闭环控制流体出口温度的第一回路，并且优选地存在用于调节离开阀的流体的温度的第二电子控制闭环。 在其他实施例中，电子控制回路故障固定，使得与致动器的电通信丢失导致致动器保持其最后位置。 在其他实施例中，存在包括流量传感器和再循环泵的系统，使得如果流量不足或者泵被致动，则不能调节离开阀的流体的温度。

    摘要： A contact free rotary transformer assembly can be used to transfer power and information between a stationary portion and a rotatable portion of a laser scanning device. The rotary transformer can consist of a pair of substantially parallel ferrite rings, each having disposed therein a coil for passing AC current. The assembly can use an optical fiber positioned near a rotational axis of the transformer to transfer optical information between the stationary and rotary portions. The optical fiber can include two portions connected by a rotational connection in order to allow the portions to rotate with respect to one another while maintaining the light path.

    摘要： Differences of electromagnetic (EM) properties between healthy and cancerous tissues allow detection of abnormal conditions occurring in a tissue of an animal, for example, intra-operative cancer detection. By using a time-varying EM field, electrical eddy currents are generated in the tissue sample, and assessed using phase-sensitive detection. In some aspects, a change in phase shift between the voltage in a receiver coil and the voltage in a driver coil provide a direct and immediate indication of differences in EM properties of specimens.
