    • An auto darkening eye protection device including a shutter assembly, a control circuit, and a power supply. The control circuit includes a sensing circuit for sensing the occurrence of welding, and a delivery circuit to provide signals to the shutter assembly to cause the shutter assembly to transition to the dark state. The power supply supplying power to the control circuit and the delivery circuit. The power supply including a power regulation circuit, and a solar power supply supplying electrical power to the power regulation circuit and the sensing circuit. The power regulation circuit limiting the voltage of the solar power supply to a predetermined voltage to provide a stable reference voltage.

    • In accordance with the present invention, a telephony control fault tolerance technique is provided. In one embodiment of the technique of the present invention, a computer-telephony agent (CTI) workstation is provided with a primary telephony control communication path between primary telephony control mechanism external to the workstation and a telephony application interface (TAPI) process, for use in controlling a telephony device in the workstation, internal to the workstation. In the event of failure of the primary path, a secondary telephony control communication path may be established between the TAPI process and a secondary telephony control mechanism that may be comprised in the workstation.
    • 根据本发明,提供了一种电话控制容错技术。 在本发明的技术的一个实施例中,计算机电话代理(CTI)工作站被提供有在工作站外部的主电话控制机构和电话应用接口(TAPI)过程之间的主电话控制通信路径,以供使用 在工作站内部控制电话设备。 在主路径故障的情况下,可以在TAPI进程和可能包含在工作站中的辅助电话控制机制之间建立辅助电话控制通信路径。
