    • An image forming device includes a web server, and serves applets to a communicatively coupled computer. The applets execute on the computer, and control one or more operations and/or monitor one or more conditions or sensors in the image forming device. An applet may provide detailed instructions to the computer user as a diagnostic program executes on the image forming device. A list of available applets may be served to the computer, and one or more applets served in response to a user's selection from the list. A decision tree may be served, and one or more applets served as the user advances through the decision tree. Serving the diagnostic applets from the image forming device alleviates the need for a field repair technician to carry a large suite of diagnostic software to diagnose and repair a plurality of models, years, and configurations of image forming devices.
    • 图像形成装置包括网络服务器,并且向通信耦合的计算机提供小应用程序。 该小程序在计算机上执行,并且控制一个或多个操作和/或监视图像形成装置中的一个或多个条件或传感器。 作为在图像形成装置上执行的诊断程序,小程序可以向计算机用户提供详细的指令。 可以向计算机提供可用小程序的列表,并且响应于用户从列表中的选择而服务的一个或多个小程序。 可以提供决策树,并且用作用户的一个或多个小程序通过决策树进行。 从图像形成装置提供诊断小程序减轻了现场维修技术人员携带大量诊断软件来诊断和修复图像形成装置的多个型号,年数和配置的需要。

    • Methods and apparatus are provided for detecting a flameout of an operating turbomachine that is configured to receive a controlled flow of bleed air from a bleed air source and a controlled flow of fuel from a fuel source. A value of an operational parameter within the turbomachine is detected and a determination is made as to whether it has varied by a predetermined amount. If the operational parameter has varied by the predetermined amount, a flameout confirmation test is triggered. The flameout confirmation test includes holding the controlled flow of bleed air constant, commanding an increase in turbomachine speed, and confirming that a flameout has occurred by detecting that the controlled fuel flow to the turbomachine is at a maximum fuel flow limit and that actual turbomachine speed differs from the commanded turbomachine speed by a predetermined speed error.
    • 提供了用于检测操作涡轮机的熄火的方法和装置,其构造成从放气空间源和来自燃料源的受控流动的燃料中接收受控流出的空气。 检测涡轮机内的操作参数的值,并确定其是否变化了预定量。 如果操作参数变化了预定量,则触发熄火确认测试。 熄火确认测试包括保持受控的排气流量恒定,指示涡轮机速度的增加,并且通过检测到涡轮机的受控燃料流量处于最大燃料流量极限并确定实际的涡轮机速度来确认已经发生熄火 与指定的涡轮机速度相差预定的速度误差。
