    • The present invention provides a circuit and a method for preheating filaments and a ballast. The circuit for preheating filaments includes: a transistor; a first winding, one terminal of which being electrically connected with a collector of the transistor, and the other terminal being connected to an input of a power source; a second winding, one terminal of which being electrically connected with an emitter of the transistor, the other terminal being electrically connected with a base of the transistor, and the second winding being coupled with the first winding in a self-excitation mode; one or more load windings respectively connected with the filaments in series, and each of which being coupled with the first winding in a flyback mode; and a delay switch, which changes into an on state from an off state when a trigger signal with a predetermined delay is received, so as to turn off the transistor. There is also provided a method for preheating filaments and a ballast. The circuit for preheating filaments may save energy consumption and the cost is low.

    • Methods and devices are provided for controlling the brightness of a display 12 for an electronic device 10 based on ambient light conditions. In one embodiment, an electronic device 10 may employ one or more brightness adjustment profiles 62, 130 that define response rates for changing brightness levels based on ambient light levels. The response rates may vary depending on the magnitude and/or direction of change in the ambient light levels. In certain embodiments, the response rates may be designed to approximate the physical response of the human vision system. Further, in certain embodiments, noise reduction techniques may be employed by adjusting the response rates based on the magnitude of the change in the ambient light level and/or based on whether the display is operating at steady state or executing a brightness adjustment.
    • 提供了用于基于环境光条件控制电子设备10的显示器12的亮度的方法和装置。 在一个实施例中,电子设备10可以采用一个或多个亮度调整简档62,130,其基于环境光水平来定义用于改变亮度水平的响应速率。 响应率可以根据环境光水平的变化的大小和/或方向而变化。 在某些实施例中,响应速率可被设计为近似人类视觉系统的物理响应。 此外,在某些实施例中,可以通过基于环境光级别的变化的大小和/或基于显示器是处于稳定状态还是执行亮度调整来调整响应速率来采用降噪技术。
