    • The germ and noise filter device is a disposable, hand held filter apparatus that covers the mouth of the user during the exhale phase of a cough. The device comprises: a body with a cavity that houses three micro-filters; a corrugated tube; two one-way valves and a mesh screen. The body can be made of durable plastic material that may be transparent or a combination of many attractive colors. The two one-way valves act as a filter element for the noise that would normally occur. An eyelet is formed on the body to allow the device to be worn about the person. When a cough is eminent, the opening of the device is engaged against the user lips to prevent the transmission of air-borne diseases and reduce the noise of the coughs.

    • Systems and methods for auto-resetting span power protection are provided. In one embodiment, a method for deactivating a protective device is provided. The method comprises determining when an overload condition occurs on a communication medium; when the overload condition occurs, deactivating at least one protective device by applying, for a first predetermined period of time, a short-circuit to an output of a power supply that provides a holding current to the at least one protective device; and after the first predetermined period of time has elapsed, removing the short-circuit on the output of the power supply.
    • 提供自动复位功能保护的系统和方法。 在一个实施例中,提供了用于去激活保护装置的方法。 该方法包括确定何时在通信介质上发生过载状况; 当发生过载状况时,通过在第一预定时间段内施加短路至对至少一个保护装置提供保持电流的电源的输出而停用至少一个保护装置; 并且在第一预定时间段过去之后,消除电源的输出上的短路。

    • An improved circuit and method for increasing the stability of switch-mode power supplies via frequency fold-back is disclosed. For example, a circuit for increasing the stability of a switch-mode power supply using the compensation signal to control the frequency of the oscillator is disclosed, which includes an operational amplifier that functions to scale the compensation signal. Thus, the switching frequency of the power supply involved is decreased as the load is reduced. This novel use of the compensation signal to control the switching frequency of a switch-mode power supply significantly increases the stability of the power supply as compared to prior switch-mode power supplies. Therefore, the switch-mode power supply may be used for those applications where relatively high stability is desired.
    • 公开了一种用于通过频率折回来提高开关模式电源的稳定性的改进的电路和方法。 例如,公开了一种用于增加使用补偿信号来控制振荡器的频率的开关模式电源的稳定性的电路,其包括用于缩放补偿信号的运算放大器。 因此,随着负载的减小,所涉及的电源的开关频率降低。 与先前的开关模式电源相比,这种新颖的使用补偿信号来控制开关模式电源的开关频率显着增加了电源的稳定性。 因此,开关模式电源可以用于需要较高稳定性的那些应用。
