  • Patent number: 7414540
    Abstract: In one preferred embodiment, a power indicator circuit for a computer comprises a light-emitting diode (LED) indicating power management states of a computer; a first resister connected between one pole of the LED and a power source; a second resistor connected between the other pole of the LED and a power source, a first branch circuit connected between the one pole and ground; and a second branch circuit connected between the other pole and ground. Wherein the first resistor and the second resistor control a current through the LED. Because the LED emits lights of different colors or turns off according to the different power management states, it is easy for users to see what the power management state of the computer is.

  • Patent number: 7218057
    Abstract: A Style B PAPI system comprises a plurality of identical lamp housing assemblies, each with one or more lamps and each housing assembly including: an electronic bypass circuit with first and second oppositely poled SCRs coupled across the terminals of each lamp; a zener diode; and a diode bridge for developing a first trigger voltage across the zener diode in the event of failure of a lamp. The first trigger voltage causes alternate conduction in the first and second SCRs from the AC voltage developed across the failed lamp. A lamp control circuit includes a third SCR that is coupled across the zener diode for developing a second trigger voltage for similarly driving the SCRs. The lamp control circuit is operated by a microcontroller-controlled common lamp control circuit that activates all of the lamp control circuits and disable all of the lamps in response to a tilt condition for the lamp housing assembly.
