  • 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.

  • Patent number: 6150765
    Abstract: A signaling lamp flasher generates audible sound while controlling intermittent contact between a vehicle power source and a signaling lamp. A flash control device generates the intermittent contact, and is preferably an input relay disposed between the power source and the signaling lamp. An IC-based audible flash circuit generates a control pulse in response to the voltage pulse from the power source, generates a buzzer pulse in response to the control pulse, and generates audible sound in response to the buzzer pulse. The signaling lamp flasher also provides current overload protection at the signaling lamp through a pop-out resettable fuse. The location and ability of the fuse to be reset provides improved dependability and serviceability.
