  • Patent number: 6733279
    Abstract: A remote micro-controlled oil lamp having a base with a crystal housing for a electrically activated wick is described. Mounted within the base is a coupled photodetector and audio circuit which respectively receives and transmits signals for lighting the wick and sounding a prerecorded message to signify an on and off condition. The wick is provided in the form of a pair of electrodes which are electrically activated via the photodetector by a remote laser source and/or a manual switch mounted within the base. When the lamp is either remotely or manually activated the electrodes generate a spark across a combustible fluid filled cylindrically shape gap as a catalyst to produce a candle light or flame. A micro-pump circuit is mounted within the base of the reservoir to ensure an adequate supply of fuel for an extended source of candle light.

  • Patent number: 5899685
    Abstract: A remote lighted wick extinguisher that uses a movement of air to extinguish the flame of a lighted wick. Energy is sent from a transmitter to a remote receiver. The receiver actuates a circuit, such as a mono-stable multivibrator or one shot producing a pulse. The pulse, having sufficient amplitude and duration, actuates a transducer, similar to a speaker. The pulse causes a diaphragm of the transducer to displace, thus displacing a volume of air. When the transducer is disposed in close proximity as the lighted wick, the displaced air is able to extinguish the flame of the lighted wick. Thus, a user is able to extinguish the flame of a lighted wick lamp remotely from a distance.
