摘要： A method and device for detecting and/or photographing unregulated light flash events such as lighting strikes and muzzle flashes during both daylight and night time conditions is disclosed. The present device utilizes a photodiode sensor in conjunction with a photoresistor to control feedback gain of a transimpedance amplifier thereby providing non-linear amplification and therein constant sensitivity to detect an unregulated, omni-directional flash of light and produce an output signal that is input to an analog comparator circuit whereat a predetermined threshold level is set to prevent false triggering of the isolation relays and/or camera shutter. The output from the comparator circuit is input to a timer circuit to produce a signal of sufficient duration to trigger the isolation relay(s) and/or camera shutter. The output signal from the timer circuit is sent to an isolation relays and/or an infrared coded pulse generator depending on the features of the particular associated equipment in order to release the camera shutter or to protect an electronic or electrical device from the damaging effects of the lightning return stroke. In an alternative embodiment the functions of the comparator circuit, the timer circuit and the coded pulse generator are carried out by a programmable logic device such as a mixed signal processor with analog, digital, real time clock and non-volatile RAM capability wherein the lightning event processing functions are incorporated into the program code. In a further embodiment, the coupling circuit is tuned wherein motion of an object is detected. In yet a further embodiment, multiple photosensor arrays are utilized in conjunction with non-linear amplification and computing means to determine the location of flash events and to control associated equipment.

摘要： A thermally conductive wedgelock having improved thermal conductivity is used to secure a circuit card assembly in a card guide slot formed in a housing of an electronics package. The circuit card assembly has a thermal mounting plate that is used to secure the assembly in the slot. The thermally conductive wedgelock secures the circuit card assembly in the housing and conductively couples heat from the circuit card assembly to the housing by way of the card guide slot. The wedgelock provides a secondary heat path to the card guide slot to housing in addition to the primary heat path through the thermal mounting plate. Apparatus is provide for expanding the wedgelock in the card guide slot to secure the circuit card assembly therein. The thermally conductive wedgelock may be made of copper or other metal having high thermal conductivity. The wedgelock preferably comprises two tapered wedges, and has a guide that prevents rotation between the adjacent wedges.

摘要： A method and device for detecting and photographing unregulated light flash events such as lighting strikes during both daylight and night time conditions is disclosed by detecting the initiation of the lightning stepped leader event of the immediate lightning flash for photographic and detecting activities. The present device utilizes a photodiode sensor in conjunction with a photoresistor to control feedback gain of a transimpedance amplifier to detect an unregulated, omni-directional flash of light and produces an output signal that is input to an analog comparator circuit where a predetermined threshold level is set to prevent false triggering of the isolation relay(s) and/or camera shutter. The output from the comparator circuit is input to a timer circuit to produce a signal of sufficient duration to trigger the isolation relay(s) and/or camera shutter. The output signal from the timer circuit is sent to isolation relays and/or an infrared coded pulse generator depending on the features of the particular camera in order to release the camera shutter or to protect an electronic or electrical device from the damaging effects of the lightning return stroke. In an alternative embodiment the functions of the comparator circuit, the timer circuit and the coded pulse generator are carried out by a programmable logic device such as a mixed signal processor with analog, digital, real time clock and non-volatile RAM capability wherein the lightning event processing functions are incorporated into the program code. The device circuitry is incorporated into a compact enclosure which can be mounted directly onto the camera or, or in the alternative integrated into the camera housing.
