  • Publication number: 20220299717
    Abstract: A contactless connector includes: a light emitter for emitting light; a light-transmitting member at least partially covering the light emitter; and an alignment mechanism that enables an alignment error between the light emitter and a light receiver on another contactless connector to be not greater than 5 microns; wherein the light-transmitting member includes a mating surface that is matched with an opposite surface of the another contactless connector and there is an elastic member on the opposite surface of the another contactless connector to adjust alignment of the alignment mechanism.

  • Patent number: 6922023
    Abstract: An inverter for driving multiple discharge lamps. The inverter has a transformer for driving a first discharge lamp and a second discharge lamp. The inverter also includes a first balancing circuit connected in series with the first discharge lamp and a second balancing circuit connected in series with the second discharge lamp. According to a matching signal, the first and the second balancing circuits adjust a first lamp current through the first discharge lamp and a second lamp current through the second discharge lamp, respectively. A comparator is provided to receive a first sensing signal from the first balancing circuit and a second sensing signal from the second balancing circuit. Comparing the first sensing signal with the second sensing signal, the comparator generates the matching signal which controls the first and the second balancing circuits to equalize the first lamp current and the second lamp current.

  • Publication number: 20020036560
    Abstract: A detachable transformer includes a high-voltage coil, an anti-splash cap, a low-voltage coil and a transformer body. The coupling chamber has a top end coupled to the anti-splash cap and a bottom end for matching the transformer body. It is assured that the filler can be encapsulated between the high-voltage coil and the transformer body. After the low-voltage coil and the iron core are inserted, the transformer is then formed. Furthermore, the anti-splash cap can be either separable from the coupling chamber or an integral part of the high-voltage coil. The anti-splash cap can also be replaced by an anti-splash sleeve, which is disposed in the high-voltage coil. This enhances the insulation effect of the high-voltage coil by encapsulating the filler in the gap and between the high-voltage coil and the transformer body.
