  • Patent number: 7506583
    Abstract: A system for exposing a flexographic printing plate with light includes a light-providing subsystem and a reflector around the light-providing subsystem. The reflector includes a body and a plurality of miniature mirrors on an interior of the body arranged to reflect light generated by the light-providing subsystem to exit the reflector at angles integrated between 0 degrees and a selected angle, such as 30 degrees. As a result, the shoulder angles of features on the flexographic printing plate are controlled within a selected range of angles, such as 0 to 30 degrees.

  • Publication number: 20050183597
    Abstract: An exposure system is provided that surrounds a photopolymer on a rotating cylinder ablation system. The exposure system linearly follows the ablation source and operates to expose the ablated (masked) plate with high intensity illumination from all sides so as to continuously expose all points on the photopolymer.

  • Patent number: 6700598
    Abstract: An apparatus utilizing non-coherent light digitally exposes a light-sensitive medium. The apparatus includes a non-coherent light source such as a wall stabilized plasma-filled capillary lamp, a reflector positioned proximate the non-coherent light source to reflect actinic radiation, a modulator positioned to selectively transmit the reflected actinic radiation and the light sensitive material positioned proximate the modulator to receive modulated actinic radiation.

  • Patent number: 6101403
    Abstract: An adapter and signal transmission cables for hands-free telephone system including a mobile telephone, car audio equipment such as a cassette recorder and a mobile telephone adapter. The mobile telephone adapter includes an adapter body, which can be pushed inside the cassette recorder; a hands-free microphone; a first signal transmission cable for connecting the adapter body and the mobile telephone; and a second signal transmission cable for connecting the hands-free microphone and the mobile telephone. The adapter body has a housing that resembles a cassette tape externally and a magnetic recording head installed inside. One end of the first and second signal transmission cables are joined together and connected to a plug, and the plug is capable of plugging into the voice input/output socket of the mobile telephone. When the mobile telephone picks up incoming voice signals, the signals will be transmitted via the adapter to the cassette recorder, which is then broadcast out through its loudspeakers.
