  • Patent number: 6270176
    Abstract: The invention provides an exemplary label printer and methods for printing labels on optical media. According to one exemplary method, an optical medium is inserted into a printing device having a mechanism for rotating the optical medium. The optical medium is rotated with a rotation mechanism. Further, a print head is moved over the optical medium and ink is ejected onto the medium while the medium is rotating to create a label on the medium.

  • Patent number: 5518325
    Abstract: A method and system for individually labelling a recording medium at the time that digital information is recorded thereon is provided. The method provides for transferring at least a portion of the digital information in the form of a digital data stream to the medium from a storage location. Title information is extracted from the data stream and used to create a visual label that is placed on the recording medium. The title information on the recording medium uniquely identifies the digital information that is recorded on the medium. In an exemplary embodiment, the system of the invention will use a controller to receive a portion of the digital data stream stored in the storage location. A recorder is in communication with the controller for receiving the data stream from the controller and for recording the data stream on the recording medium.

  • Patent number: 5270576
    Abstract: The invention provides an electrical connector network for coordinately controlling multiple electrical appliances connected to the network. The network comprises a control outlet connected to an electrical power inlet, at least one slave outlet, and means responsive to current flow to the control outlet for selectively connecting the slave outlets to the power inlet, whereby power is available at the slave outlets only when current flows through the control outlet. In a preferred embodiment, the invention includes a current transformer for sensing current to the control outlet, the transformer producing a secondary current which is conditioned by an amplifier to drive a power triac, actuating a relay controlling power to the slave outlets. The connector network may be embodied in various structures, including extension cords, power strips, wall outlets or electrical appliances.
