  • Patent number: 5757436
    Abstract: An image-processor system for compensating for accumulated phase-and-gain errors incurred during transmission of a video signal over a communications channel. The image-processor system comprises an initial-video processor, an input-video processor, a feature-video processor, a frame buffer, an RGB-output processor, an output-video processor, and a control processor. The initial-video processor generates a composite video signal. The input-video processor converts the composite video signal into digital-component signal information. The feature-video processor processes the digital-component signal information as processed component video information. The frame buffer re-establishes broadcast timing standards in the processed component video information to generate time-base corrected digital information. The RGB-output processor decodes the time-base corrected digital information into RGB analog and digital outputs. The analog RGB outputs are output directly.

  • Patent number: 5077794
    Abstract: A dual-framing-bit-alignment apparatus having a communications channel, a data device, an encryptor, a framing-bit device, a decryptor, a first framing-bit repositioner, and a second framing-bit repositioner. The first data device generates a first data-bit sequence having a first framing-bit sequence. The encryptor encrypts the first data-bit sequence as an encrypted-bit sequence. The framing-bit device substitutes on the encrypted-bit sequence, a second framing-bit sequence, thereby generating a framed-encrypted-bit sequence. The decryptor decrypts the framed-encryped-bit sequence as a second data-bit sequence. The second data-bit sequence contains errors due to the second framing-bit sequence. A second framing-bit repositioner detects in the second data-bit sequence, the first framing-bit sequence and the errors. In response to detecting the errors and the first framing-bit sequence, the first framing-bit repositioner aligns the first framing-bit sequence with the second framing-bit sequence.

  • Patent number: 5056107
    Abstract: A radio communications network for transmitting data from a plurality of remote stations to a central station is provided. This system is particularly proposed for automatic meter reading systems in which the remote stations are located at utility meters. The system includes an array of receiving stations arranged relative to the remote stations so that the mesages from each remote station can be received by at least two and preferably four of the receiving stations providing a high level of duplication of messages. The remote stations transmit utility usage information obtained from the previous time period at a random time subsequent to the time period so that message collisions can occur. High level of duplication provided by the increased number of receiving stations reduces the message loss. A quiet period during which the remote stations are prevented from transmitting can be used for communication between the receiving stations and the central station.
