Mark J. Lindsey has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Printing plate and method to prepare a printing plate
    Patent number: 6555205
    Abstract: A printing plate is prepared by the process comprising: (a) providing a substrate; and (b) applying by ink jetting to the substrate a fluid composition comprising a cationic polymer and an anionic polymer, in non-aqueous solvent. The ionic polymers interact and adhere to the substrate, so that after drying a durable printing plate is formed, without chemical development. The printing plate of this invention is capable of extended press run length and advantageously avoids the need of chemical development.
    Type: Grant

  • Orthogonal frequency hopping using skip zones
    Patent number: 6434184
    Abstract: The present invention is a method and apparatus for providing orthogonal frequency hopping for users in a communication system. The users have user bandwidths allocated on a frequency band. A jitter space is provided with a jitter bandwidth on the allocated frequency band. If at least one of the user bandwidths is larger than the jitter space, a skip zone is determined for at least one of the user bandwidths. The skip zone is unoccupied by a starting hop of the user bandwidths when the user bandwidths are shifted in a frequency hopping.

  • Printing plate and method to prepare a printing plate
    Patent number: 6359056
    Abstract: A printing plate is prepared by the process comprising: (a) providing a substrate; and (b) applying by ink jetting to the substrate a fluid composition comprising an acidic polymeric compound and a second compound comprising a pyridyl group in non-aqueous solvent, providing a printing plate that is ready-to-use on a press without having to develop it. The printing plate of this invention is capable of extended press run length and advantageously avoids the costly and time-consuming need of chemical development.

  • Reconfigurable, multi-user Viterbi decoder
    Patent number: 5151904
    Abstract: A decoding system for decoding a digital data stream that has been convolutionally encoded in accordance with a selected constraint length and selected polynomial codes, which system includes a processor, such as a Viterbi decoder, that is reconfigurable so that it can decode encoded digital data streams for a number of different user channels for which data streams have been convolutionally encoded in accordance with respectively different combinations of selected constraint length and selected polynomial codes.
