Alan B. Arehart 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).

  • Patent number: 9582447
    Abstract: A switch configured to enforce MIL-STD-1553B communication protocol is provided. The protocol is a request-response protocol allowing a bus controller to send a request and a remote terminal to send a response. In one embodiment, the switch is configured to isolate communication between a bus controller and each remote terminal by blocking non-compliant communications issued from any remote terminal. The switch may also isolate communication preventing a first remote terminal from receiving communication from a second remote terminal when the communication is not addressed to the first remote terminal. In another embodiment, a system provides isolation for bus controller to remote terminal communications by using one-to-one pairings of bus controller terminals to remote terminals. The switch may select a particular bus-controller-terminal-to-remote-terminal pairing from amongst a plurality of bus-controller-terminal-to-remote-terminal pairings.

  • Publication number: 20040117130
    Abstract: A system and method for improving the accuracy of DNA sequencing and error probability estimation through application of a mathematical model to the analysis of electropherograms. The method includes processing a plurality of information obtained from a base calling system and creating a plurality of refined base calls using a plurality of original base calls and a plurality of intrinsic peak characteristics. A quality value is also assigned to each of the plurality of refined base calls using the plurality of intrinsic peak characteristics. Processing comprises detecting a plurality of peaks, expanding the plurality of peaks, and resolving the plurality of expanded peaks. Resolving may include fitting the plurality of expanded peaks using a model of a peak shape. A peak resolution parameter is calculated and used in processing. The system may also be trained.
