Eunhwa Jennifer Lenehan 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).

  • Full rate error detection circuit for use with external circuitry
    Patent number: 7042961
    Abstract: A system and method are provided for selecting an optimal threshold detection level for a single serial data input receiver. The method comprises: receiving a serial data stream of pseudorandom binary information; using a plurality of threshold detection levels, estimating bit values; comparing the differences between estimated bit values; and, adjusting the threshold levels to minimize the difference between comparisons of estimated bit values. In some aspects, comparing the differences between estimated bit values includes: counting a first number of differences between the first and third thresholds; counting a second number of differences between the second and third thresholds; and, adjusting the first and second thresholds until the first number equals the second number.
