Patents by Inventor Philip H. Gerard

Philip H. Gerard 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: 8130370
    Abstract: Methods and systems for analyzing optical parameters of a selected optical fiber member are disclosed. A signal input from an optical fiber member may be selected by instructing a corresponding optical separation device. The output from the corresponding optical separation device may be combined with the outputs of other optical separation devices using an optical coupler. A measurement circuit may measure the optical parameter from the output. Proper operation of an optical separation device may be validated by a monitoring circuit. The monitoring circuit may provide an indication to a user or may be processed by a diagnostic processor. A processing circuit may select one of the optical separation devices in order to measure the optical parameter for a corresponding optical fiber member and consequently may instruct an adjustment circuit to cause the selected optical fiber member to conform to a desired value of the optical parameter.

  • Patent number: 7372554
    Abstract: The present invention provides methods and apparatuses for analyzing optical parameters of a selected optical fiber member. A signal input from an optical fiber member is selected by instructing a corresponding optical separation device. The output from the corresponding optical separation device is combined with the outputs of other optical separation devices using an optical coupler. A common measurement circuit measures the optical parameter from the output. Proper operation of an optical separation device is validated by a monitoring circuit. The monitoring circuit may provide an indication to a user or may be processed by a diagnostic processor. A processing circuit selects one of the optical separation devices in order to measure the optical parameter for a corresponding optical fiber member and consequently instructs an adjustment circuit to cause the selected optical fiber member to conform to a desired value of the optical parameter.
