Patents by Inventor Brad Lee Hollan

Brad Lee Hollan 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: 6640618
    Abstract: A method for detecting change in the foam forming characteristic of an input stream of an aqueous solution which continuously samples the input stream by taking a series of discrete, independent measurements. The method relies on an acoustic sensor to measure foam height within a column. A sample of the input stream is introduced into the column, and aerated to produce foam. The height of the column of foam is then measured using the acoustic sensor, which is correlated with the concentration of foam forming chemical.
    Type: Grant
    Filed: April 10, 2002
    Date of Patent: November 4, 2003
    Assignee: The United States of America as represented by the Secretary of the Navy

  • Patent number: 6405580
    Abstract: An apparatus for detecting change in the foam forming characteristic of an input stream of an aqueous solution which continuously samples the input stream by taking a series of discrete, independent measurements. A sample of the input stream is collected, analyzed, then discarded. The collect-analyze-discard cycle is repeated. The apparatus relies on an acoustic sensor to measure foam height within a column. This allows the column containing the foam to be fabricated from any material, including durable plastics. A sample of the input stream is introduced into the apparatus. The sample is then aerated by a aeration stone to produce foam. The height of the column of foam produced is then measured using the acoustic sensor. The sample is then discarded and the process repeated. The height of the foam column is correlated with the concentration of foam forming chemical.
