Patents by Inventor Rowland Ellis

Rowland Ellis 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: 7992723
    Abstract: A filter includes filter media and a housing surrounding the media. The housing has an outlet and is sealed such that all fluid flow out of the outlet must first enter the cartridge and pass through the media. The housing has multiple inlet flow paths configured so that fluid impinging on the housing is diffused as it enters the cartridge and is prevented from flowing directly towards the filter media.
    Type: Grant
    Filed: October 25, 2007
    Date of Patent: August 9, 2011
    Assignee: PTI Technologies, Inc.
    Inventors: Michael S. Sandford, Kanwar Suri, Michael L. Gao, Rowland Ellis

  • Publication number: 20050228609
    Abstract: A sensor component that may be used in conjunction with a filter module may include a plurality of sensor packages. The latter, in turn, may incorporate one or more micro-electromechanical systems (MEMS) sensors to measure various characteristics of fluid flow and filtration. A single sensor component may be adapted to measure the pressure, temperature, flow rate, differential pressure, conductivity, viscosity, pH level, etc. of the fluid at an upstream and a downstream location. Sensor measurements may be obtained continuously in order to monitor and indicate fluid conditions, including the use of a warning mechanism to indicate an out-of-range condition when the measurements fall outside of pre-set limits. Depending on the application and the fluid being filtered, data, including measurement data, may be transmitted through electrical connections or wirelessly. In wireless configurations, a sleep-mode may be included to maximize the life of local power supplies.
