Babak Abbasi Bastami 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).

  • Publication number: 20220113217
    Abstract: A system for determining a location of an egress point in a plumbing system that includes a branched system of pipes within a building is provided. The system includes a first sensor that is configured to measure a first pressure signal as a function of time at a first location within the plumbing system, and a second sensor that is configured to measure a second pressure signal as a function of time at a second location within the plumbing system. The plumbing system includes multiple branch points between the first location and the second location. The system also includes a processor that is configured to determine a temporal difference between a first pressure drop in the first pressure signal and a second pressure drop in the second pressure signal, and use the temporal difference to determine an estimated location of the egress point in the plumbing system.

  • Publication number: 20190250064
    Abstract: A method of identifying a type of plumbing system of a building is provided. The method includes determining a spectral energy ratio as a function of first pressure data acquired during a first time period in which a water flow through a plumbing system of a building is below a threshold. The method also includes determining a multimodal test value as a function of second pressure data acquired during a second time period that includes at least some time during which the water flow through the plumbing system is greater than or equal to the threshold. Further, the method includes identifying a type of the plumbing system of the building as a function of the spectral energy ratio and the multimodal test value.
