  • Ultrasonic Flow Metering
    Publication number: 20230324209
    Abstract: Embodiments include a novel, easy to install, non-intrusive, ultrasonic water flow meter with a self-calibrating three-piezoelectric transducer configuration attached externally to a water pipe, that allows for accurate measurement of water flow, and can provide the flow data to a remote system for billing and further analysis. The water flow data can further be analyzed for water consumption by individual fixtures, in support of conservation and usage management efforts.

  • Method for geo-location interpolation and compression
    Publication number: 20020002053
    Abstract: A system and method for efficiently transmitting geographical location data of mobile units is disclosed. The invention allows less than the complete geographical location data to be transmitted and reported to a locater. Using fixed geographical references, the locater then interpolates the complete geographical location of mobile units from the reported data.
