Publication number: 20210212588Abstract: A wireless radio frequency triggered signal acquisition device includes three orthogonal pick up coils in which voltages will be induced by a time varying, spatially varying magnetic field inside a chamber of an MRI scanner. A radio frequency detection circuit detects radio frequency pulses emitted by an MRI scanner and a wireless transmission circuit transmits data from the device, A 3-axis magnetometer is used for measuring magnetic flux in the chamber of the MRI scanner. A processor uses the detected radio frequency pulses to synchronize measurements taken by the magnetometer and pick-up coils to a time frame of a gradient driver hardware, thereby matching the measurements to a pulse sequence waveform. The processor further combines measurements of induced voltages in the orthogonal pick up coils and the magnetic flux with the pulse sequence waveform in order to solve for the instantaneous position and orientation of the device.Type: ApplicationFiled: June 5, 2019Publication date: July 15, 2021Applicant: University of Cape TownInventor: Adam Marthinus Johannes van Niekerk

Patent number: 10591380Abstract: A method of estimating characteristics of new leaks formed in an isolated section of a water distribution system supplied through a pressure reducing valve. The pressure reducing valve is used to vary the pressure in the isolated section to at least two different pressure settings during a minimum night flow period at which the measured pressure and flow rate into the system are taken at each pressure setting. The leak characteristics are estimated by subtracting an estimated user consumption from the measured flow rate in each instance. The same measurements are repeated one or more days later. The estimated leak characteristics derived on a later date are compared with those derived on an earlier date to establish a difference in the estimated leak characteristics to determine if there is a new leak or leaks in the isolated section.Type: GrantFiled: October 17, 2017Date of Patent: March 17, 2020Assignee: University of Cape TownInventor: Jakobus Ernst Van Zyl
