  • Network Clock Synchronization Using Total-Field Magnetometers And The Spatial Coherence Of The Earth's Geomagnetic Field | TechLink
    in learning more about this patent and related research and licensing opportunities please contact any of our Tech Managers at http techlinkcenter org about staff Patent Identifier 8954608 Status Active Categories Electronics A method for synchronizing network clocks comprising the following steps measuring with a first magnetometer the geomagnetic field at a first network node processing data measured by the first magnetometer to generate first sensor spatially coherent data measuring with a second total field magnetometer the Earth s magnetic field at a second network node wherein the second magnetometer is physically separated from the first magnetometer by a distance of up to one kilometer processing data measured by the second magnetometer to generate second sensor spatially coherent data transmitting the first sensor spatially coherent data from the first network node to the second network node calculating a clock drift between the first and second network nodes based on the first sensor spatially coherent data and the second sensor spatially coherent data and adjusting the second node system clock to match the first node system clock based on the calculated clock drift USPTO url http patft uspto gov netacgi nph Parser patentnumber 8954608 Facebook Twitter Google Plus LinkedIn Main menu

  • Auto-Focus For Circular Synthetic Aperture Sonar | TechLink
    this patent and related research and licensing opportunities please contact any of our Tech Managers at http techlinkcenter org about staff Patent Identifier 8937849 Status Active Categories Electronics A method of focusing fully coherent circular synthetic aperture sonar CSAS imagery is provided A k space representation of the CSAS image is generated using the two dimensional Fast Fourier Transform FFT Sub aperture images are generated by windowing the k space representation and applying the two dimensional inverse FFT to the windowed spectrum All adjacent complex sub aperture images are correlated the correlation peaks are detected and the relative shifts in X and Y as a function of look angle are recorded The relative shifts between adjacent sub apertures are integrated and the means are subtracted to find the absolute shift as a function of look angle A motion solution is calculated by exploiting the relationship between apparent scene shift and actual vehicle sway The motion estimation is used to generate a phase correction matrix that is multiplied by the k space representation of the fully coherent image USPTO url http patft uspto gov netacgi nph Parser patentnumber 8937849 Facebook Twitter Google Plus LinkedIn Main menu Home Licensing Joint R D
