  • Patent number: 11508086
    Abstract: Techniques are provided for image-based estimation of the orientation of an airborne platform. A methodology implementing the techniques according to an embodiment includes rotating an image, provided by a camera on the platform, by a selected rotation angle. The method also includes computing an intensity gradient image based on the rotated image. The method further includes extracting a left quarter segment and a right quarter segment of the intensity gradient image. The method further includes flipping one of the extracted segments about a vertical axis through that segment and comparing the non-flipped segment to the flipped segment to generate a matching score. The comparison may be based on a correlation between the flipped segment and the non-flipped segment. The process may be repeated for additional rotation angles and the rotation angle associated with the highest matching score is selected as the estimated orientation angle of the platform.

  • Patent number: 11509274
    Abstract: Techniques are provided for automatic gain control processing to reduce adverse effects associated with clipped samples resulting from conversion of analog signals to digital signals. A methodology according to an embodiment includes identifying a clipped sample of the digital signal, for example by comparison of the digitized sample values to a threshold value associated with a full scale value of the converter. The method also includes applying a window function to portions of the digital signal. The window function is configured to attenuate samples of the digital signal within a region centered on the identified clipped sample. A Hilbert finite impulse response (FIR) filter may be applied to the digital signal prior to applying the window function. Parameters of the window function are selected based on frequency response characteristics of the FIR filter and on signal to noise ratio requirements of an application that receives the windowed digital signal.

    Abstract: An energy harvesting system is disclosed that is especially well-suited for use on aerodynamic systems such as guided projectiles or other aerobodies. A series of piezoelectric cantilevers are arranged to capture vibrations from the ambient environment and transduce the mechanical motion from the vibrations into useful electrical energy. The piezoelectric cantilevers can be arranged along different planes from one another to capture different vibrational modes and directions. A power conditioning circuit is included to receive the electrical energy produced by the piezoelectric cantilevers. A storage element coupled to the power conditioning circuit is configured to store charge based on the electrical energy produced by the plurality of piezoelectric cantilever structures. The stored charge can be used to provide low levels of power to certain electrical components on board the aerodynamic system before it has been launched.
