  • Patent number: 11228318
    Abstract: Exemplary aspects of the present disclosure involve a system and related method of PLL circuitry in a chirp signaling FMCW system having a variable PLL bandwidth (BW). To adjust the BW, the PLL circuitry may provide for variable capacitance in the circuitry. This capacitance change may allow for a bandwidth for one slope, as used for the acquisition period. The capacitance may then be adjusted to allow for a different bandwidth for another slope which is used to reset the circuitry in preparation for another frequency sweep. Adjusting the PLL BW, via variable capacitance, may be used to mitigate phase noise which can adversely the PLL.

  • Publication number: 20220012854
    Abstract: A system and method for correcting image distortion is provided. The system and method remaps pixel position of distorted images using a combination of radial distortion correction and tangential distortion correction lookup tables consuming less physical memory. The solution conserves both memory and memory access bandwidth. The radial distortion correction lookup table is formed by taking advantage of radial distortion being generally symmetric about a determined optical center of the camera lens. This symmetry allows for use of a quarter LUT for correction in all quadrants of a distorted image. In addition, tangential distortion can be corrected in a symmetric manner that saves memory space as well.

  • Patent number: 11224102
    Abstract: In a solid-state heating system, once a load with specific load characteristics has been placed in a heating cavity, a processing unit produces control signals that indicate an excitation signal frequency and one or more phase shifts, which constitute a combination of parameter values. Multiple microwave generation modules produce RF excitation signals characterized by the frequency and the phase shift(s). Multiple microwave energy radiators radiate, into the heating cavity, electromagnetic energy corresponding to RF excitation signals received from the microwave generation modules. Power detection circuitry takes reflected RF power measurements, and the processing unit determines a reflected power indication based on the measurements. The process is repeated for different combinations of the parameter values, and an acceptable combination of parameter values is determined and stored in a memory of the heating system.
