  • Patent number: 10659096
    Abstract: A method of performing a frequency scan at a radio includes placing the radio in an active mode and, while maintaining the radio in the active mode, for each of a plurality of target frequencies determining a coarse frequency tuning value based on the target frequency. The radio places a phase locked loop (PLL) in an open-loop configuration and while the PLL is in the open-loop configuration, programs the VCO with the coarse frequency tuning value. The radio programs the divider with a feedback adjustment based on the target frequency, places the PLL in a closed-loop configuration, and in response to the PLL reaching a settled state, performs an operation based on an output signal of the PLL.

    Abstract: Active areas of image sensors are determined by establishing a mergeline on a sensor map. Image data generated by active areas of image sensors are used to determine a seam or mergeline to create a panoramic image. The mergeline on a sensor map is implemented as an active image sensor area of addressable image sensor elements. An optimal mergeline is determined. Image sensor elements of the active sensor area of at least two image sensors are read and the read image data is stored on a memory preferably as contiguous data representing a panoramic image prior to demosaicing and displayed in real-time or close to real-time on a display.
