  • Capacitive measurement processing for mode changes
    Patent number: 9746975
    Abstract: Hybrid detection includes determining a first profiles based on multiple capacitive measurements, segmenting the first profiles into one dimensional intervals to obtain multiple segments, determining multiple regions of interest using the segments, and determining a set of contiguous regions based on multiple mutual capacitive measurements. Hybrid detection further includes selecting, from the set of contiguous regions, a set of valid contiguous regions using the regions of interest, and reporting positional information for each contiguous region in the set of valid contiguous regions.
    Type: Grant
