  • Patent number: 9329719
    Abstract: A hybrid touch-screen display that integrates force-based touch-screen technology with any one from among a group of projective capacitive, surface capacitive, resistive, digital resistive, SAW, IR, APR, DST, optical and electromagnetic touch-screen technologies to provide an ability to compensate for non-perfect force transfer. An alternate implementation is also disclosed that employs a single force sensor for relative force measurement in a system in which force is traditionally not measured, here a water dispenser unit. This allows compensation for varying static loads, run-time calibration, and filtering of extraneous loads through firmware.
