  • Operator controlled electrical output signal device with variable feel and hold feedback and automated calibration and learnable performance optimization
    Patent number: 10942540
    Abstract: An output signal device and method that provides the operator force feedback similar to a pilot control joystick. These force feedback regions include free play, dead-band start of modulation, modulation, fore-warning bumper and hold near max angle. This output signal device may also vary the fore-warning feel and hold positions to be at any angle. This output signal device uses force sensing as the signal and has force slope changes used as auto-calibration of the output signal. This improves signal accuracy and provides a service prognostic signal. The prognostic signal may be used to activate redundant sensor. The variable force feedback may improve operation on rough terrain. The force feedback, may allow more productive operating positions to be learned. This enables productivity and other important job site criteria such as fuel usage to be optimized by interactive communication with this output signal device.
