SYSTEM AND METHOD FOR REDUCING FALSE POSITIVE DETECTION BETWEEN A HUMAN AND A MOVING IMPLEMENT IN A POWER TOOL |
摘要 |
A method for detection of false positive condition that an object is in contact with an implement in a power tool includes sampling an electrical signal received from the implement, identifying in-phase and a quadrature components of the sampled electrical signal, identifying a magnitude of each of the samples with reference to the in-phase component and the quadrature component for the samples, detecting an object approaching the implement with reference to the plurality of samples, identifying a signal-to-noise ratio for the samples, and identifying a false positive condition for the detected object with reference to the identified signal-to-noise ratio for the identified samples. |
