Abstract
An apparatus for protecting a power tool user includes a glove or other garment having at least one sensor that monitors proximity to the power tool. Glove embodiments can include finger and/or thumb proximity sensors, and/or sensors that detect hand position, finger and/or wrist joint angle, vibration, and/or acceleration. Sensing targets can be retroactively installed on the power tool, and can define warning and/or danger zones. Sensing can be via magnetic, electromagnetic, capacitive, eddy current, and/or range finding means. Sizes of warning and/or target areas can be controlled by selecting targets from a plurality of targets of various detection ranges. Protective responses can vary according to different sensed events, and can include audible, visual, and/or tactile alerts, and/or interruption of power to the tool. Embodiments can record proximity and/or status data during a work session for review, training, and certification purposes. A controller can be physically cooperative with the garment.
