Abstract: A digital multimeter can be monitored from a remote location via an on-board light source such as a backlight LED. The digital multimeter has memory, a processor operatively coupled to the memory, a light operatively coupled to the processor and the memory and a light sensitive sensor operatively coupled to the machinery and positioned proximate the light. The processor is configured to produce a first data signal containing information about the machinery, which is then modulated by the light so that the light blinks between an on state and an off state. The sensor is configured to detect the light on state and the light off state and convert the received light into a second data signal representative of the first data signal.

Abstract: A automated pilling, snag, and fuzziness inspection and grading method and apparatus for quantifying, locating, and sizing pills, snags, and/or fuzz on fabric rolls or fabric sample swatches, which includes a fulcrum about which the fabric is bent, the fulcrum defining an apex portion in the fabric where the fulcrum contacts the fabric. A moving mechanism is provided for moving a length of the fabric across the fulcrum causing the apex portion to be temporally redefined along the length of the moving fabric. An illumination mechanism is provided for projecting a light upon one side of the temporally redefined apex portion and a recording device is also provided for recording a horizon image of the temporally redefined apex portion where the horizon image being back lit by the illumination mechanism.
