Abstract: A laminated light guide and component carrier includes a polymeric material body having a first face. A light emitting diode is positioned on the first face. A connector is positioned on the first face. A through aperture is created in the body positioned proximate to the light emitting diode. A light guide of a light transmissive polymeric material is overmolded onto the light emitting diode and fills the through aperture and covers substantially all of the first face positioned outside of the space envelope containing the connector.

Abstract: A laminated printed circuit board with over-molded light guide includes a printed circuit board having electronic components mounted on a first face of the printed circuit board, and a bore extending through the printed circuit board. A light emitting diode is mounted on the first face proximate to the bore. An opaque film is fixed onto a second face of the printed circuit board, the opaque film creating an end wall of the bore. A light transmissive polymeric material is applied over each of the electronic components, the light emitting diode and a portion of the first face of the printed circuit board. A portion of the polymeric material extends into the bore and contacts the opaque film defining the end wall of the bore to create a light guide for transmitting light from the light emitting diode through the bore.

Abstract: A laminated light guide and component carrier includes a light guide of a light transmissive polymeric material. The light guide has a pocket in a first face. First electrical traces are printed on the first face. A light emitting diode is positioned in the pocket and supported on the light guide by attachment legs which extend outward from the pocket electrically connecting the light emitting diode to the first electrical traces. A light reflector is formed as a texturally modified area of the light guide directly aligned with the light emitting diode. A capacitive touch sensor is printed on a light guide second face and connected to second electrical traces defining capacitive touch traces printed on the second face. A window region of the light guide is defined where the capacitive touch sensor is aligned with the light reflector and the light emitting diode.

Abstract: A laminated light guide and component carrier includes a printed circuit board having a light emitting diode connected to a first face of the printed circuit board. A through bore is created in the printed circuit board proximate to the light emitting diode. An opaque film is applied using an adhesive to a second face of the printed circuit board oppositely directed with respect to the first face, the opaque film having a portion overlapping the through bore. A light guide is positioned within the opening and affixed to the portion of the opaque film overlapping the through bore. A white film is applied or ink printed onto the light guide without contacting the first face of the printed circuit board.

Abstract: A system for measuring phase attributes of high voltage electrical lines comprises a single high voltage probe. The probe comprises a sensing element for selectively measuring voltage of a high voltage electrical line. A processing circuit detects zero crossings of the measured voltage, applies a time tag to the zero crossings, and stores samples of the amplitude and time tagged zero crossings. A memory stores samples of the amplitude and time tagged zero crossings for a plurality of high voltage electrical lines. A processor is operatively associated with the memory for determining phase relationships between the plurality of high voltage electrical lines.
