  • Publication number: 20240136775
    Abstract: A connector comprises a housing in a form of a bent tube. The housing includes a first tubular portion, a second tubular portion, and a bent portion connected between the first tubular portion and the second tubular portion. The first tubular portion and the second tubular portion extend at an angle of more than 0 degree and less than 180 degrees relative to each other. The housing is adapted to hold a cable extending through an interior thereof, wherein the cable is bent within the bent portion.

  • Patent number: 5726723
    Abstract: A sub-twisted nematic liquid crystal display (SBTN-LCD) device (30) having a liquid crystal layer (34) characterized as a polarization rotator below an optical threshold voltage, a half-wavelength plate at approximately a saturation voltage, and a transparent layer above the saturation voltage. The twist angle of the liquid crystal layer is between 46.degree.-89.degree., preferably about 55.degree.. The product of the birefringence of the liquid crystal and the thickness of the liquid crystal layer (.DELTA.nd) is in the range of 0.35-0.70 .mu.m, and preferably about 0.52 .mu.m for the 55.degree. twist. One polarizing layer (42) is applied to the liquid crystal device with the polarization direction either parallel or perpendicular to the immediately neighboring liquid crystal director. Further, the performance of the SBTN-LCD is dependent upon the parameters of the liquid crystal material, such as the elastic constants.
