  • Luminance control film
    Patent number: 6091547
    Abstract: The luminance control film includes a periodic array of optical structures which are small with respect to the wavelength of light. Scattering and diffractive effects result in improved off-axis illumination intensity in comparison with brightness enhancement optical devices having larger scale optical structures.

  • General purpose position control system having recursive profile generator
    Patent number: 5770829
    Abstract: The recursive profile generator of a general purpose position control system relies only upon current state and target state information in generating the path of movement for the armature of the servomotor. The profile generator employs a convergent algorithm for calculating the acceleration necessary to reach each control point or target position. By ignoring previous state information, the profile generator makes the use of reduced computing power possible and readily accommodates changing target state conditions.
