  • Patent number: 6178369
    Abstract: The present invention relates to a process and a control system for generating defined actuating forces in a brake which is electrically operable by way of an actuator, wherein there is a first static relation between the brake's actuating travel and the actuating force. The process and the control system permit determining the actuating forces which develop during operation without additional sensors. To achieve this object, according to the present invention, a second relation which corresponds to the operation of the brake is determined from the first relation and an information which represents the variations of the first relation.

  • Patent number: 6178281
    Abstract: A method for the manufacture of optical components, at least one three-dimensional optical waveguide structure being produced in a light-sensitive substrate by locally subjecting the substrate to an exposure so that a difference in refractive index between the substrate and the at least one optical waveguide structure is created. Provision is made for an exposure to occur at least twice, at different angles of incidence for the light perpendicular to a light wave propagation direction of the optical waveguide structure; the substrate surrounding what will later be the optical waveguide structure thereby experiences a diminution in refractive index, the optical waveguide structure being defined using a mask.

  • Patent number: 6174741
    Abstract: Improved techniques for quantifying proximity effects during fabrication of integrated circuits are disclosed. The improved techniques use active features formed on a semiconductor wafer to quantify proximity effects. According to the improved techniques, a device performance quantity for an active feature is measured, and then a feature length for the active feature is determined in accordance with the measured device performance quantity. The fabrication processing can then be evaluated and/or compensated based on the determined feature length. In one example, the active feature can be a metal-oxide semiconductor (MOS) transistor and the device performance quantity can be current.
