  • Patent number: 6904087
    Abstract: A method of adaptive multi-modulus equalization for an equalizer. A cost from a cost function is calculated according to a constant modulus algorithm (CMA). Equalizer coefficients are updated according to the cost, and modulus of each region is determined for a multi-modulus algorithm (MMA). The equalizer is switched to use the MMA when the cost reaches a first threshold. The MMA comprises several stages determined by thresholds, and the number of regions increases in every stage. The cost is calculated according to the MMA and modulus of each region. The equalizer coefficients are updated according to the cost, and modulus of each region is determined for the subsequent stage of the MMA. The equalizer is switched to the subsequent stage of the MMA when the MMA cost function output reaches the threshold corresponding to the current stage. The steps are repeated until the cost reaches a preset value. Then, the number of regions and equalizer coefficients are fixed to equalize the input signal.

  • Patent number: 6899484
    Abstract: A front cylinder and base are rotatably connected. Relative rotations cause stick-type cosmetic material retained by a core chuck member to slide forward and backward along an axial hole of the cylinder. Axially extending first slide grooves along an inner circumference of the hole have an inside diameter almost equal to a diameter of the material. Second grooves, deeper than the first, extend continuously from ends of the first grooves. Claws at a front-end section of the chuck retain the material and are slidably guided by the grooves. Back surfaces of the claws slide into contact with bottoms of the first grooves. Inner surfaces of the claws almost coincide with an inside diameter of the hole. If the material is loaded in the chuck with the claws at the second grooves, the claws elastically deform outward and the claws receive the material. With the claws at the first grooves, the claws tightly sandwich the material.
