  • Patent number: 7305022
    Abstract: MIXR is implemented with a realistic amount of hardware even when the number of detected paths is large. From among path timings detected by a path searcher and MICTs generated based on the detected path timings, as many timings as there are fingers are selected by a timing selector and the selected timings are assigned to the fingers. When selecting the timings, the value of SNIR expected to be achieved by RAKE combining in a RAKE combiner, for example, is predicted by calculation from a received signal, and the path timing and MICT that maximize the SNIR are selected.

  • Patent number: 7241994
    Abstract: A digital probing type atomic force microscope (AFM) for measuring high aspect structures with high precision. A probe 21 is vibrated while moved to the vicinity of an atomic force region on a specimen surface. The position of the probe is measured when a specified atomic force is detected in the atomic force region. The probe is then moved away from the specimen surface. A servo system for maintaining a gap between the probe and specimen surface is stopped. The probe is moved to a measurement point along the specimen surface while kept away from the specimen. The vibration frequency is a frequency slightly offset from the cantilever resonance point. The atomic force is detected based on the vibration amplitude of the cantilever.
