  • Patent number: 8213407
    Abstract: One object of the present invention is to improve stability of wireless communication, regardless of a movement speed of a mobile station by estimating a movement speed of a mobile station using a signal prepared in advance for a used standard and selecting an appropriate base station. In the wireless communication system 100 according to the present invention, in order to adjust a timing of receiving data from the PHS terminal 110 to a desired timing, base stations 120, 122 transmit an adjustment signal for advancing or delaying data transmission timing in the PHS terminal 110. Thus, the PHS terminal 110 calculates a bias amount of such an adjustment signal to determine high speed movement of the PHS terminal 110 and perform handover from a micro cell base station 120 to a macro cell base station 122.

  • Patent number: 8032783
    Abstract: The service life of memory cards is to be substantially elongated against the occurrence of faulty blocks. A control logic searches blocks in a nonvolatile memory cell array for any acquired fault on the basis of a fault-inviting code in a management information section. If any faulty block is detected, the faulty block will be subjected to write/read comparison of data to judge whether or not the data in the block are normal. Any block determined to be normal will undergo rewriting of its fault-inviting code and registered as a normal block. Further, the registered block is stored into a write management table in the management area as a writable block. This enables an essentially normal block judged faulty on account of an erratic error or some other reason to be restored.
