  • Publication number: 20080281520
    Abstract: In a positioning system, an arithmetic processor analyzes positioning data acquired by a receiving terminal and determines a positioning target location. Upon reception of positioning data, the arithmetic processor accumulates the positioning data on analysis data stored in a storage section prior to the reception, stores an accumulated data as new analysis data, and transmits an analysis result to the receiving terminal. The receiving terminal transmits positioning data, acquired for a predetermined time, to the arithmetic processor and continues to acquire positioning data. Upon reception of the analysis result, the receiving terminal determines whether the analysis result is good or poor. When the analysis result is poor and the positioning data is stored for the predetermined time from a last transmission of the positioning data, the receiving terminal transmits the positioning data to the arithmetic processor and continues to acquire positioning data.

    Abstract: An update client sends to an update server which is connected to the update client via a communication line, identification information of a driver and firmware which are included in a disk array system, and identification information of an error event which has occurred in the disk array system. The update server determines whether update of the driver and the firmware is necessary or not in accordance with a combination of the supplied identification information of the driver, the firmware, and the error event. In a case where it is determined that update is necessary, the update server sends to the update client, update data corresponding to the combination of the supplied identification information of the driver, the firmware, and the error event. The update client updates both of the driver and the firmware using the supplied update data.
