Abstract: A server receives identification information for identifying an equipment and operating information of the equipment corresponding to a predetermined time, permitting a terminal device, if it is determined that the received operating information satisfies a predetermined condition, to refer to log information of the equipment accumulated in the server, the log information corresponding to the identification information corresponding to a time before the predetermined time, and not permitting the terminal device, if it is determined that the received operating information does not satisfy the predetermined condition, to refer to the log information of the equipment accumulated in the server. The predetermined condition is that the predetermined time is included in a predetermined standard period ending at a current time and the received operating information matches operating information included in the log information of the equipment corresponding to a time in the standard period and accumulated in the server.

Abstract: A data processing device for playing back a digital work reduces the processing load involved in verification by using only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on a DVD. In addition, the data processing device improves the accuracy of detecting unauthorized contents by randomly selecting a predetermined number of encrypted units every time the verification is performed.

Abstract: A diagnosis method includes giving an instruction to present at least two sound collection positions of an abnormal sound of an electric apparatus to an outside; comparing a current position of the diagnosis device and one sound collection position of the at least two sound collection positions; obtaining sound data indicative of an abnormal sound of the electric apparatus collected by a microphone, based on a comparison result and storing the sound data in a sound data storage portion so as be correlated with log data and the one sound collection position; and diagnosing an abnormal sound of the electric apparatus by using at least two items of sound data and at least two sound collection positions, based on a determination result whether sound collection is completed and a determination result whether diagnosis of an abnormal sound is possible.

Abstract: A diagnostic apparatus determines, for an element in a diagnostic element table, whether log information stored in a log storing unit satisfies a predetermined condition, the element indicating that a failure symptom can be diagnosed provided that the log information satisfies the predetermined condition, changes, based on a result of the determination, the element in the diagnostic element table to indicate the failure symptom can be diagnosed or cannot be diagnosed, the element originally indicating that the failure symptom can be diagnosed provided that the log information satisfies a predetermined condition, calculates a diagnostic priority of a plurality of operating conditions based on the statistical information and the changed diagnostic element table, and outputs information based on an operating condition, among a plurality of operating conditions, having the diagnostic priority satisfying the predetermined condition.
