    摘要: A power control method for a magnetic disk unit is disclosed. The method includes identifying a type of a last instruction sent to a magnetic disk unit and, in response to identifying the type, setting a wait time that varies according to the type. In response to the wait time having elapsed after a completion of processing ordered by the last instruction, an idle instruction is sent to the magnetic disk unit for placing the magnetic disk unit in an idle state in which power consumption is reduced.

    摘要: A method to reduce the power dissipation of a system by omitting an unnecessary CPU throttling operation in a power management apparatus that performs the CPU throttling operation. A power management apparatus 10 is constituted by an event detecting section 12 to detect an event in a system, an activity detecting section 14 to decide whether the system is in a busy state or in an idle state by checking whether or not there is activity in the system, and a clock control section 16 to execute CPU-clock control. The control section 16 does not perform an unnecessary CPU throttling operation, by stopping the CPU throttling operation when the system is in the idle state and performing the CPU throttling operation only when the system is in the busy state. With this, the power dissipation of the system can be considerably reduced.

    摘要: A battery pack is disclosed. The battery pack includes a battery, an impact sensor, a processor and a memory. The impact sensor is capable of generating an impact signal in response to a detection of an impact on the battery pack. The processor is capable of generating impact information based on the impact signal, and processor continues to count a number of charging times to the battery after the generation of the impact information. The memory is capable of storing the impact information and the number of charging times. The processor can refer to the memory to deliver a control command to a battery charger so that the battery can only be charged up to an allowable charge capacity smaller than a full charge capacity after an occurrence of an impact when the battery pack is attached to the battery charger. The charging to the battery stops when the number of the counted charging times reaches a predetermined number of allowable charging times that is allowed after the generation of the impact information.

    摘要: A light detecting apparatus has a two-axis deflector such as a two-axis mirror capable of controlling the deflection of a light beam. The apparatus realizes a sure and speedy light beam search operation without increasing deflecting frequencies of the two-axis deflector. In the light detecting apparatus, a digital signal processor (3) generates two periodic signals having different frequencies to separately control deflective operations in two axial directions of the two-axis deflection mirror (1). A light beam from the two-axis deflection mirror (1) draws a locus on a two-dimensional position sensitive detector (2). Along the locus, the search operation is carried out to find an orientation of a light emitting element that emits a light beam toward the two-axis deflection mirror (1).

    摘要: A communication route guidance system provides exchange of data between an information center and each of a plurality of mobile units such as vehicles. The information center has the latest road data and searches it to prepare recommended route guidance data in response to a request from the mobile unit. The reccommended route guidance data is divided into a plurality of data segments, each usable as an independent guidance instruction in the mobile unit. The mobile unit has stored therein road data similar to the road data in the information center and determines if data communication with the information center is available. In a case where the mobile unit can not communicate with the information center, the mobile unit prepares route guidance based on the road data stored in the mobile unit. It thereby becomes possible to guide the user even in the case that the mobile unit can not communicate with the information center. Even in a case where a communication link is disrupted during transmission of route guidance data to the mobile unit, the mobile unit can effectively prepare whole route guidance data in combination with already-received route guidance data and additionally prepared route guidance data by reference to the road data stored in the mobile unit because the already received route guidance data is structured to be usable independently.
