Information processing apparatus, information processing method and program

An authenticating system according to the present invention has a characteristic structure of which an authenticating sectionof a note type PCand an authenticating sectionof a batteryare directly connected through I/O portsand, respectively. Thus, the authenticating system according to the present invention can be relatively easily accomplished using a conventional system. The present invention can be applied to a system that is composed of a plurality of electronic devices that perform an authenticating process.

Communication system, authentication method, information processing device, information processing method, and battery

A battery pack includes: an obtaining unit for obtaining computation information for calculating a charge current including temperature information of a battery; a computation unit for computing a charge current for the battery based on the computation information; and a notification unit for notifying a computer of the charge current computed by the computation unit. The notification unit uses a dedicated command to notify the computer of the charge current. The battery pack includes: a storage unit for storing therein a first threshold value and a second threshold value relating to the temperature information, and the computation unit may compute the optimal charge current depending on which of ranges divided by the first threshold value and the second threshold value the temperature information belongs to.

Battery pack, information processing apparatus, charge control system, charge control method by battery pack, and charge control method by charge control system

An electronic apparatus is disclosed. The electronic apparatus includes a battery, a main body, a charging section, an obtaining section, and a controlling section. The battery has first information with which charging of the battery is controlled. The main body operates with the battery as a power supply. The charging section charges the battery. The obtaining section obtains the first information from the battery. The controlling section controls the charging section based on the obtained first information and causes the charging section to perform a charging according to another battery.

Electronic apparatus, charging method therefor, and battery

An information processing apparatus includes a hard disk drive, an acceleration sensor, and a determination section. The hard disk drive is capable of moving a head of the hard disk drive to a data-free landing zone. The acceleration sensor detects acceleration. The determination section obtains a low frequency component from the detected acceleration and determines whether it is necessary to move the head of the hard disk drive to the data-free landing zone based on the low frequency component.

Information processing apparatus having built-in hard disk drive and head retraction processing method of built-in hard disk drive

An information processing apparatus is disclosed. The information processing apparatus includes a hard disk drive, an acceleration sensor, a determination section, and a threshold value setup section. The hard disk drive is capable of retracting a head to a data-free landing zone. The acceleration sensor detects acceleration. The determination section obtains high frequency components from acceleration information detected by the acceleration sensor, obtains a vibration level corresponding to the obtained high frequency components, compares the vibration level with a threshold value which has been set up, and determines whether or not there is a necessity to retract the head of the hard disk drive to the data-free landing zone. The threshold value setup section allows a user to change the threshold value and set up the changed threshold value.
