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.

There is provided an information processing apparatus including an internal power source that supplies power, a power source information acquiring unit that acquires, from the internal power source, power source information relating to supply of the power in the internal power source, a drive status setting unit that determines power supply capability of the internal power source based on the power source information and sets setting information to define a drive status of a device in accordance with a determination result, and a device control unit that controls the drive status of one or more control subject device, based on the setting information.

Apparatus and method for controlling a drive status of a device based on power source information

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.

A personal computer receives a teletext signal. A television broadcast signal received by a TV tuner unit is converted to a composite video signal and a voice signal and are then supplied to a personal computer card. The personal computer card extracts character data with a character data extracting circuit when the input composite video signal is a teletext signal and converts such character data to the code data and supplies the code data to the personal computer for display on a liquid crystal display. Moreover, when the composite video signal is a television broadcast signal, it is converted to a digital signal with a video decoder and is then supplied to the personal computer for output to the liquid crystal display.
