Provided is an information processing device capable of easily determining the number of times of charge/discharge of each of a plurality of secondary battery packs, the information processing device including a charge/discharge execution unit () having the following configuration. That is, the charge/discharge execution unit () determines the number of times of charge/discharge of each of a plurality of secondary battery packs () based on: the number of times a fully-charged state of the secondary battery pack is detected when the charge to the secondary battery pack is executed; the number of times an intermediate state in which the remaining capacity of the secondary battery pack becomes equal to a predetermined value between the maximum remaining capacity value in the fully-charged state and a remaining capacity of zero is detected when the discharge from the secondary battery pack is executed; and the number of times a remaining capacity near-zero state in which the remaining capacity of the secondary battery pack becomes equal to a near-zero value closer to the remaining capacity of zero than the predetermined value is detected when the discharge from the secondary battery pack is executed.

Information processing device

Disclosed are a method and an apparatus for identifying audio equipment plugs to be connected to a jack interface of an IT terminal including a common jack interface for a headphone, an earphone microphone and a stereo microphone and for automatically providing appropriate setup. An audio CODECis connected by way of an input/output selector circuitto a jack interfaceto which an audio equipment plugis to be connected. Also connected to the LEFT and RIGHT signal terminals of the jack interfaceis an R-V conversion circuit. The output voltages V-LEFTand V-RIGHTfrom the R-V conversion circuitare compared with a reference voltage by comparator circuitsfor controlling controllersof an input/output selector circuitand an audio CODECby the comparison outputs.

IT terminal and audio equipment identification method therefor

Using a 4-pin audio jack, 3-pin signal interfaces including the ground interface are assigned with conventionally used earphone/microphone functions (one microphone input and one speaker output), while the other interface corresponding to the fourth pin is assigned with a function of microphone input for voice recognition in high noise environment. This function is made effective only when a connected audio device requires such function.

Audio input/output device and method for switching input/output functions

All light-emitting devicestoare caused to emit lights, and the colored lights by light-emitting devicestoare radiated to two-dimensional barcodeto read barcode information only of a black pattern by CMOS imager. Information corresponding to this barcode information is displayed on display section. When a user selects information by using input sectionfrom among all the information, a light-emitting device corresponding to the selection is caused to emit a light, and a reading operation is performed.
