According to an embodiment, a client includes a street information collection unit for collecting street information near an arrangement place, a provision determination unit for determining whether the street information collected by the street information collection unit is information required to be provided to the server, and a first transmission unit for transmitting the street information, which is determined to be required to be provided by determination of the provision determination unit, to the server, with client identification information for identifying the client.

Street information processing system, client and server applied to street information processing system, and method and program of the same

A switching regulator includes an inverter circuit and a size adjustment circuit. The inverter circuit converts an input voltage into an output voltage by a switching operation of a switch circuit. The size adjustment circuit controls an ON resistance of the switch circuit, depending on a power efficiency that is calculated from an input power dependent on the input voltage and an output power dependent on the output voltage.
