A communication apparatus includes a wireless module configured to execute communication with a communication terminal; a host system including a communication controller configured to control the communication with the communication terminal executed by the wireless module; an updater configured to update information used for the communication, at predetermined updating timings; and an operation status controller configured to control an operation state. The communication apparatus further includes a sub-system configured to send, to the operation status controller, a report indicating that an updating time period has elapsed from the updating timing of the information. The operation status controller causes the host system to return to a regular mode, upon receiving the report indicating that the updating time period has elapsed while the host system is in an energy saving mode.

Communication apparatus, communication terminal, and communication system

An information processing apparatus includes: a communication unit configured to perform communication with a short-distance wireless communication tag; a display control unit configured to display position information of the communication unit on a display unit; and a first determining unit configured to determine whether an establishing signal for establishing the communication is received from the short-distance wireless communication tag. The communication unit performs the communication with the short-distance wireless communication tag in response to the first determining unit determining that the establishing signal is received.

Information processing apparatus and recording medium

According to an embodiment, provided is an electronic device that includes: an energy generation unit that generates electrical power; an accumulating unit that accumulates therein the electrical power generated by the energy generation unit; and a network control unit that includes: a first function unit that performs network response processing; a second function unit that performs network response processing with a relatively smaller processing load than the network response processing performed by the first function unit; and a third function unit that controls the electrical power supply to the function units. The third function unit stops the electrical power supply to the first function unit in a predetermined standby operation mode that is standby for a network response request, and supplies the electrical power to the second function unit directly from the energy generation unit bypassing the accumulating unit.

Electronic device, image processing apparatus, and device control method

An information processing device connected to a terminal via a network includes a memory that stores inquiry packet data received from the terminal in association with response packet data to respond to the inquiry packet data; control circuitry to control an operation mode of the information processing device, wherein when the information processing device is in an energy conservation mode, the control circuitry determines whether or not the received inquiry packet data is new inquiry packet data determined by new network protocols, when the received inquiry packet data is the new inquiry packet data, the control circuitry reinstates the information processing device, in conjunction with a transmission for the response packet data generated by the information processing device to the terminal, and stores the received inquiry packet data and the generated response packet data to the memory.

Information processing device, method, and information processing system

An electronic device includes a power generation device that generates electricity, a charging battery that charges electricity, and a power supply device that receives power supply from the outside power source. The electronic device selects at least one of the power generation device, the charging battery, and the power supply device as a power supply source to supply electric power to each unit of the electronic device that is operating, based on an operating state of the electronic device or operation being performed by the electronic device.
