A communication apparatus includes a communication interface configured to communicate with a plurality of communication devices on a network, a memory that stores setting data in which a plurality of different types of communication conditions are associated with each other, a display, and a processor configured to search the network for connectable communication devices, control the display to display a first screen indicating one or more of the communication devices that satisfy the communication conditions, and upon selection of a communication device through the first screen, determine the selected communication device as a communication target of the communication apparatus.

Communication apparatus, communication target determination method in communication apparatus, and image forming device

An image forming apparatus communicates with another device and includes a processor that controls the communication. A control unit controls the apparatus to operate in one of at least a first power saving state, a second power saving state, and a normal state. In the first power saving state, the apparatus is controlled so that an image forming unit, an image reading unit, and the control unit are not activated, and a communication device is activated. In the second power saving state, the apparatus is controlled so that at least one of the image forming unit and the image reading unit are not activated, and the communication device and the control unit are activated. In the normal state, the apparatus is controlled so that at least the image forming unit, the image reading unit, the communication device, and the control unit are activated.

Image forming apparatus and control method

According to one embodiment, a wireless communication apparatus includes a communication interface and a processor. The communication interface performs wireless communication with other wireless communication apparatuses and a client giving an instruction for an operation. The processor switches a power state of the communication interface and the other wireless communication apparatus based on information regarding validation and invalidation of wireless communication functions, simultaneous connection numbers, and connectable numbers of the other wireless communication apparatuses.

Wireless communication apparatus, image forming apparatus, and method of controlling image forming apparatus

An image forming apparatus includes a short-range wireless communication device to communicate with a portable terminal via short-range wireless communication, a first wireless communication device to communicate with the portable terminal via a direct wireless connection, a second wireless communication device to communicate via a network connected to the image forming apparatus, and a control device. The control device includes an authentication unit that determines whether o a device within short-range wireless communication range has been authenticated. The control device sets up a connection for data communication via the network when the portable terminal has been authenticated and set up the direct wireless connection for data communication when the portable terminal has not been authenticated.

Image forming apparatus and data communication method of image forming apparatus

A vessel propulsion device transmits a drive force of an engine to a propulsive force generator. The vessel propulsion device includes a generator that is driven by the engine, a power shutoff detector that detects a power shutoff state in which the drive force of the engine is not transmitted to the propulsive force generator, and a controller configured or programmed to, when the power shutoff detector detects the power shutoff state, select one of a plurality of charging modes to charge a battery connected to the generator and control a target speed of the engine based on a selected one of the charging modes.

Vessel propulsion device

A communication apparatus for an information processing apparatus includes: a data acquiring unit which acquires data; a determination unit which determines whether a volume of the data is greater than a reference value or not; a wireless communication method deciding unit which decides a wireless communication method, and which decides a wireless communication method to be used for data transmission, based on a communication speed of each method if the determination unit determines that the volume of the data is greater than the reference value, and decides a wireless communication method, based on power consumption if the volume of the data is determined as equal to or smaller than the reference value; and a wireless communication processing control unit which controls processing to transmit the data.
