Abstract: In an MRI apparatus, an imaging that produces almost no sound is implemented without extending an imaging time, not only for three-dimensional imaging, but also for two-dimensional imaging. A gradient pulse in a pulse sequence provided in the MRI apparatus is adjusted by using a basic waveform having a distribution of frequencies where strength dwindles substantially as the frequency increases from zero, and the waveform is convex upward or downward varying smoothly. An application time and strength are adjusted so that almost no sound is produced. Any imaging executable by a conventional pulse sequence can be implemented without producing almost any sound, using the conventional pulse sequence with little change.

Before data communication is performed with an information processing apparatus via an antenna of the communication terminal apparatus, the antenna controller changes at least one of a resistive component of the antenna, voltage to be applied to the antenna, and current to be applied to the antenna, thereby changing a state of the antenna to cause a change in a magnetic field that results from the change in the state of the antenna and can be sensed by the information processing apparatus. After the antenna controller has changed the state of the antenna, the target-side data transceiver performs the data communication with the information processing apparatus.

The mobile terminal and the BLE terminal establish a connection therebetween and perform communication with each other at a predetermined time interval. The mobile terminal transmits representation data to the BLE terminal, and the BLE terminal performs a first representation on the basis of the representation data. After the first representation ends, when a button operation is performed in the BLE terminal, operation result information indicating the button operation is accumulated in the BLE terminal. The accumulated operation result information is transmitted from the BLE terminal to the mobile terminal at a timing at which communication between the mobile terminal and the BLE terminal is performed next. The mobile terminal performs, for example, a game process on the basis of the operation result information from the BLE terminal.
