Abstract: A terminal device has: a sensor unit which perform a measurement; a position detection unit which acquires information for specifying a position; a timing unit which acquires time information; a communication unit which communicates via a communication network; and a control unit. The control unit generates position information for indicating a position of the terminal device by the position detection unit. Besides, the control unit changes accuracy of the position information within a predetermined range, and generates information for transmission related with the changed position information, the time information gotten by the timing unit, and measurement information indicating a measurement result of the sensor unit. In addition, the control unit controls the communication unit so as to transmit the information for the transmission to an information processing device via a communication network.

Abstract: An information communication terminal performs communications with another information communication terminal over a radio communication network system. In the information communication terminal, a receiving unit receives an externally transmitted frame. In a state where error correction is to be performed, a correction processing unit outputs data after performing error correction according to correction information in the frame on data in the frame received by the receiving unit. In a state where the error correction is not to be performed, the correction processing unit outputs the data without performing the error correction on the data in the frame received by the receiving unit. A determining unit determines whether the error correction is to be performed by the correction processing unit or not.

Abstract: A terminal connected to a wireless communication network includes a BU processor used in wireless communication. An operation mode of the BU processor is switched to one of a sleep mode, a standby mode, and an active mode in a state in which an electric power is supplied to the BU processor. In the sleep mode, a PLL circuit stops a clock supplied to each circuit in the BU processor. In the standby mode, an operating frequency is set at a predetermined first frequency. In the active mode, the operating frequency is set at a second frequency higher than the first frequency. Accordingly, in the state in which the electric power is supplied, the operating frequency is switched and the number of operating circuits is switched, thereby reducing electric power consumption in the terminal.

Abstract: At a client, when first time data received from a server prior to continuous transmission of audio data of the server is set at a second timer, the second timer initiates time-counting from the set first time data. Accordingly, during the subsequent continuous transfer period of audio data, the timers of the server and client are adjusted to output the same time data in synchronization with each other. During the continuous transfer period, the client stores in a memory audio data that has been continuously transmitted according to the sequence to be output via a speaker from the server. The audio data is stored in the received sequence. Unit of audio data whose assigned first time data matches the second time data output from the second timer is searched for among the audio data in the memory to be output via the speaker.

Abstract: A terminal includes a communication unit. The communication unit determines which one of an AP mode and an ST mode is set as an operating mode of the terminal. In the ST mode, the communication unit accepts a received frame, and then outputs the accepted frame to a host system. In the AP mode, the communication unit transmits the received frame as it is to a wireless network, that is, relays the frame.
