Abstract: A data processing section selects either base station mode or terminal mode and executes communication. A control section controls operations relating to the base station mode and the terminal mode. A receiving section receives an instruction to switch to the base station mode from other wireless device set in the base station mode, in the case where communication is set in the terminal mode. An AP switching section switches to the base station mode in accordance with the instruction. An instructing section instructs other wireless devices set in the terminal mode to switch to the base station mode, after a predetermined period is passed from the time when the mode is switched to the base station mode. An STA switching section switches to the terminal mode after giving the instruction.

Abstract: A processing unit sets the time interval before packet signals are broadcast, using a carrier sense multiple access (CSMA) scheme. A modem unit and an RF unit broadcasts the packet signals at the time intervals set by the processing unit. The RF unit and the modem unit receive a control signal broadcast from an access control apparatus at a predetermined frequency. The processing unit sets the time interval, during which the control signal is receivable, to a time length shorter than the time interval for the remaining cases.

Abstract: A data processing unit selects either one of a base station mode and a terminal mode so as to perform communications using packet signals. The base station mode is a mode in which a packet signal, containing data indicating that an initial source and a final destination are not its own radio apparatus, is to be communicated; the terminal mode is a mode in which a packet signal, containing data indicating that the initial source or the final destination is its own radio apparatus, is to be communicated. A control unit starts the radio apparatus by setting the data processing unit in the terminal mode. When a packet signal, which has been transmitted from another radio apparatus and which contains broadcast information, has not been received before a certain period of time elapses after the start, the control unit switches the mode of the data processing unit to the base station mode.

Abstract: An RF unit and a modem unit receive a packet signal, containing information regarding a frame construction, which is transmitted from a base station apparatus in a first period of a frame at least including first periods and second periods. An extraction unit identifies the second period in the frame, based on the received packet signal. A setting unit sets a waiting time period in the identified second period. A carrier sensing unit carries out carrier sensing over the waiting time period set by the setting unit. The modem unit and the RF unit broadcast the packet signal based on a result of the carrier sensing.

Abstract: An airbag device is provided in which since part of a base fabric of the airbag (16) excluding an occupant restraining face (16d) is joined by stitchings (S1 to S3) having breaking strengths that increase in going from an already deployed portion toward a not yet deployed portion, during the process of deploying the airbag by gas generated by an inflator, the stitchings (S1 to S3) of the airbag (16) break from the already deployed portion toward the not yet deployed portion, and the airbag (16) is continuously inflated from the occupant restraining face (16d) side toward the inflator side. As a result, it is possible to stabilize the shape of the airbag (16) during the process of deployment and to inflate the occupant restraining face (16d) of the airbag (16) at an early stage, thus ensuring occupant restraining performance.

Abstract: A map data storage unit holds map data in which a road ID is allocated, as identification information, to every preset section of at least part of roads. A traffic jam determination unit determines whether the section corresponding to every road ID is congested. A transmission unit performs broadcast transmission of vehicle data including a road ID and the traveling speed of a vehicle from the vehicle traveling in each section of a road. At the time, the transmission unit forms a frame in which the received vehicle data of other vehicle and the vehicle data of a driver's vehicle are combined. An information compressing unit compresses an amount of data by deleting the traveling speed from the frame with respect to a section that has been determined not to be congested by the traffic jam determination unit.

Abstract: A setting unit defines the first frame and the second frame and selects use of the first frame or the second frame. A generation unit generates control information which is defined by the same format regardless of the selection by the setting unit and which includes at least information related to the base station broadcast period. The generation unit puts information related to the ratio between the priority period and the general period into the control information and reflects the selection by the setting unit to the ratio. The modem unit and the RF unit broadcast a packet signal including the control information in the base station broadcast period.

Abstract: An acquiring unit receives a packet signal of a first type from the other base station apparatus. A measuring unit measures a receipt frequency of the packet signal of the first type which is received. A determining unit determines a timing for broadcasting a packet signal of a second type to inform a terminal apparatus of a presence based on the receipt frequency which is measured and a receipt timing of the packet signal of the first type which is received. A broadcasting unit broadcasts the packet signal of the second type in the determined timing. A communicating unit executes a communication with the terminal apparatus receiving the packet signal of the second type.

Abstract: A measuring unit measures a quality of a received packet signal. An estimating unit estimates entry from a second area to a first area when the measured quality is improved so as to satisfy a first condition and estimates the entry from the first area to the second area when the quality measured by the measuring unit is deteriorated so as to satisfy a second condition. The estimating unit sets different values for a parameter included in the first condition and the parameter included in the second condition. The determining unit determines a first period or a second period as transmission timing based on an estimated result.

Abstract: A base station apparatus controls inter-terminal communication. Basic information containing information about a first period and extended information containing the information about a second period and a third period are defined and a generation unit generates a packet signal containing an identifier to identify whether the basic information of the basic information and the extended information is contained in the packet signal or the basic information and the extended information are contained in the packet signal. A modem unit and an RF unit broadcast the packet signal containing the identifier generated by the generation unit.

Abstract: A radio unit transmits a packet signal. An acquiring unit acquires information about a traveling status of a vehicle. When the acquired information indicates a stop of the vehicle, an instructing unit allows the radio unit to stop transmitting the packet signal. A position detecting unit detects, based on positional information of the vehicle, whether the vehicle is present in a predetermined area. If the position detecting unit detects presence, the instructing unit allows the radio unit to continue transmitting the packet signal even when the information acquired by the acquiring unit indicates the stop of the vehicle.
