摘要： Each wireless communication apparatus forming a wireless network has an operation mode in which a wireless communication apparatus becomes a control station with priority, an operation mode in which a wireless communication apparatus may operate as a control station, and an operation mode in which a wireless communication apparatus does not become a control station. By providing a function in which a user selects and sets one of these three operation modes, the wireless network can be constructed as desired by the user. As a result of providing the mode in which the wireless communication apparatus does not become a control station, a wireless communication apparatus that is connected to a device but that cannot operate as a control station is not specified as a control station. Therefore, by allowing a specific apparatus in the wireless network to function as a control station, the wireless network can be constructed.

摘要： A communications system sets a network frame period that can be repeatedly used by a plurality of wireless networks in a predetermined time period. A plurality of channel slots for use by each of the wireless networks is prepared in advance in the network frame. A coordinator operating a PAN activates its PAN in an area of a channel slot that is not used by the other coordinator(s). Since each of the wireless networks detects an unused channel slot in the network frame and uses the unused channel slot, the association process is greatly simplified.

摘要： A system and method for performing ranging and positioning as follows by using the procedure for packet transmission and reception between a sender and a recipient. A first radio set transmits packets to a second radio set as a recipient. The second radio set returns the packets without fail after the lapse of time (from the detection of packets) which corresponds to an integral multiple of a prescribed unit time. The first radio set counts, by using its counter, the time which has elapsed from its transmission of packets to its detection of packets from the second radio set. The remainder of the thus counted time after subtraction of the time taken by the second radio set from packet detection to packet return and the processing time of the first radio set itself is converted into the distance of propagation between the first radio set and the second radio set as a recipient.

摘要： An inner-space-sectioned tube wherein, in manufacturing the tube having four or more independent fluid channels formed inside thereof, while at least two lengths of inner tubes are set to inscribe an outer tube, cold working is applied, which is a simple manufacturing process, thereby enabling to reduce the number of cold drawing passes and allowing the inner space of the tube, even if the outer tube is small in size, to effectively be allocated for four independent fluid channels. Further, this inner-space-sectioned tube adopts a simple tube structure wherein the number of constituting members is reduced, thereby enabling to reduce weight while ensuring tube strength and to achieve further reduction of manufacturing costs.

摘要： A spread code sequence generator generates a spread code sequence with the frequency of a synthesizer, and then outputs the spread code sequence to a multiplier. The multiplier outputs a spread signal obtained by multiplying a data sequence by the spread code sequence to an impulse generator. The impulse generator generates an impulse signal of very fine impulses that corresponds to 0s/1s of the spread signal. The impulse signal is outputted to a band pass filter, where a predetermined range of the impulse signal is extracted. The output of the band pass filter is fed to a subtracter and a delay circuit. The delay circuit delays the delayed signal by a predetermined period. The delayed signal is outputted to the subtracter. The subtracter subtracts the delayed signal from the output of the band pass filter. A signal obtained by such subtraction processing is transmitted as a transmission signal via an antenna.

摘要： For the purpose of efficient transmission based on the UWB system, first and second baseband waveforms are generated at a cycle equivalent to an integral multiple of a carrier to have a specified phase difference from each other. The first baseband waveform is multiplied by the carrier and a first transmission data sequence to acquire a first transmission waveform. The second baseband waveform is multiplied by a phase shifted carrier and a second transmission data sequence to acquire a second transmission waveform. The first transmission waveform is mixed with the second transmission waveform to acquire a transmission signal. The transmission signal is transmitted as a π/2 shift BPSK signal to transmit a UWB signal. Selecting the baseband waveforms and the carrier makes it possible to configure the transmission band and easily provide division multiplexing transmission.

摘要： A receiver for generating a transmission symbol stream by applying predetermined modulation processing to an encoded bit series obtained by encoding an information bit series having a predetermined transmission rate. The receiver generates a transmission-information bit series having a transmission rate lower than a predetermined transmission rate in accordance with an information bit series and receives a transmission signal generated in accordance with the transmission-information bit series through a communication channel. The receiver stepwise increases the low transmission rate of the transmission-information bit series to reach a predetermined transmission rate by stepwise increasing the low transmission rate, while stepwise increasing the number of communication channels to be used in accordance with the stepwise increase of the low transmission rate.
