  • Patent number: 8036206
    Abstract: In a commutation system, a data packet is transmitted and received by radio among radio communication apparatuses. In the communication system, the data packet is started to be transmitted on a transmission right acquired on contention type access control in response to a transmission request for the data packet. It is detected that there is a predetermined state in which the transmission request is generated during or after reception of a long packet which is over a given packet length. When the predetermined state is detected, a start timing of the access control is shifted to a timing at which a desired delay time passes after completing reception of the long packet. One example is that an elapse time from a start of reception of the long packet to generation of the transmission request is measured and, as the desired delay time, a period of time calculated by multiplying the measured elapse time by a specified coefficient is set.

  • Publication number: 20100198459
    Abstract: Application data generated by an ECU is wireless transmitted by a transmission device in a subject vehicle so as to periodically change a communications distance by changing, every transmission timing, at least one of (i) a transmission rate, which is used in transforming a transmission packet into a transmission signal in a modulation section, and (ii) a transmission power, which is configured by an amplification section to amplify the transmission signal. As a result, the data transmission from the subject vehicle can be made (i) in high repetition times with respect to a nearby vehicle having a greater risk of collision (i.e., time to collision being shorter), and (ii) in low repetition times with respect to a distant vehicle having a less risk of collision (i.e., time to collision being longer).

  • Patent number: 7382737
    Abstract: Fragment data is generated with respect to a certain data aggregate that is one of a plurality of data aggregates using a coded matrix. The fragment data is capable of restoring the certain data aggregate based on the coded matrix when the fragment data is collected to a required count. The generated fragment data is provided with an identification code associated with the certain data aggregate restored by the fragment data. The fragment data having the identification code is transmitted to a transmission channel. Further, the same transmission channel can be used to transmit the multiple pieces of the fragment data corresponding to the multiple data aggregates. When a receiving party is previously notified of the identification code, it can receive the fragment data by distinguishing which fragment data should restore which data aggregate.

  • Patent number: 7145518
    Abstract: A multiple-frequency common antenna has a first substrate sheet and a second substrate sheet respectively structured by an HIP consisting of a metal plate, small metal plates disposed in two dimensions and linear metal bars connecting these elements. The antenna restricts propagation of surface currents of the first and second frequency bands which are not overlapping with each other. An inverse L-shape antenna and a monopole antenna which are fed with a center conductor and an external conductor of the coaxial line respectively operate as the antenna on the first substrate sheet in the first frequency band and second frequency band. The second substrate sheet does not propagate the radiated wave of the monopole antenna, thereby avoiding unwanted re-radiation.
