  • Patent number: 9622154
    Abstract: A mobile ad hoc network including the communication terminals for cognitive radio communication may have a problem that it takes time for the terminal to newly participate in the network. A radio communication terminal already participating in a mobile ad hoc network includes a pulse pilot generating unit which converts a pulse signal having a predetermined pattern into a radio signal and outputs the obtained radio signal at an unused frequency, after participating in the mobile ad hoc network. A radio communication terminal to participate in a mobile ad hoc network includes a pulse pilot checking unit which checks whether any pulse signal having a predetermined pattern exists in a radio signal for each predetermined frequency and performs a participation process for the frequency of each radio signal including the pulse signal, the participation process including inquiring whether the radio communication terminal can participate in the mobile ad hoc network.

  • Patent number: 8368506
    Abstract: A sensing device includes a situation acquisition unit acquiring information on situation of a site of interest sensed; a sensing range change unit changing sensing range of the situation acquisition unit; a position identification unit identifying position of the situation acquisition unit; and a sensing operation controlling unit which detects inhibited content, a subject of inhibition of transmission, from the information on the situation of the site of interest. If the inhibited content has been detected, the sensing operation controlling unit calculates position of the inhibited content based on the position identification information from the position identification unit. The sensing operation controlling unit controls the sensing range change unit, based on the position identification information including the position of inhibited content calculated, so that the position of inhibited content is not contained in the sensing range.

  • Publication number: 20110199491
    Abstract: Disclosed is a system to determine whether calibration indices are appropriate for each camera when calibrating large quantities of cameras, in which there is great variation in individual differences in image blurring characteristics. The present invention takes an image of a calibration index and calculates the calibration precision that can be expected in calibration from the calibration index image that has been taken. If the calibration precision that can be expected is not optimal for each camera, the density of lines or shapes that constitute the calibration index is changed until the optimum calibration index for each camera is found.
