    Abstract: The object is to provide a radio wave control system that is capable of suppressing radio wave interference. A radio wave control system according to the present disclosure includes a reflective plate (10) configured to reflect an undesired radio wave that causes interference for a communication apparatus, a control unit (21) that causes a reflected wave of the undesired radio wave to be transmitted in a direction in which the communication apparatus is present, and a communication unit (22) that receives interference information indicating an interference state in the communication apparatus, and the control unit (21) determines a phase of the reflected wave reaching the communication apparatus by using the interference information.

    Abstract: An object of the invention is to provide a new defect detection technique using an autonomously movable apparatus. In order to accomplish the object, the invention provides a detection system (10) including a drive control unit (15) that controls a driving unit (12) causing a base unit (11) to travel in a case where a predetermined detection target is detected on the basis of information collected by a sensor unit (13) installed in the base unit (11), and a second detection unit (16) that detects a predetermined defect on the basis of the information collected by the sensor unit (13).

    Abstract: [Problem] A mobile ad hoc network (referred to as a “network” below) including the communication terminals (referred to as a “terminal” below) for cognitive radio communication in Patent Literature 1 has a problem that it takes time for the terminal to newly participate in the network.[Solution] 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.
