  • Wireless detonator, wireless detonation system, and wireless detonation method
    Patent number: 10584949
    Abstract: A wireless detonator (10) includes a detonation side receiving antenna (11), a detonation side transmitting antenna (18), an initiator (14) and a detonation side electronic circuit. The detonation side receiving antenna (11) receives energy for driving the detonation side electronic circuit, a control signal and an initiation signal. The detonation side electronic circuit receives the energy, the control signal and the initiation signal via the detonation side receiving antenna (11), transmits a response signal via the detonation side transmitting antenna (18) and ignites the initiator (14) in accordance with the initiation signal. A response frequency of the response signal is set to be greater than or equal to 100 MHz and less than or equal to 1 GHz.

  • Radio control transmitter
    Patent number: 9836954
    Abstract: A trigger includes a segment for exercising throttle control and a segment for exercising brake control. A switch is provided in a radio control transmitter. The switch can be depressed by pulling the trigger in a direction of an arrow A. Setting of full throttle can be assigned to the switch. Full throttle can be turned on only when the switch is depressed by the trigger. It is possible to control on/off of the full throttle easily.
