Abstract: A distributed antenna includes a strip member extending in a strip-like shape including a dielectric body of a plate shape having a first surface that is one surface of the dielectric body and a second surface that is opposite to the first surface; a transmission line provided on the first surface, on the second surface, or between the first surface and the second surface; and a plurality of antenna elements electrically connected to the transmission line and disposed in a distributed manner on the first surface or on the second surface, or electrically connected to the transmission line and disposed in a distributed manner between the first surface and the second surface.

Abstract: A video reproducing apparatus which comprises a radio control signal receiving portion, a video sound data reproducing portion connected to the radio control signal receiving portion, a video projection portion connected to the radio control signal receiving portion and the video sound data reproducing portion, speakers connected to the video sound data reproducing portion, a housing for accommodating the video sound data reproducing portion, the video projection portion, and the speakers, and a housing drive portion for moving the housing, and which drives the housing according to a control signal of the housing drive portion which controls the housing drive portion and which is received by the radio control signal receiving portion, projects the video sound data onto the video projection portion according to a control signal of the video sound data reproducing portion at an arbitrary position, and reproduces the data through the speakers.

Abstract: Radio control over a distance beyond the arriving distance of the conventional radio control and transmission of the continuous instruction signal on the real time are possible. The system provides DTMF signal generation means for modulation of a control signal for controlling a controllable section into DTMF signal, VOIP transmission means for receiving DTMF signal to generate VOIP signal for transmission to VOIP line, VOIP line capable of transmitting VOIP signal, VOIP receiving means for receiving VOIP signal for conversion into DTMF code, DTMF demodulation and retransmission means for conversion of regenerated DTMF signal into a radio control transmission signal and a controllable section for receiving the radio control transmission signal and the signal generated by DTMF signal generation means is driven by DTMF demodulation and retransmission means through VOIP line in order to control the receiving means.
