  • Publication number: 20110319040
    Abstract: It is become accumulation independently with physical layer circuit and the MAC circuit, and an RF integrated circuit for development for the radio transmission and reception that the interface frequency with the physical layer circuit has width of at least around 10 MHz toward is related to. It is RF integrated circuit 1 for the development that the switching circuit which changes a demodulation circuit and a modulation circuit and an antenna to either of demodulation circuit 11 and modulation circuit 12 was built in, and RF integrated circuit 1 is made accumulation independently with physical layer circuit 21 and MAC circuit 22 and demodulation circuit 11 converts a received radio frequency signal into a frequency signal of frequency 5-20 MHz, and modulation circuit 12 converts a frequency signal of frequency 5-20 MHz into a radio frequency signal.

  • Publication number: 20110316719
    Abstract: A vehicle sensor and a human sensor are comprised to a traffic sign and the road surface indicator, and warning is displayed in mark, indicate lamp where a driver is easy to make viewing. With intersection safety driving system 100, the control unit can detect vehicle V1, V2 which are going to come in the intersection by vehicle sensor 112 comprised on the traffic sign which there is. When vehicle sensor 112 did vehicle V1, V2, indication to rouse (in indicating lamp 1A, 1B, 1C, 1D), the attention to the vehicle in traffic sign 8A, 8B, 8C, 8D installed in the road which the vehicle drives and the intersecting road is performed.

  • Publication number: 20110319039
    Abstract: Demodulation/modulation circuit provides the RF circuit which had demodulation/modulation circuit working by a common component built-in at both the recovery and the modulation substantially. Demodulation/modulation circuit 15 includes at least low noise amplifier A1 and the image rejection mixer IRM and power amplifier A2 as a common component. Also, switching circuit 131,132,133,134 changing the signal paths that send out the signal paths that send out a signal from radio antenna ANT to a the physical layer circuit through demodulation/modulation circuit 15 and the signal from a the physical layer circuit to radio antenna AT through demodulation/modulation circuit 15 is comprised.
