  • Patent number: 8265578
    Abstract: In a radio receiving apparatus, an analog received signal is converted into a digital received signal. An unwanted wave in an adjacent channel band is rejected, that is adjacent to a passband for the digital received signal. The digital received signal with no unwanted wave is converted into a first demodulated signal. The first demodulated signal is converted into a second demodulated signal in analog form. A noise component is extracted from the first demodulated signal. The second demodulated signal is suppressed under squelch control when a squelch voltage that is a voltage of the noise component after rectification and smoothing becomes equal to or higher than a predetermined threshold level.

  • Patent number: 8216149
    Abstract: An ultrasound diagnostic apparatus including an ultrasonic probe transmitting and receiving ultrasound toward and from a subject, a puncture adaptor configured to be fixed to the ultrasonic probe and to hold a puncture needle, wherein the puncture adaptor has moving part movable in relation to the ultrasonic probe with the puncture needle, and a sensor provided at the ultrasonic probe, and configured to detect the position of the moving part. As the puncture needle is moved relative to the probe, the movable part is correspondingly moved relative to the probe, and movement of the movable part, and therefore also of the puncture needle, is detected by the sensor.
