  • Patent number: 9018973
    Abstract: A device, comprising an output terminal; an output circuit coupled to the output terminal and having an adjustable impedance; and an impedance adjustment circuit adjusting stepwise the adjustable impedance so as to head toward a first reference impedance. The impedance adjustment circuit changes the adjustable impedance by a first amount when the adjustable impedance is within a first range, and changes the adjustable impedance by a second amount when the adjustable impedance is out of the first range. The first amount is smaller than the second amount.

  • Publication number: 20150038122
    Abstract: Disclosed is a wireless communication system capable of easily reconnecting a mobile information terminal and a base unit when a user returns home and letting the user know missed incoming call information or the like. To this end, when being unable to receive a signal from the base unit, the mobile information terminal enters into a sleep state, and when a predetermined operation is performed, the mobile information terminal searches for the base unit, and when reconnecting to the base unit, the terminal displays information on an item transmitted from the base unit on an operation display section. Thus, even when the user returns home but forgets switching an operation mode, the mobile information terminal searches for the base unit as soon as the predetermined operation is performed, and can obtain necessary information from the base unit at home by a simple operation when the user desires the information.

  • Publication number: 20140276229
    Abstract: An information analyzing apparatus (100) of the present invention includes a waveform feature determining unit (30) and a sound-type determining unit (40). The waveform feature determining unit (30) applies waveform feature determination criteria used for classifying features of sound waveforms to a sound waveform included in body sound information collected by a stethoscope so as to specify a feature of the sound waveform. The sound-type determining unit (40) determines a sound type to which the body sound information belongs, on the basis of the feature of the sound waveform specified by the waveform feature determining unit (30). With this configuration, it is possible to analyze body sound information objectively and highly precisely and to present analysis results so that a user can efficiently utilize them.

  • Publication number: 20140171041
    Abstract: An operation for reconnecting a mobile information terminal and a base unit, which is performed when a user returns home, is made easier, and a matter that has occurred in the base unit during his absence is displayed on the mobile information terminal. The mobile information terminal enters a sleep state when receiving no signal from the base unit. When the user performs a predetermined operation, the mobile information terminal returns from the sleep state, then searches for the base unit, and displays, on a display section, information relating to the matter that has occurred during his absence, the information being transmitted from the base unit when the terminal is reconnected to the base unit. Accordingly, the user can know, through a simple operation, the record of an incoming call received through a wired network, or an answering machine message that has occurred during his absence from the base unit.

  • Publication number: 20120226174
    Abstract: In a pulse wave velocity measurement device (10), reference times (T1, T2) for an ejection wave component (S1) and a reflected component (S2) of a pulse wave S are detected by a reference time detection unit (2), and amplitudes (W1, W2) of the pulse wave (S) that correspond to the reference times (T1, T2) for the ejection wave component (S1) and the reflected wave component (S2) are detected by a pulse wave amplitude detection unit (3). A pulse wave velocity detection unit (5) finds a velocity (PWV1) of the pulse wave (S) on basis of the reference times (T1, T2) for the ejection wave component (S1) and the reflected wave component (S2) and the amplitudes (W1, W2) of the pulse wave (S) that correspond to the reference times (T1, T2) for the ejection wave component (S1) and the reflected wave component (S2).
