  • Patent number: 11948673
    Abstract: A blood purification system is provided that is capable of effectively utilizing accumulated histories stored during blood purification treatment and that helps take a quick and appropriate action in response to any event that occurs unsteadily or any transition of a parameter. The blood purification system includes an extracting unit that searches histories accumulated in a storage unit and extracts, as reference histories, a plurality of histories each including any of events having occurred during the current session of blood purification treatment or a plurality of histories each including a parameter approximate to that observed during the current session of blood purification treatment; a list-creating unit that creates a list of the plurality of reference histories extracted by the extracting unit; and a display control unit that controls the list created by the list-creating unit to be displayed on a display unit.

  • Patent number: 6643527
    Abstract: A power switching unit of a portable telephone which has a function of storing data such as telephone numbers and operates with a battery. The unit comprises a battery for supplying power to a radio unit and a control unit which contains a data storage function and controls operation of the radio unit, first voltage monitor means for monitoring a supply voltage of the battery to output a first voltage drop signal when the supply voltage falls below a first predetermined value, and communication disconnection means for stopping power supply to the radio unit upon reception of the first voltage drop signal. The power switching unit of the portable telephone further includes voltage adjustment means for adjusting voltage suppled to the control unit from the battery to a predetermined operating voltage of the control unit for supplying it to the control unit.

  • Patent number: 6058164
    Abstract: The present invention relates to a mode-switchable telephone and mode setting and switching methods for the telephone. The mode-switchable telephone has a comparing unit which compares a value of a ringer adjusting volume with a volume value for setting a second mode, and a control unit which switches a first mode to the second mode when it is determined based on the result of the comparison by the comparing unit that the value of the ringer adjusting volume is set to be equal to or less than the volume value for setting the second mode. This structure facilitates the operation of the telephone having an automatic answering/recording function and a simple pager function.

  • Patent number: 5371800
    Abstract: A speech detection circuit includes an amplifier for amplifying an input audio signal and having a variable gain, a rectifying circuit for rectifying an output signal of the amplifier, a comparator for comparing an output signal level of the rectifying circuit with a reference level, and a control circuit for outputting a control signal based on an output signal of the comparator. The control circuit outputs a control signal which indicates a power save mode after a predetermined time elapses from a time when the output signal level of the rectifying circuit becomes less than or equal to the reference level, and outputs a control signal which indicates a normal mode immediately when the output signal level of the rectifying circuit becomes greater than the reference level. The amplifier receives the control signal output from the control circuit and reduces its gain when the control signal indicates the power save mode.
