Abstract: An input interface receives a trigger signal. A processor displays a first screen or a second screen on a display device based on the trigger signal. The first screen provides first medical information for each of a plurality of subjects. The second screen provides, for at least one of the plurality of subjects, second medical information that is not included in the first medical information.

Abstract: The biological signal averaging processing device includes a waveform input unit for continuously obtaining a biological signal in which analogous waves appear repeatedly, a summing-averaging processing unit which sums the biological signal obtained from the waveform input unit each time a predetermined time period lapses after a desired start time point to obtain an average wave, a noise level detection part which detects a noise level of random noise contained in the biological signal obtained from the waveform input unit each time the predetermined time period lapses after the desired start time point, a display part for displaying information, and a display control part for displaying the information on the screen of the display part. The display control part displays the noise levels detected by the noise level detection part on the screen of the display part in a chronological manner in association with the respective predetermined time periods.

Abstract: A life preserver used in pairs characterized by an inflatable air bag with an opening through the center for an arm to slip through. An arc-shaped inflator is attached to the top of the air bag. This also serves as a pull catch for extracting the folded pair of life preservers from pockets where they are stored. The air bag is preferably made from a strong, thin, airtight material. A belt, one end of which attaches inside the pocket where the folded air bag is stored, is attached to the bottom of the air bag, and remains attached after the air bag is extracted, inflated and put to use.
