Abstract: An object is to provide programs for reliable predictions of the day of ovulation. A process is executed in a program for predicting a day of ovulation on a computer, the process including calculating a predicted ovulation day data corresponding to a particular menstrual cycle by applying the particular menstrual cycle to a relationship between a period between a menstrual day and a day of ovulation and an average length of a menstrual cycle, the relationship being estimated based on data of a plurality of persons which have been previously obtained.

Abstract: The purpose of the present invention is to reduce the introduction cost of an indoor positioning system using inaudible sound. A positioning system according to one embodiment includes a first acquisition unit, a second acquisition unit, and a positioning unit. The first acquisition unit acquires a reception log indicating that a fixed receiver receives signal source-specific inaudible sounds from multiple signal sources. The second acquisition unit acquires, from a storage unit, signal source information on multiple signal sources corresponding to a fixed receiver installed near a mobile terminal. Here, the signal source information contains information for identifying a signal source from inaudible sound, the transmission timing of inaudible sound at the signal source, and the location of the signal source.

Abstract: An oscillometric method for determining hemodynamic parameters of the arterial portion of patient's circulatory system, consisting in recording the pulse pressure waves in the major arterial vessel under examination, under the effect of a linearly varying pressure in a pneumatic vessel-constricting pressure cuff, with the result that a closed contour is formed within a single measuring cycle, which is established by straight lines the points of intersection of which are the signs of arterial pressure, while the amplitude values of the pulse waves in the contour determine the geometric parameters of the major arterial vessel under examination. A measuring system for carrying the method into effect features a linear characteristic of conversion and a straight horizontal amplitude-frequency characteristic in a frequency range of approximately from 0 to 50 Hz along a through path of conversion, amplification, and recording.
