摘要： An electrogastrograph measures an electric signal derived from the stomach's action. The signal is decomposed into its frequency components by means of a plurality of band pass filters, and stored in a storage medium. A method for analyzing data obtained by the electrogastrograph comprises the steps of: decomposing the signal into its frequency components by means of the band pass filters; and, evaluating the stomach in its action on the basis of variations in amplitude of said frequency components.

摘要： In a method for weighing a patient lying on a bed, an air mattress is put beneath the patient. Then, a flowing air is supplied to or discharged from the air mattress so as to balance the weight of the patient with a pressure of a body of air contained within the air mattress. At this time, the amount of the flowing air is measured together with variation of the pressure of the body of air contained within the air mattress, so that a relationship between the amount of the flowing air and the variation of the pressure of the body of air contained within the air mattress is established. Consequently, the weight of the patient may be calculated on the basis of the relationship between the amount of the flowing air and the variation of the pressure of the body of air contained within the air mattress.

摘要： Even when a time series data varies in a relatively short period of time as is in a series of signals issued from a living organism, it is possible for the present invention to have a doctor precisely grasp variations in amplitude of even a weak one of frequency components of the time series data. In order to decompose the time series data into a plurality of the frequency components according to the present invention, a set of band pass filters are prepared. The band pass filters have their cut-off frequencies shifted or offset from each other by their passing band widths, respectively. The individual band pass filters process the time series data to produce such frequency components. These frequency components are then sampled in amplitude at predetermined time intervals. The thus sampled amplitudes of the frequency components are transformed into corresponding densities of a predetermined color including a gray color according to a predetermined color scale or a predetermined gray scale, and then displayed on a display screen on the basis of a time base of the display screen.
