Abstract: The reliability of calculated bio-information of a subject is determined. When the reliability of the bio-information is determined to be high, the bio-information is output, whereas when the reliability of the bio-information is determined to be low, the bio-information is not output. Thus, among the calculated bio-information, only the bio-information of high reliability may be output, or distinctive display may be performed depending on the reliability, whereby it is possible to provide a bio-information output device and the like capable of easily determining bio-information of high reliability.

Abstract: A scratching detection system includes a sensor and processor. The sensor is configured to detect acceleration corresponding to movement of a person's hand and is configured to output a first signal including a detected value corresponding to the acceleration in a first cycle. The processor is configured to acquire the first signal and to detect a scratching behavior of the person in a second cycle based on a plurality of parameters. The second cycle includes a plurality of the first cycles. The plurality of parameters includes a first occurrence count and a first consecutive count. The first occurrence count is a number of times an absolute value of the detected value exceeds a threshold value in the second cycle. The first consecutive count is a maximum value of a number of times that the absolute value of the detected value consecutively exceeds the threshold value in the second cycle.

Abstract: A biological signal of a subject is acquired so as to calculate biological information from the acquired biological signal. When the biological information has been determined to be anomaly, whether the biological information is one that was calculated under a high-accuracy condition is determined. When the biological information is determined to be one that was calculated under the high-accuracy condition, a notice is given based on a first criterion. In the other cases, a notice is given based on a second criterion. Thereby, it is possible to provide an abnormality notification system that can give a necessary notification appropriately while suppressing unnecessary notification, by changing the criteria for notification in accordance with the accuracy of the determined biological information when the biological information of the subject was determined to be anomaly.
