Abstract: A first period when detection of a detection target body in contact with or proximity to a sensor is performed and a second period when detection of asperities on a surface of the detection target body is performed are set. First regions are set in a detection region of the sensor as input keys for a password. In the first period, one of segmented regions obtained by dividing a second region the center of which corresponds to coordinates of a touch detection position when the touch detection position for inputting of the password is detected in one of the first regions. In the second period, based on priorities set in advance according to the number of feature points of the detection target body, a segmented image detected in the segmented region for the inputting is output, and a certain number of segmented images are synthesized to generate a fingerprint image.

Abstract: According to an aspect, a sensor system includes: a first device including a first controller and a first communicator; and a plurality of second devices each including an altitude sensor, a blood oxygen saturation level sensor, a second controller, and a second communicator. The second controller of the second device is configured to transmit altitude information measured by the altitude sensor and biometric information measured by the blood oxygen saturation level sensor to the first device through the second communicator. The first device has determination information comprising determination thresholds for a blood oxygen saturation level corresponding to different altitudes. The first controller is configured to warn that the blood oxygen saturation level is lower than the determination threshold corresponding to the altitude information based on the altitude information and the biometric information received from each of the second devices through the first communicator and the determination information.

Abstract: A personal authentication system includes: a detection device having a first period in which detection of a detection target body is performed and a second period in which detection of asperities on a surface of the detection target body is performed; and a control device. The detection device has, as input keys for a password, first regions in a detection region. The detection device is configured to allocate mutually different segmented regions in a second region having center coordinates at touch detection coordinates detected in the first region in the first period for each key inputting of the password, and output a segmented image acquired in the segmented region in the second period to the control device for each key inputting of the password. The control device is configured to generate a fingerprint image by synthesizing the segmented images acquired in the respective key inputtings of the password.
