Publication number: 20190059790Abstract: A blink detection apparatus includes an eyelid state index value measurement unit configured to chronologically measure an eyelid state index value, and a signal processing device. The signal processing device is configured to determine that a blink, occurs when a change width of the measured eyelid state index value from a baseline that is a reference value of the eyelid state index value in a case where eyelids are in an opened state exceeds a magnitude of a threshold from the baseline, to count the number of times when the change width of the measured eyelid state index value from the baseline exceeds the magnitude of a tentative threshold from the baseline, and to set the threshold to a tentative threshold at which change in the number of times with respect to the tentative threshold is minimal.Type: ApplicationFiled: July 30, 2018Publication date: February 28, 2019Applicant: Toyota Jidosha Kabushiki KaishaInventor: Masahiko Yoshii

Publication number: 20190059793Abstract: A diagnostic Electrochemical Impedance Spectroscopy (EIS) procedure is applied to measure values of impedance-related parameters for one or more sensing electrodes. The parameters may include real impedance, imaginary impedance, impedance magnitude, and/or phase angle. The measured values of the impedance-related parameters are then used in performing sensor diagnostics, calculating a highly-reliable fused sensor glucose value based on signals from a plurality of redundant sensing electrodes, calibrating sensors, detecting interferents within close proximity of one or more sensing electrodes, and testing surface area characteristics of electroplated electrodes. Advantageously, impedance-related parameters can be defined that are substantially glucose-independent over specific ranges of frequencies. An Application Specific Integrated Circuit (ASIC) enables implementation of the EIS-based diagnostics, fusion algorithms, and other processes based on measurement of EIS-based parameters.Type: ApplicationFiled: October 25, 2018Publication date: February 28, 2019Inventors: Ning Yang, Raghavendhar Gautham, Rajiv Shah
