A driver abnormality determination apparatus includes circuitry configured to detect a driver state of a driver of a vehicle, detect a driving operation of the driver, detect an exertion level of an involuntary function of the driver based on the driver state, detect an exertion level of a driving function of the driver based on the driving operation; and determine driver abnormality based on the execution level of the involuntary function and the execution level of the driving function. On condition that a function level of one of the execution level of the involuntary function and the execution level of the driving function is equal to or lower than a specified determination criterion, the circuitry is configured to relax a determination criterion for the other function level.

[Solution] A driver abnormality determination system includes circuitry configured to detect a driving operation of a driver, detect behavior of the driver's head and motion of eyeballs and/or movement of a sightline of the driver, recognize a driving scene in which the vehicle is driven; a memory that stores a sensor table of a relationship between the driving scene and detected values to be used to determine a driver abnormality; and determine the driver abnormality based on the sensor table, the driving scene, the driving operation and the behavior.

Driver abnormality determination system, method and computer program

A driver condition estimating device includes circuitry configured to measure movement of the head of a driver output from a driver camera that photographs the driver and detect a sign of abnormality of the driver from the movement of the head. The circuitry determines existence of the sign of abnormality of the driver by calculating a periodic feature amount from time series data showing movement of the head of the driver, calculating coherence between the movement of the head of the driver and lateral acceleration acting on the head of the driver, calculating time series variation patterns from the obtained periodic feature amount and the obtained coherence, and comparing the obtained time series variation patterns with a predetermined threshold.

Driver condition estimating device, driver condition estimating method and computer program therefor

A driver condition estimating device includes circuitry configured to measure movement of the head of a driver from output of a driver camera and detect a sign of abnormality of the driver from the movement of the head. On condition that lateral acceleration acting on the head of the driver is a predetermined value or less, the circuitry is configured to calculate a periodic feature amount from time series data showing the movement of the head of the driver, calculate a time series variation pattern from the obtained periodic feature amount, and compare of the obtained time series variation pattern with a predetermined threshold.

In a seat component received in a receiving region of a first body of a body, one surface of a contacting portion and one surface of an engaging portion are planar and are flush with each other, and the other surface of the contacting portion and the other surface of the engaging portion are planar and are flush with each other. The engaging portion engages two portions of the first body, which form one opening of the receiving region, in a state where a distal end of the seat component reaches another opening of the receiving region. Furthermore, in the state where the engaging portion engages the portions of the first body, a second body of the body covers the one opening and contacts the engaging portion. Thereby, the engaging portion engages the three portions of the body, so that movement of the seat component is effectively limited.

A reflection-type terahertz spectrometer includes an input optical path through which terahertz waves are propagated, an irradiating mechanism that irradiates a sample with terahertz waves propagated through the input optical path, an output optical path through which terahertz waves exiting from the irradiating mechanism are propagated, and a detector that receives and detects the terahertz waves propagated through the output optical path. The irradiating mechanism has at least one planar interface and a refractive index greater than that of a peripheral region contacting the planar interface and is disposed between the input optical path and the output optical path such that the terahertz waves propagated through the input optical path to be incident on the planar interface undergo total internal reflection at the planar interface, and the sample is disposed in the peripheral region contacting the planar interface of the irradiating mechanism. When the terahertz waves undergo the total internal reflection at the planar interface, the sample is irradiated with evanescent waves scattering from the planar interface to the peripheral region contacting the planar interface, so as to measure a spectrum.
