摘要:
An apparatus for estimating a drowsiness level of a vehicle driver first prepares a frequency distribution of blink durations of the driver for a first predetermined period after the start of a driving operation, and sets a threshold value for a discrimination of slow blinks by the frequency distribution. Thereafter, the apparatus calculates, every second predetermined period, a ratio of the number of slow blinks to the total number of blinks of the driver's eyes during the second period, and discriminates a rise in the drowsiness level of the driver in accordance with the calculated ratio.

The present invention provides a high-temperature shape memory alloy, in which Hf, Zr, Ta, Nb, V, Mo, and W as a third element except Ni are added to TiPd to thereby improve high-temperature strength and exhibit large shape recovery in a high-temperature range of 200° C. to 500° C., and a method for producing the high-temperature shape memory alloy.
摘要:
A gas sensor contains such a dielectric substance having a domain boundary formed between domains with different polarization directions. When a gaseous molecule is adsorbed to the dielectric substance, a transient current is generated due to displacement of the domain boundary under an applied voltage. The adsorbed gaseous molecule is detected by measuring the transient current.
摘要:
Driving attentiveness judging method and apparatus for accurately determining the driver's attentiveness level during driving of a motor vehicle are provided wherein steering angle data and vehicle speed data, respectively supplied from a steering angle sensor and a vehicle speed sensor, are sampled by a steering angle data sampling section and a vehicle speed data sampling section, respectively. Respective levels of road shape component, visual steering component, and corrective steering component of the steering angle data are detected by a steering angle data processing section, and a fuzzy inference output representing a driving attentiveness level is obtained by a fuzzy inference section in accordance with fuzzy rules and the three steering component levels. In accordance with the fuzzy inference output which has been subjected to vehicle speed-dependent correction by a vehicle speed correcting section, the driving attentiveness level is displayed at a display device, and also a warning mark is displayed if the vehicle speed-corrected fuzzy inference output is small.
