Comfort Pressure Evaluation of Men's Socks Using an Elastic Optical Fiber:

In this work, factor analysis is used to study six adjectives for defining comfort in Japanese mens socks. Comfort consists of three common factors: Factor A is related to a tight feeling at the sole of socks and a cramped feeling, factor B is related to a close tit feeling, and factor C is related to a tight feeling at the top of socks and a comfortable feeling. Because the comfortable feeling is closely related to the tight feeling at the top, a system is developed to measure the clothing pressure at the top of the socks using an elastic optical fiber. The relation between the subjective evaluation of comfort and the clothing pressure as measured by the experimental system is then examined by correlation analysis. Because the clothing pressure at the sock top has a positive correlation with the tight feeling at the top and a negative correlation with the comfortable feeling, mens socks are judged loose at their tops and comfortable as the clothing pressure at the top decreases.

Non-invasive measurement system for human respiratory condition and body temperature

A special chromel wire (C) and alumel wire (A) thermo-pile has been developed which can measure human respiratory condition and body temperature without directly contacting a sensor to the human body. The measurement system enables high speed, real time, noninvasive, and simultaneous measurement of respiratory rates and body temperature with the same sensor. The special CA thermo-pile with a sensing each junction of approximately 25 /spl mu/m were constructed by using spot welded thermo-pile junction. The thermo electric power of 17 pairs of special CA thermo-pile is 0.7 mV//spl deg/C. The special CA thermo-pile provides high sensitivity and fine frequency characteristics, of which the gain is flat to approximately 10 Hz.<<ETX>>
