| PROBLEM TO BE SOLVED: To provide a method for measuring turbulence intensity of a horizontal axis wind turbine for obtaining an absolute value of a turbulence intensity by considering the effect of movement of a nacelle with little effect of a rotor. SOLUTION: In measuring turbulence intensity of the horizontal axis wind turbine 10, the nacelle 2 is placed upstream of the rotor 1 of the horizontal axis wind turbine; in that state, respectively measured values are obtained simultaneously from an anemometer 4 mounted on the nacelle and an acceleration sensor 5 fixed to the nacelle. An absolute value of turbine intensity is calculated on the basis of the measured values of the anemometer and the acceleration sensor. Thus, the absolute value of turbulence intensity is calculated in consideration of the effect of movement of the nacelle. COPYRIGHT: (C)2010,JPO&INPIT | ||||||

| PROBLEM TO BE SOLVED: To detect an impact force corresponding to an actual movement of a human body in a compact constitution easily without requiring an article target, by using an acceleration sensor attached to the human body for detecting an acceleration of the movement, etc. SOLUTION: A watch main body 11 is of the same size as a general wristwatch which can be wound around a wrist or the like by a wrist band, having an acceleration sensor 12 set thereinside. For instance, if the watch main body 11 is fitted to a right arm as a person's dominant arm when the person makes a punching motion, a voltage generated from the acceleration sensor 12 is detected as a '+' voltage when the person projects the arm. On the other hand, at a turning point when the arm is fully extended, the voltage is detected as a '-' voltage. A maximum speed of the punch and an acceleration peak value B detected by the acceleration sensor 12 are nearly proportional, and therefore the maximum speed of the punch can be detected on the basis of the acceleration peak value B. An impact force of the punch is calculated from the speed of the punch and a weight of the person. COPYRIGHT: (C)1997,JPO | ||||||

| PURPOSE: To actuate an air bag by deciding an amount of physical change of a vehicle based on a deceleration signal from a G sensor, in an air bag control device. CONSTITUTION: In a controller 9 of an air bag control device, a deceleration (-G) signal from a G sensor 15 is integrated to obtain a speed arithmetic value which is a physical change amount of a vehicle. When this speed arithmetic value exceeds a predetermined threshold value, an ignition signal to an inflater 8 is output to actuate an air bag 5. Here, the initial waveform width of the deceleration signal is longer at low speed time than at intermediate speed time. When the waveform width exceeds a predetermined time at intermediate speed time, a low speed is decided to transfer the threshold value so as to increase. In this air bag control device, even when the speed arithmetic value at low speed time and intermediate speed time resembles closely in the initial stage, decision is made by the initial waveform width of the deceleration signal. Thus by deciding a speed in the point of time earlier than in the past, the air bag 5 can be actuated. COPYRIGHT: (C)1993,JPO&Japio | ||||||
