Only when the judgment result shows that the detection value x is not a sudden value change, a target luminance value y is calculated according to the detection value x.

The first computation unit carries out a first computation on a detected value which is detected from a control object and acquires a first result value.

The judgment section can change a threshold value to be compared with the detected value of the first sensor in accordance with the detected value of the second sensor, to judge the presence of the collision of the mobile body.

Then, an actual value of the parameter is detected, and an estimated accumulated quantity (Sa) and an estimated burned/fallen off quantity (Sb) that correspond to the detected value are determined by the storage means.

Communicating water content information may include processing the sensed water content value and comparing the value to one or more threshold values to qualify the sensed value.

Mass flow controllers (13a, 14a) are tested or corrected by the detected value.

When the value detected is largely different from a value detected before the start of motor drive, the sensor means recognizes the storage (3) is in collision with an obstacle, and the motor (6) is stopped driving.

The sensed value is then adjusted based on the offset value to produce an adjusted value representative of the thermal state of the battery.

A temperature at a position proximate the battery's cell is sensed during operation of the electronic system to produce a sensed value.

A magnetic value generated when a final output gear is rotated is detected through a hall sensor to reuse the detected value to control feedback.

A captured value (W1) of the hydrocarbon concentration (cHC) is measured using the sensor.

The position of the valve depends on a value detected by a temperature sensor.

The magnetic flux is detected using the distortion value, and the drive current is controlled using the detected value.

The judging means compares the corresponding temperature value memorized in the memory means and a value detected by the second temperature sensor.

A means (9) stores the deviation between the analogue signal to be converted and said first detected value.
