Abstract: In a room exit determination, a determination of presence of a body in a room is made if a movement pattern vector consisting of a room ID of movement origin, a room ID of movement destination and a movement period of time is not received from the a non-specified room response sensor within a predetermined period of time. A determination of exit from the room of a body is made only when the movement period of time in the movement pattern vector agrees with a movement period of time of past exits from the room stored in the a movement time storage if this vector is received from the non-specified room response sensor.

Abstract: In an adaptive control system, an input of an object to be controlled is varied by a small value, and a resultant output is detected. The small value is changed on the basis of the difference between the output and an aimed value, and trials are repeated. The small value is determined on the basis of a qualitative model which is composed of a boundary function including the input and boundary parameters of the object. If the trend in the difference between the output and the aimed value is to make it larger, the qualitative model is changed so that the trend is to make it smaller.

Abstract: In an adaptive control electrophotographic apparatus, input voltages such as illumination power source voltage and electrostatic charge voltage are varied by a small value, and a resultant density of toner image on a photoconductive substance is detected. Then the above-mentioned small value is changed on the basis of a difference between the resultant density and a target density. After several repetitions of the above, the small value is determined on the basis of a qualitative model which is composed of a boundary function including the input voltages and boundary parameters of the apparatus. If the trend in the difference between the resultant density and the target density is an increase, the qualitative mode is changed to effect a decreasing trend.
