Method and apparatus for accurately determining an air quality level even when the temperature and humidity are varied can be achieved. A predefining formula used for obtaining the output value of an air quality level sensor according to the conditions of temperature and humidity at a clean state is obtained, the output value at the clean state of the air quality level sensor at a temperature and humidity at air quality detection using the formula is calculated a corrected amount as a difference between the calculated output value and an output value at the clean state of the air quality level sensor at conditions of temperature and humidity providing an absolute determination reference of the air quality level is taken, and the threshold value predetermined at the conditions of temperature and humidity providing an absolute determination reference is connected, by adding the correction amount to the threshold value, and determining an air quality level by comparing an output of the air quality sensor upon the air quality detection, with the corrected threshold value.

The present invention has an electrode for energization use of a thermal head having an unprecedentedly new electrode construction of a full peripherally surrounding type, so that one heating portion corresponds to one individual electrode without separation or independence of a heating resistor. Thus, the heating efficiency in the printing operation is improved to increase the thermal response property, thus making it possible to save the power. Furthermore, the full periphery surrounding electrode portion is adapted to be completely covered by the heating resistor to remove the dispersion of the resistance values of each dot responsible for the dispersion of the printing width of the heating resistor, and to completely provide uniformity by an energization overload trimming system. The heating efficiency and the thermal response property are improved, and the uneven printing concentration of each dot is removed to make the gradation recording property better, thus making it possible to have an embodiment of a thermal head capable of high-quality printing and having high reliability.

A primary object of the invention is to provide a method and system for detecting humans present in a restricted space, particularly, in a commuter train, a building, etc., by using an infrared sensor capable of detecting the presence of humans, and for judging the ratio of human occupancy in that space. To accomplish this object, according to the invention, the infrared sensor is installed, for example, on a ceiling near the center of a room, and the whole room space is scanned by the infrared sensor to detect in which region of the room a human is present. The proportion of human presence regions thus detected to the whole detection region is determined as the ratio of human occupancy. More specifically, a designated space is detected by the infrared sensor, and only human presence regions are extracted from that space; then, the ratio of human occupancy in the room is estimated from the ratio of the area of the extracted human presence regions to the area of the whole detection area.

A temperature distribution measurement apparatus has an infrared array sensor that includes a pyroelectric substrate with infrared array receiving electrodes and electrodes for compensation formed on its front side and opposing electrodes formed on its backside. Also included is an infrared lens to focus incident infrared lights on the array sensor, a chopper to cut off the incident infrared rays intermittently and a rotating part carrying and rotating parts of the apparatus. The detector elements of the infrared array sensor are laid out vertically and parallel with one another. A horizontal temperature distribution is measured by a lateral scanning with the rotating part rotating horizontally while a vertical temperature distribution is measured by driving the chopper in front of the infrared sensor. Thus, a two dimensional temperature distribution of an empty space is measured. The number and the position of persons in the empty space attained from the temperature distribution measurement data is useful for controlling air conditioners.
