Recently Asahi News reported the following:
Nissan Motor Co., together with the measurement control equipment making company Chino (Tokyo) had jointly developed a small equipment as a means to deal with the new influenza. It could in three seconds measure the temperature of people visiting office buildings and communal facilities etc. The heat image sensor technology developed by Nissan for the car was applied. When the sales was started in September, about 300 were sold to major companies in one month, and the sales target by the end of the current year was 5,000. When the face was brought close up to 15 centimeters, the temperature of the body surface would be measured. If the temperature was 38-degree or more, a red lamp would blink, and the warning sound would be activated. According to Chino, the price would be about 300,000 to 400,000 yen cheaper than the equipment for measuring body temperature used in airports etc (costing about 1 million to 5 million yen).
After reading the above I think major commercial buildings in Hong Kong could consider installing similar machines to help fighting the next round of influenza.
