Recently, according to Japan’s Kyodo News Agency, Japan’s Ministry of Land, Infrastructure, Transport and Tourism has basically decided on the 1st that automakers must install "sports approaching vehicles" on vehicles that use small sounds such as hybrid vehicles (HVs) that use less sound to tell pedestrians approaching. Device". The device will be applied to hybrid vehicles, electric vehicles (EVs) and fuel cell vehicles, which are powered by electric motors, in the first 2018, according to international standards such as the volume of the United Nations agencies introduced around March. The move aims to strengthen safety measures for pedestrians and bicycles such as the elderly and children, and will amend the safety standards of the Road Transport Vehicles Act. New cars that are not equipped with international standard devices will not be sold in Japan. Used cars, etc. are not covered by this regulation. It has been pointed out that motor-powered cars are smaller than engine cars at low speeds, and pedestrians may not be aware that the car is approaching and there are safety hazards. In January 2010, the Ministry of International Affairs of the People's Republic of China established a directive on proximity notification devices and urged manufacturers to install them. The price of the device used by the Toyota Motor Corporation in the summer of 2010 is about 12,000 yen (about 654 yuan). According to the Ministry of International Trade, the devices are currently standard on hybrid vehicles, electric vehicles and fuel cell vehicles sold by various manufacturers. The international standards are developed by Japan and Europe. The volume and audio of the notification sound are displayed numerically, and the conditions that are easy for the pedestrian to distinguish are emphasized. No specific numerical standards have been written in the current guidelines of the Ministry of International Affairs, and will be further strictly regulated in the future.
Hot Mirror : Reflect IR Cold Mirror: Reflect Visible
A cold Mirror is a specialized Dielectric Mirror, a Dichroic Filter, that reflects the entire visible light spectrum while very efficiently transmitting infrared wavelengths. Similar to hot mirrors, cold mirrors can be designed for an incidence angle ranging between zero and 45 degrees, and are constructed with multi-layer dielectric coatings, in a manner similar to interference filters. Cold mirrors can be employed as dichroic beamsplitters with laser systems to reflect visible light wavelengths while transmitting infrared.
