Non-contact elevator call button |
摘要 |
An elevator call button transmits infrared radiation into the space adjacent an elevator, and a call request is recognized by infrared radiation reflected from a potential passenger to an infrared receiver. Thus not only is contact with the button not required, the use of a finger or like-sized object is not required in order to place a call.
