Union Tool Co, a cutting tool manufacturer based in Japan, will release a system that monitors an elderly person, etc by using an LED lamp equipped with a laser device in September 2015.

The system, "Laser Light," can instantaneously detect abnormalities such as a tumble of the object person and monitor the state of breathing or sleeping by measuring the distance between the LED lamp attached to a ceiling and the object person. Different from monitoring systems equipped with a camera or biosensor, the new system can eliminate the discomfort and tension that are often caused by the feeling of "being watched" or "wearing a device."

Union Tool expects that the Laser Light will be employed for elderly and nursing facilities, aiming to achieve sales of ¥300 million (approx US$2.6 million) in the first year. It had a press conference Nov 10, 2014, to explain the new system.

CQ-S Net, a company that deals with remote nursing systems based on information and communications technologies, developed the Laser Light and obtained a patent for it. A milliwave (24GHz) radar device and a wireless LAN chip are embedded in a lighting apparatus. And the system measures the distance between the lamp attached to the ceiling and the head of an elderly person, etc by analyzing the reflected light of the radar device and transmits the results to a server via a wireless LAN.

When the object person hunkers down or falls over, the distance between the person and the ceiling suddenly changes. Then, the system notifies a caretaker or a family member who is in a remote place of the sudden change of the person's physical condition.
