Smart rooms and elevators
From Engadget, The violence-detecting elevator, links to Japan Today
Mitsubishi Electric Building Techno-Service Co said Tuesday it has developed a surveillance camera system that can detect violent acts and other abnormal behavior inside elevators.
A control device built into the camera divides an image of the elevator into up to 4,800 frames. When abnormal behavior, such as somebody punching another person, takes place inside the elevator, the device optically reads changes in the frames, recognizes them as resulting from irregular behavior and opens the elevator's door at the next floor.
Another similar concept, but different technology for prison cells was noted in Security Park
Holding cells fitted with specially-adapted sensors could provide early warnings if inmates become agitated or have a medical emergency. The sensors monitor movements in the cells, as well as inmates' vital signs such as respiration and heart-rate. If the sensor alarms and the police station is empty, a neighbouring police station is alerted by GSM.
The sensors - developed by Finnish company Emfit - are made of a nano-modified polymer film. The same technology is also being used to develop a cot that can keep a watchful eye on baby. In this case, a sensor is fitted to or under the mattress. Unlike sensors already on the market that can only sense a baby's weight, these sensors monitor breath and heartbeat. If the sensor alarms, an embedded GSM phone could alert the carer.
