Abstract:
A stairway safety system and method including movement sensors and/or force sensors, a safety button, a central processing unit, a user notify device configured to generate audio or visual indications prompting the stairway user to engage the safety button, and a communication device configured to send a message requesting help. The central processing unit is configured to measure the length of time between detecting signals from the sensors and also to instruct the first user notify device to generate audio or visual indications when the measured time between detecting the signals is shorter or longer than a stairway user's actual or estimated typical travel time through the stairway. The central processing unit is configured to measure time and to instruct the communication device to send the message requesting help if a safety signal is not detected within a safety time period which indicates a request for help may be needed.
