Treadmill safety warning and notification system
Methods and systems are disclosed to detect whether a treadmill user is in the danger of falling off the treadmill and to accordingly warn the user via, e.g., audio and haptic feedback. In the event the runner falls off the treadmill and becomes hurt or unresponsive, the system can automatically notify emergency contacts, e.g., via phone calls or text messages.
1. A system for use with a treadmill to detect improper positioning of a user with respect to the treadmill, comprising:
a proximity device removably fixed to the treadmill, said proximity device including a proximity sensor configured to constantly detect a distance between the user and the proximity device when the user is using the treadmill;
a user device wirelessly connected to the proximity device to constantly receive data from the proximity device indicative of the distance between the user and the proximity device, said user device including a processor programmed to:
(a) process the data received from the proximity device to detect whether the user is in an improper position on a belt of the treadmill based on a plurality of zones on the belt of the treadmill, wherein the plurality of zones on the belt of the treadmill includes a first normal operation zone, a second danger zone in which the user is at heightened risk of inadvertently falling off the treadmill, and a third caution zone between the first zone and the second zone, and wherein an alert to the user indicates whether the user is in the second zone or the third zone;
(b) output the alert to the user when the user has been detected to be in an improper position; and
(c) automatically issue a notification to a person other than the user to notify the person of a possible emergency involving the user when the user fails to dismiss the alert within a predetermined time period.
2. The system of claim 1 , wherein the plurality of zones on the belt of the treadmill is predetermined.
3. The system of claim 1 , wherein the plurality of zones on the belt of the treadmill is calibrated by the user using the user device.
4. The system of claim 1 , wherein the notification comprises a text message, an email, a phone call, or an alert on a social network.
5. The system of claim 1 , wherein the proximity sensor comprises an ultrasonic sensor, an infrared sensor, an optical sensor, a radar sensor, or a capacitive sensor.
6. The system of claim 1 , wherein the user device comprises a smartphone, a tablet, a television, or a wearable smart device.
7. The system of claim 1 , wherein the user device includes a gyroscope or accelerometer to correct data received from the proximity device due to bouncing movement by the user during use of the treadmill.
8. The system of claim 1 , wherein the alert comprises a visual output, an audio output, a haptic output, or an electronic message output.
9. A method of detecting improper positioning of a user on a treadmill, comprising the steps of:
(a) constantly detecting a distance between the user and a proximity device removably affixed to the treadmill when the user is using the treadmill;
(b) wirelessly transmitting data indicative of the distance between the user and the proximity device from the proximity device to a user device;
(c) processing the data received from the proximity device on the user device to detect whether the user is in an improper position on a belt of the treadmill based on a plurality of zones on the belt of the treadmill, wherein the plurality of zones on the belt of the treadmill includes a first normal operation zone, a second danger zone in which the user is at heightened risk of inadvertently falling off the treadmill, and a third caution zone between the first zone and the second zone, and wherein an alert to the user indicates whether the user is in the second zone or the third zone;
(d) outputting the alert to the user when the user has been detected to be in an improper position; and
(e) automatically issuing a notification to a person other than the user to notify the person of a possible emergency involving the user when the user fails to dismiss the alert within a predetermined time period.
10. The method of claim 9 , wherein the user device includes a gyroscope or accelerometer to correct data received from the proximity device due to bouncing movement by the user during use of the treadmill.
