Fall protection radio frequency emergency beacon
Embodiments relate generally to systems and methods for quickly detecting a fall and alerting appropriate parties of the fall. A fall protection device may comprise a fall detection module operable to sense when a fall occurs and generate wireless beacon, where the beacon may be received (or picked up) by any number of wireless devices, including wireless gateways, monitoring stations, and mobile devices.
1. A fall safety device comprising:
a harness operable to be worn on a user's body;
an attachment point operable to attach the harness to a secure structure;
a fall cushioning element operable to be attached to the attachment point through a lanyard, wherein the fall cushioning element is configured to expand, stretch, or unfold in response to a fall;
a sensor attached to the fall cushioning element, wherein the sensor is operable to detect stretching and expanding of the fall cushioning element; and
a wireless module in communication with the sensor operable to receive data from the sensor indicating a fall and generate a wireless beacon forwarding sensed information to a wireless device, the wireless device being a mobile device carried by a user, wherein the mobile device is operable to forward an additional information to a monitoring station, the additional information comprising at least one of motion data collected by the mobile device and biological information.
2. The fall safety device of claim 1 , wherein the fall cushioning element comprises a shock absorber located between the attachment point and the harness.
3. The fall safety device of claim 2 , wherein the shock absorber is incorporated into the lanyard.
4. The fall safety device of claim 1 , wherein the fall cushioning element comprises a break-away strap located on the harness.
5. The fall safety device of claim 1 , wherein the wireless module generates a radio beacon operable to be received by any wireless device within the range of the wireless beacon, including mobile devices, wireless gateways, and monitoring stations.
6. The fall safety device of claim 5 , wherein the radio beacon is received by the mobile device carried by the user, and wherein the mobile device is operable to forward the radio beacon to the monitoring station, and wherein the motion data collected by the mobile device includes motion of the user before, during, and after the fall, and the biological information includes heart rate information.
7. The fall safety device of claim 1 , wherein the sensor and wireless module are housed together in a fall detection module.
8. A method for detecting a fall event comprising:
sensing a stretch or expand of a fall cushioning element when a fall occurs, wherein the fall cushioning element is part of a fall safety device;
receiving sensed information to a wireless module;
generating, by the wireless module, a wireless beacon based on the sensed information; and
broadcasting the wireless beacon to other wireless devices, wherein the wireless beacon is forwarded to a monitoring station;
receiving, by a mobile device carried by a user, the wireless beacon;
forwarding, by the mobile device, the wireless beacon to the monitoring station; and
sending, by the mobile device, additional user information with the wireless beacon, the additional user information comprising one or more of motion data collected by the mobile device, and biological information.
9. The method of claim 8 , wherein the motion data collected by the mobile device includes motion before, during, and after the fall, and the biological information includes heart rate information.
10. The method of claim 8 further comprising: when the fall safety device is worn by the user, and the fall has not occurred, generating an update from the wireless beacon indicating health and operation of the wireless beacon; and broadcasting the update to other wireless devices, wherein the update is forwarded to the monitoring station.
11. The method of claim 10 , wherein generating the update occurs periodically throughout the life of the wireless module.
12. The method of claim 8 , wherein the fall cushioning element comprises a shock absorber, and wherein the stretch or expand of the shock absorber is sensed by a sensor attached to the shock absorber.
13. The method of claim 8 , wherein the fall cushioning element comprises a break-away strap, and wherein the stretch or expand of the break-away strap is sensed by a sensor attached to the break-away strap.
14. The method of claim 13 , wherein the sensor and wireless module are housed together as a fall detection module.
15. The method of claim 8 , wherein the wireless beacon is operable to be received by any wireless device within the range of the wireless beacon, including mobile devices, wireless gateways, and monitoring stations.
16. A method for detecting a fall event comprising:
periodically generating an update from a fall detection module indicating health and operation of the fall detection module, wherein the fall detection module comprises a sensor and a wireless module;
broadcasting the update to other wireless devices, wherein the update is forwarded to a monitoring station;
sensing, by the sensor of the fall detection module, a stretch or expand of a fall cushioning element when a fall occurs, wherein the fall cushioning element is part of a fall safety device;
receiving sensed information to the wireless module;
generating, by the wireless module, a wireless beacon based on the sensed information;
and broadcasting the wireless beacon to other wireless devices, wherein the wireless beacon is forwarded to the monitoring station;
receiving, by a mobile device carried by a user, the wireless beacon; and
forwarding, by the mobile device, the wireless beacon to the monitoring station; and
sending, by the mobile device, additional user information with the wireless beacon, the additional user information comprising at least one of motion data collected by the mobile device, and biological information.
17. The method of claim 16 , wherein the motion data collected by the mobile device includes motion before, during, and after the fall, and the biological information includes heart rate information.
18. The method of claim 16 , further comprising: when the fall safety device is worn by the user, and the fall has not occurred, generating an update from the wireless beacon indicating the health and operation of the wireless beacon, wherein generating the update occurs periodically throughout the life of the wireless module; and broadcasting the update to other wireless devices, wherein the update is forwarded to the monitoring station.
