Abstract

A fall protection harness has a magnetic sensor coupled to it, and a computer processor is coupled to the magnetic sensor. Upon damage to the fall protection harness, the magnetic sensor senses the damage, the magnetic sensor generates a first signal to the computer processor, and the computer processor generates a second signal indicating the damage.

First claim

The invention claimed is:

1. A system comprising:
a fall protection harness;
a computer board comprising a radio frequency (RF) communication device coupled to the fall protection harness; and
a magnetic sensor coupled to the fall protection harness and the computer board comprising the RF communication device;
wherein the magnetic sensor is operable to detect damage to the fall protection harness;
wherein the magnetic sensor generates a first signal to the computer board comprising the RF communication device; and
wherein the computer board comprising the RF communication device generates a second signal indicating the damage; wherein the magnetic sensor comprises a magnet and reed contact material, the magnet in contact with the reed contact material; and wherein the computer board comprising the RF communication device is operable such that upon a fall by a person wearing the fall protection harness, the magnet separates from the reed contact material, the first signal is transmitted to the computer board comprising the RF communication device, and the computer board comprising the RF communication device generates the second signal indicating the fall.

2. The system of claim 1 , wherein the damage to the fall detection harness is caused by a fall by a person wearing the fall protection harness.

3. The system of claim 1 , wherein the fall protection harness comprises a strap, the strap folded over on itself into a folded over area, and the magnet and reed contact material are coupled to the strap within the folded over area.

4. The system of claim 3 , wherein the folded over area comprises a first surface area of the strap folded over on and in contact with a second surface area of the strap;
wherein the magnet is coupled to the first surface area and the reed contact material is coupled to the second surface area;
wherein upon the fall by the person, the first surface area separates from the second surface area, thereby breaking the contact between the magnet and the reed contact material; and
wherein the computer board comprising the RF communication device is operable to receive the first signal indicating the break in contact between the magnet and reed contact material and is operable to generate the second signal indicating the fall.

5. The system of claim 2 , wherein the first signal comprises an electromagnetic signal, and the electromagnetic signal causes one or more of a visual alarm to be illuminated and an acoustic alarm to be sounded.

6. The system of claim 1 , wherein the computer board comprising the RF communication device senses a voltage level beyond a threshold of variation voltage when the magnet and reed contact material are in contact, thereby indicating that the fall has occurred.

7. The system of claim 1 , wherein the computer board comprising the RF communication device senses a voltage level within a threshold of variation voltage when the magnet and reed contact material are not in contact, thereby indicating that no fall has occurred.

8. A system comprising:
a fall protection harness;
a computer processor coupled to the fall protection harness; and
a magnetic sensor coupled to the fall protection harness and the computer processor; wherein the computer processor is operable such that upon damage to the fall protection harness, the magnetic sensor senses the damage, the magnetic sensor generates a first signal to the computer processor, and the computer processor generates a second signal indicating the damage;
wherein the magnetic sensor comprises a magnet and reed contact material, the magnet in contact with the reed contact material; and
wherein the computer processor is operable such that upon a fall by a person wearing the fall protection harness, the magnet separates from the reed contact material and the first signal is transmitted to the computer processor, and the computer processor receives the first signal and generates the second signal indicating the fall.

9. The system of claim 8 , wherein the fall protection harness comprises a strap, the strap folded over on itself into a folded over area, and the magnet and reed contact material are coupled to the strap within the folded over area.

10. The system of claim 9 , wherein the folded over area comprises a first surface area of the strap folded over on and in contact with a second surface area of the strap;
wherein the magnet is coupled to the first surface area and the reed contact material is coupled to the second surface area;
wherein upon the fall by the person, the first surface area separates from the second surface area, thereby breaking the contact between the magnet and the reed contact material; and
wherein the computer processor is operable to receive the first signal caused by the break in contact between the magnet and reed contact material and generate the second signal indicating the fall.

11. The system of claim 8 , wherein the first signal comprises an electromagnetic signal, and the electromagnetic signal causes one or more of a visual alarm to be illuminated and an acoustic alarm to be sounded.

12. The system of claim 8 , wherein the computer processor senses a voltage level beyond a threshold of variation voltage when the magnet and reed contact material are in contact, thereby indicating that the fall has occurred.

13. The system of claim 8 , wherein the computer processor senses a voltage level within a threshold of variation voltage when the magnet and reed contact material are not in contact, thereby indicating that no fall has occurred.

14. A non-transitory computer readable medium comprising instructions that when executed by a processor execute a process comprising:
receiving a first signal from a magnetic sensor coupled to a fall protection harness, the first signal generated as a result of the magnetic sensor sensing damage to the fall protection harness; and
generating a second signal indicating the damage to the fall protection harness;
wherein the magnetic sensor comprises a magnet and reed contact material, the magnet in contact with the reed contact material; and
wherein the computer processor is operable such that upon a fall by a person wearing the fall protection harness, the magnet separates from the reed contact material and the first signal is transmitted to a computer processor, and the computer processor receives the first signal and generates the second signal indicating the fall.

15. The non-transitory computer readable medium of claim 14 , wherein the fall protection harness comprises a strap, the strap folded over on itself into a folded over area, and the magnet and reed contact material are coupled to the strap within the folded over area; and
wherein the folded over area comprises a first surface area of the strap folded over on and in contact with a second surface area of the strap;
wherein the magnet is coupled to the first surface area and the reed contact material is coupled to the second surface area;
wherein upon the fall by the person, the first surface area separates from the second surface area, thereby breaking the contact between the magnet and the reed contact material; and
wherein the computer processor is operable to receive the first signal caused by the break in contact between the magnet and reed contact material and generate the second signal indicating the fall.

16. The non-transitory computer readable medium of claim 14 , comprising instructions for sensing a voltage level beyond a threshold of variation voltage when the magnet and reed contact material are in contact, thereby indicating that the fall has occurred
