Abstract

A method includes measuring raw sensor information of a tool over a period of time with a sensor tag coupled to an external surface of the tool. The method also includes determining one or more events of the tool based on the raw sensor information. The one or more events includes a free fall event of the tool. The method also includes calculating a free fall time and a free fall height based on the raw sensor information over the period of time. The method also includes wirelessly transmitting a history of the one or more events from the sensor tag to a remote computing device. The history includes the free fall event, the free fall time, and the free fall height of the tool.

First claim

What is claimed:

1 . A method, comprising:
measuring raw sensor information of a tool over a period of time with a sensor tag coupled to an external surface of the tool; determining one or more events of the tool based on the raw sensor information, wherein the one or more events comprises a free fall event of the tool; calculating a free fall time and a free fall height based on the raw sensor information over the period of time; and wirelessly transmitting a history of the one or more events from the sensor tag to a remote computing device, wherein the history comprises the free fall event, the free fall time, and the free fall height of the tool.

2 . The method of claim 1 , wherein the raw sensor information comprises a movement, a movement intensity, a touch, a pressure, a position, an orientation, a speed, a distance, a height, vibrations, acceleration, elevation, or a combination thereof.

3 . The method of claim 1 , wherein the one or more events comprises a movement, a usage, an idle time, a transportation, or a combination thereof.

4 . The method of claim 1 , wherein the remote computing device is a smartphone, a mobile phone, a tablet, a desktop computer or any processor-enabled device.

5 . The method of claim 1 , comprising determining damage inflicted on the tool based on the free fall event.

6 . The method of claim 1 , wherein the one or more events of the tool are calculated in real-time.

7 . The method of claim 1 , wherein the tool comprises a power tool, a measuring device, a direct fastening tool, a diamond cutting tool, a drilling tool, or any other construction tool.

8 . A system, comprising:
a sensor tag removably coupled to an external surface of a construction tool, wherein the sensor tag comprises: one or more sensors configured to measure raw sensor information of the tool over a period of time; a processor configured to determine one or more events of the tool based on the raw sensor information, wherein the one or more events comprises a free fall event of the tool, and wherein the processor is configured to calculate a free fall time and a free fall height based on the raw sensor information over the period of time; and communications circuitry configured to wirelessly transmitting a history of the one or more events from the sensor tag to a remote computing device, wherein the history comprises the free fall event, the free fall time, and the free fall height of the tool.

9 . The system of claim 8 , wherein the raw sensor information comprises a movement, a movement intensity, a touch, a pressure, a position, an orientation, a speed, a distance, a height, vibrations, acceleration, elevation, or a combination thereof.

10 . The system of claim 8 , wherein the one or more events comprises a movement, a usage, an idle time, a transportation, or a combination thereof.

11 . The system of claim 8 , wherein the processor is configured to determine damage inflicted on the tool based on the free fall event.

12 . The system of claim 8 , wherein the remote computing device is a smartphone, a mobile phone, a tablet, a desktop computer or any processor-enabled device.

13 . The system of claim 8 , wherein the tool comprises a power tool, a measuring device, a direct fastening tool, a diamond cutting tool, a drilling tool, or any other construction tool.

14 . The system of claim 8 , wherein the one or more events of the tool are calculated in real-time.
