Abstract

A ladder including sensors is provided. A remote computing device is also provided that communicates with the sensors to facilitate detection of various operating conditions. Methods for detection are also provided.

Claims (23)

1. A ladder comprising:

a pair of rail members, each rail member comprising a respective foot portion;

at least one step extending between the pair of rail members;

a foot member coupled with the foot portion of one of the rail members;

a foot pad configured to engage a ground surface;

a power module;

a sensor module coupling the foot member to the foot pad, the sensor module comprising a Hall effect sensor configured to detect deflection of the foot member relative to the foot pad in response to load on the one of the rail members being transmitted through the sensor module;

a control module in electrical communication with each of the power module and the sensor module and configured to process sensor data from the sensor module; and

a wireless communication module in electrical communication with each of the power module and the control module, wherein the wireless communication module is configured to facilitate wireless communication with a remote computing device.

2. The ladder of claim 1 further comprising a printed circuit board having mounted thereon at least two of the power module, the control module, and the wireless communication module.

3. The ladder of claim 2 wherein the printed circuit board is disposed adjacent to the foot portion.

4. The ladder of claim 1 wherein the communication module is configured to facilitate wireless communication via a Bluetooth protocol.

5. The ladder of claim 1 wherein the power module comprises one or more of a battery, a photovoltaic cell, and a charging port.

6. The ladder of claim 1 further comprising an alert module that is configured to generate an alert upon detection of a hazardous condition.

7. A ladder comprising:

a pair of rail members;

at least one step extending between the pair of rail members; and

a monitoring device comprising:

a means for providing electrical power;

a means for sensing a load on at least one of the rail members, wherein the means for sensing comprises a Hall effect sensor;

a means for processing signals resulting from the sensing of the load; and

a means for wirelessly communicating data in response to the processing of signals, wherein the means for wirelessly communicating comprises a Bluetooth communication module.

8. The ladder of claim 7 wherein the monitoring device further comprises a means for alerting a user of a detected hazardous condition.
