Good morning, teacher and classmates. My name is Damian Pozo and I am an electricity student. Today I present to you a smart jacket for electricians designed to protect their health and safety. This garment has sensors that measure the worker’s heart rate in real time. If it detects that the pulse rises to a risky level, it activates strong vibrations in several parts of the jacket and automatically cuts the power to the electrical tool being used. The goal is to force the worker to stop and rest, preventing overexertion, dizziness, or accidents caused by fatigue. In addition, the jacket records the data and can connect with supervisors to act quickly in case of an emergency. --- 📄 Instructions for Use ✅ Positive Instructions 1. Fully charge the battery before starting the workday. 2. Wear the jacket adjusted to the body so that the sensors work correctly. 3. Pair the jacket with the cut-off module before turning on any tool. 4. Respect the vibration alerts and take breaks when the system indicates. 5. Periodically check the condition of cables, sensors, and batteries. 6. Store the jacket in a dry and cool place after use. --- ❌ Negative Instructions 1. Do not use the jacket in heavy rain or submerge it in water. 2. Do not attempt to manipulate or open the electronic module while it is connected to the power grid. 3. Do not ignore the vibrations or alarms: they are a sign of overexertion or risk. 4. Do not use the jacket in environments with corrosive chemicals that could damage it. 5. Do not charge the battery while the jacket is in use. 6. Do not lend the jacket without explaining its operation and verifying pairing with the cut-off module. --- ⚠️ Warnings Do not use in environments with corrosive liquids or aggressive chemicals that could damage the sensors or electronic module. Avoid places with extreme temperatures (<0 °C or >45 °C) that could affect the battery or sensors. Do not submerge in water or use under heavy rain without a waterproof cover. Do not use near intense radiofrequency sources (towers, powerful transmitters) that may interfere with wireless communication. --- That has been all. Thank you very much for your attention, goodbye.
