Japanese manufacturer Exsight Inc. has a new wearable sensor that'll let bosses keep tabs on employees working on hazardous job sites, able to detect when someone has fallen down and even withstand explosions (just the sensor, not the person). It works simply by watching for when a person hasn't moved for a preset period of time, ringing an alarm when it detects immobility to notify others nearby that the person needs assistance and transmitting the alert back to a receiver that can be placed up to 100 meters, or over 300 feet, away. If you're not incapacitated but still in trouble, you can also simply push a button on the sensor to sound the alarm or, you know, toss it out the window if you just want to freak out your boss.
