Abstract: A cellular phone and personal protective equipment usage system comprises a camera for detecting a person within an environment and a processor which receives information detected by the camera and determines whether the person is involved in distracting activities such as using a cellular phone or other portable electronic device, or print media, or is using personal protective equipment, and issues an alarm signal upon determining that the person is using a cellular phone or is not using personal protective equipment. The camera may be provided on or within a vehicle and the person is an operator of the vehicle. Alternatively, the camera may be mounted in a stationary location within a working site.

Abstract: A system for determining a vehicle operator's level of fatigue comprises a camera for detecting at least the vehicle operator's eyes; an onboard vehicle detector for detecting at least one of vehicle speed, location, activity, acceleration, deceleration, or steering wheel rotation; and a processor which receives information detected by the camera and the onboard vehicle detector and calculates a real-time operator fatigue score based on the received data. The operator fatigue score may further be based on an operator's time of shift, type of vehicle, and current and previous tasks.
