  • Overhang warning device
    Patent number: 8816849
    Abstract: Suspended or overhanging of obstructions are selectively signaled to an individual by a device that can worn by an individual. The device includes a first sensor that is oriented to selectively detect a suspended or overhanging obstruction at an elevation above the housing and a second distance sensor that is oriented to selectively detect an object at an elevation of the housing. A logic circuit within the housing is electrically connected to the first and second sensors and emits a response if the first sensor is activated, but emits no response if the first and second sensors are both activated. A signaling device electrically connected to the logic circuit is activated upon emission of a response from the logic circuit.
