Patent ID: 8816849

Claim:
A device for signaling the presence of suspended or overhanging obstructions to a path of travel by an individual, comprising: a) a housing that can be worn by an individual; b) a first distance sensor on the housing that, when the housing is worn by the individual, is oriented to selectively detect a suspended or overhanging obstruction at an elevation above the housing; c) a second distance sensor on the housing that is oriented to selectively detect an object at the elevation of the housing; d) a logic circuit at the housing that is electrically connected to the first and second distance sensors, the logic circuit emitting a response if the first sensor above is activated, and not emitting a response if the first and second sensors are both activated; and e) a signaling device at the housing and electrically connected to the logic circuit, whereby the signaling device is activated by a response from the logic circuit, thereby selectively signaling the presence of a suspended or overhanging obstruction, wherein the signaling device includes a tactile feedback component that emits a signal, the strength of the signal being inversely proportional to the distance between the housing and the obstruction.
