HAZARD MARKER

摘要

A hazard marker is disclosed. The hazard marker utilizes a series of illumination devices (e.g., LEDs) positioned to generate a highly visible light pattern. The hazard marker includes a motion detector and transmitter to alert users that the hazard marker has been moved in a pre-established manner (e.g., thirty degrees off horizontal). As a result of being moved in the pre-established manner, a signal transmitted by the hazard marker triggers an alarm in a receiver held by a user (e.g., police officer). The alarm alerts the user that a safe zone defined by a series of hazard markers has been breached or a hazard marker is being physically moved and possibly stolen.
