Patent attributes
A laser generating device including a housing and a laser module assembly. The laser module assembly is at least partially housed in the housing. The laser module includes a pendulum assembly which rotates under the effects of gravity and a laser module on the pendulum assembly. The laser module includes a laser generator which generates a laser beam. The laser generating device also includes a pendulum lock which is movable from an unlocked position to a locked position. When the pendulum lock is in the locked position, it prevents the pendulum assembly from rotating. A sensor is provided to detect a freefall condition. The pendulum lock moves from the unlocked position to the locked position when the sensor detects the freefall condition.
