Target marking system
View Patent ↗A method of controlling a target marking system includes emitting a beam with a beam source associated with a target marker. The method also includes sensing movement of the target marker, and modifying operation of the beam source based on the sensed movement. Such modification changes a characteristic of the emitted beam.

a target marker, the target marker comprising
a beam source configured to emit a beam;
a motion sensor configured to sense movement of the target marker and to generate a signal indicative of the sensed movement, and
a controller in communication with the beam source and the motion sensor, the controller configured to modify operation of the beam source in response to changes in the signal generated by the motion sensor, wherein such modification changes a characteristic of the emitted beam and wherein the motion sensor comprises an image processor configured to determine movement of a field of view and to change the signal generated by the motion sensor based upon the determined movement of the field of view.
2. The target marking system of claim 1 , further comprising an imager, wherein the field of view is a field of view of a component of the imager.
3. The target marking system of claim 1 , wherein sensing movement of the target marker comprises sensing a linear movement including at least one of a horizontal component and a vertical component.
4. The target marking system of claim 1 , wherein the emitted beam is collinear with a first axis in a plane comprising the first axis and a second axis orthogonal to the first axis, and wherein a first component of the sensed movement is defined along the second axis.
