In an embodiment, a method is provided for organizing semi-structured data having properties. is discharged to a side of a machine as a discharge airflow, the airflow can be prevented from blowing to trees located at the side of the machine and to walkers passing the side of the machine. Aspects of some methods include monitoring the output of a stabilized diode laser system to reduce noise of the output laser beam.
