ABSTRACT:
A novel portable light beam projector device, related system apparatus, and attendant novel method for wide variety use in conjunction with military vehicles, to establish optimum placement of optical fire detection sensors relative to installation of the vehicle's fire suppression system. These inventions are similarly usable to novelly establish corresponding optimum placement of various optical type intrusion and/or fire-detection sensors to similarly protect various confidential areas including storage facilities and attendant personnel/equipment/data and the like whether of a military, industrial or commercial character.
Each light projector device has an adjustable tubular shroud to adjustably focus the light beam cone angle. The desired cone angle of the light beam is initially set by use of associated system apparatus including an associated light beam calibration chart and some optional projector support stands. The cone angle adjustment feature enables the user to essentially duplicate the corresponding normally invisible field-of-view of various types of optical sensors to be installed. The related system apparatus further includes a part-time or selectively usable angularly adjustable bracket determining device for sensor installations requiring angular disposition relative to a vertical or horizontal structural component.
The inventions hereof greatly simplify, expedite, and assure highly accurate installations by eliminating the unsatisfactory former highly empirical character thereof, and large wasteful costs associated with the former practices.
