A pixel unit comprising a first metal layer and a second metal layer. Further, the flashlight of the present invention includes a novel modular interface arrangement that allows the flashlight to be interfaced with a variety of different equipment or reconfigured in order to facilitate use for different functionality such as a marker light, a runway indicator light or a weapon mounted light. For convenient storage, the first and second ramp sections fold with respect to each other and preferably retract into the vehicle floor such that, in the folded configuration, the top surface of the second ramp section lies substantially in the same plane as the vehicle floor. The method and system include generating an optimizer query for the external data source utilized by the query. The present invention includes multiple embodiments of axial, radial, and circumferential fuel staging within a can-type combustor having alternate ignition techniques of spark ignition or torch ignition.
