A probe apparatus in combination with an endoscope includes a confocal laser probe for in-vivo imaging. The filter material is well suited to filtering liquid borne particulate matter ranging in size from 5 to about 25. The system and method autonomously estimates all screen variables from two inputs, those being the number of engines and maximum takeoff weight, and further allows a designer to override any variables relating to the EPGDS of the aircraft, including the configuration of the EPGDS. The device can be made by forming a sheet of the polymer over the curved contoured surface of the joint trial body and then adhering the sensor array to one curved contoured surface of the formed polymer. The frit sealing system further comprises a support apparatus configured to hold a first and a second substrate with frit interposed between them, wherein the frit is configured to be cured by heat generated from the laser beam and thereby solidifying and binding the first and the second substrates.
