Abstract: According to an embodiment, a method and system for color calibration in a three-dimensional multi-color laser scanning system is disclosed. An object may be scanned with the scanning system, which scans the object with color laser heads. Laser intensities, corresponding to laser intensity values, may be received from the scanned object. Three different calibration targets are used to setup a field of view (FOV) calibration profile due to scanning position changes, a surface normal calibration profile due to surface normal direction changes, and a color reflectance calibration profile due to color reflectance changes. After compensating for laser power drift fluctuations, the laser intensity values may be further compensated for field of view scanning position changes and surface normal direction changes using the field of view calibration profile and surface normal calibration profile.

Abstract: An electric furnace comprising an integral front panel containing a plurality of louvers. The interior of the furnace contains a flow channel to direct air towards the top of the furnace. At least some of the louvers will direct air into the flow channel. The air is then conditioned and delivered back to the home.

Abstract: A molded drain pan for use with a conditioning system. The drain pan has an inner and outer wall and a bottom creating a donut shaped annular pan to collect condensate. The pan contains a thin support rib, which is inclined to direct condensate towards a drain. The thin rib reduces heat transfer between the pan and a support structure.
