Abstract: Systems and methods for defect detection and position control are described herein. A method of performing position control on members in a device may comprise applying, by a deposition device, a fiducial mark to a first member of the device, and receiving, by a processing unit, from an image capture device coupled to the processing unit, an image of the first member. in various embodiments, the method may further comprise detecting, by the processing unit, the fiducial mark on the first member. In various embodiments, the fiducial mark may comprise ink.

Abstract: An infrared imaging sensor compatible with 2nd Generation Forward Looking Infrared (FLIR) Horizontal Technology Integration (HTI) B-Kit based sensors. In one example, the infrared imaging sensor includes a set of refractive opto-mechanical modules, including an afocal optical module, a receiver assembly, and backward- and forward-compatible electronics modules. The afocal optical module is configured to provide a plurality of different fields of view for the infrared imaging sensor. In one example, the sensor is configured for MWIR and LWIR imagery.

Abstract: A slurry polishing apparatus (100) comprises an assembly of an upper slurry input/output section (108), a polishing section (110), and a lower slurry input/output section (112). Each of the apparatus sections are individually detachable from the assembly to facilitate insertion and removal of a hydrodynamic or aerodynamic machine part having a complex surface shape such as a turbine fan (102). A plurality of upper slurry deflector blades (124) and lower slurry deflector blades (126) are removably attached to the polishing section (110), and positioned in the slurry flow path so as to direct the slurry mixture evenly over the entire surface of each respective fan blade (104), and corresponding exposed intermediary rotor surface (106). Because the high pressure slurry mixture flows evenly over the exposed fan surfaces, a consistent removal of metal stock is achieved across the entire polished surface.
