Systems and methods of automatically adjusting brightness of a digital image are provided. A particular method includes accessing data including a first digital image and identifying text and background in the first digital image. The method also includes calculating an average pixel value exclusive of the text and the background for the first digital image. The method further includes adjusting a brightness setting associated with the first digital image based on the calculated average pixel value.

System and method for comparing images with different contrast levels

Apparatus, systems, and methods for inspecting a structure are provided which permit inspection of uniquely shaped structures such as fuselage frames and shear ties. Probes may be constructed from rapid prototyping. Inspection may be performed manually and may use a portable function support system for delivering fluid couplant, controlling transmit and receive functions of the inspection sensors, and delivering immediate visual analysis for an operator. Integrated ultrasonic inspection apparatus, systems, and methods facilitate fast and efficient custom inspection devices and inspecting otherwise difficult-to-inspect structures.

Integrated ultrasonic inspection probes, systems, and methods for inspection of composite assemblies

Methodologies and systems to compare images with different levels of contrast are provided. Contrast is normalized between the images with different contrast levels and brightness is set. When normalizing contrast a derivative of gray level is determined for a first digital image having a first contrast level, and a derivative of gray level is determined for a second digital image having a second contrast level that is greater than the first contrast level. A ratio of the derivative of gray level for the first digital image to the derivative of gray level for the second digital image is determined, and the derivative of gray level for the first digital image is equalized with the derivative of gray level for the second digital image. Brightness of at least one image may be set automatically, such as by calculating an average pixel value excluding background and text, or manually.

A system and method for inspecting a structure are provided. The system includes at least one non-destructive inspection ('NDI') sensor capable of acquiring data indicative of at least a portion of the structure, and at least one positional sensor for acquiring positional data of the NDI sensor. The system also includes a mechanism operable to trigger the NDI sensor and/or the positional sensor to acquire data such that data indicative of the structure and the positional data are acquired at approximately the same time. The system further includes a movable arm carrying the sensors and movably attached to a base. The system includes a data acquisition system capable of communicating with the sensors such that the data acquisition system generates information indicative of at least a portion of the structure based on the data acquired by the sensors.

Inspection system and associated method

An apparatus for the ultrasonic testing of internal areas of prefabricated composite assemblies as described. The composite assemblies have one or more internal areas formed therein. The apparatus includes at least one receive transducer, at least one transmit transducer, a vertical member, a support member slidably attached to the vertical member, a pair of substantially parallel hollow rods, and an ultrasonic testing system. Each rod comprises a transducer attachment end with receive transducers attached to the transducer attachment end of a first rod, and transmit transducers attached to the transducer attachment end of a second rod. The rods are slidably attached to the support member and manually movable with respect to a composite assembly to be tested. The ultrasonic testing system is coupled to the receive transducers through the first rod, and coupled to the transmit transducers through the second rod.

Methods and systems for inspection of composite assemblies

A digital bond tester operating at frequencies in the kHz range and relying upon vibrational modes which can excite all or substantial portions of the test object.

Digital bond tester

A container for holding food. The container includes cylindrical side walls fixedly mounted atop a bottom wall. A externally threaded post is rotatably and removably mounted atop the bottom wall and is in meshing engagement with a horizontally extending food supporting wall which sealingly engages the interior surface of the side walls. The top end of the threaded post is reduced in configuration and keyed to receive an external tool to facilitate the rotation of the post allowing the food supporting wall to be moved upwardly maintaining the food level adjacent the top of the container as food is withdrawn therefrom. A second tool removably mounted to the top end of the post allows the post and food supporting wall to be pulled upwardly and removed from the container.
