Abstract: A computer implemented method, apparatus, and computer program product for processing aircraft software parts. A crate containing an aircraft software part is received from a source. Signatures are validated for the crate and the aircraft software part. If the signatures are valid, the crate is unpacked. The contents of the incoming crate are displayed. The aircraft software part is unpacked. Responsive to a request to upload the stored part to a library in the aircraft software part management apparatus, a determination is made as to whether the stored part meets a policy. If the stored part meets the policy, the part is signed. The signed part is placed in a crate and is signed to form a signed crate wherein signatures for the signed aircraft software part and the signed crate are different from the set of signatures in the incoming crate. The signed crate is sent to the library.

Abstract: Systems, methods and apparatus are provided through which a collimator has one or more varying physical characteristics that have the effect of varying the absorption of electromagnetic energy from a low extent of absorption at a leading edge to the same extent of absorption as the remainder of the collimator. In some embodiments, the collimator has a tapered knife-edge. The varying absorption of electromagnetic energy at different points along the collimator reduce abrupt transitions of projection of the electromagnetic energy onto an electromagnetic energy detector, thereby reducing erroneous artifacts in an image generated by the detector.

The system includes a correction scheme including temporarily replacing a defective pixel with a linear interpolation of the defective pixel's surrounding neighboring pixel values, determining a local gradient based in part on the acquired image and a gradient kernel, and providing a correction value based on the local gradient to correct the defective pixel. The correction scheme is repeated a plurality of times as desired to correct all the defective pixels in the acquired image.

Abstract: A technique for selectively processing data from a digital detector includes determining an image area produced by orientation of a radiation source assembly. The assembly may include a radiation source and a collimator, which may be separately orientable. The image area is computed based upon the orientation of the radiation source assembly that projects a radiation beam towards an imaging plane. Image data from a detector within the imaging plane is selectively processed to improve computational efficiency. The system may also determine whether the image area falls within the imaging surface of the detector and inform an operator or inhibit an exposure if such is not the case.
