Optical interface cards, assemblies, and related methods, which may be suited for installation and use in antenna system equipment, are disclosed. A method for treating diabetes and related diseases employing the above compounds is also provided. The method separates data independent operations from data dependent operations wherein multiprocessing may be efficiently utilized for processing data independent macroblocks. The camera is rotatably assembled on the other end of the first connecting beam, and the other end of the third connecting beam rotatably is connected to the main body. At least one nanoelectromechanical dielectric perturber produces \xb145\xb0 birefringent axes by placing the at least one nanoelectromechanical dielectric perturber at selective positions around the phase retarder to produce dynamic change in the effective index in one of the modes existent in an extraordinary axial direction. In time of the reconstruction process, a corrected parameter is applied to the reconstruction algorithm for correcting a mechanical displacement occurring between the axis of revolution of the X-ray tube and FPD and the axis of X-ray emission.
