Abstract: The present disclosure is generally directed to of method linear feature detection in a structure by providing a first digital image of the structure, creating a second corresponding digital image of the structure from the first digital image and determining a direction to shift pixels of the second corresponding digital image. A pixel shift value may be input to shift pixels of the second corresponding digital image, and pixels of the second corresponding digital image are shifted by the input pixel shift value in the determined direction. A third corresponding digital image of the structure may be calculated by subtracting the second corresponding digital image of the structure from the first digital image of the structure.

Abstract: A configurable performance module for use in an integrated circuit. The configurable performance module includes a performance control circuit which controls a performance level of the integrated circuit to enable changing the performance level of the integrated circuit from a first performance level to a second performance level after manufacturing of the integrated circuit is complete.

Abstract: A method and system of determining the physical dimensions and configuration of a structure or system as a precursor to the design of modifications of the structure or system by analyzing hidden objects within the structure or system is provided. The method includes accessing the structure or system prior to the modification for preparation of the modification; scanning the structure or system with an x-ray backscatter unit; collecting data from the x-ray backscatter unit and combining and reconstructing the data into a 2-D, 2-D panoramic or 3-D data set; producing surfaces and structures of the hidden objects from the data set; and tying the surfaces and structures of the hidden objects into a pre-existing coordinate system of the structure or system creating a 3-D model.

Abstract: A system and methods for x-ray backscatter reverse engineering of structures. One embodiment includes a plurality of articulated arms attached to a movable base. Another embodiment includes a single counterweighted arm attached to a movable base. The arms include x-ray detectors. At least one x-ray source, which may be mounted on the arm(s), emits x-rays, which are backscattered off the surfaces and objects of interest and captured by the detectors to generate images of hidden objects. The present system provides improved speed and resolution over prior art systems. The system has a field-of-view and effective scanning range versatile enough to work in various orientations and in environments of various sizes. In certain embodiments the system is compact and lightweight so that it can be easily transported and used within confined spaces or in environments where weight is a consideration, such as inside or underneath aircraft. The system is also pointable and adaptable.

Abstract: An X-ray imaging system is provided which includes an X-ray tube including, a cathode for emitting electrons; and a dynamic anode. The dynamic anode receives the electrons from the cathode and generates an X-ray beam that is non-stationary. The dynamic anode rotates between a first position where the X-ray beam is directed at a first location on an object and a second position where the X-ray beam is directed at a second location on the object to generate the non-stationary beam.

Abstract: The remote control stand is designed to stand at 38 inches high. A circular base of 8-inches diameter and 1 (one) inch thick, weighing five pounds, sits flat on the ground. A stem of 38-inches rises from the center of the base and projects perpendicular to the base plane. (Thirty two) 32 inches above the base are two tubular pieces which project 4 inches on either side of the stem. These branches each hold an oval plate of about 6 inches long. The tips of these ovals point upwards and are recessed in the middle with a telephone-jack-type housing. Two elastic telephone-type cords of about 10-feet long anchor from the oval plate to the remote controls being secured. The remote controls rest on the ovals when they are not in use. This device as described in this abstract, the concert of elements to function in like manner, is the invention of William T. Edwards.

Abstract: A portable computer system including wireless communication functionality and global geographic positioning functionality includes a processor coupled to a wireless module, and a global positioning unit coupled to the wireless module and the processor. The wireless module may communicate with a wireless network via a wireless connection. The global positioning unit may be configured to receive geographic location information and to determine a current geographic location of the portable computer system based upon the received geographic location information. The processor may execute system software that may be configured to reconfigure system configuration settings such as security and authentication settings, and system clock settings, for example, dependent upon changes in the current geographic location information. In addition, an authenticated administrative level user may send one or more commands to the wireless module. The commands may cause a system storage to be made unreadable.
