The invention provides a stretching and compression stress wave generator based on electromagnetic force and an experimental method. The stress wave generator is such structured that a capacitor charger is connected with a loading gun. A main coil, an insulating layer and a secondary coil all sleeve the locating shaft of a tapered amplifier.

A set of complex rotations are used to implement a unitary “Q” matrix that can arise in various transmitters and / or receivers in communication line vectoring. Each complex rotation is a set of real rotations, where the minimum number of real rotations to perform the complex rotation is three, and where the minimum number of angles to characterize the real rotations is two. An order of rotations is also provided. The invention assists in the efficient implementation of any unitary “Q” matrix in a QR or other sophisticated matrix factorization. A complex form of the so-called “Givens” implementation of the Q matrix is characterized in terms of a sequence of complex rotations that can implemented using a complex rotor computational unit that accepts a minimum of two real angles and a pair of integer indices for each of a set of successive complex rotor calculations and then implements the complex rotation as a series of a minimum of three real rotations with one real angle used twice and the other real angle used once, providing two complex outputs (that is, two rotated data entries from a data vector comprising indexed communication data) for two complex inputs (two original data entries from a data vector comprising indexed communication data). The index-angle sets for each successive rotation can be provided by a complex rotor calculation unit, which may be collocated with the complex rotor computational unit, located in a controller such as a DSL optimizer, or located in any other suitable device or apparatus that has performed the QR factorization upon supplied matrix MIMO transfer functions for the vectored channel.

In one aspect of the invention, a method provides a calibrated critical-failure model for a printing process of a critical feature by virtue of a classification of an optical parameter space according to at least two print-criticality levels. Print failure of a respective critical feature is judged on the basis of a print-failure criterion for the critical feature. The respective print-criticality level is ascertained from test-print-simulation data at a sampling point of a process window for a given point in an optical-parameter space, and from a failure rule. An advantage achieved with the method is that it comprises ascertaining the predefined optical-parameter set from the test-print-simulation data at only one sampling point of the process window, which sampling point is identical for all test patterns. This saves processing time and processing complexity by reducing the number of ascertained optical-parameter sets and their processing in the subsequent scanning and classifying steps.

The invention proposed a Dual-Pulse Excitation Model; wherein two pulses of each pair of pulses are always adjacent each other. Only one position index for each pair of pulses needs to be sent to the decoder, which saves bits to code all pulse positions. The magnitudes of each pair of pulses have limited number of patterns. Because the two pulses are adjacent each other, each pair of pulses with different magnitudes can produce different high-pass and / or low-pass effect. Since the magnitudes have enough variation, it is possible to assign the candidate positions of each pair of pulses within a small range in order to save the searching complexity.

A method is presented for a 3D inspection of an object or bag in order to check for explosives or contraband. The method is applicable to Computed Tomography, Laminography or any other method that can be used to produce images of slices through the object. According to this method, it is not necessary to reconstruct the slice image with a high resolution as is required for visual display, but it is sufficient to reconstruct the image at only a sample or a set of points or pixels that are sparsely distributed within the reconstructed slice. The properties of the object are then analyzed only at these sparsely distributed pixels within the slice to make a determination for the presence or absence of explosives or contraband. This process of image reconstruction and analysis is repeated over several slices spaced through the volume of the object. In another embodiment of this invention, the set of points or pixels at which the image is reconstructed are offset spatially with respect to the set of pixels in the adjacent or neighboring slice. This invention greatly reduces the computational burden, hence simplifies the hardware and software design, speeds up the scanning process and allows for a more complete and uniform inspection of the entire volume of the object.
