  • Publication number: 20100117667
    Abstract: A continuous-wave laser beam is chopped to form pulses synchronized to the activity of a device under testing and/or to acquisition electronics. Chopping the laser beam to reduce the duty-cycle of the beam allows the power delivered to the device during the actual probing time interval to be increased while maintaining a lower average power. Chopping the laser beam improves the signal-to-noise ratio of the continuous-wave laser voltage probing measurements. Chopping the laser beam improves the performance of the continuous-wave laser based laser voltage probing system, which may be used for measuring the internal signals of an operating integrated circuit device.

  • Patent number: 7571856
    Abstract: The prevention of counterfeiting labels for various products is addressed by introducing counterfeit-proof labels having an optically concealed, invisible universal product code. The label is printed on a high-resolution micro optic photo chromogenic material. The color bars of the code are optically split and compressed in high resolution image elements and arranged at the pre-calculated optical blind angles in relation to the optical center of the lenticule and the viewing distance of the label, and due to the optical effect of the micro lenticule, the complete color product code is not visible when viewing at a normal viewing distance. The camera of a mobile phone photographs the label at a close-up distance, with the lens of the camera regrouping the split image elements of all the color bars to reconstruct the product code that will be displayed on the screen of the mobile phone.

  • Publication number: 20090102179
    Abstract: The prevention of counterfeiting labels for various products is addressed by introducing counterfeit proof labels having an optically concealed, invisible progressive shifting security safety symbols for quick identification. The label is printed on a high-resolution micro-optic photo chromogenic material. A multiple number of images of an optically compressed security safety symbol are printed on the focal plane along the linear optical center of each micro-lenticule across the entire area or a small portion of the label. Due to the optical effect of the micro-optic, the complete security safety symbol is not clearly visible at normal viewing distance.

  • Patent number: 7444002
    Abstract: A generalized Hough transform is used to acquire and track vehicular targets for missile guidance. This is accomplished by recognizing that most vehicles have silhouettes that may be described as a “rounded rectangle”. The position and shape of such rounded rectangles is described in terms of 5 parameters (xc, yc, a, b, ?) where xc, yc are the center coordinates, a,b are the major and minor axis and ? is the orientation. The computation of a five dimensional Hough transform on an image including such a target will produce the five parameters that provide the “best fit” rounded rectangle to the target. These parameters are then passed to a missile tracker. This capability can be used to improve track gate handoff from the automatic target recognizer (ATR) to the missile tracker, changing aspect ratios of maneuvering targets, limited lock-on after launch (LOAL), aimpoint designation and fire control system to missile seeker handover.

  • Patent number: 7439730
    Abstract: A system, apparatus, and method for analyzing photon emission data to discriminate between photons emitted by transistors and photons emitted by background sources. The analysis involves spatial and/or temporal correlation of photon emissions. After correlation, the analysis may further involve obtaining a likelihood that the correlated photons were emitted by a transistor. After correlation, the analysis may also further involve assigning a weight to individual photon emissions as a function of the correlation. The weight, in some instances, reflecting a likelihood that the photons were emitted by a transistor. The analysis may further involve automatically identifying transistors in a photon emission image.

  • Patent number: 7035475
    Abstract: A non-traditional, non-uniformity compensation processor. In the illustrative embodiment, the feedforward adaptive non-uniformity compensation processor includes a multiplier which receives a video image and generates a compensated video image by multiplying the video signal by one of a noise reducing constant or one. The inventive processor further includes a shunting multiplication processor which supplies a selected one of the noise reducing constant or one to the multiplier in response to the presence of one of fixed pattern noise (FPN) and temporal noise (TN) in adjacent frames of the video image. In an illustrative embodiment, the inventive system cones the output of an FPA to generate a coned output signal. The system isolates the FPN in the coned output signal and feedforward processes the coned output signal on a pixel-by-pixel basis to generate a FPN-reduced output signal.

  • Patent number: 7032518
    Abstract: A system and method for managing the tension and maintaining registration between multiple webs in a web finishing system. The method involves transporting a first web and at least second web toward a finishing apparatus, comparing relative positions of registration marks on the webs, severing lengths of the second web in response to the relative positions, aligning each length of the second web with the first web, and then performing a finishing operation on the webs with the finishing apparatus. The system includes the finishing apparatus, devices for transporting the webs toward the finishing apparatus, devices for comparing the relative positions of the registration marks on the webs, a device for severing lengths of the second web in response to the relative positions, and a device for individually aligning each length of the second web with the first web before the webs encounter the finishing apparatus.
