Abstract: The invention provides DNA compositions that relate to transgenic insect resistant maize plants. Also provided are assays for detecting the presence of the maize DAS-59122-7 event based on the DNA sequence of the recombinant construct inserted into the maize genome and the DNA sequences flanking the insertion site. Kits and conditions useful in conducting the assays are provided.

Abstract: A semiconductor wafer imaging system for imaging a semiconductor wafer includes shroud panels defining a black box, a camera positioned in the black box for imaging the semiconductor wafer, and an illumination panel for directing diffuse light to the semiconductor wafer. A portion of the diffuse light is reflected off the semiconductor wafer and the camera images the semiconductor wafer by detecting the reflected diffuse light.

Abstract: A picture frame and hanger bar together provide a picture hanging system that requires a single hanger bar in addition to the picture frame itself. The picture frame hanger has a wall mounting surface that during use is affixed to the wall or other vertical surface and the picture frame is provided with a downwardly facing skid member that is recessed within a pocket in the rear of the picture frame. The hanger bar is provided with an upwardly facing ramp surface that is canted downwardly proceeding toward the wall so that when the skid on the picture frame engages the canted surface, the picture frame will slide rearwardly toward the wall on the canted surface so as to press the picture frame against the wall by the force of gravity. The hanger bar preferably applies pressure to a backer board positioned behind the picture or other graphic article for holding it in a flat condition.

Abstract: A laser velocimeter signal processor for measuring the signal frequency within a signal burst. The input signal is converted to digital by an ADC 16 and then shifted into shift registers 30 and 31. An automatic gain circuit 15 controls the gain of the input signal. A signal integration circuit 32 determines when a signal burst has been captured by the shift registers and and then transfers the contents of the registers to data latches 33 and 34. The data in data latches 33 and 34 is processed by digital bandpass filters 57-63, square law detectors 64-70, burst counters 71-77 and signal processor 78 to determine the frequency of the signal within the captured signal burst.

Abstract: A laser velocimeter covariance processor which calculates the auto covariance and cross covariance functions for a turbulent flow field based on Poisson sampled measurements in time from a laser velocimeter. The device will process a block of data that is up to 4096 data points in length and return a 512 point covariance function with 48-bit resolution along with a 512 point histogram of the interarrival times which is used to normalize the covariance function. The device is designed to interface and be controlled by a minicomputer from which the data is received and the results returned. A typical 4096 point computation takes approximately 1.5 seconds to receive the data, compute the covariance function, and return the results to the computer.
