摘要： Coherent light is projected through a scattering medium. The light emerging from the medium is a superposition of a multitude of scattered wavelets, each of which represents a specific scattering path. These wavelets are projected onto a diffuse reflecting surface (the viewing plane of a two-dimensional photodetector array) where they interfere with each other, giving rise to a speckle pattern. By introducing a focused ultrasound pulse into the medium, the position of the scatterers are changed at a known location (probe region) in the medium, and this causes a change in the speckle pattern. By comparing speckle images before and after the scatterers are moved, the light absorption properties of the probe region can be measured even though multiple scattering interferes with direct imaging of the region.

摘要： Method and apparatus is disclosed for automatically processing visual images electronically so as to permit intelligent machine analysis of the image content. A special distributed logic system architecture facilitates rapid real time image analysis and the production of reaction control signals in a high speed production line environment, for example. Dedicated decision logic is employed to determine in but a single micro-instruction cycle whether a detected corner point of the image should be linked to another already linked chain of such corner points so as to define part of a closed edge contour of the image under examination. This ability to so rapidly classify encoded corner points as either belonging or not belonging to a given set of such corner points which describe a closed edge contour is quite useful in achieving rapid real time image analysis capability. Special dedicated data address indexing circuitry is also employed for most expeditiously retrieving successive address linked data words from a data memory in successive single micro-instruction cycles as required to take full advantage of the high speed dedicated corner point matching circuitry. The dedicated data memory indexing circuitry is provided in addition to the usual program instruction indexing circuitry employed in connection with the instruction register of the associated data processing system.

摘要： Embodiments of the present invention beneficially provide an ultrasound communication system and methods of ultrasound communication for diagnostics and prognostics of structures. For example, ultrasound transmitters are connected to a metal or composite structure and modulated to produce Lamb waves that travel to an ultrasound receiver. The ultrasound transmitters can use frequency-hopped signals to digitally encode transducer information among different transmitters. The transmitters can be operated asynchronously. The receiver can use a channel equalizer to reduce the effects of signal multipath and a decoder to decode the transducer information from the ultrasound transmitters.

摘要： A method for determining the average gray value of a plurality of regions within a digitized electronic video image and for determining the color of the region from the average gray value. Initial image segmentation is accomplished by thresholding a multibit digital value into a one bit black and white representation of a picture element of the region. The gray values of the picture elements within either a black or a white region can then be analyzed to determine the average gray value by constructing a histogram of each region and eliminating from the histogram the picture elements not associated with the actual color or shading of the region of interest. The remaining picture elements are averaged to obtain the average gray value for the region.

摘要： A weighing scale with an electrical output includes a mechanical-to-electrical signal transducer which has a zero weight signal value which may vary in response to ambient conditions. The scale includes a fast acting switch operable to provide a switching function in response to the initiation of the placement of a weight upon the scale and a weight registering circuit operable in response to the switching function to register and store a zero weight signal before the signal transducer begins sensing the weight. The weight registering circuit is then operable to register the difference between the zero weight signal value and the ultimate signal from the transducer as the true weight.
