    摘要： A system and methods for implementing histogram computation, for example, into the rasterization pipeline of a 3-D graphics system, are provided. With the histogram computation mechanism, statistical histogram data may be generated for input data of any kind or retrieved from any source that may be specified in a 2-D array or specified in an immediate fashion to specialized data processing hardware. Depending on the nature of the input data, the data may be filtered before passing the data to data processing hardware for further processing. The data processing hardware may then apply an additional function to the input data set before calculation of the histogram data. Then, at some point, the data processing hardware may apply a function to the data to map the derived data to a real-valued function that can then be quantized to a histogram element in the range specified from zero to the number of histogram elements minus one. The corresponding element in this histogram is then incremented according to the data received as it passes through the graphics processor. Advantageously, relatively expensive host computing resources are conserved, and developers are insulated from the tedious details required of implementing histogram computation from the ground up each time it becomes desirable to compute histogram data in connection with an application.

    摘要： The present invention is embodied in a system and method for statistically comparing a first set of digital data to at least a second set of digital data and matching the first set of digital data to appropriately corresponding portions of the second set of digital data. The first or the second set of digital data can be transformed during statistical analysis to enhance statistical analysis of the digital data.

    摘要： Apparatus and systems are provided for dual redundant avionics networks wherein a remote data concentrator (RDC) includes, but is not limited to, a line replaceable unit (LRU) input, a first processing lane coupled to the LRU input, a second processing lane coupled to the LRU input, and a processor coupled to the first processing lane and the second processing lane. The first processing lane has a first output. The second processing lane has a second output. The processor has a link coupling the first processing lane with the second processing lane and is configured to route data from at least one of the first output and the second output to an Ethernet. The link is configured to transfer data between the first processing lane and the second processing lane.

    摘要： A transducer for use in a structural health monitoring system comprises a single transducer element. The transducer comprises a transmit assembly coupled to the single transducer element. This assembly is configured to produce a multi-cycle square wave drive signal for stimulating the transducer. Additionally, a transmit/receive switch coupled to the single transducer element is provided. This assembly is configured to isolate the drive signal from the receive assembly used to sense the electrical signal generated from any received elastic waves.
