摘要:
A scanning method and apparatus for providing a geometrically corrected large angle whiskbroom scan of a portion of the earth's surface using a linear array of radiation-sensitive detectors mounted in a low earth orbiting satellite contemplate: scanning a portion of the earth's surface with the array to define an irregularly-shaped swath on the surface which represents a field of view of the array, defining a regularly-shaped ground area of interest within the field of view of the array, dividing the area of interest into a number of pixel lines fewer in number than the number of detectors in the array and extending generally perpendicularly to the array, subdividing each pixel line into a plurality of pixels, each of which encompasses at least a portion of the field of view, selectively combining outputs from the detectors to provide a data signal representative of each pixel, and reconstructing a representation of the ground area of interest from the data signal.
摘要:
A musical instrument comprising a keyboard and related controls (i.e., foot pedals, stops or equivalent controls), which through electronic circuitry remotely direct the mechanical manipulation of taut strings of guitar gauge, enabling the keyboard musician to create the many sounds characteristic of the electric guitar. Apart from the mechanical apparatus engaged with the strings, this invention relates, to a large extent, to the employment and design of the controlling electronic circuitry.
