    摘要: Method and apparatus for dynamic configuration of function block logic of an integrated circuit is described. The integrated circuit includes a reconfiguration port coupled to a controller. The controller is coupled to an array of memory cell. A portion of the array of memory cells is coupled for read/write communication with the controller, and another portion of the array of memory cells is not coupled for read/write communication with the controller. The portion of the array of memory cells is configurable at an operational frequency of the integrated circuit for dynamic reconfiguration of the function block logic of the integrated circuit.

    摘要: An apparatus for receiving signals from a photodetector in a photodetector array. The apparatus has a number of comparators (e.g. 5) connected to the photodetector. each photodetector in the array has a similar circuit connected. Each comparator compares the output of the photodetector with an adjustable threshold level. Each threshold level is controlled by a threshold controller. Each threshold level corresponds with a light intensity value. Outputs of the comparators are each connected to a shift register. Each shift register is triggered to sample the output of its associated comparator at a certain speed (e.g. 800 Mhz). In operation, the shift registers each store a bit sequence representative of the comparator output. The data acquired is used to adjust the threshold levels applied to the comparators. In this way, adjustable intensity resolution is provided at desired ranges of intensity. The present invention includes a method for combining data from multiple laser pulses and fitting the data to a best fit statistical distribution so that an intensity value is obtained for each voxel in a 3-D laser radar image. Also, the present invention includes embodiments where different photodetectors in the array have different set threshold levels.

    摘要: Isolation and characterization of a novel plant fatty acid desaturase cDNA that encodes a .DELTA..sup.9 14:0-ACP desaturase. Expression of the .DELTA..sup.9 14:0-ACP desaturase is a critical factor for pest resistance in plants of the genus Pelargonium and other plants generally; the desaturase gene is also useful in other contexts and for other purposes such as increasing the percentage of unsaturated fatty acids in oil-producing crops such as soybeans, rapeseed, maize, sunflower, safflower, cotton, cuphea, peanut, coconut and oil-palm, as well as increasing the percentage of unsaturated fatty acids in other plants generally.
