A fairing assembly includes an outer wall, a first side wall, a second side wall, and a saddle. The first side wall and the second side wall extend from opposing sides of the outer wall. Together the first side wall, the second side wall, and the outer wall form a cavity within the fairing assembly. The saddle is positioned within the cavity and extends between the first side wall and the second side wall. The saddle has a first rib adapted to connect to the first side wall and a second rib adapted to connect to the second side wall. The first rib and the second rib connect together at a central hub.

摘要:
A method of and means for demonstrating organic evolution, particularly as it involves the mechanism of natural selection. Background panels of multicolor and intricate design or pattern are used to provide simulated natural environments, and thin chips of different colors and shades -- and, in some instances, of different sizes and shapes -- are used to provide simulated animals or plants to be placed on the background panels. A population of a predetermined number of chips of a predetermined mixture of colors -- say, for instance, an equal number of from ten to twenty different colors -- is selected. The chips constituting the selected population are then spread in a single layer more or less uniformly on the surface of the background panel, and preferably in spaced relation, so that each chip is in plain view and is more or less detectible -- depending upon the color contrast existing between each chip, respectively, and the associated area of the background panel. Humans, for whom the demonstration is to be conducted, act as predators and remove from the panels a predetermined portion of the chips -- say, for instance, seventy-five percent of the total population placed on the panel. The surviving chips are then counted and noted for color, and each is reproduced in equal amount so as, for instance, to restore the original population. Reproduction is carried out by mating surviving chips and providing additional chips as simulated offspring, as are dictated by genetic demands, indicated on specially formed chips and the use of a chance device such as a specially constructed die or the like. Various aspects of natural selection may be demonstrated by this invention, including reproduction by monohybrid crosses, dihybrid crosses, and trihybrid crosses. The removal of chips as by predators, followed by reproduction for restoring the population, may be repeated any desired number of times.

A duct liner assembly includes a noise attenuation layer for absorbing noise energy that is covered by a face sheet. The face sheet includes a seam that is covered by an acoustically active splice. The acoustically active splice includes a plurality of acoustic regions that provide for communication of noise energy to the noise attenuation layer to minimize creation of acoustically dead areas.

A method and apparatus for preempting an operation in a nonvolatile writeable memory is performed using a pin. Preempting an operation is accomplished by either suspending the operation or by aborting the operation. Once an operation is suspended in the nonvolatile writeable memory, other operations can then be performed. Subsequently the suspended operation may be resumed.

A method and apparatus suspend a program operation in a nonvolatile writeable memory. The nonvolatile writeable memory includes a memory array, a command register, and memory array control circuitry. The command register decodes a program suspend command and provides a suspend signal as an output. The memory array control circuitry is coupled to receive the suspend signal from the command register. The memory array control circuitry performs a program operation in which data is written to the memory array. The memory array control circuitry suspends the program operation upon receiving the suspend signal.
