Abstract: A system and method for generating fluid flow parameter data for use in aerodynamic heating analysis. Computational fluid dynamics data is generated for a number of points in an area on a surface to be analyzed. Sub-areas corresponding to areas of the surface for which an aerodynamic heating analysis is to be performed are identified. A computer system automatically determines a sub-set of the number of points corresponding to each of the number of sub-areas and determines a value for each of the number of sub-areas using the data for the sub-set of points corresponding to each of the number of sub-areas. The value is determined as an average of the data for the sub-set of points corresponding to each of the number of sub-areas. The resulting parameter values then may be used to perform an aerodynamic heating analysis.

Abstract: In one embodiment there is provided an aquatic toy configured for movement under water. The aquatic toy employs sensors to automatically turn on when placed in water and further employs a timing circuit to automatically turn the toy off after a predetermined amount of time. The aquatic toy further includes a shock sensor to monitor movement of the toy when in water and after the timer expires. Movement such as tapping on the tank, splashing the water, or physical movement of the toy will turn on the toy and re-activate the timer. However, the sensors can further detect when the toy is dry to ensure the shock sensor is only active when the sensor is wet.
