A source node for addressing target nodes in a communication system, the source node configured to be part of an Ethernet domain and the target nodes configured to be part of a Multiple Protocol Label Switching domain that is connected to the Ethernet domain via an interworking node. A shared speech processing facility is used to support speech recognition for a wide variety of devices with limited capabilities including business computer systems, personal data assistants, etc. The stacked polysilicon layer inhibits the diffusion of boron in the dielectric layer and the penetration of boron into the dielectric layer and the semiconductor substrate. Since the blending ratio of colorants for reproducing the desired target color may be calculated based on the input color specification value data and stored color data, such CCM calculation may be performed without the necessity of a spectrophotometer. Memory assemblies include memory chips having chip bond pads on both sides of the memory chip shorted to each other by a single lead of a leadframe. Particularly, the method and apparatus involve collecting air samples containing aerosolized contaminate particles from a foodstuff and analyzing the sample for presence of a contaminate.
