A light diffusing composition that optimizes image clarity from a SSID comprising a translucent matrix further comprising a plurality of hollow micro-particles. A broad band light source is split into two beams. The diffusion unit includes a first diffusion sheet and a second diffusion sheet. A thin plastic tongue projects from the carrier and bears a touch memory device. The flow field generator processes the sequence of images and generates a substantially distortionless flow field representing the motion within a scene. Thus, the generic APIs allow the control application to be network processor independent and to manage the congestion control and avoidance behavior of the heterogeneous network processors in the network processor specific manner.
