One embodiment relates to a radar system. The long fibers include groups continuously extending between each pair of the adjacent sealing lines to form bridge-like portions and groups severed in two sections between each pair of the adjacent sealing lines so as to fluff upward on the base sheet. A chip is provided having a ground pin connected to the system ground terminal and an input pin for receiving the fault detection signal. One or more problem areas are defined within the physical network topology, where the one or more problem areas include locations where signal quality is degraded. The hit and miss match lines may be electrically isolated from one another, such that when one or more of the respective miss signals are asserted, current from the hit match line does not discharge through the miss match line. More particularly but not exclusively, it relates to compositions containing thaumatin having particular organoleptic properties, and to processes for their manufacture.
