Abstract: A link controller for use in a node of a network includes a digital controller (102) that employs a knowledge-based control program (103). The device and method provide flexible master node designation, automatic installation, configuration and reconfiguration, and recognition and correction of network communication problems resulting from interference and other adverse conditions. The knowledge-based control program (103) employs an inference engine and a set of rules to dynamically optimize network configuration. Multipath is managed by locking on to reflected signals when a direct signal is unavailable. Operation is transparent to network users.

Abstract: A dielectric/conductive waveguide (20) includes a dielectric housing (22) having a longitudinal axis (14) and a central channel (29). A conductive layer (24,25) is affixed to the inner surface (21 ) and/or the outer surface (23) of the housing (22) to confine electromagnetic radiation (17) within the waveguide (20). Ribs (50,64) protruding into the channel (29) may be used to further confine the radiation (17). Sections of waveguide (20) may be combined using connectors (30). A local area network (90) can be formed using a plurality of sections of waveguide (20), computers (94), and bi-directional couplers (92). Air gaps (98) may break up the waveguide (20) at various places.

Abstract: A food product dispensing apparatus and method which prevents the product from being damaged when the product is dispensed. A food product cooking apparatus and method which preserves the cooking oil such that the oil needs only be changed at two to four week intervals. The present apparatus and method relates to vending-frying machines for dispensing and cooking food products. The instant invention extends the intervals between when such vending machines need be serviced.
