Abstract: Devices for reforming frying oil in a cooking vessel for the purpose of prolonging the freshness and usable life of the frying oil. The devices include beads that come into contact with the frying oil and reform the frying oil at ordinary temperatures, where each bead has a coating that is formed on the surface of a substrate and acts as a reforming catalyst. One of the devices includes a mounting adapter having flanges to mount on a pair of heating pipes or heating surfaces of a cooking vessel, a bead container for containing the beads; and hook brackets connected to the bead container and configured to couple to the mounting adapter so that the bead container is suspend to the mounting adapter during operation. The bead container has perforations on its walls to make the beads contact with the frying oil.

Abstract: Systems, methods and recordable media for prognosticating a structural condition. A method for prognosticating a structural condition by use of a network having a plurality of diagnostic network patches (DNP), each of the patches being able to operate as at least one of a transmitter patch and a sensor patch, includes the steps of: (a) causing at least one of the patches to emit a transmitter signal and a portion of the other patches to receive a set of sensor signals at a point in time; (b) repeating the step (a) to receive multiple sets of sensor signals at multiple points in time, respectively; and (c) prognosticating, based on the multiple sets of signals, a structural condition of a host structure of the network at a target point in time.

Abstract: Systems, methods and recordable media for identifying damage in a structure. A method includes the steps of: obtaining a plurality of damage index values for a network coupled to the structure, wherein each of the damage index values is a quantity to be affected by damage in the structure; generating a distribution of damage index value over a surface using the obtained damage index values; and identifying the damage by analyzing the distribution.

Abstract: Systems, methods and recordable media for generating tomographic images to monitor structural health conditions. A method includes the steps of obtaining a plurality of damage index values for a network that is coupled to a host structure and has a plurality of diagnostic network patches (DNP), generating a distribution of damage index value over a surface using the obtained damage index values, and formatting the distribution as at least one tomographic image. Each of the patches is able to operate as at least one of a transmitter patch and a sensor patch. The damage index values is a quantity to be affected by damage in the host structure or associated with signals generated by the patches in a response to an impact on the host structure.
