Abstract: A method of the present invention includes exposing a structure to first electromagnetic radiation including at least one wavelength absorbed by a predetermined substance that is to be detected. Such substance can be water, a water-soluble substance, or fungi, the presence of which can be a significant problem in a structure such as a house or building. The method includes sensing second electromagnetic radiation from the structure, the second radiation based on the first radiation. The method also includes determining whether the substance is present in the structure, based on the sensed second radiation. If the substance to be detected is water and the determining step reveals a water-suspect area in the structure, the method can include testing the water-suspect area of the structure to determine whether water is present therein. If water is confirmed by the determination to be present in the structure, the method can include a step of determining the source of the water.

Abstract: A system and method for storing Responsible Organization data corresponding to toll free telephone calls provides Payphone Service Providers (PSPs) with the data for billing or auditing Per Call Compensation (PCC) charges and payment. The method includes the steps of generating a query for Resp Org data corresponding to the toll-free telephone number for a call received at a Service Switching Point (SSP), sending the generated query from the SSP to a Service Control Point (SCP), extracting Resp Org identification data from the response to the generated Resp Org query, and incorporating the Resp Org identification data into a call detail record (CDR). Preferably, the Resp Org query is included in the query for call routing data but it may be a separate query. Additionally, the Resp Org identification data is preferably included in the CDR for the received call but it may be incorporated in a separate record.

Abstract: The apparatus of this invention includes a pilot-induced oscillation (PIO) detector, a PIO compensator and a pilot input modifier. The PIO detector is coupled to receive aircraft state signal including the aircraft's pitch, roll and yaw attitudes. The PIO detector is also coupled to receive pilot control signal generated by the aircraft's pilot by manipulation of flight control instruments. Preferably, the PIO detector includes a feature calculator and a discriminator. Based on the aircraft state signal and the pilot control signal, the feature calculator generates at least one feature signal indicative of whether a PIO or non-PIO condition exists in the aircraft. The feature calculator supplies the feature signal to the discriminator, that uses the feature signal to determine whether or not a PIO condition exists.
