Abstract: A method and system for determining the effect of precipitation on flow within a sewer network includes identifying a modeled response of the sewer to a precipitation event. Once the modeled response is identified, scaled responses to future precipitation events may be predicted, in real time, by measuring intervals of the precipitation event and calculating the scaled response as a function of the modeled response and the precipitation quantity measured during the precipitation event.

Abstract: An antenna assembly is formed from at least one antenna and associated conductive connecting element (wires, conductive gel or liquid, etc.) mounted within a deformable membrane that allows the antenna assembly to be installed or fixed within a narrow gap or crevice, wherein the gap or crevice may be subject to harsh environmental conditions. The gap or crevice is preferably a gap or crevice in a closure. The antenna assembly typically has a low profile, and is installed either flush with or within a traffic surface or within ¼″ above the surface. The deformable membrane will yield under force, but return to its original shape once the force is removed. The deformable membrane and antenna assembly will deform to conform to the shape of a gap or crevice into which the antenna assembly is installed.

Abstract: A method and system for monitoring and analyzing flow in a sewer system includes the steps of using a monitoring assembly to collect data representative of actual flow volume of a fluid substance in a first location such as a sewer pipe, storing the actual flow volume data in a memory, maintaining previously stored data in the memory, determining a predicted flow volume and comparing the actual flow volume with the predicted flow volume to yield a difference value. The predicted flow volume is dependent on the data selected from the previously stored data and a day and time that corresponds to both the actual flow volume data and the data selected from the previously stored data. The predicted flow volume may also be dependent upon additional data corresponding to a rain event.

Abstract: A method and system for analyzing flow of a substance in a sewer system determines a first flow velocity at a first location and a second flow velocity at a second location. Using a processor, the travel time between the two locations is determined using only the flow velocities and a constant. The travel time may then be used to provide a substantially accurate determination of net flow between the two locations.

Abstract: A method and system for determining the effect of precipitation on flow within a sewer network includes identifying a modeled response of the sewer to a precipitation event. Once the modeled response is identified, scaled responses to future precipitation events may be predicted, in real time, by measuring intervals of the precipitation event and calculating the scaled response as a function of the modeled response and the precipitation quantity measured during the precipitation event.

Abstract: A dipole antenna is constructed of flexible conductive elements. These elements are encased in a flexible protective covering or attached to a semi-rigid substrate. This covering protects the antenna during handling, transport, and installation. The conductive elements and the protective covering may be further encased or embedded in an external protective covering. The final external protective covering serves as an adhesive to permanently attach the antenna to a mounting surface. When installed on the mounting surface, the antenna has a low profile with respect to the mounting surface.

Abstract: A checking apparatus for flat type display panels includes a multiple number of cameras used for picking up images of a check pattern that is generated by a check pattern generator in accordance with a check item and displayed on a liquid crystal panel and a high-speed image processor for processing the obtained image signal from the taken image so as to detect defects in accordance with the check item. Further, the apparatus is constructed such that, as to some check items, the area of the display panel is divided into a multiple number of sections and a multiple number of check patterns are displayed at the same time in respective sections to thereby perform checking on multiple check items simultaneously. Alternatively, the apparatus is constructed such that, checking as to some check items is performed by processing image signals obtained in only a previously designated part of the liquid crystal panel.
