Abstract: Disclosed herein are: systems capable of searching, receiving and conglomerating the data from real estate databases of varying formats, and translating that received into a common format; execution of pre-defined translation rules referencing data tags used within the system or the originating databases; rules constructed in a simple, hierarchical or a class-based structure whereby one rule depends upon the output of another rule for its input; data sources prioritized or merged where the same property-related information is presented in more than one source; map definitions containing rule sets crafted for a particular use, such as for a particular consumer or user; such systems used in the course of real estate appraisals, in property search reports, extending across databases of differing formats. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.

Abstract: A magnetic detection device for detecting the position of a movable member which is associated with a piece of magnetic material, the movable member being displaceable in a non-magnetic tube. A detection unit fixed outside the tube and including a permanent magnet with pole pieces directed towards the tube and extended portions extending away from the tube. The extended portions may be either in a plane parallel to or perpendicular to the axis of the tube. A dry reed relay is fixed relative to the pole piece with its ends facing the extended portions remote from the magnet. The extended portions may extend from opposite sides of the tube in which case the extended portions are perpendicular to the axis of the tube and the axis of the reed relay has a normal parallel to the axis of the tube. Alternatively, the reed relay is disposed parallel to the axis of the tube in which case the pole pieces are disposed on the same side of the tube.
