Abstract:
1. A method of locating a device, wherein the device produces a field and is disposed adjacent a second side of a structure, from a first side of the structure, and where the device cannot be visualized from the first side of the structure, the method comprising: sensing the field strength produced by said device at a first location on the first side of the structure; using the field sensed at the first location to determine a first distance from the center of said device to the first location; and sensing the field strength produced by said device at a second location on the first side of the structure; and using the field sensed at said second location to determine a second distance from the center of said device to said second location; and using said sensed field strengths and said first and second distance from said first and second locations to determine a location on said first side of said structure representing a center of said field being produced by said device, and therefore a center of said device.
