US 20120190386 and "survey eggs"

From published US patent application 20120190386 :



[0003] At present, when performing a boundary survey for a particular property, survey instruments are utilized to locate the corners of a property owner's lot. The surveyors often mark these corners by driving wooden stakes in the ground.

[0004] When the work is done that necessitated the boundary survey, the wooden stakes are (often) removed.

[0005] Unfortunately for the property owner, if additional work needs to be done, say a few years later, the owner must incur the cost of performing another boundary survey all over again (with potentially varying results).

SUMMARY OF THE INVENTION

[0006] The present Invention is conceived as a response to the above-described disadvantages of the conventional art. The present Invention relates to wireless, location-establishing devices (hereafter "Survey Eggs"), that are wireless Global Positioning Satellite (GPS) devices that enable surveyors to permanently locate the boundary points of property lines. Survey Eggs address problems such as having a property owner's boundary surveyed over and over, for thousands of dollars each time the owner, say, renovates their property.
