Abstract
A passive electronic marker comprising a single tuned LC circuit, having an inductance and one capacitance element, that respond substantially uniformly to a marker locating instrument irrespective of the orientation the marker was installed in. The inductance is split among more than one electrically contiguous coils; each of the coils is oriented in different axes along the three dimensional space to achieve the substantially uniform response to a marker locating instrument. The tuned circuit is enclosed in a protective housing that may or may not help in the orientation of the marker during burying. The passive marker is of a type that is buried relative to portions of an object for use in locating such objects when necessary.
Claims3
A passive electronic marker for use in locating buried objects, comprising:
- a) a single capacitance-inductance tuned circuit.
- b) said inductance comprising two or more electrically contiguous coils oriented in three dimensional space such that the axes of said coils are at different positions or angles to each other.
- c) said capacitance, which together with the said inductance, tune the said circuit to one desired frequency.
- d) a housing to enclose and protect the said tuned circuit.
- e) said marker being buried without care of the orientation and being able to detect the said marker with a locating instrument more uniformly in any orientation.
