Abstract
A housing for a mine marker that houses RFID electronics. The RFID electronics is surrounded by a resiliently deformable tube that fits inside the housing, which may be an impact resistant plastic. The housing is filled with a first strengthening material and the tube may be filled with a second strengthening material. There is an impedance mismatch (a change in properties between adjacent layers so that shock waves are deflected) at the boundary between adjacent materials, (casing and first strengthening material, first strengthening material and tube, tube and second strengthening material, or casing and tube if they abut) which inhibits shock propagation.
Claims21
An RFID marker housing including:
- a first material layer surrounding at least part of RFID electronics housed within the RFID marker housing;
- and
- a second material layer surrounding the first material layer;
- wherein an interface between the first material layer and the second material layer surrounds at least part of the RFID electronics;
- and
- wherein there is a change in properties at the interface between adjacent material layers so that shock waves are deflected around the RFID electronics.
An RFID marker housing including:
- a casing;
- a core suspended within the casing within which at least part of RFID electronics is housed;
- and
- material surrounding the core and filling the casing;
- wherein there is a change in properties between adjacent layers so that shock waves are deflected at the boundary between the material and the casing.
An RFID marker housing including:
- a first material layer surrounding at least part of RFID electronics housed within the RFID marker housing;
- and
- a second material layer surrounding the first material layer;
- wherein interface between the first material layer and the second material layer surrounds at least part of the RFID electronics;
- and
- wherein there is a mechanic impedance mismatch at the interface between adjacent material layers so that shock waves are deflected around the RFID electronics.
An RFID marker comprising RFID electronics mounted in a RFID housing, the RFID housing including:
- a casing;
- a core suspended within the casing within which at least part of the RFID electronics is housed;
- and
- material surrounding the core and filling the casing;
- wherein an interface between the material and the casing surrounds at least part of the RFID electronics;
- and
- wherein there is a mechanical impedance mismatch at the interface between the material and the casing so that shock waves are deflected around the RFID electronics.
