BRIEF DESCRIPTION OF DRAWINGS

[0054] Preferred features, embodiments and variations of the invention may be discerned from the following Detailed Description which provides sufficient information for those skilled in the art to perform the invention. The Detailed Description is not to be regarded as limiting the scope of the preceding Summary of the Invention in any way. The Detailed Description will make reference to a number of drawings as follows:

[0055] FIG. 1A illustrates an exploded view of a backend assembly for a core drilling tool;

[0056] FIG. 1B illustrates an assembled view of a backend assembly for a core drilling tool; and

[0057] FIG. 2 illustrates an exploded view of a spindle bushing according to an embodiment of the invention.

DESCRIPTION OF EMBODIMENTS

[0058] In FIG. 1A and 1B, an exploded view (1A) and an assembled view (1B) of a commercially available backend assembly for a core drilling tool as used in the art is illustrated. Backend assembly 100 comprises a spearhead assembly (12), a latching mechanism (14), a landing shoulder (16), a spindle assembly (18) and inner tube cap assembly (20). Spindle assembly (18) comprises a measurement device in the form of a spindle bushing (10).

[0059] In FIG. 2, an exploded view of a measurement device 10 in the form of a spindle bushing according to an embodiment of the invention is illustrated. Measurement device 10 comprises a housing portion (30), a lid portion (32), data acquisition portions (36) and a power source (38). Lid portion (32) is screw threadably engaged with housing portion (30) and comprises apertures (40) for receiving external antennae (42) associated with a communication portion of the data acquisition portions (36). Data acquisition portions (36) and power source (38) are positioned in receiving portions (44) located in the body of the housing portion (30).

[0060] In the present specification and claims (if any), the word ‘comprising’ and its derivatives including ‘comprises’ and ‘comprise’ include each of the stated integers but does not exclude the inclusion of one or more further integers.

[0061] Reference throughout this specification to ‘one embodiment’ or ‘an embodiment’ means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrases ‘in one embodiment’ or ‘in an embodiment’ in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more combinations.

[0062] In compliance with the statute, the invention has been described in language more or less specific to structural or methodical features. It is to be understood that the invention is not limited to specific features shown or described since the means herein described comprises preferred forms of putting the invention into effect. The invention is, therefore, claimed in any of its forms or modifications within the proper scope of the appended claims (if any) appropriately interpreted by those skilled in the art.
