Abstract: Generally, in a non-destructive test application, a compressed representation of an acoustic echo signal acquired by a non-destructive test (NDT) probe assembly can be received, such as via a network. The compressed representation can include data indicative of changes in phase values of the acoustic echo signal. Using the compressed representation, a time-domain representation of an instantaneous phase signal can be constructed from the compressed representation. The constructed instantaneous phase signal can be used in constructing at least one of an uncompressed acoustic echo signal representation or an image. As an illustration, amplitude values of sampled acoustic echo signals can be suppressed in the compressed representation, reducing data volume associated with transmitting a representation of the acquired acoustic echo signal.

Abstract: There is described a setting tool for setting anchors into holes formed in masonry comprising; a bit including a cutting portion for penetrating the masonry, a stem for gripping by a drill and an enlarged diameter collar portion between the cutting portion and the stem, and a hollow sleeve portion open at one end adapted to fit over the cutting portion of the bit so that the cutting portion is freely rotatable in the sleeve, the open end of the sleeve being adapted to abut against the collar portion for transmitting an impacting vibration from the drill to the sleeve portion; and an anchor setting portion extending axially from the end of the sleeve opposite to the open end thereof, the setting portion being adapted to engage temporarily an anchor to be set in the hole.
