Abstract: Aspects of the present invention include a feedlot bunk calling system comprising a mobile sensor arrangement comprising a ranging sensor unit, for generating a range signal indicative of a distance between the ranging sensor unit and a surface of feed within a feedlot bunk, and a positioning sensor unit, for generating a position signal indicative of a geospatial position of the mobile sensor arrangement. The system further comprises a computing module configured to generate an estimate or indication of an amount of feed in the feedlot bunk, based at least in part on the range signal and the position signal.

Abstract: The invention relates to a supporting element for attachment to bone, including means for placement of attachment means, such as screws or tape, and a surface for positioning against the bone, wherein the surface is, at least during use, provided with sponge-like biocompatible material enclosed between the bone and the surface.

Abstract: An assembly for fixating a prosthesis in body tissue such as bone of a mammal, comprising a mechanical compacting device and a mass comprising at least granules of a biocompatible material having a sponge-like structure, wherein the mechanical compacting device is designed for compacting the granules during use by insertion of the device in a hole in bone and subsequently inducing relative movement of at least a first part of the compacting device relative to a second part thereof, such that the volume of at least one space between at least part of an outer surface of the device and the adjacent inner surface of said hole is reduced.
