  • Patent number: 6906628
    Abstract: The invention concerns a system for detecting multiple tags in a detection zone. The system includes an electronic tag detection system having first and second field generators, each having a respective antenna for generating an electromagnetic field in a detection zone defined between the antennas. Additionally, at least one of the field generators can be responsive to a presence of at least two electronically detectable tags in the detection zone, for varying an intensity of at least one of the electromagnetic fields.
    Type: Grant

  • Patent number: 5353796
    Abstract: A non-invasive apparatus and method for measuring fat thickness or content and muscle depth or area parameters grading meat and animals are disclosed. The device includes an ultrasonic transducer and analyzer device which provides A scan information in digitized form. A separate controller moves the ultrasonic transducer along a predetermined path adjacent an animal or carcass while A scans are obtained at predetermined locations along the path. The A scans are digitized and analyzed to determine the tissue interface boundaries. Equations are implemented to determine the area of the longissimus muscle and fat tissue thicknesses and a lean content rating for the animal may be determined therefrom. Modeling techniques are also used to estimate certain portions of the area of the longissimus muscle of the animal or carcass based upon data gathered during the ultrasound scanning of the carcass.
