Abstract: In an agricultural machine vision system for the selective treatment of a field employing a boom deployed sensor and treatment device, the system utilizes at least one image sensor mounted on the boom to produce base image data. A boom angle detector detects boom height which is used to correct the base image data into remapped image data including a region of interest to produce corrected image data producing a regularized image of the region of interests for treatment, independent of boom tilt.

Abstract: The automated treatment of agricultural fields allows precise application of treatment to only areas of the field requiring treatment, allowing reduced use of agricultural products such as pesticides and the related reduction in environmental stress. Such automated treatment requires the monitoring of image information of the field to detect objects of interest such as weeds. Such monitoring of image information of the field suffers from the real world problem of shadows cast from the agricultural equipment and/or adjacent trees or structures that cast shadows across the field. Shadows are extracted from the image data by smoothing the data, and developing a shadow mask by employing an intensity histogram and identifying a local minima in the darker intensities of the histogram to identify a shadow threshold. The image areas within the shadow area detected by said mask are then corrected by multiplication with correction coefficients to extract the shadow.

Abstract: The various embodiments herein relate to imaging devices and systems that capture an image of a target object and separately capture light from the light source illuminating the target object to compensate for inconsistent lighting of that object. Some systems have scene cameras to capture the images of the target objects and a separate light capturing camera to capture the light from the light source. Other embodiments relate to a single camera capturing an image of the target object while simultaneously capturing light from the light source.

Abstract: The various embodiments disclosed herein relate to identification of one or more specific objects among several other objects. Certain exemplary implementations relate to systems, methods, and devices for identification of one or more specific plant species among several different plants, especially real-time identification of weed plant species in a real-world environment such as a crop field. Other embodiments relate to identification systems, methods, or devices in combination with action components, such as a spraying system for spraying the weed plants identified in real time.

Abstract: Computer screen contents and accompanying audio are captured by a method, embodiments of which are implemented by a specialized apparatus. Embodiments of the method include capturing an image of the computer screen contents at predetermined time intervals and determining one or more changes between a current captured image and a previous captured image. The method also includes modifying color data associated with a changed region of the current captured image and encoding the modified color data for the changed region.

Abstract: An apparatus (2) for measuring electrical conductivity in a material has a pair of electrically conducting elements (6), a first electrical conductor (9) coupled to the electrically conducting elements and coupling a first transformer core (10) and a second transformer core (12) to form a first current loop (8), and a second electrical conductor (17) of known resistance coupling the second transformer core (12) and a third transformer core (14) to form a second current loop (16).

Abstract: A hybrid structural module (10) comprising a tubular fibre composite member (20), a filled resin system (30) located within said tubular fibre composite member, and at least one elongated steel member (40) located within the filled resin system, wherein the filled resin system binds the steel member and tubular member together.

Abstract: A polymer concrete formulation comprising an amount of polymer resin; an amount of thixotrope; an amount of a light aggregate with a specific gravity less than that of the resin; and an amount of a heavy aggregate with a specific gravity larger than that of the resin.

Abstract: The present invention discloses the structure and sequence of aroQ from Bordetella pertussis, which are useful inter alia for the production of the genetically modified attenuated Bordetella strains of the present invention and for detecting and isolating variant aroQ genes and expression products. The present invention also discloses attenuated Bordetella strains of pathogenic origin, and more particularly genetically modified Bordetella strains, which have been attenuated by disruption or inactivation of the aroQ gene. The genetically modified Bordetella strain of the present invention has a reduced capacity to propagate in a mammalian host, but remains viable in the host for a period of time sufficient to induce a protective immune response against the natural pathogenic Bordetella counterpart.
