Abstract: A subsea electronic device includes a housing, a chassis within the housing to which one or more electronic cards are mounted and heat transfer sections in thermal contact with the electronic cards. The heat transfer sections are in interference fit with an inner surface of the housing thereby to transfer, in use, heat from the electronic cards through the heat transfer sections to the housing. There is also a subsea electronic device housing and a method of assembling a subsea electronic device.

Abstract: An apparatus for use subsea includes a container having at least one aperture; a lid securable to the container to cover the at least one aperture, suitable to isolate the inside of the container from the outside of the container when fluid pressure outside the container is at least 5000 kPa. The lid has one or more electrical connections providing electrical communication from a first side of the lid to a second side of the lid. The apparatus further includes one or more wires for providing electrical communication between one or more electrical components in the container and the one or more electrical connections in the lid.

Abstract: A subsea electronic device (1) including a housing (2), a chassis (3) within the housing (2) to which one or more electronic cards (4) are mounted and heat transfer sections (5) in thermal contact with the electronic cards (4). The heat transfer sections (5) is in interference fit with an inner surface of the housing (2) thereby to transfer, in use, heat from the electronic cards (4) through the heat transfer sections (5) to the housing (2). There is also a subsea electronic device housing (2) and a method of assembling a subsea electronic device (1).

Abstract: An apparatus (10) for use subsea including a container having an aperture, a lid (12) securable to the container to cover the aperture, a printed circuit board, at least one fibre-optic (18) connecting the printed circuit board to the lid (12) and a substantially rigid support (14) locatable in the container. The lid (12) is suitable to isolate the inside of the container from the outside of the container when fluid pressure outside the container is at least 1000 kPa. The support (14) has at least one upstanding member around which one or more fibre-optics (18) are locatable such that the smallest radius of a bend in the fibre-optic(s) (18) is greater than the minimum bend radius thereof.

Abstract: Remotely sensed spectral image data are used to develop a Vegetation Index file which represents spatial variations of actual crop vigor throughout an area that is under cultivation. The latter information is processed to place it in a format that can be used by personnel to correlate and calibrate it with actually observed crop conditions existing at control points within the area. Based on the results, personnel formulate a prescription request, which is forwarded to a central processing site, where the prescription is prepared. The latter is returned to a mobile application means that directly applies inputs to the field at a spatially variable rate.

Abstract: Remotely sensed spectral image data are used to develop a Vegetation Index file which represents spatial variations of actual crop vigor throughout a field that is under cultivation. The latter information is processed to place it in a format that can be used by farm personnel to correlate and calibrate it with actually observed crop conditions existing at control points within the field. Based on the results, farm personnel formulate a prescription request, which is forwarded via email or FTP to a central processing site, where the prescription is prepared. The latter is returned via email or FTP to on-side farm personnel, who can load it into a controller on a spray rig that directly applies inputs to the field at a spatially variable rate.
