  • Patent number: 11523571
    Abstract: Embodiments for crop-specific automated irrigation of an environmental medium and management of nutrients therein. In one aspect, operation of an irrigation apparatus can be regulated according to specific water demand of a crop. The water demand can be assessed by evaluating water content conditions of the environmental medium comprising the crop, medium characteristics, and/or nutrient delivery and transport characteristics at the medium. Regulation of operation of the irrigation apparatus can comprise control of one or more of water supply to the apparatus, positioning and/or movement of the irrigation apparatus, or configuration of sensing devices for collection of information suitable for such regulation.

  • Patent number: 10477784
    Abstract: A land irrigation system to irrigate farmland. The system includes a water delivery pipe assembly having a plurality of drive motors mounted thereto. The water delivery pipe assembly is configured for one or the other or both of linear-move irrigator travel and center pivot irrigator travel. The water delivery pipe assembly is further configured to stagger the operation of select ones of the drive motors wherein when one or more of the selected drive motors are in operation one or more of the selected drive motors are not in operation. Staggering the operation of select ones of the drive motors can serve to reduce the carbon footprint as well as size footprint of the power supply that powers the drive motors whether that supply be a diesel generator or a water motor driven generator or an inverted battery power supply or a fuel cell or other.

    Abstract: Apps are secured or security-wrapped either before they are downloaded onto a device, such as a smart phone or tablet device, or after they are downloaded but before they are allowed to access the device operating system and cause any potential damage to the device. The app is secured before it is allowed to access the operating system of the device, thereby preventing the app from malicious behavior. App object code is substituted with security program object code, thereby creating a security-wrapped app. The app is provisioned with a geo-fencing policy which prevents execution of an app outside a pre-defined geographical area. If the device is within the defined area, the app is allowed to execute. The geographical area, such as a building or company campus, is defined using longitude and latitude coordinates and a location accuracy value. Device location is obtained using location/GPS services on the device.

  • Publication number: 20110220743
    Abstract: A swing arm support system for automated irrigation systems has a support hub and a means to attach and operate two wheels to opposite sides of the support hub. The support hub provides greater ground flotation to prevent the forming of ruts in a field and traction to prevent an automated swing arm from becoming stuck. The swing arm support system provides for the use of common automated irrigation components so that fabrication, repair and operation are most efficient. The support hub in pivotally attached to an existing swing arm support tower. The support hub is carried by two pneumatic tires in one embodiment, four tires in another embodiment, six tires in another embodiment, and movable tracks in another embodiment.

  • Patent number: 7883035
    Abstract: A mobile drip irrigation system that includes a supply pipe connected at one end to a liquid source and extending therefrom. At least one tower supports the supply pipe above the ground, and includes a driver for moving the tower and supply pipe in a desired direction. A plurality of ports are positioned along the supply pipe. The system includes a plurality of vertically oriented drop line assemblies. Each drop line assembly has an upper end connected to one of the plurality of ports, and a lower end spaced above the ground. A horizontal liquid distribution system is fluidly connected to the plurality of drop line assemblies to allow a horizontally uniformly spaced drip of the liquid at a desired distance from the ground.

  • Publication number: 20100176225
    Abstract: A self-propelled irrigation system has an elongated pipeline supported above a field by a plurality of drive towers. The drive towers each have a base beam assembly, a tower structure extending above the base beam assembly for supporting the elongated pipeline, and a plurality of drive wheel assemblies for moving the base beam assembly over a field. The drive assemblies include first and second drive assemblies mounted to respective ends of the base beam assembly. At least one of the drive towers also has a third drive assembly mounted to the base beam assembly between the first and second drive assemblies. The base beam assembly supporting the third drive assembly is articulated between its first and second ends and pivotally connected to the lower ends of the tower structure to allow the third drive assembly to move vertically relative to the first and second drive assemblies when traversing uneven terrain.

  • Patent number: 7686234
    Abstract: An irrigation assembly has a main pipeline supported at intervals by mobile towers, a plurality of drop tube assemblies at spaced intervals along the pipeline and a collector positioned to receive water from the drop tube assembly. A plurality of targets are positioned on the ground in the paths of motion defined by the movement of the collectors. The targets may be dishes. Each dish preferably has a perforated drain that penetrates beneath the surface of the ground. Interaction between the collector and the target causes the water stored within the collector to be released into the target. The irrigation assembly may provide for underground irrigation without a collector where a dish or trough receives water from the drop tube assembly and underground drains allow for water to be dispersed below the ground.

  • Patent number: 7546963
    Abstract: Connecting apparatus for use with centre pivot irrigation equipment that includes a boom supported on ground wheels and made up of one or more pipes arranged to rotate about a water supply pipe to which the boom is connected. The apparatus is provided with a U-shaped flexible pipe assembly for connecting the boom to the water supply pipe so as to enable the boom to move radially towards and away from the water supply pipe as it rotates while remaining connected thereto. This radial movement causes the distance between the ground wheels and the water supply pipe to vary and reduces the damage caused to a crop and the land in the path of the wheels. The apparatus includes a structure that is rigidly connected to the inner end of the boom. The structure may include rails that slide over a seat mounted on the water supply pipe.
