Abstract: Systems and methods for employing opportunistic data transfer to create a dynamically mobile data communication system. Implementation of the present invention takes place in association with a computer environment with many possible types of computer system configurations such as personal computers, hand-held devices, multi-processor systems, microprocessor-based or programmable consumer electronics, networked PCs, minicomputers, mainframe computers, and the like. Data is automatically compared and replicated between communication nodes when the nodes are within transmission range in order to move the data by creating redundant copies ofthe data. Communication between communication nodes is enabled by one or more network interfaces that include an opportunistic data transfer protocol (“ODTP”) component.

Abstract: A seed planting system providing optimal seed spacing in an agricultural field. The seed planting system includes a mobile seed planter having one or more planting shoes, or members being adapted for towing by a farm vehicle or being self-propelled. Sensors, disposed proximate to respective planting shoes, detect seed planting events and send corresponding signals to a computer. Contemporaneously, a geospatial locator acquires, and transmits to the computer, the geospatial location of each planted seed. The computer correlates the geospatial location data with the seed deposition data and generates a seed distribution profile indicating the location of each seed planted in a zone of interest to enable the control of speed spacing.
