A network-based sensing system for monitoring an object is disclosed. The system includes a sensor, attached to the object, that collects object information, a first wireless access point that operates in a first private network covering a first private region, and at least one cellular base station that operates in a public network outside of the first private region. The sensor includes functionality to detect a location of the sensor in a location detection period and to determine a type of network coverage of the sensor. The sensor establishes connection with the first wireless access point via a first private network for transmitting the object information, when the sensor is covered by the first private network, and with the at least one cellular base station via a public cellular network for transmitting the object information, when the sensor is covered by only the public cellular network.

System and techniques for an image filter based on row identification are described herein. A crop row center represented in an image of a crop row can be calculated. A filter corresponding to a set of expected crop characteristics of the crop row can be obtained. Elements in the image can then be categorized based on applying the filter to the image when the filter anchored on the crop row.

A system for generating a non-visual notification of a machine condition includes a machine condition sensor configured to sense a machine condition. A notification generation controller is in communication with the machine condition sensor. The notification generation controller generates a notification according to the sensed machine condition. In a feedback configuration the notification generation controller compares an integral of a rate of change of the sensed machine condition with a threshold to trigger the generation of a notification. In a guidance configuration the notification generation controller uses the deviation of the machine condition from a guidance direction determined with a steering algorithm to control the generation of a notification. A non-visual notification generator is in communication with the notification generation controller and generates a non-visual notification based on the notification.

System and techniques for optical flow sensing applications in agricultural vehicles are described herein. A plurality of digital images of an agricultural environment can be obtained from a sensor affixed to agricultural equipment. The plurality of digital images can include a first image and a second image, the second image being captured subsequent to the first image. A transformation of a landmark between the first image and the second image can be identified. A degree of motion for the agricultural equipment relative to an environmental target can be calculated based on the transformation of the landmark.

In a system and method for a web based system using events and pushed web content to interact with remote users for notifications and data collections operations may be performed including receiving, from a computing device, event data concerning a job being performed by a piece of agricultural equipment wherein the event data includes an identifier associated with the agricultural equipment. A database may be queried to determine a subscriber associated with the identifier. The event data may be transmitted to a network address associated with the subscriber. A response message may be received from the subscriber and forwarded to the computing device. The computing device may connect with the subscriber via a web application address included in the response message.

This document discusses, among other things, apparatus and methods for a multi-section applicator having variable-rate sections. In an example, an apparatus can include at least one distribution manifold, a user interface, and an applicator controller. The at least one distribution manifold distributes a substance and can include an inlet port configured to receive the substance, a plurality of outlet ports, one or more sensors located at an outlet port, a controllable valve that supplies the substance to the inlet port. The applicator controller measures a value of the distribution parameter using the sensor signal produced by the at least one sensor of an outlet port, detects when the measured value differs from a specified target value by more than a specified error threshold value, and presents an indication, using the user interface, that the measured value differs from the target value according to the detection.

A means of accurately determining the position of a selected location such as at the end of a center-pivot irrigation system by using two Global Positioning System (GPS) receivers. The first GPS receiver is located at a fixed, known position such as at the center of the pivoting irrigation system while the second GPS receiver is located on a moving portion of the irrigation system. The first GPS receiver compares the GPS receiver reported position against the actual position and reports by wire or radio link the position differences to the second GPS, where the differences are used to remove errors from the second receiver's measured position.

An integrated guidance system for use in swath guidance applications combines the display of swath navigation information with swath guidance system information. A processor receives information from an external positioning system such as a Global Positioning System receiver and generates course correction data derived from swath parameters selected by the user from a displayed menu of options using a control interface that is integrated with the display and processor or is located externally. The swath navigation information is displayed graphically and numerically. The entire apparatus is compact and mountable within the operative view of the user as he operates the equipment to be guided, thereby reducing hazard and navigational error.

A method and apparatus for demodulating and decoding an MSK signal utilizing synchronous accumulation and simultaneous synchronization of reference carrier and MSK data clocks enables a GPS correlator channel in a multi-channel GPS receiver to be used for processing MSK signals. The PRN code epochs are synchronized with the MSK data clocks and the process of de-spreading with a PRN code is disabled in order to obtain coherent MSK demodulation without corrupting the MSK signal with a PRN code within the channel.

An apparatus for extending the practical lengths over which coaxial cables can be used to transfer signal information from a Global Positioning System (GPS) antenna to a GPS receiver. The apparatus converts the GPS signal frequency of 1.57542 GHz to a frequency low enough to be transferred long distances over coaxial cables without significant signal attenuation and then converts the signal back to the original frequency without the introduction of frequency errors. The invention is not restricted from being used at other frequencies where system design parameters makes it practical.
