Abstract: Methods and apparatus to track a blade are disclosed. A disclosed example apparatus includes a blade that is pivotable, first and second optical targets operatively coupled to the blade, and a first camera for collecting first imaging data of the first optical target within a first field of view. The example apparatus also includes a second camera for collecting second imaging data of the second optical target within a second field of view. The example apparatus also includes a selector to select at least one of the first or second imaging data, and a processor to determine an orientation of the blade based on the selected imaging data.

Abstract: A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. One or more satellite navigation receivers are associated with beam to determine a position and an attitude of the beam. One or more row units are suspended from the beam, such that the position of nozzle or nozzles on each row unit can be adjusted simultaneously and dynamically in multiple dimensions to maintain a target spacing between the nozzle and ground and the nozzle and a plant or row of plants.

Abstract: In accordance with one embodiment, a row unit for an agricultural vehicle comprises an upper carriage that is movable or slidable with respect to a generally horizontal beam of the vehicle. The row unit has vertical supports, where each vertical support has an upper end connected to the upper carriage and a lower end opposite the upper end. The row unit further comprises a lower carriage that is connected to the lower end of the vertical supports, such that the upper carriage determines a lateral position of the lower carriage with respect to the beam.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for efficient material application. An example landscape treatment apparatus includes a main carrier tank to store a solvent, a concentrate tank to store a solute, and a first mix tank to receive the solvent and the solute as a first mixture. The example apparatus further includes a second mix tank to receive the solvent and the solute as a second mixture, where the first mix tank is to receive the solvent and the solute in alternation with the second mix tank receiving the solvent and the solute. The example apparatus also includes a boom to apply the first mixture and the second mixture to a landscape via a plurality of nozzles, where the boom is to apply the first mixture and the second mixture in alternation.

Abstract: An agricultural vehicle comprises a left frame and a right frame. A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. One or more satellite navigation receivers are associated with beam to determine a position and an attitude of the beam. In on configuration, at least one row unit suspended from the beam, where each row unit has a respective planting device with an adjustable position in one or more dimensions with respect to the beam for precise application or variable application of seeds within the rows or field.

Abstract: A mobile machine includes a set of human presence sensors that comprise one or more optical sensors, one or more thermal sensors, and an additional sensor that senses a characteristic of a human. The contribution of the various sensor values generated by the sensors is determined based on environmental conditions. A human presence metric, indicative of human presence, is generated from the contributions of the various sensor signals.

Abstract: An agricultural vehicle comprises a left frame and a right frame. A left wheel is rotatable with respect to the left frame and a right wheel is rotatable with respect to the right frame. A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. A data processor estimates a reference point on or below the vehicle and an angular orientation or attitude of the beam relative to the reference point based on positions of location-determining receivers associated with the beam. An upper carriage is laterally movable along the beam. A lower carriage is suspended from the upper carriage by a plurality of vertical supports, such that a target lateral position of the upper carriage establishes an actual lateral position of the lower carriage.

Abstract: Within a mobile station data message, the mobile transceiver reads an observed country code of a visited wireless network to determine a country of operation of the mobile transceiver. The mobile transceiver determines if the observed country code is equal to a stored country code in a subscriber identity module of the mobile transceiver. If the observed country code differs from the stored country code, the mobile transceiver transmits an inquiry data message to a central server via the wireless network to inquire as to whether or not the mobile transceiver is authorized to operate within the observed country. In response to the inquiry, the mobile transceiver may receive mobile profile data related to wireless access or authorized features of the mobile transceiver.

Abstract: A tractor includes an electronic tractor controller. A baler includes an electronic baler controller. The baler controller submits a halt signal to the tractor controller when a bale size is equal to or exceeds a first predetermined size. The baler controller generates a tractor halt signal in response to certain conditions of the baler system and the tractor controller preventing tractor motion in response to the halt signal. When the baler controller is generating the halt signal, tractor motion is enabled if the operator commands the tractor to move by manipulating the command device, and within a certain time period of said command being issued, the baler controller generates a tractor motion enabling signal in response a status of the baler system. When the baler controller is generating the halt signal, tractor motion is enabled if the operator moves the tractor command device in a special manner.
