Abstract: Disclosed is a method and apparatus for digital control of a milling machine drum to minimize road material milled using complex geometry. A digital representation of a surface and/or subsurface of a road is loaded into a controller. Road defects are identified based on the digital surface, by comparing defect digital characteristics with the digital surface. A minimum removal map can be generated using the defect digital characteristics. A milling tool path can then be generated to minimize material removal, based on the minimum removal map. The mill depth and movement of a mill drum can then be controlled based on the milling tool path.

Each device node of the aggregated node group has multiple power level states. One of a plurality of roles of the device node is determined based upon the information. Each role has an associated power level state. The power level state associated with the role or function of the device node is enabled. The device node is instructed to actuate the determined role.

Abstract: In one example, a method of relaying energy to device nodes is disclosed. The method includes transmitting energy waves into an aggregated node group with multiple device nodes. The transmitted energy waves are to actuate the device nodes into a higher power state and in part for storage by the device nodes. Energy streams reflected by the aggregated node group may be captured to indicate actuated and non-actuated device nodes. The method determines a target low power state device node from the non-actuated low power state device nodes and determine neighboring higher power state device nodes proximate to the target low power state device node. A communication signal may be transmitted to the neighboring higher power state device nodes directing them to relay the stored energy to the target low power state device node to actuate the target low power state device node into a higher power state.

Abstract: Systems and methods are described herein for detecting connections between components, such as 3D-printed components, using RFID tags, readers, and/or writers. For example, an RFID reader may read an identification code from an RFID tag that is at least partially 3D-printed as part of a first 3D-printed component to verify the connection to a second 3D-printed component. In various examples, the RFID reader may detect different identification codes depending on whether the first 3D-printed component is correctly connected to the second 3D-printed component, incorrectly connected to the second 3D-printed component, and/or connected to the second 3D-printed component in the past.

Abstract: The present inventors have recognized that hydraulic cylinders for raising and lowering ground engaging tools of an implement can be synchronously controlled with respect to a prioritized primary set of tools, such as a section of tillage shanks for ripping compacted soil, which cylinder adjustment affects all other sections due to the arrangement of the primary set on the frame. A user can electronically command new ground engaging depths for the primary set and/or any secondary set of ground engaging tools. If the primary set is updated, the system can synchronously control the primary set and the other sections to adjust respective cylinders to achieve desired depths. However, if only a second set is updated, and not the primary set, the system can control only the second set to adjust its cylinder to the desired depth without affecting the primary set or any other second set.
