  • Patent number: 10324187
    Abstract: A three-dimension position tracking system is presented. The system includes transmitters and receivers. A transmitter scans continuous or pulsed coherent light beams across a target. The receiver detects the reflected beams. The system recursively determines the location of the target, as a function of time, via triangulation and observation of the time-of-flight of the incoming and outgoing beams. The transmitter includes ultra-fast scanning optics to scan the receiver's field-of-view. The receiver includes arrays of ultra-fast photosensitive pixels. The system determines the angles of the incoming beams based on the line-of-sight of the triggered pixels. By observing the incoming angles and correlating timestamps associated with the outgoing and incoming beams, the system accurately, and in near real-time, determines the location of the target.

  • Patent number: 9945096
    Abstract: A system and method for automatically adjusting blade pitch in crawler dozers, motor graders, and other bladed work vehicles includes estimating a current tractive force of the work vehicle utilizing one or more controllers that establish whether the current tractive force of the work vehicle can be reduced by rotating the blade to an optimized pitch angle. A command is transmitted from the one or more controllers to a blade actuation system to rotate the blade to the optimized pitch angle. The method may be performed iteratively to repeatedly adjust the blade pitch to optimized angles as the work vehicle operates and conditions affecting the optimal blade pitch angle vary.

  • Patent number: 9904283
    Abstract: Precision docking is one of the most important tasks for drones and surface robots to charge themselves and load/unload packages. Without accurate docking, surface robots and drones will miss their charging pad or charging contacts and cannot automatically charge themselves for later tasks. Described is a system using coded light to guide the precision docking process for drones and ground robots. More specifically, the system uses projectors to project temporal identifiers for space partitioned by pixel projections. Different space partition gets a different identifier. By using a simple light sensor on a drone or a ground robot, the drone or the ground robot can know its precise location in the space and therefore knows where to move for a precise docking. Depending on docking precision requirement, the coded light precision may be adjusted by using projectors with different resolutions.

  • Patent number: 9818292
    Abstract: A control system for a rotary laser receives control information transmitted by a communications terminal via a first repeater coupled to the communications terminal and transmits the control information to a controller via a second repeater disposed on a rotary laser. The controller regulates an operating state of the rotary laser based on the control information. The control system enables the communication terminal to wirelessly control and operating state of the rotary laser via cooperation between the first repeater and the second repeater so as to achieve a remote control and to avoid use of a dedicated remote control alone, reduce the system costs and be carried easily.

    Abstract: An aggregate spreading system includes a dump truck that has a cab and a bed. The bed may contain an aggregate. A transport unit is coupled to the dump truck. The transport unit is positioned on the bed to urge the aggregate forwardly in the bed. A distribution unit is coupled to the dump truck. The distribution unit is positioned on the bed to receive the aggregate from the transport unit. Thus, the distribution unit distributes the aggregate onto a support surface. The distribution unit levels the aggregate on the support surface when the aggregate has been released onto the support surface.

  • Patent number: 9799045
    Abstract: Methods, systems, and techniques for determining the vertical alignment of an infrastructure corridor having a certain horizontal alignment involve using a processor to model the cost of constructing the infrastructure corridor as a function of cost variables that vary with the vertical alignment of the infrastructure corridor. The processor looks up the cost variables at vertical offsets corresponding to certain vertical alignments of the infrastructure corridor and determines the cost of constructing the length of road at elevations located between pairs of the vertical offsets by interpolating from the cost variables at the vertical offsets; the interpolation may be linear. The processor determines, subject to infrastructure corridor design constraints, the vertical alignment of the infrastructure corridor from the cost of constructing the infrastructure corridor at the vertical offsets.
