Abstract: Multiple cameras are used for tool positioning, as-built documentation, and/or personnel monitoring in construction site. A camera unit comprises one or more imaging devices, a processing computer, and a communication device. The camera units are placed at multiple locations in a construction site to cover an area. The camera units are self-positioned by detecting a calibration target that moves within a working volume. The camera units can detect and calculate positions of objects, including measurement sticks, tools, personnel, etc., in the area.

Abstract: Various embodiments provide novel tools and techniques for position and/or motion tracking, including without limitation solutions that can be used for excavation and similar applications. In a particular aspect of some embodiments, a communication device with a camera may be provided to track the position and motion of a stick of an excavator or reference features located on a stick of an excavator. A location of a bucket of an excavator may then be calculated relative to the stick or reference features on the stick of the excavator. Thus, an operator of the excavator can use the communication device to effectively and efficiently track the location of the excavator bucket without the need for a second person to provide instructions about the location of the bucket.

Abstract: A GNSS antenna assembly for connection to a receiver circuit of a hardware front-end. The assembly may include a multiplayer antenna and a ground plane board. The antenna board may contain an L1 patch antenna of a first width, an L2 patch antenna of a second width greater than the first width, and a ground plane of a third width that is equal to or greater than the second width. The ground plane board may include a ground plane of a fourth width that is greater than the third width. Upon assembly, contact pads of the antenna board, which are in conductive contact with the ground plane of the antenna board, are in conductive contact with contact pads of the ground plane board.

Abstract: An antenna includes a dielectric substrate, a circular patch overlying the dielectric substrate, and a metamaterial ground plane. One or more antenna feeds are coupled to the circular patch. The antenna feeds may include impedance transformers. The metamaterial ground plane includes a plurality of conductive patches and a ground plane. The conductive patches are arranged along a first plane below the circular patch and are separated from the circular patch by at least the dielectric substrate. The conductive patches are arranged in a pattern that provides circular symmetry with respect to a center of the circularly polarized antenna. The ground plane is arranged along a second plane and is electrically coupled to at least a first portion of the conductive patches. One or more of the conductive patches and the ground plane are coupled to ground.

Abstract: A center pivot irrigation system is described that includes a controller that makes use of a particular flow rate of input water to deliver differing or variable depths of irrigation to two or more user-defined areas under a pivot irrigator. The controller operates to pulse control valves for the nozzles/sprinkler heads on and off as the sprinkler arm rotates. The valve pattern along the span of the sprinkler arm is chosen during each operating cycle such that the total water flow through all the open valves matches the flow rate of the input or supply water to the pivot irrigator. To ensure the variable application depth, the speed may be changed during valve duty cycles. A farmer may define an irrigation plan that defines the variable rate irrigation (VRI) zones and also defines exclusion or no spray zones in which no irrigation should occur.

Abstract: A method for reporting as-built data of a project is disclosed. In one embodiment, at least one attribute of a task perform by a handheld tool is recorded at the handheld tool. The attribute of the at least one task is reported via a wireless communication link to an information management system. The at least one attribute of the task is used to update a record of a project stored at the information management system.

Abstract: A method for displaying images using an AR device. GNSS position data is received based on wireless signals received from a GNSS satellite. Based on the GNSS position data, a first GNSS point within a geospatial frame is determined within a first time range and a second GNSS point within the geospatial frame is determined within a second time range. Based on camera POS data, a first AR point within an AR frame is determined within the first time range and a second AR point within the AR frame is determined within the second time range. One of the frames is shifted such that the second GNSS point is aligned with the second AR point. An angle formed by the GNSS points and the AR points is calculated. One of the frames is rotated by the angle.

Abstract: The present invention is directed to systems and methods for managing and regulating construction sites, particularly in light of inclement weather or hazardous conditions. In many jurisdictions, extreme weather conditions, including excessive precipitation, render a construction site closed, or unworkable, thereby wasting time and resources. This invention provides a system and processes to monitor, detect and measure precipitation on a construction site, and even several sub-sites on the construction site, from a remote location. The system and processes of the present invention also provide features to further investigate precipitation levels in a more efficient manner than conventionally available and to communicate the construction site conditions, e.g., precipitation levels, and whether the site has met the required regulatory thresholds for inspection. Moreover, the present invention may be used to determine the magnitude of rain events, and potential liabilities associated therewith.

The at least one network message relates to stations of a network of stations within a region. The at least one cluster message relates to a subset of stations within the region. Network elements are extracted from the network message and cluster elements are extracted from the cluster message. Network elements and cluster elements are used to determine a position of a rover within the region.

Abstract: Efficient towed implement guidance to a desired path is achieved by guiding a towing vehicle toward a path on the opposite side of a desired path, then guiding the vehicle back to the desired path. Efficient forward implement guidance to a desired path is achieved by guiding a pushing vehicle along a tractrix. A vehicle leaves a straight line along a tractrix to keep a rear implement on the line as long as possible.
