摘要:
A smart device is disclosed which contains a digital camera with an active electronic viewscreen that displays the detected image, in which the camera can sense laser light beams. The smart device has the capability receiving and executing an application program that allows the camera to be used as a grade elevation detector, in which the camera can sense a laser light beam that effectively forms a plane of laser light which defines an “on-grade” elevation for a jobsite. The user can determine this on-grade elevation by running the APP and viewing the display screen to find the (rotating or static) laser beam. An automated APP system can capture the on-grade elevation using a sequence of images that include a grade rod measurement paired with laser beam intensity detection images.

An example method for providing a user with service technical data is provided. A server stores original service technical data and annotated data in a server where the annotated data is associated with the original service technical data. The server determines an access level of the user such where the access level of the user determines what service technical data may be sent. A portion of the service technical data is sent from the server to a device associated with the user, based at least in part on the access level of the user. The server also receives additional annotated data generated by the user where the additional annotated data is associated with the original service technical data.
摘要:
Methods and apparatus are described for processing a set of GNSS signal data derived from code observations and carrier-phase observations at multiple receivers of GNSS signals of multiple satellites over multiple epochs, the GNSS signals having at least two carrier frequencies, comprising: forming an MW (Melbourne-Wübbena) combination per receiver-satellite pairing at each epoch to obtain a MW data set per epoch, and estimating from the MW data set per epoch an MW bias per satellite which may vary from epoch to epoch, and a set of WL (widelane) ambiguities, each WL ambiguity corresponding to one of a receiver-satellite link and a satellite-receiver-satellite link, wherein the MW bias per satellite is modeled as one of (i) a single estimation parameter and (ii) an estimated offset plus harmonic variations with estimated amplitudes.

Devices, systems, and methods for managing a cargo transaction are disclosed. By transmitting and integrating consignment data and real-time cargo status data including data collected from a GPS-enabled monitoring device to a visual cargo server, a visual cargo data is produced. The visual cargo data is contextualized by integrating with contextual data obtained from one or more contextual servers.

In a method for refining a position estimate of a low earth orbiting (LEO) satellite a first position estimate of a LEO satellite is generated with a GNSS receiver on-board the LEO satellite. Corrections are received at the LEO satellite. The corrections are processed on-board the LEO satellite such that a corrected LEO satellite position estimate of the LEO satellite is generated for the first position estimate.

A hook block sensor assembly is disclosed. In one embodiment, the hook block sensor comprises a housing configured to removably couple about a lifting hook of a lifting device, a first global navigation satellite system (GNSS) receiver coupled with the housing and configured for determining a hook block sensor assembly position in three dimensions, a load monitor coupled with the housing and configured for monitoring a load coupled with the lifting hook, including monitoring a load position and a load orientation of the load and a wireless transceiver coupled with the housing and configured for wirelessly providing information including the load position, the load orientation, and the hook block sensor assembly position, to a display unit located apart from the hook block sensor assembly.

A method of determining the orientation of a robotic machine at a worksite contemplates providing a target on the machine, moving the target to a first position on said machine, determining the location of the first position in the worksite, moving the target to a second position on said machine, and determining location of the second position in the worksite. The first and second positions are known with respect to the machine. Finally, a vector between the first and second locations defines the orientation of the machine with respect to the worksite. The target may be moved to additional positions on the machine.

An image-based georeferencing system comprises an image receiver, an image identification processor, a reference feature determiner, and a feature locator. The image receiver is configured for receiving a first image for use in georeferencing. The image comprises digital image information. The system includes a communicative coupling to a georeferenced images database of images. The image identification processor is configured for identifying a second image from the georeferenced images database that correlates to the first image. The system includes a communicative coupling to a geographic location information system. The reference feature determiner is configured for determining a reference feature common to both the second image and the first image. The feature locator is configured for accessing the geographic information system to identify and obtain geographic location information related to the common reference feature.

In a method of milling asphalt, a relative elevation of an unmilled asphalt pavement surface adjacent to an area to be milled is sensed with respect to a milling machine body and rotatable milling drum of the milling machine. An elevation of a bottom surface of the rotatable milling drum is determined using a computer processor. Based on a map, stored in a computer memory, of a design surface specifying a design elevation of a milled surface over the area to be milled, the elevation of the milling machine body and the rotatable milling drum are automatically adjusted such that the rotatable milling drum mills the asphalt surface to the design elevation over the area to be milled.
