Vehicles, systems, and methods for navigating or tracking the navigation of a materials handling vehicle along a surface that may include a camera and vehicle functions to match two-dimensional image information from camera data associated with the input image of overhead features with a plurality of global target locations of a warehouse map to generate a plurality of candidate optical targets, an optical target associated with each global target location and a code; filter the targets to determine a candidate optical target; decode the target to identify the associated code; identify an optical target associated with the identified code; determine a camera metric relative to the identified optical target and the position and orientation of the identified optical target in the warehouse map; calculate a vehicle pose based on the camera metric; and navigate the materials handling vehicle utilizing the vehicle pose.

The disclosure generally pertains to systems and methods for use of a vehicle to conduct a site survey. An example method can include receiving navigation guidance to move a vehicle along a pre-defined path on a property for executing a site survey operation of the property. The site survey operation can include a staking procedure performed by a robotic arm attached to the vehicle, an image capture procedure performed by use of a camera in the vehicle, and/or a subterranean scanning procedure for detecting a buried object. In an example implementation, the staking procedure can include inserting at a first location on the property, a stake having affixed thereon, a barcode label. A barcode scanner can be used to read the barcode label for obtaining information associated with an object present at the first location.

A system, method, service and wireless location-establishing device are disclosed, which locates its position by a plurality of means, including GPS satellite interrogation and triangulation. Alternative methods of location establishment include triangulating location data from nearby location-established objects such as WiFi or cell site towers, as well as from other present Invention location establishing devices (“Survey Eggs”). Once location has been established, the device can transmit and receive a variety of data based upon location, profile, and other factors, facilitating novel interactions and transactions.

An angle sensor includes first and second detection units and an angle detection unit. Each of the first and second detection units generates two detection signals. The first and second detection units are arranged in a positional relationship that establishes predetermined phase relationships among the detection signals they generate. The angle detection unit includes first and second computing circuits and an angle computing unit. The first and second computing circuits generate first and second signals in each of which an error component corresponding to a fifth harmonic contained in the detection signals is reduced. The angle computing unit calculates a detected angle value on the basis of the first and second signals. The angle computing unit performs correction processing for reducing an error occurring in the detected angle value due to an error component corresponding to a third harmonic contained in the detection signals.

This is a method and apparatus for use therein that provides a novel means to mark the location of a utility of a home or other building. The method comprises attaching a stencil marker to the form at the location of a utility before the slab is poured, pouring the slab and allowing it to cure, and then removing the form and stencil marker. In one or more embodiments, the stencil marker comprises a lightweight material capable of being folded without failure. The location of the fold is so that at least one indicator hangs down from the form and to the concrete.
