摘要： Systems and methods are provided for determining and distinguishing buried objects using Artificial Intelligence (Al). In an exemplary embodiment, electromagnetic data related to underground utilities and communication systems is collected and provided to a Deep Learning model to build a training set. The Deep Learning model may be trained based on collected sets of Training Data, testing data, and/or user predefined classifiers. The Deep Learning model may use thresholds to determine if a set of data falls within a specific class. Classes may include gas, electric, water, cable, communications lines, or other buried utility and communication classes. Electromagnetic data collected may include multi-frequency measurements, phase measurements, signal strength measurements, and other related measurements. Data may be collected from locators, Sondes, transmitting and receiving antennas, inductive clamps, electrical clips, and satellite systems such as GPS, and other sources. Determined class data may organized and displayed to a user.

摘要： Apparatus, systems and processes for detection of objects representing possible projectile hazards in areas of high magnetic fields such as those potentially hazardous ferrous objects which may be moved within the region of forceful magnetic attraction by magnetic resonance imaging (MRI) scanners. The systems and process may include multiple magnetic field sensors and multiple time of flight sensors positioned around a passageway. The time of flight sensors may facilitate determination of movement (e.g., speed and/or direction) of the potentially hazardous ferrous object to provide enhanced accuracy of threat detection.

摘要： In one example, a sensor comprising a vapor cell including a vapor of alkali atoms is disclosed. The sensor further comprises a system configured to direct electromagnetic (EM) radiation of one or more frequencies into the vapor cell and incident on the vapor of alkali atoms. The EM radiation of one or more frequencies is configured to prepare the alkali atoms from a first quantum state to a Rydberg state. The alkali atoms prepared in the Rydberg state comprise an orbital angular momentum quantum number that is at least the number of quanta of the one or more frequencies. The sensor further comprises a detector configured to detect a response of the alkali atoms to incident electromagnetic radiation after the alkali atoms are prepared in the Rydberg state.

摘要： A system and for providing a bore sight in a piercing tool. A transmitter emits a magnetic field. The flux lines which emanate along the transmitter axis are substantially straight. A receiver at a remote, target location can detect these flux lines. The receiver and transmitter are oriented such that the substantially straight flux line are along an intended bore path. Then, a piercing tool or other boring tool is oriented along the same path and a bore is created.
