摘要： An elongate component such as a drill string of drill pipes connected by joint sections inside a bore is sensed using at least one set of electromagnetic coils, the coils within the set being arranged at different angular positions around the bore facing the bore. There may be at least two sets of coils separated along the axial direction of the bore. Electrical oscillations are generated in the coils to produce oscillating electromagnetic fields that interact with the contents of the bore. A parameter of the electrical oscillations generated in each coil is detected. The detected parameters may be used to derive both (1) a measure of the axial position along the bore, and (2) a measure of the lateral position. The detected parameters may be used to derive a measure of electromagnetic properties of the contents of the pipe in a region adjacent each coil, thereby imaging the contents of the pipe.

摘要： A sensor unit for a fingerboard latch assembly comprising a latch bracket and a latch rotatably mounted on the latch bracket comprises a sensor arranged to sense the orientation of the latch and a wireless, optical or other communication unit arranged to communicate the orientation of the latch sensed by the sensor. The sensor unit may be mountable on the latch and comprise an orientation sensor arranged to take measurements that are dependent on the orientation of the sensor unit, and a processor arranged to derive an orientation signal representing the orientation of the latch from the measurements, the communication unit being arranged to communicate the orientation signal. A monitoring system receives the sensed orientations from plural sensor units.

摘要： A sensor arrangement for a rotatable element comprises two coils capable of being driven by oscillatory drive signals to generate electromagnetic fields. The coils are in different positions overlying a cylindrical portion of the rotatable element that has a target feature configured to interact with the generated electromagnetic fields when the target feature is aligned with the coils. Alignment between the target feature and the coils occurs at angular positions of the rotatable element that are offset for respective coils. Thus, by detecting a characteristic of the signals developed across the coils allowing derivation of an angular velocity signal representative of angular velocity. Also, the degree of interaction between the target feature and the electromagnetic fields varies with the axial position of the rotatable element, differentially between the coils, allowing derivation of an axial position signal representative of the axial position of the rotatable element.

摘要： A safety sensing system implements a method for a person in an industrial environment comprises providing a personnel locator device (10) for location on a person and a reference system comprising a plurality of nodes (20) located at predetermined locations in the industrial environment (100). Radio ranging signals are transmitted between the nodes (20) and the personnel locator device (10) and measurements of times of flight of the radio ranging signals are derived. The location of the personnel locator device (10) is calculated based on the measurements of the times of flight of the radio ranging signals and reference information representing the predetermined locations of the nodes (10). It is determined if the calculated location of the personnel locator device (10) is within one or more danger zones in the industrial environment (100) and a warning signal is output in response thereto.

摘要： A sensor assembly is provided for a fingerboard latch assembly that comprises: a latch bracket; bolts for mounting the latch bracket to a fingerboard; a latch; and a bracket pin rotatably supporting the latch on the latch bracket to allow rotation of the latch between an open position and a closed position. The sensor assembly has a mounting arrangement that mounts to the bolts, holding a closed-position proximity sensor probe facing downwardly for sensing proximity of a crank portion of the latch and/or the piston head in the closed position, and also holding an open-position proximity sensor probe facing forwardly for sensing proximity of an arm of the latch in the open position.
