摘要： A system (50) for tracking an object (1) comprises a magnetic field source (10) configured to be fixed to this object (1); a magnetometric data collection unit (20) that uses magnetic field sensors (22) fixed at predetermined positions on a support (23) to form an array (21), and that includes a sensor control unit (25) for controlling the magnetic field sensors (22); a data processing unit (30) configured to receive the magnetic field data from the sensor control unit (25) and to calculate from these data position coordinates of the magnetic field source (10) with respect to the array (21) forming a vector of such position coordinates which minimizes the distance between magnetic field values expected at the sensor positions (22) and magnetic field values collected by the collection unit (20), wherein the magnetic field source (10) is arranged to generate a local magnetic field (4), at the magnetic field sensors (22), of intensity set between 5 and 500 microtesla, so that the magnetic field sensors (22) detect both the local magnetic field (4) and the geomagnetic field (5), and wherein the data processing unit (30) is configured to recognize contributes of the local magnetic field (4) and of the geomagnetic field (5) in the magnetic field data, and is configured to determine location and of orientation coordinates of the magnetic field source (10) with respect to the array (21), as well as orientation coordinates of the array (21) with respect to the geomagnetic field (5). This way, an accurate tracking can be obtained of the displacements of the object (1) even if the array (21) is connected to a support that is movable with respect to an absolute reference system integral to the geomagnetic by fixing array to the subject's head.

摘要： The present disclosure provides a system, an apparatus and a method for detecting line-attached tools in an above-surface portion of a well for use during well-work overs and/or interventions. The system includes the apparatus which comprises: a body for housing at least one magnetic-field generator and at least one magnetic-field sensor; and a tubular portion that is configured to be housed within the body. The tubular portion has a bore for receiving the line-attached tools and the at least one magnetic-field sensor is configured for detecting changes in the magnetic field caused by the line-attached tool approaching, moving through and/or moving away from the body. The system may further include a processor unit for receiving one or more signals from the at least one magnetic-field sensor and for determining the location and/or one or more dimensions of the line-attached tool while approaching, moving through or moving away from the body.

摘要： A method for calibrating a 3D printer includes the steps of providing information obtained in a factory calibration indicating a center of an inner diameter of a tip orifice in a metal extrusion nozzle and a center of a tip surface for the nozzle and inductively sensing the nozzle with an eddy current sensor when secured to a print head on a gantry or robotic arm of the 3D printer to identify a sensed location of the center of the tip surface of the nozzle. The method includes determining a location of the center of the inner diameter of the tip orifice on the nozzle on the print head and utilizing the provided information to locate the center of the inner diameter of the tip orifice.

摘要： Cable-actuated position sensors are described that employ multiple block and tackle arrangements to measure displacement of a draw wire or flexible cable. The disclosed sensors are relatively small and inexpensive. The disclosed sensors may also be used as part of a servo motor, or in conjunction with gear motors to provide positional information for operation of the gear motor.

摘要： An electronic pallet (e-pallet) includes a superstructure mounted to a wheeled base platform. A tether device defines an articulation angle with respect to a leading edge of the superstructure, and is grasped by an operator towing the e-pallet. A motor connected to driven road wheels transmits a drive torque to the road wheels responsive to motor control signals, including a desired yaw rate and ground speed. A speed sensor, angle sensor, and length sensor are respectively configured to determine an actual ground speed of the e-pallet, the articulation angle, and a length of the tether device. An electronic controller, in response to the input signals, generates the motor control signals using proportional-integral-derivative (PID) control logic. Coupled lateral and longitudinal dynamics control loops respectively determine the desired yaw rate and ground speed to accommodate for motion of the operator.

摘要： A frame control system for an agricultural implement includes a first sensor configured to be coupled to a sub-frame of the agricultural implement and directed toward a soil surface. The first sensor is configured to emit a first output signal toward the soil surface and to receive a first return signal indicative of a first height of the sub-frame above the soil surface. The frame control system also includes a first sub-frame actuator configured to be coupled to the sub-frame and to a main frame of the agricultural implement. The first sub-frame actuator is configured to control a first position of the sub-frame relative to the main frame along a vertical axis. In addition, the frame control system includes a controller configured to control the first sub-frame actuator such that a difference between the first height and a target height is less than a threshold value.
