Patent number: 11467316Abstract: Systems, methods, and computer-readable media for in-situ calibration of magnetic field measurements. In some examples, a method can involve generating a magnetic field via a magnetic field source that is coupled to a downhole tool. The magnetic field source can be located within a fixed distance from one or more sensors coupled to the downhole tool. The method can also involve obtaining respective field measurements of the known magnetic field from the one or more sensors, and comparing the respective field measurements from the one or more sensors with respective reference measurements previously obtained from the one or more sensors to yield respective comparisons. The method can then involve determining, based on the respective comparisons, a respective sensitivity drift for each of the one or more sensors.Type: GrantFiled: December 12, 2016Date of Patent: October 11, 2022Assignee: Halliburton Energy Services, Inc.Inventors: Hsu-Hsiang Wu, Wenquan Li, Faisal Farooq Shah, Brian Roberson

Publication number: 20110162456Abstract: An ultrasonic dimensioning system and method by which objects can be quickly and accurately measured (dimensioned). The system includes at least a stable object support surface, a number of ultrasonic receivers, and an ultrasonic transmitter. The ultrasonic transmitter is preferably part of a pointer device that is properly positioned relative to an object to be measured, the proper position(s) depending on the shape of the object. Subsequent transmission of ultrasonic pulses (waves) from the pointer device are received by the ultrasonic receivers. The time intervals between transmission and reception of the ultrasonic pulses (waves) are used to determine the distance of the pointer from the receivers, which distances are subsequently used to calculate the dimensions/volume of the object.Type: ApplicationFiled: March 16, 2011Publication date: July 7, 2011Applicant: METTLER-TOLEDO, INC.Inventors: Wenquan Li, Philip M.
