摘要： A sensing sub-assembly for use with a drilling assembly includes a cylindrical body and at least one sensor coupled to the cylindrical body. The cylindrical body includes an internal flow channel extending therethrough, which is configured to channel a first fluid therethrough and a recessed cavity defined therein, which is configured to receive a continuous stream of a second fluid therethrough. The recessed cavity is coupled in flow communication with an ambient environment exterior of the cylindrical body,and the second fluid flows within the ambient environment. The at least one sensor is configured to determine characteristics of the second fluid in the continuous stream that flows through the recessed cavity.

摘要： A sensing system (200) for a resource recovery system is provided. The sensing system (200) includes at least one sensing sub-assembly (201) and a sensing computing device (105). The sensing computing device (105) is configured to receive, from the at least one sensing sub-assembly (201), at least one signal that includes at least one pulse having at least one pulse peak. The sensing computing device (105) is also configured to identify the at least one pulse peak which has a magnitude and a signal-to-noise ratio, and retrieve the at least one pulse peak from the at least one signal using the magnitude and the signal-to-noise ratio of the at least one pulse peak. The sensing computing device (105) is further configured to store the at least one pulse peak within a database that includes one or more pulse peaks, and generate a component report that identifies one or more changes of at least one component.

摘要： This invention provides a method and a device for detecting occlusion and/or reopening of an artery of a body caused by a changing pressure applied on the artery as well as a system for measuring the systolic blood pressure of an artery of a body. The method comprises the steps of: obtaining a blood flow signal indicative of a change of the blood flow in the artery caused by the changing pressure,using a Doppler Ultrasound transducer attached to the exterior of the body; deriving, from the blood flow signal, at least one variable of a first variable indicative of the magnitude of the blood flow and a second variable indicative of the periodicity of the blood flow; and detecting the occlusion and/or reopening of the artery on the basis of the at least one variable. In this way, the occlusion/reopening of the artery can be detected automatically. Since the need to manually detect the occlusion and reopening of the artery by listening with a stethoscope or a Doppler probe is eliminated, the detecting result is more predictable and repeatable, and therefore also more accurate.

摘要： This invention provides an ultrasound probe, a device and method for acquiring a blood flow signal of an artery and a system for measuring systolic blood pressure. The ultrasound probe comprises a plurality of ultrasound transducers, wherein each of the plurality of ultrasound transducers is configured to obtain an echo signal by transmitting an ultrasonic wave, receiving an ultrasonic wave and transforming the received ultrasonic wave into the echo signal. The device for acquiring a blood flow signal of an artery comprises the ultrasound probe, wherein the ultrasound probe is intended to be attached to the exterior of the body. The device further comprises: a first deriving unit configured to derive, from each obtained echo signal, at least one Doppler signal, the at least one Doppler signal being associated with the ultrasound transducer obtaining the echo signal and being indicative of information about Doppler shift of the echo signal; a selecting unit configured to select a Doppler signal from the derived Doppler signals according to a predefined condition, the selected Doppler signal being indicative of the at least one characteristic of the blood flow in the artery of the body. In this way, the need for accurate localization of the artery by means of manual adjustment is eliminated on the proviso that the ultrasound probe is attached in such a way that the artery lies within the footprint of the ultrasound probe.
