  • Integrated computational elements with frequency selective surface
    Patent number: 10247662
    Abstract: Technologies are described for providing optical analysis systems using an integrated computational element that has a surface patterned to selectively reflect or transmit different wavelengths by differing amounts across a spectrum of wavelengths. In one aspect, a measurement tool contains an optical element including a layer of material patterned so that the optical element selectively transmits or reflects, during operation of the measurement tool, light in at least a portion of a wavelength range by differing amounts, the differing amounts being related to a property of a sample. The wavelength range can include wavelengths in a range from about 0.2 ?m to about 100 ?m. Additionally, the sample can include wellbore fluids and the property of the sample is a property of the wellbore fluids.

  • HUMAN-MACHINE INTERFACE (HMI) ARCHITECTURE
    Publication number: 20190004510
    Abstract: An autonomous driving vehicle (ADV) is operated using a human-machine interface (HMI). The web server provides the HMI to a computing device in response to an input received from the computing device. An ADV command is entered into the HMI and passed to an interface of the web server. In response to receiving the ADV command, the web server calls a remote procedure call to a proxy server in a backend server for processing by a perception and control module of the ADV. Results of the ADV command are received by the web server interface and stored in results memory with a unique identifier. The web server interface opens a socket that accesses the results memory. If the results memory changes, the socket reads the results memory and provides the ADV command results to the HMI. Multiple HMIs can simultaneously communicate with the web server interface and socket.

  • SYSTEM AND METHOD FOR THE DETECTION AND TRANSMISSION OF DOWNHOLE FLUID STATUS
    Publication number: 20180363413
    Abstract: Systems and methods for signaling the detection of a fluid change in a wellbore can be used during wellbore operations, such as cementing a casing in the wellbore. The systems and methods involve using burst discs to provide a pressure pulse that can be detected uphole and there by provide a signal related to when a fluid change has reached a predetermined position in the wellbore. The burst discs can be activated to prevent fluid flow in a portion of the wellbore by a sensor that detects a property that is different between two fluids. Once activated, the pressure of the fluid on the burst discs subsequently ruptures the burst disc and creates the pressure pulse.

  • Utilizing fluid phase behavior interpretation to increase sensor measurement information accuracy
    Patent number: 10012763
    Abstract: Various embodiments include apparatus and methods to utilize fluid phase behavior interpretation to increase sensor measurement accuracy. In some embodiments, a downhole sensor measures detector responses within a measurement sample of a downhole fluid. The measured detector responses are acquired from the downhole sensor. A correlation factor is generated as a scalar product between a vector of the measured detector responses and a vector of known responses. The correlation factor has a value within a fixed interval, one end of the fixed interval corresponding to a high correlation status and an opposite end of the fixed interval corresponding to an uncorrelated status. The correlation factor is compared to a correlation threshold for a specified material and sets of data having correlation factors greater than the correlation threshold are identified.
