  • Patent number: 10337672
    Abstract: In processes and systems utilizing a compressor to fill a vessel with gas, for example, in the filling of the fuel tank of a vehicle that operates on compressed natural gas (CNG), a number of advantages are realized by establishing independent control over the flow rate of gas discharged from the compressor, such as on the basis of the compressor discharge pressure, utilizing feedback from one or more gas pressure sensors. In representative embodiments, a detected or actual measured compressor discharge pressure can serve as a process variable, in a feedback control loop for regulating the output of the compressor.
    Type: Grant

  • Publication number: 20130022502
    Abstract: Systems and methods for performing measurements of one or more materials are provided. One system is configured to transfer one or more materials to an imaging volume of a measurement device from one or more storage vessels. Another system is configured to image one or more materials in an imaging volume of a measurement device. An additional system is configured to substantially immobilize one or more materials in an imaging volume of a measurement device. A further system is configured to transfer one or more materials to an imaging volume of a measurement device from one or more storage vessels, to image the one or more materials in the imaging volume, to substantially immobilize the one or more materials in the imaging volume, or some combination thereof.

  • Patent number: 8060316
    Abstract: Methods, data structures, and systems for classifying particles are provided. In particular, the methods and systems are configured to acquire a first set of data corresponding to measurable parameters of a microparticle and identify a location of a look-up table to which the first set of data corresponds, wherein the look-up table is framed by values associated with at least one of the measurable parameters. Furthermore, the methods and systems are configured to determine whether the first set of data fits one or more predefined algorithms respectively indicative of a different microparticle classification associated with the identified location of the look-up table. The methods and systems are further configured to classifying the microparticle within at least one predefined categorization based upon the determination of whether the first set of data fits the one or more predefined algorithms.
