  • Patent number: 11033006
    Abstract: An annular fluid-filled sample chamber is used to provide observation of unbounded motion of objects in the fluid. Rotation of the sample chamber is under automatic control to compensate for azimuthal motion of the object, thereby keeping the object in a fixed field of view of an optical observation system. Further motion control can be provided in the radial and focus directions, which can be used to provide full 3D tracking of objects as they move in the fluid. An important application of this work is to observation and tracking of objects that move up or down in the fluid with respect to gravity.

  • Patent number: 11029289
    Abstract: Disclosed is an apparatus and method for TFM post-processing of a FMC or HMC matrix acquired with an ultrasonic array probe. Post-processing is performed by calculating TFM beam forming amplitudes using round-trip delays to a focal point lying at depth d on a line at angle ? within the test object. Based on the beam forming amplitudes over a range of values of d within the imaging volume, a calculated A-scan is derived, which is equivalent to the response A-scan produced in conventional phased array imaging, but has the advantage of being focused at all points along the line. By post-calculation of calculated A-scans over a range of angles ? within the imaging volume, an imaging method is derived which is readily adapted to existing codes based on conventional A-scan imaging.

  • Patent number: 11022480
    Abstract: A method for checking the functional ability of an FMCW-based fill-level measuring device, which serves for measuring the fill level of a fill substance located in a container, as well as to a fill-level measuring device suitable for performing this method. For checking the functional ability, a microwave signal is produced, whose frequency change differs from the frequency change of the measurement signal used during regular measurement operation. By comparing the frequency of the difference signal resulting from the microwave signal with a predetermined reference frequency, it is ascertained, whether the fill-level measuring device is functionally able. Thus, the fill-level measuring device detects, independently, whether it is functionally able, or whether an error is present, caused principally by device-internal disturbance signals. This offers, especially, a clear advantage as regards meeting safety standards for the field device.

  • Patent number: 11009489
    Abstract: In gas chromatography (GC), a sample is introduced into a flow of carrier gas and the mixture is driven through a heated GC column to acquire chromatographic data from the sample. During this time, the column is heated from an initial temperature to a final temperature. Subsequently, the column is cooled according to a cooling program. The cooling program may include a first cooling ramp, a subsequent isothermal hold, and a subsequent second cooling ramp. Alternatively, while the column is cooled down the flow of carrier gas through the column may be slowed down or ceased for a period of time, after which the flow of carrier gas through the column may be resumed at the original flow rate in preparation for processing another sample. Controlling column temperature and/or flow in this manner may be effective for reducing column bleed carryover and/or the effects thereof.
