  • Publication number: 20200240685
    Abstract: Embodiments of the present disclosure are directed toward purge units of vapor compression systems, and methods of control thereof, that improve efficiency by selectively activating and deactivating the purge unit in response to one or more conditions to, for example, enable refrigerant-to-air ratios within the purge unit within certain industry standards while still minimizing the durations of the purge cycles. For example, in certain embodiments, these conditions may include conditions within the chiller condenser, time since last purge activation, time since last venting of non-condensables, and combinations thereof.

  • Publication number: 20200117444
    Abstract: Methods and apparatus, including computer program products, implementing and using techniques for identifying program code changes causing a changed visual appearance of a graphical user interface of a computer application. A code change is received for the computer application in a build system. The code change results in a changed computer application. The changed computer application is run and screenshots of the visual appearance of the graphical user interface are captured and saved during the run. Differences between the saved screenshots are detected to identify changes in the visual appearance of the graphical user interface. The identified changes in the visual appearance are correlated with a particular section of program code causing the changes in the visual appearance.

  • Patent number: 10594850
    Abstract: A non-transitory computer-readable storage medium, a method, and a system for receiving display capabilities of a secondary vehicular display, determining metadata to display based on the display capabilities of the secondary vehicular display, formatting the displayable metadata, and transmitting the displayable metadata to the secondary vehicular display. The metadata is determined by receiving a data set from producer, comparing the data set against the display capabilities, and formatting the resultant data from the comparing as metadata.

  • Publication number: 20200011648
    Abstract: A tool, such as a tape measure, including a spring-based retraction system is shown. Various spring-based retraction system embodiments are configured to decrease the size occupied by the spring within the tape measure housing, which consequently reduces tape measure housing size providing a more compact tape measure. Various spring-based retraction system embodiments are configured to control retraction of the tape measure in a manner that reduces whip or otherwise controls tape blade retraction. Some retraction system embodiments utilize a reduction gear train, and others utilize a compression spring and a transmission system that converts rotational movement of the tape reel to axial movement, which compresses the spring.

  • Publication number: 20190359899
    Abstract: Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any “pitch” generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.

  • Publication number: 20190163635
    Abstract: Embodiments are provided for deferring allocation of storage for segments. The method includes receiving, at a first moment in time, a request to allocate a first segment within a memory. Information corresponding to the first segment is stored in a first entry in a hash table, and memory is allocated for the first segment. Information about the first segment is returned to an entity that requested the allocation of the first segment, where the first segment is not allocated auxiliary storage until predefined criteria are satisfied. At a second moment in time, upon receiving an indication to deallocate the first segment, memory corresponding to the first segment is deallocated, where the first segment is never allocated auxiliary storage and the first entry in the hash table is deleted.
