Abstract: An apparatus configured to provide portioned instances of a compressible material includes a channel assembly, a gas source, a cutting assembly, and a discharge assembly. The channel assembly holds a bulk instance of the material extending through upper and lower channels of a continuous channel. The gas source supplies gas to compress the bulk instance. The cutting assembly moves in relation to the channel assembly to isolate the upper and lower channels, severing upper and lower material portions of the bulk instance. The discharge assembly directs gas to impinge on a lower face of the cutting assembly to discharge the lower material portion as a portioned instance. The channel assembly may be moveable, where operation of the gas source, cutting assembly, and/or discharge assembly are based on moving the channel assembly between various positions. The gas supply may be controlled based on a determined property of the portioned instance.

Abstract: Safety valves and methods of operating the same. An example safety valve includes a first piston disposed within a safety valve body. The first piston forms a first seal with the interior of the safety valve body. The first piston, the interior of the safety valve body, and the first seal define two chambers within the safety valve separated by the first seal. The first chamber is a control line pressure chamber disposed uphole of the first seal, and the second chamber is a fluid compression chamber disposed downhole of the first seal. The control line pressure chamber is pressurized to translate the first piston downhole in an axial direction. A second seal is formed with an annulus outside of and adjacent to the safety valve. A biasing mechanism translates the second piston uphole in the axial direction. A fluid volume chamber is fluidically connected to the fluid compression chamber.

Abstract: Provided is a data protection system that operates to shield private data from detection or communication over a network. In an embodiment, the system includes a shielding device that, when active, provides a shielding output that shields, e.g., obscures, detection of private data by sensors of smart devices. The shielding may be selectively activated such that active sensors of the smart devices may operate or detect environmental events normally during times outside of the shielding. A data protection tool of the system may remove or shield private data generated by a user device, e.g., by modifying captured image data.

Abstract: An objective of an endoscope can be evaluated by collecting a series of differently focused images and digitally stitching them together to obtain a final image for the endoscope that can be then evaluated. Movable optics and/or a camera can be used to collect the series of differently focused images. Image processing algorithms can be used to evaluate the collected images in terms of image sharpness and identify the areas at which each image is in relatively good focus. Once the areas of good focus are identified, the image processing algorithms can extract the areas of good focus. The digital stitching algorithms can be used to assemble the extracted areas of good focus to form a final image where most of the target scene should be in focus. The final image is then reviewed to determine the acceptability of the objective.

Abstract: Disclosed are a system, apparatus and techniques for evaluating a dataset to confirm that the data in the dataset satisfies a data quality metric. A machine learning engine or the like may evaluate text strings within the dataset may be of arbitrary length and encoded according to an encoding standard. Data vectors of a preset length may be generated from the evaluated text strings using various techniques. Each data vector may be representative of the content of the text string and a category may be assigned to the respective data vector. The category assigned to each data vectors may be evaluated with respect to other data vectors in the dataset to determine compliance with a quality metric. In the case that a number of data vectors fail to meet a predetermined quality metric, an alert may be generated to mitigate any system errors that may result from unsatisfactory data quality.

Abstract: Systems and methods of the present disclosure enable intelligent dynamic caching of data by accessing an activity history of historical electronic activity data entries associated with a user account, and utilizing a trained entity relevancy machine learning model to predict a degree of relevance of each entity associated with the historical electronic activity data entries in the activity history based at least in part on model parameters and activity attributes of each electronic activity data entry. A set of relevant entities are determined based at least in part on the degree of relevance of each entity. Pre-cached entities are identified based on pre-cached entity data records cached on the user device, and un-cached relevant entities from the set of relevant entities are identified based on the pre-cached entities. The cache on the user device is updated to cache the un-cached entity data records associated with the un-cached relevant entities.

Abstract: Rate of rancid flavor development in oil-based sauces and dressings can be slowed down by addition of a mixture containing sequestering agents for dissolved oxygen and heavy metal ions that are derived from vinegar and fruit juices. The types and proportions of the components of the mixture are chosen to promote a balance of flavor and color neutrality and adequacy of sequestering both heavy metal ions and dissolved oxygen. The mixture is effective in retarding development of rancid flavor moieties of hydroperoxides and hexanal, similar to a commonly-used chemical sequestrant, ethylene diamine tetra acetate (EDTA).

Abstract: Disclosed herein are system, method, and computer program product embodiments for automatically failing over all services operating on a primary region to a secondary region upon detection or notification of a fault in the primary region. When a fault exists on the primary region, the method traverses each cluster containing services operating on the primary region and prepares an input file including a list of service names identifying each service operating on the primary region. Referencing the input file, the method fails over each service from the primary region to the secondary region by modifying a service weight corresponding to each service. This failover process of services may be done simultaneously with failing over any databases corresponding to the failed-over services from the primary region to the secondary region. The method may also introduce a sleep time after modifying each service weight to avoid any potential throttling issues.
