Abstract: A computer-implemented process determines, based on bearing fault frequencies, optimum values for the maximum frequency (Fmax) and the number of lines of resolution (Nlines) to be used in collecting machine vibration data so as to adequately distinguish between spectral peaks for identifying faults in machine bearings. The process can be extended to any other types of fault frequencies that a machine may exhibit, such as motor fault frequencies, pump/fan fault frequencies, and gear mesh fault frequencies. Embodiments of the process also ensure that the time needed to acquire the waveform is optimized. This is particularly useful when collecting data using portable vibration monitoring devices.

Abstract: Methods, systems, apparatus, and tangible non-transitory carrier media encoded with one or more computer programs that can determine the path or route most likely navigated by a mobile target are described. In accordance with particular embodiments, the most likely path or route is determined based on path-based scoring of position estimates obtained from different types of complementary locationing signal sources. Instead of fusing the position data derived from the different types of signal sources, these particular embodiments determine the most likely path navigated by the mobile target based on an independent aggregation of the position estimates derived from complementary signals of different source types.

Abstract: The invention provides apparatus for spray coating of substrates using a rotary bell cup atomizer equipped with an air-driven main turbine and a supply of pressurized primary shaping air conveyed through primary shaping air channels and nozzles for controlling the shape of the atomized spray pattern exiting the bell cup edge, the apparatus further including an auxiliary, independently air-driven turbine equipped with a rotatable vortex generator, and including a separate air supply of secondary shaping air for supplying secondary shaping air through secondary air channels and nozzles to further control the shape of the atomized spray pattern exiting the bell cup, which secondary shaping air, on passing through the vortex generator, produces a curtain of shaping air in a vortex-like pattern, which, in conjunction with and mixing with the primary shaping air from the primary air nozzles, produces improved pattern control, transfer efficiency and quality of coating on the substrate.

Abstract: Disparate live output stream manifests are generated based on user selection. When current media programming content in an existing first disparate live media output stream is streamed on a media player, one or more processors determine a set of alternate live input streams and/or a pre-encoded media assets, and associated alternate live media output manifests and/or pre-encoded media asset manifests, respectively, based on one or more parameters and metadata associated with the existing first disparate live media output stream. Based on an indicator in an existing first disparate live media output stream manifest, alternate content options are transmitted to the media player. A response is received corresponding to a selection of an alternate live input stream and/or a pre-encoded media asset, and an alternate live input stream manifest and/or pre-encoded media asset manifest is inserted into the existing first disparate live media output stream manifest as next programming media content.

Abstract: Techniques for implementing a non-relational database that makes efficient use of collections within the database. For one or more collections, two or more sub-collections can be created for storing documents. Each collection can be configured as a single partition entity or a partitioned entity within the database. Each sub-collection is identified by a sub-collection identifier. If the collection is configured as a partitioned entity, then a partition key can be determined for documents to be accessed in the collection. The partition key can be extended with the sub-collection ID to form a compound property (sub-collection ID, partition key) that determines placements of the respective documents in the identified sub-collection across partitions of the collection. If the collection is configured as a single partition entity, then a field for the partition key is ignored and the respective documents are placed in the identified sub-collection within the single partition of the collection.

Abstract: A 3-level T-type neutral point clamped (NPC) inverter/rectifier is disclosed in which neutral point clamping is dynamically enabled/disabled responsive to load, e.g. enabled at low load for operation in a first mode as a 3-level inverter/rectifier and disabled at high/peak load for operation in a second mode as a 2-level inverter/rectifier. When the neutral clamping leg is enabled only under low load and low current, middle switches S2 and S3 can be smaller, lower cost devices with a lower current rating. Si, SiC, GaN and hybrid implementations provide options to optimize efficiency for specific load ratios and applications. For reduced switching losses and enhanced performance of inverters based on Si-IGBT power switches, a hybrid implementation of the dual-mode T-type NPC inverter is proposed, wherein switches S1 and S4 comprise Si-IGBTs and switches S2 and S3 of the neutral clamping leg comprise GaN HEMTs. Applications include electric vehicle traction inverters.

The opportunity to upload the file may, by one approach, presume using a file format that comprises a non-standard file format for the particular physical medical-services LINAC.

Abstract: Described embodiments provide systems and methods of managing storage of data of a user across storage service providers. A storage service may receive a request to store data by a user. The storage service may communicate with storage service providers and may maintain storage vectors for each storage service provider. The storage service may identify a policy for the user. The policy may specify usage of the storage service providers based on a user profile. The storage service may determine, based on the policy, storage service providers to use to store the data of the user. The storage service may store a first portion of the data to a first storage vector of a first storage service provider. The storage service may store a second portion of the data to one of a second storage vector of a second storage service provider or a storage of the storage service.

Abstract: Methods, systems, computer-readable media, and apparatuses for parsing a user interface (UI) product to obtain a UI element provided therein, the UI product prepared in a first language. A UI element is replaced with a converted UI element, in which the converted UI element approximates a translation of the UI element into a second language different from the first language. After replacement of the UI element, a detection is made as to whether a UI issue exists. When a UI issue is detected, the converted UI element is modified so that translation of the UI product into the second language does not include the detected UI issue. The UI element is provided in a language different from the first language via the UI product based on the converted UI element.

The data management system may be able to gain operational advantages by performing load balancing across the multiple data paths.

Abstract: A static timing analysis system for finding timing violations in a digital circuit design prior to circuit fabrication, and associated methods, use infinite-depth path-based analysis (IPBA) to achieve reduced pessimism as opposed to systems or methods employing only graph-based analysis (GBA), but with greatly reduced compute time requirements, or greater logic path coverage, versus systems or methods employing conventional or exhaustive path-based analysis. IPBA achieves the improved coverage or compute time results by slotting nodes of a circuit design graph into stages, propagating phases stage-by-stage for all paths in parallel, and merging phases wherever possible during the analysis.
