Abstract: Systems, devices and methods for managing mobile assets at a worksite. A system computer creates a geofence relating to the geolocation of a first communication device disposed in a first mobile asset, the data points of the geofence periodically updated according to the geolocation of the first communication device such that changes in the geolocation of the first communication device are proportionally reflected in the updated geolocation of the datapoints of the geofence. The cycle time of a second communication device disposed in a second mobile asset can be determined by determining the amount of time lapsed after the second communication device triggers the geofence. Various triggering events are described. Various shapes of the geofence are described to avoid unintended triggers of the geofence by assets, including polygonal shapes.

Abstract: A method of analyzing a composite structure for damage tolerance. The method includes obtaining a structural configuration and determining at least one metric of interest for the structural configuration. A dent depth meta-model is developed based on the structural configuration, the at least one metric of interest, and information obtained from a machine learning algorithm. The at least one metric of interest provides a constraint for the dent depth meta-model and the machine learning algorithm is trained based on a historical physical test dataset of a plurality of composite components. The dent depth meta-model is utilized to estimate an impact energy to establish a threshold dent depth in the structural configuration. A computer-based simulation is performed with the structural configuration utilizing the impact energy from the dent depth meta-model. At least one design value is determined for the structural configuration based on output data generated from the computer-based simulation.

Abstract: A countercurrent heat recovery ventilation system includes an air module assembly and heat exchanger assembly. Air module assembly made from front and back panels connected by two side panels, base plate fixed with the side panels and placed parallel between side panels and a double side radial impeller with a shaft, an electric drive form two hydraulically isolated flow canals with inlet and outlet openings. The heat exchanger assembly comprises a heat-exchanger that could be done as changeable flow side heat-exchanger made as folded corrugated fins or plates, thus each of the both flow passages split in separate flow channels. Every other channel is sealed to flow from flow same direction forcing the flow to be in opposite direction in all adjacent cannels. This forms two hydraulically isolated flow passages with intake and outtake openings connected respectively with outlet and inlet openings of the air blower assembly.

Abstract: Certain example embodiments relate to techniques for investigating event streams in complex event processing (CEP) environments. Input events from one or more input event streams and query registration-related events from a registration event stream are received. Query registration-related events are associated with actions taken with respect to queries performed on the input event stream(s). Event-based profiles are developed by subjecting the received input events to a profiling CEP engine. Event-based profiles include data mining related and/or statistical characteristics for each input event stream. Query-based profiles are developed by subjecting the received query registration-related events to the CEP engine. Query-based profiles include data indicative of how relevant the queries performed on the input event stream(s) are and/or how those queries are relevant to the input event stream(s) on which they are performed.

An error handler is controlled to at least: receive, via an event bus, events from external input event sources; receive, via the event bus, error events from an application configured to process events received from the event bus, and to provide to the event bus results obtained from processing received events, and error events corresponding to errors detected at its input and/or processing layer(s); generate, for a given error, an error analysis event and an error impact event by executing a CEP query on at least a corresponding received error event; and provide to the event bus generated error analysis events and generated error impact events. Error analysis events describe for administrators detailed information analyzing corresponding errors. Error impact events describe for business users impacts corresponding errors have for their business user applications.

Abstract: An electromagnetic moving system comprises a stator, a moving body and a controller. The stator comprises a circuit board with two layers of electrically connected coil windings spaced apart in a series way and made as spirals with center and peripheral points. The spirals of one layer are shifted in respect to the spirals of the adjacent layer along the line connecting the center points thus the center points of the spirals of one layer in transparent view are located between two nearest spirals of the adjacent layer. Each of the spirals of one layer in transparent view at least partially overlaps two nearest spirals of the adjacent layer. The moving body is comprised of one permanent magnet such as to cause interaction with the stator when it is powered, thus creating a force tending to propel the moving body along the line connecting said center points.

Abstract: Pool balls falling into the pockets of a pool table during a game are fed through primary conduits below the table and then passed one at a time through the field of view of a camera which identifies the color and/or markings on the ball and forwards each ball through an appropriate secondary conduit to a rack located in a receiving position adjacent one end of the table. The rack is mounted on a carriage pivotally secured to the table at one end thereof so that, when the rack is full, the carriage can be pivoted from the receiving position to a discharge position over the table so that the balls can then be discharged from the rack in the correct formation on the table. Releasable retainers are provided to retain the balls in the rack during the pivoting movement and until the rack is in position over the table.
