Abstract: The concepts described herein provide a method, apparatus, and system for controlling an inverter by modifying duty cycles of the PWM control signals in a manner that achieves a minimum duration between consecutive switching events in the inverter, which serves to reduce common mode current in the bearing(s) of an attached rotary electric machine. To minimize the effect of additional current and voltage ripple into the system, the minimum switching duration is defined in relation to a modulation index and geometric location near the sector boundaries of the respective inverter voltage space vector diagram.

Abstract: Methods and apparatus for enhancing communication and performance for a device backhauled by a wireline communication network. In one embodiment, the device comprises a small-cell or other wireless base station that is backhauled by a DOCSIS system within a managed HFC network, and the method and apparatus enable enhanced communication between the small cell/base station and the backhaul network so as to support “rate matching” between the device to mitigate packet overflow or other issues. In one implementation, enhanced cable modem (CM) and base station devices coordinate to inform the base station of the modulation order (and/or other parameters related to transmission of the data destined for the base station on the backhaul) so that the base station can selectively invoke utilization of higher-order modulation and/or coding schemes, as well as spatial multiplexing or beamforming.

Abstract: Network traffic is monitored over a period of time (e.g., network traffic of a corporate network). Based on the monitored network traffic: an abstract temporal graph of the network traffic is generated; graph-based node embeddings of the abstract temporal graph are learned; edge tabular embeddings for edges of the abstract temporal graph are learned; and hybrid embeddings are computed. The computed hybrid embeddings are based on the learned graph-based node embeddings for the abstract temporal graph and the learned edge tabular embedding for the edges of the abstract temporal graph. This process is then repeated over multiple time periods and temporal trajectories are computed using the computed hybrid embeddings for each time period. The temporal trajectories are then used for analysis of the network. For example, the temporal trajectories are used to identify anomalies for prevention of security breaches of the network.

Abstract: This disclosure relates to a privacy preserving machine learning platform. In one aspect, a method includes receiving, from a client device and by a computing system of multiple multi-party computation (MPC) systems, a first request for user group identifiers that identify user groups to which to add a user. The first request includes a model identifier for a centroid model, first user profile data for a user profile of the user, and a threshold distance. For each user group in a set of user groups corresponding to the model identifier, a centroid for the user group that is determined using a centroid model corresponding to the model identifier is identified. The computing system determines a user group result based at least on the first user profile data, the centroids, and the threshold distance. The user group result is indicative of user group(s) to which to add the user.

Abstract: Methods and systems for secure geolocation-based data access control include a server that captures a data access request from a remote device and determines whether the requestor geolocation corresponds to a non-restricted zone or a restricted zone. The server determines whether the requestor identity has permission to receive a full view or a masked view of data. The server retrieves data responsive to the data query and generates a response to the data access request, the response including a full view or a masked view of the retrieved data. When the generated response comprises a masked view, the server determines that the user of the remote device has requested a full view of the responsive data, authenticates the remote device using the requestor identity, and updates the generated response to comprise the full view of the retrieved data. The server device transmits the generated response to the remote device.

Abstract: A system, method and computer readable medium for dynamically determining location-based rules affecting item sales at POS registers for a particular location and for distributing the location-based rules to the POS registers is discussed. A location-based ruleset of rules regulating sales of items at an individual store is created and transmitted to the store along with a rule group to item map file that maps rules and warnings to individual store items. A rules engine at the store provides updated item sale rules and warnings to POS registers based on the location-based ruleset and rule group to item map file. Embodiments thus provide an improved system for updating POS registers at different store locations with location-based rules specific to the store location.

Upper and lower recovery sleeves are disposed about the mandrel and extend between the mandrel and respective upper and lower ends of the packing element. The upper and lower recovery sleeves each have a recovery profile embedded within the packing element. Upper and lower backup assemblies are movably disposed about the respective upper and lower recovery sleeves, adjacent to the respective upper and lower ends of the packing element. The packer assembly includes at least one release mechanism. When setting the packer assembly in a bore, the packing element is axially compressed between the upper and lower backup assemblies to contact the bore wall, and the upper and lower backup assemblies splay outwards. Upon release, the packing element and backup assemblies retract, thereby facilitating retrieval of the packer assembly from the bore.
