Abstract: An online document system provides a recommendation for one or more features within the online document system to an entity. The online document system accesses a set of feature training data to train a machine learning model. The set of feature training data may describe characteristics of entities associated with the online document system and historical activity associated with the entities' usage of the online document system's features. The machine learning model may be configured to identify a feature to recommend to an entity based on the entity's characteristics and history of using other features within the online document system. For example, data representing the entity's user accounts and use of an electronic signature feature is used by the machine learning model to identify a document authentication feature to recommend to the entity. The online document system may then provide the identified feature in a recommendation to the entity.

Abstract: An improved system for handling delicate linear media and in particular to a method and apparatus for winding delicate linear media such as superconducting wire or tape or optical fibers onto a spool or former. A combination of direct closed loop control and media routing design facilitates the handling of the delicate media without causing damage. The axial tension in the linear media may be closely controlled during winding by means of feedback control loop using tension measurements to control the rotation speeds of the wind-from and wind-to spools. Further, during winding, the delicate linear media is only exposed to large radius bends with no reverse bending. Finally, output devices and features, commercial or otherwise, made possible by delicate linear media handling are revealed. This includes advanced SC devices and features.

A set of features associated with the road segment can be determined based at least in part on data captured by one or more sensors of a vehicle. A level of similarity between the road segment and each of a set of road segment types can be determined by comparing the set of features to features associated with each of the set of road segment types. The road segment can be classified as a road segment type based on the level of similarity. Scenario information associated with the road segment can be determined based on the classified road segment type.

The method comprises training an intermediate artificial intelligence by providing markered digital images of one or more skin parts to the intermediate artificial intelligence engine as a source training data set and providing markerless digital images of the one or more skin parts to the intermediate artificial intelligence engine as a target training data set. The intermediate artificial intelligence engine removes markers from markered digital images of the face of a first person to create corresponding synthetic markerless digital images of the face of the first person. The markered digital images of the face of the first person are converted into a mapping. The output training data set comprises the synthetic markerless digital images of the face of the first person and the mapping.

Abstract: An online document system manages access to features within the online document system. The online document system may receive and fulfill a request from a first entity to sponsor a feature for a second entity. The online document system may determine an access policy to restrict access to the sponsored feature. For example, the access policy may include a requirement that the second entity only use the sponsored feature with the first entity. The first entity may provide a second access policy to the online document system to enforce. If the second entity satisfies requirements of the access policies, the online document system may then provide access to the second entity to use the sponsored feature.

Abstract: A method, a computer program product, and a system are provided that handles host requests on a hardware security module (HSM). The method includes selecting a domain with a longest wait time with a host request for the HSM and selecting an oldest host request requested by the domain. The method also includes determining a hardware engine type required to process the oldest host request and determining a saturation level of the hardware engine type exceeds a saturation threshold. The method further includes selecting a second host request requested by the domain that uses a different hardware engine type based on the saturation level exceeding the saturation threshold and processing the second host request using the different hardware engine type of the HSM. The method further includes selecting unprocessed host requests of the domains to continuously provide efficient selection of those host requests to the HSM.

Abstract: A demand-based load balancing function may be provided by one or more drive controllers that takes advantage of the affinity laws to linearize the control of the variable of interest (e.g., flow, pressure, etc.). Each drive controller may be set up by the user simply inputting a few values into the drive controller. Based on the inputs, the drive controllers may interpolate control points using an assumed linear relationship between the variable to be controlled (e.g., pressure) and the current driven to the pump. Feedback data from the system may be used to continually update the drive controllers so as to potentially allow them to better balance power usage to each pump.
