Abstract: Techniques for synthetic data generation in computer-based reasoning systems are discussed and include receiving a request for generation of synthetic data based on a set of training data cases. One or more focal training data cases are determined. For undetermined features (either all of them or those that are not subject to conditions), a value for the feature is determined based on the focal cases. In some embodiments, the generated synthetic data may be checked for similarity against the training data, and if similarity conditions are met, it may be modified (e.g., resampled), removed, and/or replaced.

A graphic interface correlating to an event requested by users is communicated for display on a computer device of each user. Users are depicted with respective user icons on the graphic interface wherein they can choose to join groups of other users, communicate with individual other users, and view streaming video generated by other users using a drag and drop of their respective user icon to make such choices.

Abstract: An identity verification device for verification of a digital credential includes a user device communication interface for operative communication with a user device associated with a human user. The user device communication interface is operative to receive from the user device the digital credential of the human user stored locally on the user device. The device also includes a relying party communication interface operative to send a request to an intermediary credential service platform for verification of the digital credential presented by the user device, and to receive verification of the digital credential from the platform after application of an issuing authority credentialing standard to the digital credential. The device further includes a verification indicator operative to provide an indication of verification status of the digital credential to the relying party associated with the identity verification device.

Abstract: Verification of digital identities with a non-repudiable proof of identity maintained in a verification log. The verification log may be generated by a platform for verification of a digital identity of a human user in response a request for verification of a human user's identity from a relying party. Such verification may be performed via online transactions or via an identity verification device. The non-repudiable proof of identity may include records in the verification audit log that may be non-reversible. As such, anonymized records may be maintained that demonstrate proof of identity verification without providing sensitive details. The verification log may be accessible by relying parties and/or end users to provide a record of verifications.

Abstract: A platform for verification of a digital identity of a human user in response a request for verification of a human user's identity from a relying party. The platform may include a digital identity credentialling database storing a plurality of issuing authority credentialling standards that define verification of a digital identity issued by an issuing authority. The platform may receive from a user device a user digital identity stored locally at the user device. The platform may include a verification engine operative to access the digital identity credentialling database and retrieve an issuing authority credentialling standard associated with the user digital identity and apply the issuing authority credentialling standard to the user digital identity to perform a verification operation on the user digital identity. The relying party communication interface returns an outcome of the verification operation to the relying party.

Abstract: A method for predicting an estimated wait time includes receiving a pending support request from a user. The pending support request is associated with a plurality of high-level features that include a number of active support agents, a number of available support agents, and a queue depth. The method also includes predicting an estimated wait time for the user of the pending support request using a wait time predictor model configured to receive the plurality of high-level features as feature inputs. The wait time predictor model is trained on a corpus of training support requests that include corresponding high-level features and a corresponding actual wait time. The method also includes providing the estimated wait time to the user that indicates an estimated duration of time until the pending support request is answered.

Abstract: A system for treating high temperature produced water includes an electrocoagulation unit, a membrane distillation unit in communication with the outlet of the electrocoagulation unit having a hydrophobic membrane with a feed side for receiving the produced water stream and a product side for receiving a deionized water stream. A heat recovery heat exchanger is in communication with the membrane distillation unit for receiving two streams, one from each side of the hydrophobic membrane, such that heat is exchanged between the two streams. A line leaving the heat exchanger returns a heated stream from the heat exchanger to a location in a line upstream of the membrane distillation unit. A brine tank in communication with the membrane distillation unit receives a portion of a stream from the membrane product side and contains a concentrated brine solution containing the portion of the stream from the membrane product side and sodium chloride.

Abstract: The present invention provides a reliable communication protocol that provides multicasting of digital messages on an interprocessor link coupling together a plurality of processors of a load control system. Preferably, the load control system includes a plurality of sub-systems, with a number of the processors in each sub-system. The processors are each characterized by a unique individual address, while all of the processors of a single sub-system are characterized by an identical multicast address. The processors re-transmit digital messages on the communication link if a target address of the digital message is equal to the multicast address. The processors determine if acknowledgement messages are received from each of the processors from which acknowledgement messages were expected during a predetermined amount of time after transmitting an initial digital message, and transmit a retry message in response to determining that the acknowledgement messages were not received.
