Abstract: Disclosed is a system and method for processing data using blockchain technology. The system includes a memory having programmable instructions stored thereon that, when executed by a processor, cause the system to: authenticate one or more sensors in anticipation of receiving component data; receive component data, upon successful authentication; store the component data locally or to a cloud-based server and/or calculate a root value for the component data; store or embed the root value with the stored component data; condense the component data and link the condensed component data to the stored component data via the root value. The system further includes instructions to log the condensed data, including the root value, to a ledger, and to identify a tag or transaction id corresponding to the logging event for subsequent retrieval of the condensed data using the tag or transaction id.

Abstract: Systems and methods to perform privacy-aware computer-vision-based human activity monitoring with real-time haptic feedback. The system and method described in this disclosure employing a registration process for consenting human subjects before their activities are monitored. The registration process involves the corroboration of human motion captured in different modalities, i.e., computer-vision-based via the programmable computer-vision-based motion sensor and accelerometer-based via the wearable device. The tracked human activities are assessed in real-time and upon detection of activities that violated predefined rules, haptic feedback is delivered in real-time to the tracked human subject via the wearable device worn by the caregiver.

Abstract: Systems and methods to perform privacy-aware computer-vision-based human activity monitoring with automatic registration are disclosed. To register for tracking, consenting human subjects wear beacons that emit a beacon signal. During a predefined timing window, beacon signals are detected and compared to a predefined signal-strength threshold and compared to the signal strength of other different beacon signals detected during the same timing window. At the end of the timing window, the strongest beacon signal above the threshold is selected for registration. The tracked human activities are assessed in real-time and upon detection of activities that violated predefined rules, feedback is delivered in real-time to the tracked human subject.

Abstract: A system and method automatically recognizes complex activities and gaze patterns. One particular application of the system and method is the recognition of the activities and gaze patterns of a nursing student who practices nursing skills during human patient simulations (HPS). Accordingly, the system and method provide a novel event-drive context model for complex human activity and gaze recognition. The system and method include the identification of all necessary context and the development of an ontology for HPS to recognize complex activities in HPS, the encoding of correctness rules for skills in HPS, automated identification of errors made by the student during a simulation session, and the development of personalized feedback based on the data collected during a session and the predefined correctness rules. The system and method also incorporates a marker-based mechanism that facilitates privacy-aware tracking wherein only a consented user will be monitored.

Abstract: A consistent time service that provides a method of maintaining deterministic clock-related operations for a group of replicas in a fault-tolerant distributed system. A consistent clock synchronization algorithm is utilized that yields a single consistent group clock for the replicas in the group, and does not require synchronization of the underlying physical hardware clocks. The consistent group clock ensures the determinism of the replicas in the group with respect to clock-related operations, is monotonically increasing, has bounded increment, skew and drift. The consistent time service provides benefits for active replication during normal operation, as well as passive replication and semi-active replication to ensure a consistent monotonically increasing clock when the primary replica fails and a backup replica takes over as the new primary replica.
