Abstract: A method for providing a self-reliant secondary network of communication nodes using resources associated with a primary network defining sector beams using corresponding resources including respective SSBs includes performing a beam search with respect to the sector beams, performing beam detection to detect neighboring beams among the sector beams, and performing geospatial beam selection to define a selected set of SSBs of respective ones of the sector beams as being geospatial white space unlikely to interfere with the primary network when utilized by the communication nodes in the secondary network. The method may further include performing power control with respect to the selected set of SSBs, and applying medium access control protocols to enable the secondary network to use the selected set of SSBs of the primary network.

Abstract: A system of networked sensors designed to predict the onset of chronic obstructive pulmonary disease (COPD) symptoms is disclosed. The system is worn by an individual and the sensors collect data correlated with COPD symptoms. The collected sensor data is transmitted from the device to the user's mobile device for analysis. The results of the analysis may be forwarded to a health care provider.

Abstract: A smart multi-modal telehealth IoT system for respiratory analysis. Such a system includes a body area sensor network comprised of meshed wireless sensor nodes and advanced machine learning techniques. The system may be used to remotely diagnose a user's respiratory illness and monitor their health.

Abstract: A wearable garment with sensors attached to obtain physiological data. The sensors are incorporated to form a body area sensor network to obtain the data. This provides patients with improved health monitoring by aggregating multiple interconnected nodes on a human body for sensorimotor measurements and provides patients with quantitative measurements of their progress. The data is obtained in a way that allows for the number of transmissions to be reduced thereby conserving the energy of the wearable devices. This is made possible by each sensor reducing the number of samples by eliminating predictable samples and configuring the sensors to pack the data efficiently. A neural network can determine whether a sample can be skipped or needs to be reported. A long short term memory architecture creates a waveform for a given snapshot of samples based on the previous samples regardless of whether these samples were reported or predicted.

Abstract: The least movement WSAN topology repair method features an algorithm utilized in wireless sensor actor networks (WSAN) to maintain and restore connectivity following network node failure. The method is distributed throughout the WSAN nodes and relies on nodes' local view about the network. The method uses Path discovery activities in the network to determine the structure of the network topology. Upon failure of a node, the method replaces the faulty node by selecting a neighbor node belonging to the smallest disjointed block. The method is applied further recursively in case the node replacing the faulty node gets disconnected from its children, i.e., neighbors within the block, while imposing no constraints to sustain the path length between any pair of nodes at pre-failure. In this manner, the method minimizes the number of nodes relocated while also reducing message travel distance and complexity.

Abstract: Techniques for inter-application communication and handling of I/O devices in an Integrated Modular Avionics (IMA) system enable the integration of multiple applications while maintaining strong spatial and temporal partitioning between application software modules or partitioned applications. The integration of application modules is simplified by abstracting the desired application interactions in a manner similar to device access. Such abstraction facilitates the integration of previously developed applications as well as new applications. The invention requires the least support from the operating system and minimizes the dependency of the integrated environment on application characteristics.

Abstract: A stand alone Redundancy Management System (RMS) provides a cost-effective solution for managing redundant computer-based systems in order to achieve ultra-high system reliability, safety, fault tolerance, and mission success rate. The RMS includes a Cross Channel Data Link (CCDL) module and a Fault Tolerant Executive (FE) module. The CCDL module provides data communication for all channels, while the FTE module performs system functions such as synchronization, data voting, fault and error detection, isolation and recovery. System fault tolerance is achieved by detecting and masking erroneous data through data voting, and system integrity is ensured by a dynamically reconfigurable architecture that is capable of excluding faulty nodes from the system and re-admitting healthy nodes back into the system.
