  • Patent number: 11907765
    Abstract: Fog computing systems are provided comprising edge-nodes and middle-nodes between edge-nodes and cloud-node. These nodes form a hierarchical structure with each cloud, middle node having children nodes, and each middle, edge node having a parent-node. Each edge-node receives data from sensors, assigns reception-timestamp to each data indicating when data has been received to produce series of timestamp-ordered data, trains local model through machine-learning based on said series of timestamp-ordered data, and sends said series to parent-node of the edge-node. Each middle-node collects series of timestamp-ordered data from children nodes of the middle-node, trains supra-local model through machine-learning based on said collected series of timestamp-ordered data, and sends said collected series to parent-node of the middle-node. Parent-children structures, edge-nodes and middle-nodes for such fog computing systems are also provided.

  • Patent number: 11491263
    Abstract: The present invention refers to a method for the synthesis of a biodegradable calcium release material that shows controlled ion release properties for tissue engineering, biomaterials containing the calcium particles as well as the calcium particles obtainable therefrom. By varying the treatment temperature of the described method, the calcium material shows different calcium release profiles. Contrary to a specific chemical composition such as CaCO3 which is associated to a specific calcium release profile, the present invention allows a manifold of compositions, with a manifold of calcium release profiles, all starting from a single specific chemical composition calcium precursor. Therefore, the invention also relates to the use of the controllable release, calcium material in tissue regeneration such as wound healing processes.

  • Patent number: 11436048
    Abstract: Hardware acceleration of task dependency management in parallel computing, wherein solutions are proposed for hardware-based dependency management to support nested tasks, resolve system deadlocks as a result of memory full conditions in the dedicated hardware memory and synergetic operation of software runtime and hardware acceleration to solve otherwise unsolvable deadlocks when nested tasks are processed. Buffered asynchronous communication of larger data exchange are introduced, requiring less support from multi-core processor elements as opposed to standard access through the multi-core processor elements. A hardware acceleration processor may be implemented in the same silicon die as the multi-core processor for achieving gains in performance, fabrication cost reduction and energy consumption saving during operation.
