Abstract: A direct carbon fuel cell (DCFC) has a conductive mesh between an anode and a cathode of the DCFC. The conductive mesh is positioned at a specified distance from the anode. As the DCFC is operated, a carbon/carbonate fluid flows through the conductive mesh and though the porous anode. If the rate of carbon introduced into the DCFC is greater than the amount consumed, carbon will build up on the surface on the anode. Once the carbon build-up reaches the mesh, a conductive path will be created between the mesh and anode. A controller in contact with the conductive mesh measures the resistance between the conductive mesh and the anode and when the measured resistance falls to or below a defined set-point indicating a resistance when a conductive path between the anode and conductive mesh has formed, the controller can send a carbon build-up detected signal, and/or execute mitigation actions to reduce the amount of carbon delivered to the cell.

Abstract: A cybersecurity service protects endpoint devices from cybersecurity attacks. The cybersecurity service deploys cybersecurity attack feature vectors to agents in the field. The cybersecurity attack feature vectors are created in the cloud to efficiently describe observed groups of cybersecurity attacks. One method to assemble these is to generate clustering centroids for the observed groups. Each agent monitors its host according to the cybersecurity attack feature vectors. Each agent monitors its host's event behaviors and locally extracts an event behavior feature vector. The agent compares the cybersecurity attack feature vectors to the event behavior feature vector and, if similarity is determined, then the agent determines that the host's event behaviors are evidence of a cybersecurity attack. The agent may implement threat procedures, such as suspending/terminating the event behaviors and generating alerts.
