Abstract: A high-voltage protection module for a metrology device includes a metal-oxide varistor (MOV) coupled across a mains power line, a resistor electrically coupled to the MOV in series with the MOV, and a fuse electrically coupled to the MOV and the resistor in series, the resistor being located between the fuse and the MOV. The fuse opens upon an overvoltage event disengaging alternating current (AC) power from the mains power line to the metrology device.

Abstract: Techniques for network reliability include, in response to determining, at a first node in a mesh network and based on a first combined accumulated message success rate, that a search for a different parent node should be performed: performing one or more communication operations to discover a plurality of nearby nodes; computing respective second combined accumulated message success rates associated with respective nodes of the plurality of nearby nodes; and based on the respective second combined accumulated message success rates, selecting a new parent node from the plurality of nearby nodes or maintaining an established parent node. The first combined accumulated message success rate is based on an accumulated uplink message success rate, a first offset value associated with the accumulated uplink message success rate, an accumulated downlink message success rate, and a second offset value associated with the accumulated downlink message success rate.

Abstract: One embodiment of the present invention sets forth techniques for processing packets transmitted within a network in accordance with a network protocol. The techniques include receiving, by a network device in a mesh network, a type-length-value (TLV) element; determining, by the network device based on both a first type identified in a type field of the TLV element and a value in at least one sub-field of a value field of the TLV element, an expected length of the value field of the TLV element; and processing, by the network device, the value field up to the expected length.

Abstract: An electricity meter and electricity system or grid that is hardened against attack vectors is described, and provided in part by automated multiple-factor authentication over multiple communication networks. In an example, a utility company may control an advanced metering infrastructure (AMI) network to provide internal communications. Metering devices may utilize customer's Wi-Fi to gain access to the internet, allowing electricity consumption data to be transmitted over the internet. Multiple authentication factors are used to prevent a bad actor from impersonating the metering device or cloud server. In an example, each metering device determines a secret, and sends the secret over the AMI network to a utility company server, and which relays the secret to the cloud server. The cloud server uses the secret to establish trust with metering devices. Additionally, the metering devices and the cloud server have signed certificates, which are used in additional authentication processes.

Abstract: One embodiment of the present invention sets forth a technique for evaluating connections between nodes in a mesh network. The technique includes determining, at a first node, one or more first accumulated message success rates associated with transmitting messages from the first node to a target destination within the mesh network via an established parent node and with receiving messages from the target destination via the established parent node; determining, based on the one or more first accumulated message success rates, that a search for a different parent node should be performed; identifying a plurality of potential parent nodes; computing, for each potential parent node, one or more second accumulated message success rates associated with transmitting messages from the first node to a target destination within the mesh network via the potential parent node and with receiving messages from the target destination via the potential parent node; and based on the second accumulated message success rates, selecting a new parent node from the plurality of potential parent nodes or maintaining the established parent node.

Abstract: Device(s) and techniques determine if a gas regulator supplying gas at a regulated pressure to a gas meter (e.g., the gas meter of a house or business) within a gas distribution system has one or more lock-up failure events or venting events, wherein gas is vented to the atmosphere. In an example, a sensor obtains information indicating a relative position of a stop stem of a gas regulator and a diaphragm pin of the gas regulator. As pressure increases within the regulator, the diaphragm pin moves toward and/or touches the stop stem. The gas pressure increase may result from debris in the regulator that prevents a valve from fully closing. A signal may be sent from the regulator and/or associated gas meter. The signal may contain information based at least in part on data from the sensor, and which may indicate a lock-up failure event or a venting event by the gas regulator.

Abstract: Various embodiments disclosed herein provide techniques for managing encryption keys at nodes in a mesh network. In various embodiments, a method includes, while in a key failure detection time period associated with a first key, detecting, by a node in a mesh network, a decryption failure using the first key; in response to detecting the decryption failure using the first key, incrementing, by the node, a failure count for the first key; and in response to determining that the failure count is at least a threshold count and a key update time period has been entered, transmitting, by the node to a key management service, a request for an update to the first key.
