Abstract: There are provided systems and methods for monitoring a property using a system of sensor units in one or more premises on the property that can interface with respective utilities entering the premises or being generated by appliances on the premises with a minimal of effort and without requiring modification of the utility's equipment or the appliance. The systems and methods are connectable to a cloud-based monitoring, analytics and notification system via a long range network connection directly from one or more of the sensor units. The system of sensors can also incorporate primary and secondary units with at least one primary unit capable of communicating directly to the cloud-based system/server via a long-range connection with the secondary units sending data to the cloud via the primary unit by communicating at the property via a short-range communication connection.

Abstract: An integrated sensor and service port for HVAC (heating, ventilating, and air conditioning) equipment or an HVAC system.

Abstract: Apparatus, systems, and methods for bonding one element of an electrochemical cell or cell stack to another wherein a sealing grove with a complex cross-sectional shape receives and retains a bead of adhesive prior to being assembled. The complex cross-sectional shape has a raised portion sized to receive and retain the bead of adhesive, and at least one depressed portion to receive adhesive displaced from the raised portion during assembly. Embodiments of the invention incorporate raised portions with straight, beveled, curved, and rough surfaces to increase the strength of the bond between the respective elements.
