Abstract: A method and system are provided for remotely monitoring the open and close status of a garage door via the internet based on the internet of things concept and NFC (Near Field Communication) technology. The system includes a Door Monitoring & Controlling Device (DMCD) and a web based Advanced Door Management System. The DMCD contains a NFC module, and one or more NFC close/open status tags which work together to monitor the status of the garage door. The NFC tag in this system not only provides status signal but also provides network configure data that eliminates the need to make standalone device configurable for network connectability. The use of NFC technology here will reduce manufacturing cost significantly, and make the configuration easy. The method and system also enable users to remotely open and close the garage door via the internet.

Abstract: The 4T2R cell comprises a write transistor, a first variable resistive element, a first transistor, a second variable resistive element, a second transistor, and a charge control transistor. The first transistor is electrically coupled to the first variable resistive element in series, and the second transistor is electrically coupled to the second variable resistive element in series, for providing search paths. For operating in a search phase, a pulse voltage is applied across the gate electrode and the source electrode of the first transistor (or across the gate electrode and the source electrode of the second transistor) for determining whether the gate voltage of the charge control transistor changes larger than a match threshold during the period of the pulse. Different RC-delay of the variable resistive elements controlling the voltage change speed of the gate voltage of the charge control transistor determines the matching result.

The utility meter may then be configured utilizing the configuration file.

Abstract: A storage of nodes of hierarchically structured data uses logical node identifiers to reference the nodes stored within and across record data structures. A node identifier index is used to map each logical node identifier to a record identifier for the record that contains the node. When a sub-tree is stored in a separate record, a proxy node is used to represent the sub-tree in the parent record. The mapping in the node identifier index reflects the storage of the sub-tree nodes in the separate record. Since the references between the records are through logical node identifiers, there is no limitation to the moving of records across pages, as long as the indices are updated or rebuilt to maintain synchronization with the resulting data pages. This approach is highly scalable and has a much smaller storage consumption than approaches that use explicit references between nodes.

Abstract: An electrochemical piezoelectric sensor is disclosed. The sensor includes a piezoelectric substrate, three (or more) electrodes over a first surface of the substrate, and another electrode over a second (opposing) surface of the substrate. An ionic liquid in the form of a film is adhered, bound, immobilized, or otherwise positioned over the substrate and electrodes of the first surface. The ionic liquid film permits the absorption and detection of analytes from a gaseous sample, for environmental gases, example explosive vapors and/or explosive vapor species in the gaseous sample. Detection (optionally including analyte quantitation and qualitative identification) can be performed by both electrochemical and piezoelectric techniques using a single sensor. Systems incorporating and methods of using the electrochemical piezoelectric sensor also are disclosed.
