Abstract: Implementations described and claimed herein provide systems and methods for flood hazard zone modeling. In one implementation, one or more relevant stream segments are identified from an input stream network. One or more cross profiles are defined for one or more selected points on the relevant stream segments, with the selected points located within a flood hazard area. A high resolution flood level elevation map is generated by interpolating flood level elevation from the selected points. A flood depth map is generated having a flood depth value for each of the selected points computed as a difference between the high resolution flood level elevation map and a terrain elevation. One or more flood zones are defined in the flood depth map. The flood zones have a positive flood depth for a return period.

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.

Abstract: A three-axis magnetic field sensing device, a magnetometer, and methods of fabricating and testing are presented. The magnetometer comprises a plurality of sloped surfaces. A plurality of magnetic sensing units is disposed on the slopes. A magnetic field can be measured by the sensing units. Each of the three orthogonal-axis components of the magnetic field, a Euclidean vector, can then be solved by using a simple algorithm as an expression of the sensing unit measurement values and slope angles. Polarization, testing and characterization of the device could be done by applying a magnetic field along a common axis to all sensing units, along which each sensing unit has sensitivity.

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.
