摘要： Heuristic-based techniques for gas leak source identification are provided. In one aspect, a method for identifying a location of a gas leak source includes: obtaining gas sensor data and wind data synchronously from a gas leak detection system having a network of interconnected motes comprising gas sensors and wind sensors, with the gas sensors arranged around possible gas leak sources in a given area of interest; identifying the location of the gas leak source using the gas sensor data and wind data; and determining a magnitude of gas leak from the gas leak source using the location of the gas leak source and a distance d between the location of the gas leak source and a select one of the gas sensors from which the gas sensor data was obtained. A gas leak detection system is also provided.

摘要： Embodiments of the invention are directed to an integrated sensing system that includes a movable orientation device configured to dynamically position the movable orientation device based on receiving an air-flow. A gas sensor is coupled to the movable orientation device. The gas sensor includes a recognition element configured to detect a chemical in a plume. The movable orientation device is configured to perform a synchronized sensing operation that includes, based at least in part on the movable orientation device receiving the air-flow, moving the movable orientation device to dynamically maintain a predetermined orientation of the movable orientation device relative to a direction of the air-flow. The predetermined orientation includes positioning the gas sensor in a path of the air-flow, wherein the air-flow is influencing the plume to move along the path such that the recognition element is exposed to the plume.

摘要： An accelerometer without internal mechanical attachments. Three parallel cylindrical magnets are fixed within a housing. Each cylindrical magnet has a long axis extending through the housing and a cylindrical cross-section. The cylindrical cross-sections of the cylindrical magnets are organized to form a triangular formation. The magnetization of the cylindrical magnets is tangential to the triangular formation. A diamagnetic mass object levitates within the three cylindrical magnets by the magnetization of the cylindrical magnets at an equilibrium position near the center of the triangular formation and near a central axis of the three parallel cylindrical magnets when no external force is applied. Sensors detect the location of the diamagnetic mass object when the diamagnetic mass object is displaced from the equilibrium position near the center of the triangular formation and the three parallel cylindrical magnets by an external force to the housing.

摘要： Techniques for facilitating event driven gas sensing and source attribution are provided. In one example, a computer-implemented method comprises generating, by a device operatively coupled to a processor, a gas sensor signal indicative of sensing a gas based on the sensing the gas by one or more sensors. Additionally, the computer-implemented method can comprise converting, by the device, the gas sensor signal from an analog signal to a digital signal to identify one or more peak events based on the digital signal being determined to have satisfied a condition.
