A data management terminal for a laser gas detector, and a data management method thereof are provided. The data management method includes: the data management terminal establishes a connection to a communication port of the laser gas detector, and obtains target gas concentration data in a target region through the connection; the data management terminal creates a target gas concentration log according to the target gas concentration data; and the data management terminal transmits the target gas concentration log to a server.

A multi-core sensor system in taxi roof light is provided. The multi-core sensor system can intelligently determine whether the change is caused by the sub-sensor failure or sudden pollution, when the data detected by the sub-sensor suddenly changes dramatically, so as to increase the reliability of detection data of the sub-sensor. The multi-core sensor system can automatically determine whether the repair is needed when a device fault occurs, thereby ensuring the continuity of the sub-sensor detection data; which has significant value for continuous monitoring required for a haze treatment operation. In addition, human and material resources for device maintenance may be saved, thereby reducing waste.

A sensor tag which in use will be affixed to a vehicle for obtaining vehicle telematics data includes a battery for powering the tag and a processor running executable code to process accelerometer data. An accelerometer measures the acceleration of the tag and thereby of the vehicle, and also controls the operation of the processor. A memory is used for storing a unique tag identifier of the tag and for storing trip data including information about trips and acceleration data. Finally, a communication module is used for short range wireless communication with a mobile communications device located in the vehicle via a short range wireless communications protocol, the communication module transmitting the tag's unique identifier and a sequence of time stamped acceleration data. The mobile communications device obtains GPS data, combines this with the acceleration date and transmits this to a server for analysis.

Detection of placement of dental aligners in patient mouth on teeth for indication of wearing compliance. Described herein are apparatuses and methods for detecting wearing, including compliance. In some variations these apparatuses and methods may include a sensor configured to detect deflection of the one or more deflectable structures. In some variations, these apparatuses and methods may include a proximity sensor coupled to the appliance shell and configured to generate sensor data when in proximity with intraoral tissue.

A system and method for a telematic application on a mobile electronic device that can include detecting, in the telematic application, vehicular travel; collecting, in the telematic application, driver status identification data; determining a driver status based on the driver status identification data; recording the driver status; and recording telematic data based on the driver status.

A method for isolation and restoration for a multi-core sensor system within a taxi is provided. This method can intelligently determine whether the reason for an abrupt dramatic change in the data detected by sub-sensor is a sensor fault or sudden pollution, so as to increase the reliability of the data detected by the sub-sensor. This method can automatically determine if the repair can be performed when a device fault occurs, so as to ensure the continuity of the detection data of the sub-sensor, which has significant value for continuous monitoring required for a haze treatment operation. In addition, human and material resources for device maintenance may be saved, thereby reducing waste.

A method for determination and isolation for abnormal sub-sensors in a multi-core sensor. It can be intelligently determined whether the reason for an abrupt dramatic change in sensor data is a sensor fault or sudden pollution, so as to increase data reliability. A data online rate is increased if a repair can be performed via automatic determination when a device fault occurs, which has significant value for continuous monitoring required for a haze treatment operation. In addition, human and material resources for device maintenance may be saved, thereby reducing waste.

A computer-implemented method, system, and computer-readable medium for automatically generating a combined display of measurement data representing a combined measurement, such as a multiphase parameter, includes establishing, by a mobile computing device, communication connections with a plurality of measurement devices configured to generate measurement data. The mobile computing device receives the measurement data generated by the plurality of measurement devices, and in response to information indicative of the measurement data representing related parts of a combined measurement, the mobile computing device automatically groups the measurement data received from the measurement devices and automatically displays the grouped measurement data in a combined display that shares at least one axis of measurement. In at least one embodiment, the combined measurement is a multiphase parameter, such as a three-phase electrical parameter, and the combined display is a graph in which the measurement data shares at least one axis of measurement, such as time.

A method for determining a false negative rate of mobile monitoring and requisite number of mobile monitoring vehicles. The method focuses on road network of an urban area, by installing air pollution detection equipment on the mobile monitoring vehicles, to monitor air quality of the urban area. The method includes establishing a curve model of monitoring times for the mobile monitoring vehicles, determining two parameters of expected indicator: covered range, number of scheduled detections; and finding out a requisite number (C.sub.0) of the mobile monitoring vehicles, corresponding to a curve model which meets the two parameters of expected indicator.
