Systems and methods for wirelessly recording multi-track audio files. In some aspects, each performer is equipped with a local audio device capable of locally recording the respective performer's audio while also transmitting it to a master recorder. Functions of the local audio device may be adjusted remotely. The locally recorded audio may be used to repair or replace any audio lost or corrupted during transmission to the master recorder. Such repair or replacement may be performed electronically or via playback of the locally recorded audio. In other aspects, a master recorder is not required since all locally recorded audio may be combined or otherwise processed post-recording. Locally recorded audio may include identifiers to aid in post-recording identification of such audio. A multi-memory unit is provided to facilitate manipulation and processing of audio files. A method for automatically adjusting local audio device power mode based upon recorder status is also disclosed.

An abnormal area is detected using an initial spatial weights matrix between pairs of air quality sensors in a plurality of air quality sensors distributed across a geographical area and air quality data for each air quality sensor. The spatial weights matrix utilizes a distance between pairs of air quality sensors and wind direction through the geographical area. The initial spatial weights matrix and air quality data are used to calculate a plurality of local moran's indexes, one for each air quality sensor. The plurality of local moran's indexes are used to divide the plurality of air quality sensors into four groups. The groups are classified as proper or improper, and the proper groups are identified as abnormal areas.

A method for protecting a signal for transmitting a sequence of measurement values to a signal processing unit. The method includes a step of reading in at least one sequence of measurement values from a sensor and a step of processing the measurement values using a cyclical processing specification in order to determine a varied measurement value for each of at least two measurement values. Finally, the method comprises a step of sending the varied measurement values to the signal processing unit as measurement values from the sensor.
