Methods and system are described for monitoring an environment. Acoustic data collected from microphones distributed within the environment are received. Sound sources are identified from the received acoustic data as generative of sound detected by the microphones. An acoustic scene of the environment is characterized by application of acoustic-scene characterization rules to the received acoustic data. The acoustic scene of the environment is identified as anomalous according to parameter values deviant from a set of parameter values defining nonanomalous acoustic scenes. A remedial response to the environment is initiated in response to identifying the acoustic scene of the environment as anomalous.

The present invention is directed specifically to methods for reducing the bandwidth requirements for broadcasting traffic information to a vehicle navigation system. The traffic information broadcast to the system using the bandwidth conserving methods of the present invention generally includes traffic flow information and traffic incident information. In one embodiment, the vehicle navigation system filters traffic information to a certain range to expedite traffic calculation, to save on processing hardware, and to reduce bandwidth needs. Alternately, bandwidth conservation may be achieved by providing weight factors and threshold prioritizing when a broadcast limit is close to being reached or exceeded. In another embodiment, bandwidth reduction is achieved by not broadcasting free-flow traffic information and / or displaying only traffic information that indicates a traffic problem. Another method of the present invention to reduce bandwidth needs is directed to reducing broadcast of static traffic information.

The invention relates to the field of testing, in particular to a TeraHertz wave Doppler interferometry instrument and method to solve the problems of the prior art. The instrument comprises a reference light adjusting device, a target detecting device and a data processing device. Interference signals processed by a THz wave beam splitter are filtered through a THz filter, and the filtered interference signals are detected through a THz wave detector; then signals output by the THz wave detector are recorded through an oscilloscope, and finally data acquired by the oscilloscope are analyzed and processed through a processor, so that the movement distance and speed of a target relative to an interferometer are obtained.
