A sound event detecting module for detecting whether a sound event with characteristic of repeating is generated. A sound end recognizing unit recognizes ends of sounds according to a sound signal to generate sound sections and multiple sets of feature vectors of the sound sections correspondingly. A storage unit stores at least M sets of feature vectors. A similarity comparing unit compares the at least M sets of feature vectors with each other, and correspondingly generates a similarity score matrix, which stores similarity scores of any two of the sound sections of the at least M of the sound sections. A correlation arbitrating unit determines the number of sound sections with high correlations to each other according to the similarity score matrix. When the number is greater than one threshold value, the correlation arbitrating unit indicates that the sound event with the characteristic of repeating is generated.

Sound event detecting module for a sound event recognition system and method thereof

Disclosed are an alarm method and system based on voice events, and a building method on behavior trajectory thereof. The system comprises a signal sensor, a voice-event detector and notice and alarm element. In the method, voice signals are captured from a remote unit in an environment. The captured voice signals are classified into at least a voice event. As such, an emergent-event notice is automatically transmitted out if one of predefined emergent events is detected. In the building method on behavior trajectory, messages on voice events are continuously recorded. When the number of the recorded voice events reaches a threshold, a behavior trajectory is constructed, in which a behavior consists of two or more voice events or a single voice event.

Alarm method and system based on voice events, and building method on behavior trajectory thereof

A data collecting method and a master device and a slave device therefor are provided. The method includes the following steps. The slave device receives an environment voice and accordingly generates an audio data. The slave device outputs the audio data through packets of a predetermined format according to a control area network protocol. The master device receives the audio data.

Data collecting method and a master device and a slave device therefor

The present invention relates to a method and a device for dispatching packets with different network protocols and supporting IP-based networks, Non-IP-based networks, controller networks and multimedia networks. With the method and the device of the present invention, the network user can easily add new network services to the existing network structure. Meanwhile, dispatch of network packets is more efficient.

Heterogeneous network packet dispatch methodology

A multiple network service sharing method and a device for the same are provided. With the sub-network aggregation information collecting function and service arbitration function, the network user can easily add new network services to the existing network structure. The method and device support wired, wireless, IP-based and non-IP-based networks.
