    Abstract: Disclosed in the present invention are a method and system for implementing an Internet of Things service. In the present invention: a service generation module generates a description script and a flow script according to a required service, sends the description script and the flow script to an application generation module and a control module, respectively; the application generation module generates an application according to the description script and sends the same to an access module; the access module receives an input of an Internet of Things terminal, processes the input of the Internet of Things terminal using the application, and sends the processed data to a control module; the control module runs the flow script and invokes an execution module to execute an operation according to the data sent by an access module; and the execution module executes an operation according to the invocation of the control module.

    Abstract: A communication end device of a two-way communication system is shown. The device includes an audio signal capture device for capturing local audio to be transmitted to another end device, an audio signal rendering device for playing remote audio received from the other end device, and buffers for buffering the captured and rendered audio signals. The device also includes an audio echo canceller operating to predict echo from the rendered audio signal at a calculated relative offset in the captured audio signal based on an adaptive filter, and subtract the predicted echo from the signal transmitted to the other end device The calculated relative offset that is used by the audio echo canceller for a current signal sample is adjusted if a difference between it and an adjusted relative offset of a preceding sample exceeds a threshold value.

    Abstract: Acoustic echo cancellation, residual echo suppression and sound-source localization/microphone array processes are combined in a two-way voice communication system that uses a microphone array to capture local speech. The processes can be configured according to various alternative architectures and enhancements made to the processes to avoid the adverse effects of non-linear operations in the residual echo suppression on the sound-source localization/microphone array process.
