Systems and methods described herein are directed to a specialized Internet of Things (IoT) device deploying both acoustic and radio wave signals. In example implementations described herein, camera data and acoustic sensor data is integrated to generate an acoustic sensor heatmap for the holistic sensing systems in an IoT area.

Holistic sensing method and system

Systems and methods involving integrating camera and acoustic sensor data, and automatically capturing the acoustic sensor heatmap for the holistic sensing systems in Internet of Things (IoT) systems. In particular, example implementations described herein capture the local sound noise environment or localized noise profiles (e.g., noise fingerprint) adaptively to the change of noise profiles and automatically apply captured noise profiles to the streaming noise reduction in signal processing for industrial IoT areas.

Adaptive acoustic sensing method and system

This invention aim to improves the flexibility of data flows management from sensor to cloud, datalake or other system, which can manage the overall data flows within the system and control them dynamically. As a result, it can reduce transmission cost and storage cost properly.

Method to manage data flow for edge-core distributed analytics systems

A communication system includes a mobile terminal, a base station, a first gateway device, a second gateway device, a flow measurement server, a quality management server, and an operational terminal. A predetermined flow is extracted by a quality management server, and the extracted flow is summarized for each communication path. A distribution of the communication quality of the flow for each communication path is displayed on a display unit of the operational terminal.
