Tuesday, Feb 17, 2015

Mitsubishi Electric Corporation announced seven new technologies, outlined below, at its annual Research and Development Open House held today at its headquarters in Tokyo, Japan.

No. 2905
Mitsubishi Electric Develops DC Arc-fault Circuit Protection Technology for Solar Power Plants
Minimizes power-generation drops by quickly detecting arc faults and isolating faulty circuit

The company announced today that it has developed a direct-current (DC) arc-fault circuit protection technology for solar power plants that detects any DC arc fault, or high-temperature luminous electrical discharge between DC wiring, and isolates the faulty circuit in just 0.25 second. The technology enables plants both to prevent large decreases in power generation and quickly restore faulty circuits.

Mitsubishi Electric Develops IoT Factory Controller for Future Factories
Collects factory data using IoT technology and collaborates with cloud

The company announced today its Internet of Things (IoT) Factory Controller to connect e-F@ctory, the company’s factory automation (FA) solution, with the cloud for the emerging IoT ecosystem. IoT Factory Controller is now being verified in test operation, with commercialization targeted at April 2016.

 No. 2909
Mitsubishi Electric’s New Technologies Enhance Tsunami Radar Monitoring
Earlier detection allows more time for evacuation of coastal communities

The company announced today that it has developed new technologies to improve the visibility and height estimation of tsunamis by using unprecedented procedures for extracting tsunami information from conventional radar observations of sea surfaces. The technologies, which Mitsubishi Electric will make available during the fiscal year starting in April, are expected to help observers detect tsunamis earlier and give evacuators more time to implement emergency countermeasures.

Mitsubishi Electric Develops Noise-suppression Technology for Hands-free Voice Calls via Car Navigation Systems
Improves clarity in speech communication by drastically suppressing surrounding noises

The company has developed breakthrough noise-suppression technology that significantly improves the quality of hands-free voice communication in noisy conditions, such as making a voice call via a car navigation system. The technology improves voice clarity by removing 96% of ambient sound, including rapidly changing noise from turn signals or wipers, which are difficult to suppress using conventional methods.
