As Japan is facing a hyper-aged society, Personal Health Records (PHRs), which patients collect and manage their own healthcare information, is currently attracting attention. NEC is advancing R&D to collect "symptom data," "drug adherence data" and "continuously monitored blood pressure data" by directly and objectively accessing the source which are hard to gather sufficiently. With this technology, NEC will contribute to a reduction in the wasteful medical expenses caused by forgetting to take medicines, to the new drug development earlier with quality improvement of clinical trials, and to support higher accurate diagnoses and better medical care.

The rapid size reduction of wireless equipment has led to a drop in the communication performance caused by the electromagnetic noise that is generated inside the equipment becoming an important issue. The electromagnetic bandgap (EBG) structure that is a kind of metamaterial is attracting attention as a new technology for reducing electromagnetic noise. This paper introduces a newly developed EBG structure, which is a technology developed originally by NEC. Wi-Fi home router products that apply this structure as a world first technology are also discussed. Source

Advances in image recording/playback device technologies have made it possible to provide next-generation broadcasting services that deliver ultra high definition video that surpasses terrestrial HD (High Definition) broadcasts. The ultra high definition digital video of 4K comprises a pixel count that is 8 times higher than HD, enabling it to convey a scene's depth and presence more effectively to the viewer. However, since the amount of image data that must be processed is enormous, a highly efficient digital video compression technology becomes necessary for image transfer. And since the ultra high definition digital video will be used for sports and other live broadcasts as well, real-time compression is a necessity. In this paper we discuss NEC's ultra high definition digital video compression technology and real-time HEVC compression unit corresponding to 4K, as well as our future activities. Source

As usage of the cloud expands, cloud data centers will need to be able to accommodate a wide range of services including not only office applications but also on-premises services and in the future, the Internet of Things (IoT). To meet these needs, it requires the ability to simultaneously handle multiple demands for data storage, networks, numerical analysis, and image processing from various users This paper introduces a Resource Disaggregated Platform that will make it possible to perform computation by allocating devices from a resource pool at the device level and to scale up individual performance and functionality. By using standard conventional hardware and software resources to build these disaggregated computer systems, it is possible to deliver faster, more powerful, and more reliable computing solutions effectively that will meet growing customer demand for performance and flexibility. © 2015, NEC Mediaproducts.

The NEC Group has developed a piezoelectric vibration sensor that features sensitivity at about 20 times that of previous models. A vibration sensor is a device that corresponds to the auditory and tactile organs of the human body. The real world is flooded with vibration information generated by humans, goods and environments. Our recently developed vibration sensor can collect minute waveform data that has been hitherto undetectable and has therefore not been utilized. The device extracts the frequency components that present anomalies and analyzes their significance by means of cloud computing, so as to implement a safe and secure society by connecting accurate identification of situations and circumstances for the prevention of adverse events. This paper introduces features of the newly developed vibration sensor and discusses efforts being made for the development of its applications. Source
