Toshiba has developed an ultra-low-power analog AI accelerator chip for embedded systems. This technology realizes multiply-accumulate operation—which accounts for the majority of neural network operations—using only one-eighth the power of current digital circuits. This chip will accelerate the introduction of AI technologies into embedded devices that operate on battery power, energy harvesting, or remote wireless power, which has been difficult until now.

Toshiba has developed a gate dielectric process technology for improving the reliability of GaN power devices, which are expected to be the next generation of semiconducting power devices. Application of this technology will greatly reduce the variation in characteristics such as threshold voltage. The use of GaN-MOSFETs with this technology is expected to improve the reliability of GaN power devices and contribute to their further spread. The details of this technology will be presented at the International Electron Devices Meeting (IEDM) in San Francisco on 6 December 2017.

Toshiba has developed a wireless multi-hop video transmission technology that applies a bucket brigade method to realize full HD video transmission from multiple wireless cameras without any delay. This technology enables autonomous configuration of wireless networks considering the installation environment of surveillance cameras, making it possible to freely arrange surveillance cameras or construct wide-area video surveillance systems that connect multiple drone-mounted cameras. This technology will be demonstrated on 9 November 2017 at the Toshiba Open Innovation Fair 2017.

Toshiba has developed a new gate-insulating film process technology for SiC-MOSFETs that reduces resistance in their channel region by about 40%, and that is expected to reduce total device resistance by as much as 20%. SiC-MOSFETs are widely seen as next generation, advanced semiconductor power devices, and this reduction of power consumption will contribute to their adoption. Details of the technology was announced at the International Conference on Silicon Carbide and Related Materials (ICSCRM) in Washington DC, on September 18.

TOKYO-Toshiba Corporation (TOKYO: 6502) and Toshiba Research Europe Limited’s Cambridge Research Laboratory in the UK have brought the enhanced security of quantum cryptography closer to practical realization with development of the world’s fastest quantum key distribution device. The device has achieved a key data distribution speed of 13.7 megabits per second *1. The speed is about seven times the previous fastest quantum key distribution speed: the 1.9Mbps that Toshiba achieved in 2016.

Toshiba Corporation has developed a post-quantum public key cryptosystem in collaboration with Hokkaido University of Education, Kyushu University, and the National Institute of Advanced Industrial Science and Technology. The security of the cryptosystem is based on the problem of finding a small solution to a multivariate non-linear indeterminate equation, which is expected to be computationally hard, even with quantum computers. It is expected to offer security and calculation efficiency equivalent to or better than those of lattice-based cryptosystem, and to offer a promising candidate for post-quantum cryptosystems. Details were presented at SAC2017, an international conference held in Ottawa, Canada, on August 16–18, 2017.

Toshiba has developed AI technology that uses video feeds from multiple surveillance cameras to track the movements of people in shopping malls, train stations, arenas and other large facilities. Although it receives feeds from cameras in locations throughout the facility, the technology realizes high precision with low computation load, allowing routes taken by multiple people to be tracked at the same time. The technology will be reported at the 20th Meeting on Image Recognition and Understanding (MIRU2017), a major Japanese conference on image recognition, on August 8.

Toshiba has developed a hydrogen gas sensor that consumes less than 1% the power of conventional devices(Note 1) without loss of detection speed. It is based on a Toshiba-developed microelectromechanical system (MEMS) structure that employs a palladium-based metallic glass(Note 2) to realize both rapid detection and low power consumption, overcoming the usual trade-off of conventional sensors. The sensor can be fabricated on semiconductor manufacturing lines, allowing low-cost mass-production. Details on the technology will be presented on 20 June at the Transducers 2017 international conference held in Taiwan.

Toshiba has achieved two breakthroughs in spintronics technologies for Internet of Things (IoT) devices: an ultra-sensitive spintronic strain-gauge sensor element for micro-electro-mechanical-system(MEMS(Note 1)) sensors that is 2500 times as sensitive as conventional metal strain-gauges and over 100 times as sensitive as semiconductor strain-gauges; and the world's first(Note 2) spintronic MEMS microphone integrating a spintronic strain-gauge sensor element on the MEMS diaphragm, which has experimentally demonstrated accurate detection of ultrasonic sounds inaudible to the human ear. Details on the technologies will be presented on June 19 at the Transducers 2017 international conference held in Taiwan.

Toshiba has developed a system that performs fluorescence imaging(Note 1) of cell clusters during culturing in an incubator(Note 2) without using an objective lens. The prototype can distinguish individual cells in clusters, and is the first in the world(Note 3) to achieve a spatial resolution below 10 micrometers(μm), three times finer(Note 4) than that of a previously proposed similar technology. Details of the development will be published on 20 June at the "Transducers 2017" international conference held in Taiwan.

Toshiba has developed an evaluation technology for visualizing the relationship between the performance of electron conduction channels (current paths) and crystal structures in nano-sized polycrystalline silicon(Note 1) thin-film transistors. This technology allows direct evaluation of relationship between electrical characteristics and crystal structures in polycrystalline silicon transistors in electronic devices, which are difficult to elucidate by conventional methods, and the identification of factors in the deterioration of electrical properties. Details of the technology were announced on April 6, 2017 at the International Reliability Physics Symposium (IRPS 2017) in Monterey, CA, USA.

TOKYO─Toshiba Corporation (Tokyo: 6502) today announced the results of field tests of electric buses charged with its wireless rapid rechargeable battery system. The tests, carried out with the cooperation of Waseda University, concluded that using the buses to replace standard diesel buses could cut CO2 emissions from daily operation by up to 60%1. The project was supported by the Ministry of the Environment's Low Carbon Technology Research and Development Program.
