TOKYO— Toshiba Corporation (TOKYO: 6502) has developed a world-first AI technology that can determine actual-scale 3D measurements from only monocular camera images taken under various conditions, such as those taken from a distance with a zoom lens or with autofocus. Using several photos taken from a distance by a monocular camera during infrastructure inspections, this AI facilitates easy measurements of the size of areas for repair without the need to approach dangerous and difficult-to-inspect areas such as high places and inclinations. The conventional use of only a monocular camera provides only relative values, requiring gyroscope to obtain absolute values or basic information about sizes. However, the developed AI can provide absolute values by combining relative depth information obtained from multiple viewpoints of a monocular camera with blur information contained in the captured images. Considering that the average age of infrastructure facilities in Japan now exceeds 35 years, this AI can be used to develop efficient maintenance plans that prioritize and realize appropriate repairs without excess or deficiency. Toshiba has been developing robot-integrated management and inspection image analysis technologies like those shown in Figure 1 to save labor and automate infrastructure inspections, and the newly developed technology improves performance in size measurements. Toshiba will present the details of this technology on November 22 at the British Machine Vision Conference 2021 (BMVC 2021).

TOKYO─Toshiba Corporation (TOKYO: 6502) has developed the AI technology that automatically generates physical models for detecting equipment abnormalities and determining the causes of those abnormalities in social infrastructure equipment. The AI automatically generates a physical model that describes the states and motion of a target device from measured time-series data. In addition, the AI shows not only abnormalities in equipment but also the cause of the occurrence of abnormalities based on physical phenomena, which has been difficult in the past. For example, the model made by the AI might indicate that an increase in equipment temperature is due to clogging dust, making improvement measures easier to formulate. The AI responds to complicated phenomena such as sudden changes in temperature and airflow, and can be applied to the maintenance of infrastructure equipment with complicated mechanism of abnormalities offurencethat is abnormalities with complicated occurrence mechanisms. It will improve reliability of facilities and contribute to resilience in social infrastructure. Toshiba will present the details of this technology on November 5 at IMECE 2021, which will be held online.

TOKYO─Toshiba Corporation (TOKYO: 6502) has successfully developed draw solutes , an osmotic pressure material for the forward osmosis membrane method to concentrate and extract components or substances (valuable materials) from aqueous solutions. This material both reduces energy consumption to one-fourth and increases the concentration rate by 2.4-fold compared with conventional concentration methods. Conventional concentration technologies rely on evaporation or application of high pressure, and thus require a huge amount of energy. On the other hand, this newly developed technology uses the principle of osmotic pressure causing spontaneous removal of water from aqueous solutions, thereby achieving energy-saving concentration. After being used for concentration treatment, the newly developed osmotic material can be separated from water and then reused. This technology can be used in the manufacturing of chemicals and pharmaceuticals, effluent treatment, and recovery of rare metals. It will also enable the reuse of water and the sustainable use of natural resources and reduce the burden on the environment, thus contributing to a recycling society. Toshiba will present details of this technology online at the 52nd Autumn Meeting of the Society of Chemical Engineers, Japan (September 22-24, 2021, Tsushima Campus, Okayama University).
