Development of a technology for high-performance measurement of group sizes (Dec. 2015) We have developed a new technology for precisely calculating the number of persons and vehicles in a wide-angle video shot from a single camera. This technology is applicable to even videos where target objects overlap or are extremely small, and publicly released evaluation image data^{(Note 1)} shows the highest performance yet achieved in terms of calculation error. We will present the results of this technology on 15 December at ICCV 2015 (Santiago, Chile), the world's largest computer vision conference.

New technology to project expansive virtual reality images inside the magnet bore -Reducing patient anxiety caused by the confined MRI examination space- (Dec. 2015) Toshiba Corporation and Toshiba Medical Systems Corporation have developed a technology for displaying expansive virtual reality images inside the bore^{(Note 1)} of MRI systems. High reality images are projected onto a dome-shaped screen (dome screen) in the bore to take the patient's attention away from the actual examination space. This new technology is a reference exhibit^{(Note 2)} at the 101st Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA 2015, November 29 to December 4, Chicago).

Foreign Language Meeting Support System with Japanese–English and Japanese–Chinese Interpretation and Translation Functions (Oct. 2015) TOKYO—Toshiba Corporation (TOKYO: 6502) today announced that it has developed a Japanese-English and Japanese-Chinese meeting support system to assist communications between foreign nationals in business meetings and the like, featuring captioned translations that are displayed directly on the user's computer or device screen in real time.

Toshiba's New Molecular Catalyst for Artificial Photosynthesis Converts Carbon Dioxide Directly into Ethylene Glycol (Sep. 2015) Toshiba has developed a prototype of a highly efficient molecular catalyst that converts carbon dioxide into ethylene glycol, a useful industrial raw material, without producing other and unwanted by-products.

Demonstration of a new technology for a multilayer magnetic recording to realize high-density hard disk drives (Jul. 2015) We have demonstrated a new technology in which microwave magnetic fields are used to reverse magnetization directions by selecting layers in a multilayer magnetic medium. The developed magnetization reversal technology is expected to realize increased hard disk drive (HDD) capacity by adopting high-density, multilayer (three-dimensional) magnetic recording media.

Toshiba novel method for quantifying cerebrospinal fluid flow dynamics uses magnetic resonance image analysis (Jun. 2015) Toshiba has developed a novel method for automatic computation of cerebrospinal fluid (CSF) flow velocity that uses advanced image processing techniques on non-contrast enhanced magnetic resonance (MR) images. This method can improve the diagnosis of CSF-related conditions, including dementia caused by idiopathic normal-pressure hydrocephalus (iNPH).

Toshiba Develops New Chip Authentication Technology Using Transistor Noise (Jun. 2015) Toshiba has developed a novel method of utilizing random telegraph noise (RTN) originating from insulating material faults to implement a physical unclonable function (PUF), an important security technology that has attracted considerable attention in recent years. The method, which will contribute to the creation of safe and secure cloud services for smart communities, was announced at the VLSI Technology Symposium, an international conference on semiconductor devices to be held on June 16 in Kyoto, Japan.

Toshiba Develops SSD Simulation and Analysis Platform for Design Optimization (Jun. 2015) Toshiba Corporation has developed an SSD^{(Note 1)} design optimization platform that realizes efficient analysis of various SSD simulations, greatly reducing work on design optimization. Toshiba will present details at the Design Automation Conference in San Francisco, California on June 8.

Toshiba and Landis+Gyr Make Proposal on IEEE 802.21d Standardization for Security of Multicast Communications (Apr. 2015) Toshiba Corporation and Landis+Gyr have jointly proposed to the IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 802.21d Task Group a draft technical document for standardization of group key management systems and public key certificate management systems, and the sponsor voting for which has been completed. Once approved by the IEEE Standards Association, the proposal will be established in the form of standards and norms.

Super High Quality Image Processing Technology A Compact Image Sensor Providing Image Quality on Par with Larger Sensors (Apr. 2015) Toshiba has developed a super high quality image processing technology that achieves image quality comparable to that of larger image sensors. This new technology is able to apply a compact image sensor like the ones in smartphones and in-vehicle cameras. Our technology sequentially processes a continuous series of captured images to realize a high image quality previously attainable with only larger image sensors.

Development of a nonvolatile memory circuit for high-performance processors using new types of magnetic memory elements (Mar. 2015) We have developed a spin-transfer torque magnetoresistive random-access memory (STT-MRAM) circuit for use in high-performance processors and system-on-a-chip (SoC) integrated circuits, implementing a 1-Mb class of new magnetic materials. The newly developed memory circuit allows low-power, high-efficiency, high-speed performance in energy-efficient magnetic tunnel junction (MTJ) memory.
The proposed memory circuit provides speed performance capable of 3.3-ns access to in-cache memory. The circuit furthermore consumes approximately 80% less power than conventional static RAM (SRAM) as embedded memory, giving it the best power performance of any type of embedded memory. Details of the proposed technology will be presented on February 24 at the 2015 International Solid-state Circuits Conference in San Francisco.

Development of a Cloud System for Instantaneous Remote Control of over One Million Devices on the Internet of Things (Jan. 2015) Toshiba has developed a cloud system for instantaneous remote control of over one million devices on the Internet of Things (IoT). In the IoT world, in which diverse devices, such as home devices and sensors, are connected to the Internet, multiple control command relay servers are necessary with a scale of over one million devices. We developed a system that can connect more than 100,000 devices using a server instance that is not high performance (equivalent to a regular laptop computer with 4 GB of memory). Furthermore, a low-latency communication is maintained by always connecting the controlling mobile terminal and the controlled home device to the same server. The system also dynamically increases or decreases the number of servers depending on the number of connected devices. This technology was unveiled at IEEE CCNC 2015^{(Note 1)} that was held from January 9 to 12.
