This paper describes an intelligent ankle assistive robot which provides assistive power to reduce ankle torque based on an analysis of ankle motion and muscle patterns during walking on level and sloped floors. The developed robot can assist ankle muscle power by driving an electric geared motor at the exact timing through the use of an accelerometer that detects gait phase and period, and a potentiometer to measure floor slope angle. A simple muscle assistive link mechanism is proposed to convert the motor torque into the foot assistive force. In particular, this mechanism doesn't restrain the wearer's ankle joint; hence, there is no danger of injury if the motor malfunctions. During walking, the link mechanism pushes down the top of the foot to assist the ankle torque, and it can also lift the foot by inversely driving the linkage, so this robot is useful for foot drop patients. The developed robot and control algorithm are experimentally verified through walking experiments and EMG (Electromyography) measurements.

The Law method is observing the temporal bone. There are two types of methods: the double angle method, which manipulates the center ray angle of the tube twice, and the single angle method, which manipulates once. The purpose is to increase the reproducibility of the image by making vertical incidence by making an assistive device using a 3D printer. Two assistive devices with a wedge-shaped 8.5 × 10 × 2.3 cm, an inclined surface of 7.5 cm, and an inclination angle of 15° were fabricated. Assistive devices can be combined with each other in the form of grooves, and PLA (Poly Lactic Acid) is used as a material. In the first experiment, 10 examiners operated the tube 15° in the caudad direction and 15° in the anterior direction, and measured it with a protractor to conduct a reproducibility experiment. Second, two examiners acquired vertically incidence images using the existing law method and assistive devices, and measured the distance between each measurement point to evaluate the reproducibility. The tube center ray angle reproducibility experiment was not statistically significant, but the angle difference was up to 9° between examiners. The reproducibility experiment of radiographic images was not statistically significant with the conventional method, and the method using an assistive device was statistically significant. Therefore, regardless of skill level, an image capable of securing reproducibility, which is the advantage of vertical incidence, could be obtained.

Research and development of Assistive Technology (AT) for blind people is primarily focused on assisting mobility and improving access to information. Some particularly useful devices for aiding access to information and communication are DAISY players used with talking books, screen readers for reading screens, video magnifiers to aid low vision, Braille displays, and Braille PDAs. These essential devices have been successfully commercialized and have assisted many visually impaired people. Assistive technology devices for visually impaired people are called sensory substitution devices, because these devices substitute tactile or auditory functions for visual functions. The tactile interfaces of sensory substitution devices such as Braille displays and Braille PDAs have a bimorph type of piezoelectric actuator that forms a Braille (pin) of the Braille cells by moving up and down. KGS Corporation of Japan has more than 80% share of the worldwide market for these Braille cell actuators. Commercializing it for the first time in the world. This paper reviews the various endeavors in Japan in the research and development of tactile displays, such as Braille displays and Braille PDAs. Furthermore, it discusses sensory substitution devices that use tactile displays, focusing especially on the rotating Braille display we have developed.
