Abstract: A subdural sensor includes: a substrate formed of a flexible material; and at least one type of sensor part mounted on the substrate. The substrate has an elongated shape, and includes: a sensor area in which the sensor part is mounted and a wiring pattern connected to the sensor part is formed; a wiring area contiguous with the sensor area, the wiring pattern extending in the wiring area; and a connector area contiguous with the wiring area, the connector area being an area on which a connector to be connected to the wiring pattern extending from the wiring area is mounted. A tip part of the sensor area has a planar shape that curves convexly toward an outer periphery, and a side shape that curves toward a first surface, the first surface being on the side of a dura mater when the subdural sensor is inserted into the subdural space.

Abstract: Embodiments include a patch-type, ultrasound sensor system and method to monitor the function and motion of a patients anatomical structure, comprising processing at least one received ultrasound image using one or more analytical tools, including radon transformation, higher-order spectra techniques, and/or active contour models, to generate at least one processed ultrasound image; inputting the at least one processed ultrasound image into a deep learning Convolutional Neural Network to obtain an automatic classification result selected from two or more classes indicating the functional state of the anatomical structure. The patch-type, ultrasound sensor system can communicate via a wireless or wired connection. The monitoring can be at rest or during surgery or other procedure or whilst the subject is exposed to any physiological stressors as part of medical examinations, and can be adapted for use in monitoring the function of body structures including the heart, blood vessels, lungs or joints.

Abstract: An electrocardiogram waveform measurement system is configured to be suitable for measuring an electrocardiogram waveform with high precision using multiple electrodes provided to an article of clothing. A measurement unit performs measurement in a state in which multiple fabric electrodes are grouped into multiple channels. A signal measured by the electrodes for each channel is evaluated in a two-dimensional manner based on the number of times an R wave is detected by an R wave processing unit in a predetermined period of time and a degree of data concentration in a dynamic range acquired by a degree-of-concentration calculation unit. A channel selection unit selects the optimum channel.

Abstract: Proposed are a brain signal measurement system and the like, capable of carrying out in vivo placement of measurement units for measuring brain signals with a minimally invasive operation, as well as of easily adjusting the position of each measurement unit. The brain signal measurement device includes sensors to be provided in a space between a dura mater and an arachnoid mater, and a holding unit for holding the sensors. The sensors are connected by a shape-memory unit. The sensors are inserted through a hole penetrating through the scalp and so on, into a space between the dura mater and the arachnoid mater. The diameter of the hole can be equal to or smaller than 1 cm. By electrical heating, the shape-memory unit changes its shape to change positions of the sensors, and thus subdural electrodes can be placed with a minimally invasive operation.

Abstract: A problem to be solved by the invention is to provide a small-sized display device in which image data with a large information amount, such as moving images, large capacity mail data, and the like are displayable on a large-sized screen. A mobile telephone (1) equipped with a display device includes an accommodating unit (5) arranged on one side of a main unit (2), and this accommodating unit (5) is provided with a winding/unreeling shaft (7) and can accommodate a display unit (4) including a polymer liquid crystal film or the like that can be wound up in a rolled-state by the winding/unreeling shaft (7). The display unit (4) is unreelable by reeling it out or pulling it out to protrude from an opening (6) of the accommodating unit (5).
