Abstract: Provided is to determine a walking state when a target person uses a stick. A walking state determination device according to an embodiment of the present invention includes: an acquisition unit that acquires feature information indicating a feature of a motion of a target person when using a stick, based on first measurement data acquired from a first sensor installed at the stick and second measurement data acquired from a second sensor installed at the target person; and a determination unit that determines a walking state of the target person, based on the acquired feature information.

Abstract: Provided are a reference scale and dimension measurement system that make it possible to maintain accurate measurement even if the reference scale is not disposed or projected on a measurement surface. A dimension measurement device according to the present invention is provided with: a reference scale extraction means for extracting, from photographed image data including a reference scale that includes a film that has a pattern for displaying a length reference formed on the surface thereof and a lens that is in contact with the film, an image in which an image of the length reference is formed on the basis of the relationship between a pattern function expressing the length reference projected onto the lens according to variation in a prescribed angle between the reference scale and the optical axis of a photography device and an image formation color function indicating the image of the length reference formed on the imaging device; an object of measurement extraction means for extracting an object of measurement image from photographed image data including the reference scale; and a dimension calculation means for calculating a dimension of the object of measurement on the basis of a dimension of the image in which the image of the length reference is formed and the image of the object of measurement.

Abstract: A design support device having a permissible power supply fluctuation deriving unit and a target impedance deriving unit. The permissible power supply fluctuation deriving unit derives the fluctuation in the power supply voltage that is permissible on the basis of jitter-voltage correlation information, which indicates the correlation between the power supply voltage fluctuation generated in an I/O buffer and the jitter generated by the power supply voltage fluctuations, and jitter constraint information, which is for stably transmitting a signal, for the generated jitter. The target impedance deriving unit derives a target impedance in the permissible range of impedance for a power supply circuit, on the basis of information on the signal operating current flowing through the power supply circuit of the I/O buffer, and the power supply voltage fluctuation.

Abstract: A ground reaction force load difference calculation unit configured to calculate a ground reaction force load difference that is an amount of a load relief for a user, on the basis of a first measured value that a weight, based on a weight of the user and a weight of the load reduction device that reduces a load on the user and has a mechanism that holds luggage and is at least worn by the user, is transmitted to a ground contact surface and of a second measured value that a weight based on the weight of the user is transmitted to the ground contact surface; and a torque control unit configured to control, on the basis of the ground reaction force load difference, torque that is output by the load reduction device to reduce the load on the user at an joint of each leg of the user.
