Abstract:
The present disclosure provides a light concentrating device for a photochemical reaction device capable of decreasing abnormal chemical reactions that occur when intensity of sunlight is too strong for an electrode of a photochemical reaction device. The light concentrating device includes a lens for concentrating sunlight on the electrode of the photochemical reaction device, a lens movement device for moving the lens in an optical axis direction, an image pickup device for picking up an image of transmitted sunlight that passes through the electrode, an abnormal chemical reaction detector for detecting presence of an abnormal chemical reaction on the electrode based on information on the image picked up by the image pickup device, and a lens position controller for controlling the lens movement device to move the lens to decrease occurrence of the abnormal chemical reaction when the abnormal chemical reaction detector detects the abnormal chemical reaction.
Abstract:
An assist garment worn on a part of a human body includes a plurality of garment-fitting actuators that are placed linearly along at least one end portion of a garment body and driven to extend and contract, a plurality of assisting actuators that are placed linearly on the garment body to cross the fitting actuators and driven to extend and contract, and a controller that individually controls the drive of the assisting actuators and the drive of the fitting actuators.
