Abstract: An assistance apparatus includes a first wire and a second wire that couple an upper-body belt and a left knee belt to each other, respectively, a third wire and a fourth wire that couple the upper-body belt and a right knee belt to each other, respectively, and a motor. When assistance is stopped, the motor is configured to reduce tension of the first wire during a first stop period starting in a boundary period in a first period and ending in a start period of a second period, generate no tension in the second wire during the second period, reduce tension of the third wire during a second stop period starting in a boundary period in a third period and ending in a start period of a fourth period, and generate no tension in the fourth wire during the fourth period.

Abstract: An assistance apparatus includes a first and second wires coupling an upper-body belt and a left knee belt to each other on or above a front and back parts of a body of a user, respectively, a third and fourth wires coupling the upper-body belt and a right knee belt to each other on or above the front and back parts, respectively, a motor, a first sensor that detects at least tensions of the first and third wires, and a control circuit. The control circuit controls the motor to generate, when the first wire is broken, in the second wire, a tension less than a tension of the second wire during no break in the first wire, and to generate, when the third wire is broken, in the fourth wire, a tension less than a tension of the fourth wire during no break in the third wire.

Abstract: A desalination apparatus that includes: a water-repellent particle layer that is located below a water tank, contains water-repellent particles, and allows passage of water vapor generated by evaporation of the liquid stored in the water tank, the water tank being a space for storing the liquid; and a liquefying layer that is located below the water-repellent particle layer, and liquefies the water vapor that has passed through the water-repellent particle layer to obtain the fresh water. The water-repellent particle layer includes: a first layer that contains first water-repellent particles among the water-repellent particles, and faces the water tank; and a second layer that contains second water-repellent particles among the water-repellent particles, and is provided below the first layer. The second water-repellent particles have a larger average particle size than the first water-repellent particles.

Abstract: Unmanned aerial vehicle includes a microphone which picks up a sound emitted by a target, an actuator which extends to change a position of the microphone, and a processor. The processor obtains positional relationship information which indicates at least one of a position of the target or a distance from the unmanned aerial vehicle to the target, causes the unmanned aerial vehicle to move to a first position at which the unmanned aerial vehicle and the target have a predetermined positional relationship based on the positional relationship information, and causes actuator to extend toward the target after unmanned aerial vehicle moves to the first position.
