Abstract: Provided is a walking assist device capable of changing a battery to be used without decreasing a capability to assist walking A walking assist device comprises a leg attachment, a battery, and a controller. The leg attachment has an actuator for applying torque on a joint of one leg of a user. The battery supplies electric power to the actuator. The battery (a first battery) is configured by a plurality of battery cells being connected. A battery in which at least one battery cell is electrically separated from the first battery corresponds to a second battery. The controller changes a power source of the actuator from the first battery to the second battery while the other leg is making contact with ground.

Abstract: A walking assist device which allays uneasiness felt by a user when a wearable device actively applies torque to a leg. A walking assist device comprises a controller, a headphone and a wearable device attached to left and right legs. The wearable device has a sensor that detects motion of the user's leg and a motor that applies torque to a joint of the user's leg. The controller controls the wearable device such that the joint angle of the user follows a target pattern which represents time-dependent changes of a target joint angle. The controller specifies a change timing at which a time-dependent change of the target joint angle in the target pattern meets a predetermined condition, and informs the user, before the specified change timing, that the change timing is arriving. The uneasiness felt by the user when an actuator actively applies torque to the leg joint is allayed by informing the user of the motion before the actuator performs that motion.

Abstract: The invention provides an overload detector with a simplified system configuration to be applied to a railway car having a connecting bogie. A connecting bogie 52 (two axle bogie) having front and rear wheels 52C and 52D are disposed to extend between a first car C1 and a second car C2. The front and rear cars C1 and C2 are supported via air springs 52A and 52B on the connecting bogie 52. The other end of the car C1 is supported via air springs 51A and 51B on a bogie 51 (two axle bogie) having front and rear wheels 51C and 51D. The other end of the car C2 is supported via air springs 53A and 53B on a bogie 53 (two axle bogie) having front and rear wheels 53C and 53D. Pneumoelectric converters 41 and 42 are disposed along paths of pneumatic pipings 21 and 22, and the inner pressure of air springs 51A and 51B is converted into an inner pressure signal AS1, and the inner pressure PAS2 of the air springs 52A and 52B is converted into an inner pressure signal AS2.

Abstract: In a magnetic field generating device for an ESR system in which a pair of permanent magents are respectively attached to opposing surfaces of a pair of stationary yokes arranged in opposite and spaced apart relationship with each other and a continuously varying magnetic field is caused to generate in a space between the opposing permanent magnets, a plurality of movable yokes for continuously changing the distance between the stationary yokes are arranged to at least one of the pair of stationary yokes so that they are moved individually thereby enabling the magnetic resistance of a magnetic path formed by the permanent magnets, stationary yokes and movable yokes to vary continuously. The device of this invention can vary the magnetic field intensity continuously and finely at high accuracy and can be used at a reduced cost and size with improved operationability in ESR system.
