Abstract: An actuator device for a rider-posture changing apparatus of a human-powered vehicle comprises a cam follower and a cam member. The cam member is rotatable about a rotational axis. At least one of the cam follower and the cam member includes a curved surface contactable with another of the cam follower and the cam member to move the cam follower in a movement direction in response to a rotation of the cam member. The movement direction is different from a circumferential direction defined about the rotational axis. The curved surface has a curved shape in a first cross-section perpendicular to the circumferential direction.

Abstract: A control device is provided for controlling a human-powered vehicle. The control device includes an electronic controller. The human-powered vehicle includes a drive unit, a brake device, and a brake control device. The drive unit is provided with an electric motor that assists in propulsion of the human-powered vehicle. The brake device generates brake force. The brake control device controls the brake force with an electric actuator differing from the electric motor. The electronic controller is configured to control the electric motor in accordance with an actuation state of the brake control device.

Abstract: A brake device is provided to a human-powered vehicle. The brake device includes an input body, a brake, and a power converter. A driving force is input to the input body. The brake is configured to contact a rotational body of the human-powered vehicle. The power converter is configured to convert a rotational force of the input body to a force that moves the brake toward the rotational body. The power converter includes a transmission configured to change a ratio of a movement amount of the brake to an output rotational speed of the input body.

Abstract: A hub for a human-powered vehicle is provided that comprises a hub axle, a hub body, an electric power generator, and a communication device. The hub body is rotatably mounted on the hub axle about a rotational axis. The electric power generator is provided between the hub axle and the hub body. The electric power generator is configured to generate electric power by relative rotation between hub axle and the hub body. The communication device is located at least partly outside of the hub body. The communication device includes a wireless communicator configured to wirelessly communicate with an additional wireless communicator.

Abstract: A control system in accordance for a human-powered vehicle comprises a brake device configured to brake a wheel, a brake operating device operated to actuate the brake device, a first communication path configured to communicate a first actuation signal between the brake device and the brake operating device, and a second communication path configured to communicate a second actuation signal between the brake device and the brake operating device. The second communication path differs from the first communication path.

Abstract: A paper container for containing liquid such as milk and juice is disclosed. The container is formed of a thick paper provided thereon with vertical and horizontal folding lines intersecting each other at right angles. The intersecting portions of the folding lines are such formed as to be different in configurations for a predetermined length. In this way, splits and pin holes can be prevented from occurring when the thick paper is folded along the grooves to build up a container.
