    Abstract: The embodiments include a primary frame (10) supported by two wheels (50), and connected to a towing vehicle via a tow bar (18). A cylindrical brush assembly (1) is mounted on a secondary frame (12), which rotates around the primary frame. The brush rotation is driven by an electric motor (110, 220) attached to the secondary frame. The brush rotation goes counter to the wheels' rotation. The amount of pressure between the brush and the ground is controlled by the length of a spring (23) that links the two frames. In one embodiment, the brush axis forms an angle (280) with the wheels' rotation axis, and the debris gets pushed to the side as the sweeper moves forward. In another embodiment, the brush axis is parallel to the wheels' rotation axis and the debris is driven around the brush by a wrap-around guide (100), into a hopper (140).

    Abstract: A human-powered vehicle control system includes a transmission device and a transmission operation device configured to operate the transmission device. The transmission operation device includes transmission operation controller circuitry configured to transmit a first command to an assist operation device of a human-powered vehicle through wireless communication. The transmission device includes first communicator circuitry, an actuator, and transmission controller circuitry. The first communicator circuitry is configured to receive a first shift command transmitted from the assist operation device in a case where the assist operation device receives the first command. The actuator is configured to perform a shifting action. The transmission controller circuitry is configured to control the actuator so that the actuator performs the shifting action in response to the first shift command.

    Abstract: An electrically powered bicycle equipment has an attachment/detachment seat for an electric power supply unit, and a latch assembly for holding the electric power supply unit in the seated state includes a slider having a head and a back. Either the electric power supply unit or the equipment has a sliding seat for the slider, the other one has a retaining seat for the head. The sliding seat accommodates the back of the slider, which has a peripheral groove and a ring gasket housed in the peripheral groove. The groove has two aligned sections and a deeper intermediate section between them. When the slider is in the fully advanced position, a gasket portion bridges the intermediate section between the two aligned sections, and when the slider moves back, the gasket portion can curve towards the bottom of the intermediate section of the peripheral groove.
