A wearable system, such as a footwear system, can employ a generator. The generator can be an electro-mechanical generator with a portion that spins to create an electricity. The portion that spins can be spun in such a manner that it does not stop, but instead a next spin beings before a previous spin completes. This can repeat until the generator reaches a terminal velocity.

Provided is a charging control device including a current detector, an abnormal current determination circuit, and a charging stop circuit. The current detector is configured to detect a charging current, the abnormal current determination circuit is configured to determine whether the charging current is attenuated and/or increased in a constant voltage charging region, and to determine whether a value of the charging current per unit time is increased, and the charging stop circuit is configured to stop a constant voltage charging when the value of the charging current per unit time is increased.

A control device and a transmission system are configured to improve riding comfort of a human-powered vehicle. The control device includes an electronic controller that is configured to control a transmission device of a human-powered vehicle so that a transmission ratio at which the vehicle is started becomes equal to a designated transmission ratio. The electronic controller is configured to set the designated transmission ratio based on reference information that excludes information related to a gradient of a road surface, information related to manual operation of the transmission device, and information related to propulsion assistance of the human-powered vehicle.

A bicycle includes a frame, a charging circuit carried by the frame and configured to capture energy associated with movement of the bicycle, a power module carried by the frame, and a switch disposed electrically between the charging circuit and power module. The power module, in response to an indication that the bicycle is travelling downhill, closes the switch to enable energy transfer between the charging circuit and power module.

A solar wireless collector beacon (data hub) and associated method stores source data, received wirelessly from a data source, in a data buffer of the data hub. Sensor data is read from one or more onboard sensors of the data hub and stored as structural and/or environmental data in the data buffer. The environmental data is processed to determine an operating status of a vehicle being used with the data hub and an energy harvester of the vehicle is controlled to harvest energy from the vehicle based on the operating status. One or more of the operating status, the source data, and the environmental data is wirelessly transmitted from the data hub to an external device.

The present invention relates to a bicycle-type game simulation device comprising: a crank pedal unit; a swing footrest horizontally rotatably installed in the crank pedal unit; a swing detection means which detects a left-and-right rotation of the swing footrest and transmits a signal thereof; and a forward-and-backward rotation detection means which detects a forward/reverse rotation of a crank shaft and transmits a signal thereof, wherein a user can easily operate a behavioral motion of a player in a game with his/her foot, using the mechanism of a crank pedal of a bicycle, so that the user can perceive a good sense of reality.
