Abstract: A fatigue estimation system includes: an information output device (e.g., an imaging device) that outputs information regarding locations of body parts of a subject; and an estimation device that, based on the information output from the information output device in a predetermined time period, estimates a fatigue level of the subject accumulated in the predetermined time period by counting a specific movement that appears in response to fatigue accumulation, and outputs the estimated fatigue level.

Abstract: A bicycle motorization device is attached to a bicycle. The motorization device includes: a calculation unit configured to calculate speed of the bicycle; an estimation unit configured to estimate pedal force applied to pedals of the bicycle; an electric motor; a battery which supplies electric power to the electric motor; and a control unit configured to apply auxiliary driving force to a wheel of the bicycle by driving the electric motor based on the speed calculated and the pedal force estimated.

Abstract: A fatigue estimation system estimates the posture of a subject in a predetermined time period based on information output in the predetermined time period, determines whether the estimated posture of the subject matches a specific posture, and estimates, as the fatigue level of the subject accumulated in the predetermined time period, a calculated value obtained by a unit fatigue level being accumulated in accordance with a time period in which the estimated posture of the subject is determined to match the specific posture.

Abstract: An electric bicycle includes: an electric motor; a storage unit in which control software for controlling the electric motor is stored; a control unit configured to run the control software stored in the storage unit; and a communication interface unit to which a piece of hardware is removably and communicably connected. The control unit is configured to run an other piece of software different from the control software to control the piece of hardware which is communicably connected to the communication interface unit. The other piece of software is installed in the storage unit. Each of the control software and the other piece of software communicates using a distributed-communication protocol.
