Abstract
A motorized component for a bicycle includes a motor, a power source configured to generate current for the motor, and a processor. The processor is configured to identify a state of the bicycle and, based on the identified state of the bicycle, generate an audio notification. The generation of the audio notification includes control of the current from the power source to the motor, such that a periodic current with a frequency between 20 Hz and 20 kHz is applied to the motor.
Claims20
A motorized component for a bicycle, the motorized component comprising:
- a motor;
- a power source configured to generate current for the motor;
- and
- a processor configured to:
- identify a state of the bicycle;
- and
- generate an audio notification in response to the identified state of the bicycle, the generation of the audio notification comprising control of the current from the power source to the motor, such that a periodic current with a frequency between 20 Hz and 20 kHz is applied to the motor.
A rear derailleur for a bicycle, the rear derailleur comprising:
- a motor configured to move a movable part of the rear derailleur;
- a battery configured to generate current for the motor;
- a sensor configured to measure a voltage of the battery;
- and
- a processor in communication with the sensor, the processor being configured to:
- compare the measured voltage to a predetermined threshold voltage;
- and
- based on the comparison, generate an audio notification using the motor when the measured voltage is less than the predetermined threshold voltage.
A method for generating an audio notification using a motor of a bicycle, the bicycle comprising a power source configured to generate current for the motor, the method comprising:
- identifying, by a processor, a state of the bicycle;
- and
- generating, by the motor, the audio notification based on the identified state of the bicycle, generating the audio notification comprising:
- controlling, by the processor, the current from the power source to the motor, such that a periodic current with a frequency between 20 Hz and 20 KHz is applied to the motor.
