  • Publication number: 20210016862
    Abstract: A power saving system for underwater vehicles includes a control system, a power unit and a battery. The control system controls the power unit to drive the underwater vehicle, and generates an output driving value. The control system includes a calculation unit, a three-axis accelerometer and gyro and an underwater vehicle weight value. The calculation unit creates a correspondent acceleration value by the output driving value and the underwater vehicle weight value. The three-axis accelerometer and gyro detects the acceleration of the underwater vehicle by every less than 0.5 second interval, and generates an acceleration value. The control system compares the correspondent acceleration value and the acceleration value to control the output driving value so as to save battery power and elongate the range of travelling of the underwater vehicles.

  • Publication number: 20180334221
    Abstract: A power generation device is installed to a bicycle crank to provide electric power to electronic products. The power generation device includes a sensor for sensing the speed of the bicycle and the crank, and generates a speed info. A micro-controller is electrically connected to the sensor and a power supply unit, and includes a transfer unit, a switch unit and an output unit. The speed info is transferred to the transfer unit and converted into transformed signals. The switch unit activates the power supply unit according to the transformed signals. When the sensor detect that the bicycle moves at inconstant speed and the crank rotates continuously, the output unit delivers electric power to the electronic products. When the sensor detects that the bicycle moves at constant speed and the crank rotates continuously, the output unit shuts off the power supply unit, and the power supply unit stores power.

  • Publication number: 20180222548
    Abstract: An electric bicycle includes two pedals, a motor, a battery providing power to the motor, a first detection member for detecting acceleration of the electric bicycle and trading acceleration of the pedals, and a controller. The controller receives the acceleration of the electric bicycle and the treading acceleration of the pedals from the first detection member, and then controls output of the motor and the battery. When the treading acceleration of the pedals is larger than the acceleration of the electric bicycle, the controller concludes that the resistance from outside to the electric bicycle increases, the controller increases output of the motor and the battery. When the treading acceleration of the pedals is smaller than the acceleration of the electric bicycle, the controller concludes that the resistance from outside to the electric bicycle decreases, the output of the motor and the battery is reduced.
