摘要:
An electronic device includes a first rechargeable battery, a solar cell mounted on the electronic device, a second rechargeable battery and a power management circuit. The power management circuit includes a control module, a DC/DC module, a switch and a power supply switching module. The DC/DC module is configured for converting the DC power generated by the solar cell from one voltage level to another, and activating and maintaining the activation of the control module. The switch is turned on by the control module when the control module is activated, causing the DC power from the DC/DC module to charge the second rechargeable battery. The power supply switching module is controlled by the control module to select the second rechargeable battery to power the electronic device if the voltage level of the rechargeable battery is lower than that of the second rechargeable battery.

The present invention provides a portable electronic device. The device includes a first controller, a second controller, a mode switch unit, and a main controller. The mode switch unit is for a user to operate thereby generating a mode switch instruction. The main controller is for switching a work mode according to the mode switch instruction from the mode switch unit. When the mode switch unit generates a first mode switch instruction, the device enters a common work mode whereby the main controller activates the first controller and the second controller to be on standby; and when the mode switch unit generates a second mode switch instruction, the device enters a single work mode whereby the main controller activates only one of the first controller and the second controller to be on standby.

摘要:
A robot and its component control module are disclosed. The robot includes a CPU and at least two component modules. Each component control module includes at least one actuator, at least one sensor, and a controller. The sensor is used for detecting outside information and correspondingly generating a sensing signal. The controller receives the sensing signal, controls the actuator to perform an action according to the sensing signal and sends the sensing signal to the CPU. The CPU receives the sensing signal, gets the outside information associated with the sensing signal, generates action instruction according to the outside information, and sends out the action instruction to the corresponding component control module. The controller of the corresponding component control module controls the actuator of the component control module to perform an action according to the action instruction. The robot responds quickly to outside information.
