Abstract:
A method for preventing battery from expanding is applied to awake an embedded controller to measure variations of a temperature and a storage capacity of a battery module of an electric device at a preset frequency to timely control the battery module to discharge when the electric device is in an off-state, so as to prevent the battery module from expanding and deforming.
Abstract:
A power supply and a power control method thereof are provided. The power supply is adapted to be coupled to a load. The power supply includes a battery, an amplifying circuit, and a control circuit. The amplifying circuit receives a load voltage from an output end of the power supply. The amplifying circuit receives a battery voltage from an output end of the battery. When the load is coupled to the output end of the power supply, the amplifying circuit provides a first output voltage according to a voltage difference between the load voltage and the battery voltage. The control circuit controls the battery according to the first output voltage in providing a second output voltage, such that the load is charged at the second output voltage.
Abstract:
An electronic device including a control unit, an embedded controller and a battery module is provided. During a booting procedure of the electronic device, the embedded controller reads a reported battery capacity and a battery temperature of the battery module. The embedded controller determines whether the reported battery capacity is lower than a minimum capacity, and further determines whether the battery temperature is lower than a minimum temperature when the reported battery capacity is lower than the minimum capacity. When the reported capacity is lower than the minimum capacity and the battery temperature is also lower than the minimum temperature, the embedded controller generates a fake battery capacity, according to which an operating system of the electronic device performs various operations. In this application, the battery module of the electronic device remains working even when the electronic device is in a low-temperature and low-battery activation environment.
Abstract:
An antenna system having an automatically adjustable directional antenna structure and a method for automatically adjusting a direction antenna structure are disclosed. The method includes receiving a first radiation signal, delaying the first radiation signal to obtain a first delay signal, receiving a second radiation signal, delaying the second radiation signal to obtain a second delay signal, combining the first delay signal and the second radiation signal to obtain a first combined signal, combining the first radiation signal and the second delay signal to obtain a second combined signal, detecting the power of the first combined signal to output a first amplitude, detecting the power of the second combined signal to output a second amplitude, and rotating a substrate based on the first amplitude and the second amplitude, so that a normal direction of the substrate is rotated and substantially aimed at an object.
Abstract:
A power bank charging system is provided and includes a power pin and a data transmission pin through which a charging current is provided to a power bank device, so as to increase a total charging current of the power bank device and thus shorten a charging time of the power bank device.
Abstract:
A snap-on battery includes a battery body and a fastening element, and the battery body has a guiding element disposed on a side of the battery body, and the fastening element is slidably coupled to and positioned at the guiding element, and the fastening element has a combining portion for combining an external connecting element. With the aforementioned components, the battery can be detachably snapped on a portable electronic device, and even if a user forgets to close a door with cover or secure the door with cover, the battery will be still hard to slip off the portable electronic device or damages due to falling out.
Abstract:
A case having a speaker mesh module and a manufacturing method thereof are provided. The case includes a base, a speaker mesh module and a combination member. The base is formed with a filling port and an opening in which the speaker mesh module is correspondingly placed. The speaker mesh module is formed with a buckle part and a sound output part. The combination member is secured on the base through the filling port with an injection molding means and served to cover the speaker mesh module. The combination member is formed with a combining part mutually fastened with the buckle part and a penetrated hole corresponding to the sound output part. Accordingly, the speaker mesh module is able to be sealed in the opening with a means other than adhering, thereby allowing the case to be provided with a stable and excellent waterproof performance.
