Abstract: A method for controlling a user interface of an electronic device by providing for the benefit of a user a projection of an operating interface includes a projection device to project an operating interface on a surface and controlling a detecting device to detect control operations on the projected interface by the user. A type of the user's control operation is determined, wherein the types of the control operations can include gestures and touch operations. The electronic device is controlled to perform a function in response to the touch operation or the gesture operation.

Abstract: A battery includes a housing which is bendable. The housing includes a number of cells spaced apart from each other within the housing. The housing further includes a current collecting unit arranged within the housing and configured to electrically couple the number of cells together.

Abstract: A wearable device includes a frame and a display element is provided. The frame internally includes a sliding element. The display element is attached to the sliding element and can slide on the sliding element to be brought in front of the wearer's eye or away from the wearer's eye.

Abstract: A method for controlling a battery to charge or discharge includes detecting a usage pattern of the electronic device. The battery includes a first battery and a second battery. A state-of-charge (SOC) value of the fist battery and a SOC value of the second battery are acquired, and a processor of the electronic device can control the first battery and/or the second battery to charge and discharge the electronic device according to the usage pattern and the SOC value.

Abstract: An eye protecting method in an electronic device with storage device determines eyesight of a user who is using an electronic device, acquires light intensity of the environment, and distance of eyes of a user from the device, and applies a preferred display brightness value which is associated with the readings. The method may also cause display of warnings to the user as to eye-distance from the device and current time period spent watching the device.

Abstract: An anti-theft method includes controlling an electronic device to enter a locked status, when a charging interface of the electronic device and an I/O plug of a charger are interlocked, and a charging plug of the charger and a power outlet are interlocked. Once the electronic device is determined to be in an abnormal status according to a working status of a charging interface of the electronic device, a prompt is transmitted.

Abstract: A cylinder mechanism includes a cylinder body, a piston pole slidably installed to the cylinder body, a connecting member mounted to the piston pole away from the cylinder body, and an adjusting apparatus. The cylinder body includes two tabs protruding out from two side surfaces of the cylinder body. Each tab defines a guiding hole extending along a moving direction of the piston pole. The adjusting apparatus includes two screws and two adjusting nuts fitting about the two screws. A first end of each screw is mounted to the connecting member, and a second end of each screw is passed through the corresponding guiding hole. Each adjusting nut is connected to the second end of the corresponding screw, and the adjusting nut is configured to abut against the corresponding tab. The stroke of the piston pole is configured to adjust according as rotating the adjusting nuts.
