A key structure includes a substrate, a key cover positioned on the substrate, a first fixed contact, a second fixed contact and a conductive portion. The key cover includes a first movable contact, a second movable contact and a fixed portion. The first movable contact, the second movable contact and the fixed portion are located at inner surface of the key cover. The first fixed contact, the second fixed contact and the conductive portion are electrically positioned on the substrate and correspond to the first movable contact, the second movable contact and the fixed portion. When the key cover deforms, the first movable contact and the second movable contact move toward the substrate, the second movable contact and the first movable contact electrically contact the second fixed contact and the second fixed contact to generate a first command signal and a second command signal.

A stylus retaining mechanism is configured for retaining a stylus. The stylus defines a cavity. The main body defines a receiving chamber to receive the stylus and a through hole above the receiving chamber. An elastic member is positioned at one end of the receiving chamber. A button assembly is attached in the cavity of the stylus. The button assembly includes a spring abutting the button. The through hole allows the button to partially extend through. The elastic member is compressed and abuts the stylus when the stylus is received in the receiving chamber.

A battery cover latching mechanism employed in an electronic device is used to assemble a battery cover to a housing. The battery cover latching mechanism includes a hook, a base body, a sliding element, and an operating element. The hook is mounted on the battery cover, and the base body is detachably assembled to the housing. The sliding element is detachably and slidably assembled to the base body and includes a latching block corresponding to the hook. The operating element is detachably assembled to the sliding element, and is pushed relative to the sliding element, the operating element forces the sliding element to move relative to the base body, the latching block unlocks the hook to detach the battery cover, when the latching block locks the hook, the battery cover is latched.

A touch screen device includes a circuit board, a power input port located on the circuit board, a main battery electronically connected to the power input port, and a stylus. A backup battery electronically connected to the power input port is located in the stylus. A power control unit is located on the circuit board. The power control unit detects the voltage value of the main battery, and compares the voltage value of the main battery with a predetermined voltage of the touch screen device. According to the comparative result, the power control unit switches between the main battery and the backup battery to provide power supply to the touch screen device.

A system and method for ambient monitoring temperature and humidity, includes a controller, a host and an alarm device. The controller includes a sensing module and a determining module. The sensing module senses temperature and humidity. The determining module determines whether the sensed environment temperature and humidity are abnormal according to predetermined standards, and determines howl long the environment continues to be abnormal, and outputs an abnormal signal if the abnormal environment continues to be abnormal beyond a preset time limit. The host is connected to the controller, to transmit an alarm signal according to the abnormal signal. The alarm device is connected to the host, to activate according to the alarm signal.
