Abstract: A mobile electronic device comprising an internal circuit and a battery compartment having an entrance and an exit. The battery compartment comprises a first conductor and a second conduct at the inner side of the battery compartment. The first conductor comprises at least two conductive contacts electrically connected to the internal circuit and having a distance from each other in the direction from the battery entrance to the battery exit so that, while a backup battery is sliding into the battery compartment from the battery entrance and pushing out a current battery through the battery exit, the first conductor may maintain electrical connection with conductive belt of the current battery and/or the backup battery. The structure of the second conductor is similar that of the first conductor and may maintain electrical connection with conductive belt of the current battery and/or the backup battery.

Abstract: A supercontinuum generation system comprises a noise-like pulse fiber laser structure, an amplification unit and a broadening medium. The noise-like pulse fiber laser structure generates at lease one noise-like pulse of the wavelength less than 1300 nm. The amplification unit includes a gain fiber with which the noise-like pulse is coupled. The broadening medium is coupled with the gain fiber. A supercontinuum is generated when the noise-like pulse is amplified by the amplification unit and broadened in spectrum by the broadening medium.

Abstract: Described are a method and a system for implementing function extension of an open platform. In the system, services that can be provided by an open platform are encapsulated and an operation interface is provided, so that plug-ins uniformly inherit the operation interface and transmit control parameters through the interface into a service entry to obtain the services. Therefore, the open platform has a simple framework and low coupling degree. Since the plug-ins are uniformly managed by a plug-in manager, the manageability and dynamic extensibility of the open platform are enhanced.

Abstract: A fiber laser having a ring resonance path comprises a pump light source, a Yb-doped optical fiber and a light modulation unit. The pump light source emits a pump light. The Yb-doped optical fiber is coupled with the pump light. The light modulation unit includes a grating pair, a diaphragm and two reflective elements. The grating pair is coupled with the pump light. The diaphragm includes an aperture. The light transmitted by the grating pair partially passes through the aperture and reaches one of the reflective elements to become a reflective light, and the reflective light passes through the aperture and is transmitted through the grating pair and the other reflective element to be coupled back with the ring resonance path.
