Abstract: A first housing and a second housing of a handheld device are capable of sliding with respect to each other such that the first and the second housings can be positioned in different using positions and thus the handheld device can be configured at corresponding using statuses. The first housing includes a first magnetic element and the second housing includes a plurality of second magnetic elements aligning along a direction. The second magnetic elements having one polarity and the second magnetic elements having another polarity are disposed alternately. When the second housing slides on the first housing to a position where the first magnetic element faces a second magnetic element with opposite polarity, the handheld device is configured at a corresponding using status.

Abstract: A handheld device includes a row of lighting elements configured at the side of its top body that faces a keypad of its bottom body for illuminating the keypad when the two bodies slide away for use. The lighting elements projects light in a direction nearly parallel with the keypad and toward the surface of the keypad, and illumination of the keypad is therefore accomplishable in various environmental conditions. The lighting elements may also be used for illuminating the keypad or displayed with different strength or bright and dark periods based on the ambient brightness, and based on the charging rate of the handheld device's rechargeable battery when the handheld device is being charged.

Abstract: The present invention provides an optical fiber connector. The optical fiber connector is used for detachably engaging to a receptacle or a repeater. The optical fiber connector comprises a plug and an optical fiber module. The plug has a first end and a second end. The optical fiber module is disposed in the plug. The optical fiber module comprises three optical fibers. The three optical fibers are separately disposed from the first end and centralizedly extended out of the second end.

Abstract: The present invention provides an optical fiber inspection device. The optical fiber inspection device is used to inspect an optical fiber. The optical fiber has a first termination and a second termination. The optical fiber inspection device includes a light emitter and an engagement portion. The first termination of the optical fiber can be detachably connected to the engagement portion so as to make the optical fiber to be coupled to the light emitted by the light emitter.
