Abstract: A portable electronic device includes a main body, a protective foldable cover, a membrane keyboard and a folding means. The protective foldable cover is attached structurally in a foldable manner to the main body and further has a foldable leaf to cover the main body. The membrane keyboard is mounted to the foldable leaf by facing the main body and is connected signally with the main body. The folding means is to provide at least one stand state for the main body to stand on the foldable leaf of the protective foldable cover and thus to present the membrane keyboard completely to a position in front of the main body.

Abstract: A ready-to-assemble casegood cabinet having pocket doors. A pocket door assembly for a ready-to-assemble casegood cabinet is also disclosed. A method of shipping a ready-to-assemble casegood cabinet, a method for assembling a ready-to-assemble casegood cabinet, and method of including a pocket door assembly in a ready-to-assemble casegood cabinet is disclosed.

Abstract: A group wiring device which has built-in light emitting means and switch mechanism coupled with wire pair receptacle thereof. The switch mechanism is normally on a “CLOSE” status but can be switched to an “OPEN” status when a plug mates with the wire pair receptacle. When the switch mechanism is “CLOSE” and a testing voltage is applied to the circuit of the light emitting means, the light emitting means will emit light for assisting wire pair identification. After the process of wire pair identification is complete, the group wiring device is deemed to be in normal operation, that is, to perform ordinary signal transmitting functions. The wire pair receptacle will then be mated with plug of network cable so as to drive the switch mechanism to become “OPEN”. Therefore, the circuit of light emitting means becomes an open circuit and provides no function at all.

Abstract: A kit for identifying fiber optic connections in a fiber optic cabling system comprises a plurality of indication optic terminators and at least one test light generator. The fiber optic system comprises a patching device, a plurality of ports furnished on the patching device, a plurality of outlets remote from the patching device, and a plurality of fiber optic cables for optically connecting the ports and the outlets. Plurality of indication optic terminators are attached onto each of the ports of the patching device. By using the test light generator to apply a test light to one of the outlets, the test light reaches a corresponding connected port of the patching device through the connection of fiber optic cable so as to make the corresponding indication optic terminator attached onto that connected port to light.

Abstract: A group wiring patching device which has built-in light emitting device and filtering device coupled with wire pair receptacle thereof. When a testing voltage is applied to the circuit of the light emitting device, the light emitting device will emit light for assisting wire pair identification. The filtering device can minimize or even eliminate loop back shorting resulted by the circuit of the connected light emitting when communication signals or low voltage signals being applied thereto. Therefore, the group wiring patching device of the present invention will be able to perform ordinary signal transmitting functions without the need to remove the light emitting device after the wire pair identification process is done.
