Abstract: A multi-router system is described in which hardware and software components of one or more standalone routers can be partitioned into multiple logical routers. The multiple logical routers are isolated from each other in terms of routing and forwarding functions yet allow network interfaces to be shared between the logical routers. Moreover, different logical routers can share network interfaces without impacting the ability of any of the logical routers to be independently scaled to meet the bandwidth demands of the customers serviced by the logical router.

Abstract: A water-cooled mold for continuous casting includes two water-cooled wide copper plates arranged opposite to each other in a front and back direction and two water-cooled narrow copper plates arranged opposite to each other in a left and right direction. The upper portion of the cavity of the mold is a sprue area and the lower portion of the cavity is a mold cavity area. The sprue area is gradually narrowed in the casting direction and smoothly transited into the mold cavity, corresponding to the shape of a slab to be cast. The inside surfaces of the water-cooled narrow copper plates are smooth planar surfaces. A portion of the inside surface of the water-cooled wide copper plates in the sprue area is a curved surface and another portion in the mold cavity area is a planar surface. The curved surface and the planar surface portions form a continuous smooth surface.

Abstract: An automatic power-off protection apparatus includes an alternating current (AC) input; an AC output connected to the AC input via power wires that comprises a naught wire and a live wire; a switching unit for enabling and disabling a connection between the AC input and the AC output; a first pair of coupling coils for producing a first induced AC voltage; a second pair of coupling coil for a second induced AC voltage; an operational amplifier for amplifying a voltage difference between induced voltages across the first secondary coil and the second secondary coil; a first and second comparator for comparing the amplified voltage difference with a first reference voltage and a second reference voltage respectively. The automatic power-off protection apparatus cuts off the path between the AC input and the AC output when detecting current leaks.

Abstract: A humidity detection and power cut-off device for electronic equipment is provided. The device is connected between a battery (10) and a motherboard (40) of the electronic equipment and includes an auto protection device (20) and a moisture-triggered device (30). The auto protection device is connected between the battery and the power management module and is used to establish or cut off the connection between the battery and the power management module. The moisture-triggered device is used to detect the immediate ambient humidity and controls the auto protection device. If the moisture-triggered circuit detects that the immediate ambient humidity exceeds a predetermined critical humidity value, the moisture-triggered device outputs a trigger signal to the auto protection device. The trigger signal controls the auto protection circuit to cut off a connection between the battery and the power management module, thus to achieve waterproofing protecting for the electronic equipment.
