Abstract: A two-layer wind-guiding shroud includes a base. The interior of the base includes a first wind-guiding channel and a second wind-guiding channel longitudinally overlapped with each other. The first wind-guiding channel has a first wind entrance and a first wind exit. The second wind-guiding channel has a second wind entrance and a second wind exit. The first wind exit and the second wind exit are staggered. By this arrangement, the airflow generated by a fan can be guided into different wind-guiding channels toward different locations, thereby increasing the heat-dissipating efficiency of the fan.

Abstract: A system comprises a plurality of the hot swapping type uninterruptible power supply module and a plurality of conventional power supply. A HSUPS comprises a battery module and a controller module. A conventional power supplies is connected with an external AC power source and converts into DC voltage to provide power to the electronic system and/or to charge the HSUPS when necessary. The battery module holds the energy needed to power the electronic system during the absences of a conventional power supply and/or external AC power source. The controller module controls the operation to charge the battery, discharge the battery, switch off the HSUPS, or be standby. The controller module has the ability to detect for any failure event. The HSUPS provides power to the electronic system when the external AC power source is interrupted and when all of the conventional power supplies are removed from the system.

Abstract: A heat-dissipating assembly for a server includes a housing in which a partitioning plate and a power supply mounted on one side of the partitioning plate are provided. The power supply includes a casing and a power-supplying module received in the casing. The heat-dissipating assembly includes a fan received in the casing and located outside the power-supplying module. The partitioning plate and the casing are respectively provided with a plurality of first heat-dissipating holes and second heat-dissipating holes.

Abstract: Techniques for minimizing signal loss in transit are described. Data signals lose their strengths while traveling across conductive passages such as cooper wire, cooper strip, Printed Circuit Board (PCB), etc. There are two major factors that affect the signal loss: the distance and the speed. To minimize signal loss while maintaining higher rate data signals for I/O, substantially lower rate data signals are used in transit between two interfaces over a signal path.

Abstract: Techniques pertaining to powering multiple platforms with a minimum impact on air passage in a predefined environment are disclosed. Instead of connecting each of the platforms in a chassis to a power supply therein, the present invention uses what is referred to as cascading powering to power all platforms within minimum cable delivery. According to one embodiment of the present invention, each platform is provided with a pair of power connectors. At least one of the platforms has a power connector located towards or near a power supply so that only a short cable is needed to power the platform. The power is serially provided to an adjacent platform via a pair of corresponding connectors, each located on one of the two adjacent platforms. Such configuration is extended to the remaining platforms. As a result, all platforms are powered by the same power supply without using individual cables directly to the power supply.
