Abstract:
An EMI-resistant circuit board assembly includes a plurality of circuit boards arranged in a stack and a metal shielding frame respectively sandwiched in between each two adjacent circuit boards. One of the circuit boards has at least one high-speed device producing high-frequency noises to the ambient, which result in EMI effect. The metal shielding frame is electrically connected to the ground potential of the circuit boards and shields the high-speed device on the circuit board to guide the high-frequency noises to the ground potential.
Abstract:
The present invention provides a system for checking drivers of hardware devices of a computer (10). The system includes: a traveling module (101) for traveling a tree structure of the drivers by accessing the System Regedit of the computer through an application programming interface; a retrieving module (102) for retrieving an error code for each of the drivers and contents of an initialization file which includes information on a version of each of the drivers; and a determining module (103) for determining whether a driver is installed properly according to the corresponding error code, and for determining whether the driver has a correct version according to the contents of the initialization file. A related method is also provided.
