Abstract: A method for testing a data transfer rate of an electronic device includes: receiving data transmitted from the electronic device and converting the data into test data; analyzing the test data; encoding the analyzed data to generate output data; and displaying a state of the data transfer rate based on the output data.

Abstract: A system for testing hard disks includes a hard disk testing device and a computer. The computer has a mainboard and a key-press controller. The hard disk testing device connects with the mainboard and includes: a hard disk interface configured for connecting one or more hard disks to be tested to a south bridge of the mainboard; a key-press panel configured for connecting the key-press controller of the computer, and providing a hard disk testing control interface for users; and a hard disk testing unit configured for testing the one or more hard disks.

Abstract: A contact finger test apparatus is used for testing contact fingers of a printed circuit board. The contact finger test apparatus comprises a sampler, a processor and an image-analyzer module. The sampler is for capturing an image of the contact fingers, and converting the image to the digital image. The processor is for optimizing the digital image. The image-analyzer module is for analyzing the digital image to obtain a conclusion whether there are faults in the contact fingers. A contact finger test method is also disclosed.
