  • Publication number: 20110080184
    Abstract: The method and circuit for testing a TSV of the present invention exploit the electronic property of the TSV under test. The TSV under test is first reset to a first state, and is then sensed at only one end to determine whether the TSV under test follows the behavior of a normal TSV, wherein the reset and sense steps are performed at only one end of the TSV under test. If the TSV under test does not follow the behavior of a normal TSV, the TSV under test is determined faulty.

  • Publication number: 20110069832
    Abstract: A wireless network probe method intercepts a data packet sent from a certain station, which has established communication with an access point (AP) connected to a wireless network before a service set identifier (SSID) of the wireless network has been closed. The method further amends data in the data packet to generate two attacked data packets, transmits the two attacked data packets using a media control access (MAC) address of the certain station, to interrupt the communication between the AP and the certain station. Furthermore, the method intercepts a re-association data packet sent to the AP from the certain station, retrieves the SSID from the re-association data packet, and stores the SSID into a second station, so as to connect the second station to the wireless network.

  • Patent number: 7876699
    Abstract: A mobile station (200) communicating with an access point (100) includes an association module (202), a mode switching module (204), a verifying module (206), and a recording module (208). The association module associates with the access point via an original address and a virtual address. The mode switching module switches between an active mode and a power saving mode. The verifying module transmits a first test frame, then transmits a data acquiring frame to the access point to acquire the first test frame, presets a period of time for receiving the first test frame, and determines whether a time when the first test frame is received is after or before the preset period of time. The recording module records whether the access point supports Frame Exchange Sequence (FES) to switch between the active mode and the power saving mode according to a determined result of the verifying module.
