The testing apparatus includes a transferring board, at least one connecting line and at least one circuit testing board. In this case, the transferring board has at least one transferring component, which is electrically connected with the electronic device. A first end of the connecting line is electrically connected with the transferring board. The circuit testing board is electrically connected with a second end of the connecting line. The circuit testing board further has at least one testing point, which is electrically connected with the transferring component. Furthermore, a testing method for testing whether an electronic device connects correctly with a circuit board is also disclosed.
Abstract:
A self-lubricating device for supplying lubricant onto a threaded guide rod, includes a movable member disposed above the threaded guide rod, and has lower threads meshed with the threaded guide rod, and a lubricant supplier secured on the movable member, and has a nozzle extending into the movable member for supply of lubricant onto the threaded guide rod. The movable member is movable axially on the threaded guide rod in such a manner to rotate the latter upon actuated.
Abstract:
A latch structure includes a base, a connecting unit, a first elastomer, at least one hook unit and a button. In this case, the connecting unit has a first side and a second side, and the connecting unit is disposed on the base. The first elastomer has a first end and a second end. The first end connects to the connecting unit and the second end connects to the base. At least one hook unit is located at the first side of the connecting unit. The hook unit has a moving member with a hook portion and a connecting portion, and the hook portion locates in a first site. The button is located at the second side of the connecting unit. When the hook portion does not locate in the first site, the button moves toward a first direction, the button pushes the connecting unit in a second direction, and the connecting unit touches the connecting portion. Accordingly, the hook portion turns to the first site.
Abstract:
A transmitter is capable of transmitting layer 2 protocol data units (PDUs). Each PDU has an n-bit sequence number. A base sequence number VT(A) is obtained that marks a beginning sequence number of a transmitting window of the transmitter. A current sequence number VT(S) is obtained that marks a sequence number of a PDU that is next to be transmitted by the transmitter. 2n is added to a difference of the current sequence number VT(S) and the base sequence number VT(A) to yield a first value. A second value is obtained that is a modulus of the first value with 2n. A test value is then obtained that is the second value divided by a size of the transmitting window. Polling is triggered when the test value is greater than or equal to a polling value. The polling value represents a percentage of the transmitting window that has been transmitted.
Abstract:
A computer system includes a BIOS memory, an input-and-output chip, and a transmission controller having instructions stored in a portion the BIOS memory. The transmission controller is enabled to read or write the portion of BIOS memory via the input-and-output chip.
Abstract:
A received PDU is sequentially identified by an n-bit frame number (FN) and an m-bit hyper frame number (HFN), which are synchronously maintained on first and second stations. The second station determines an activation time at which a ciphering key change is to occur, and composes a security mode command that includes an identifying FN corresponding to the activation time, and x least-significant bits (LSBs) from the HFN of the identifying FN. The second station transmits the security mode command to the first station. The x LSBs contained in the security mode command enable the first station to resolve cyclical ambiguities of the identifying FN to properly construct an application time. The first station uses a first ciphering key to decrypt PDUs with FNs sequentially prior to the application time, and uses a second ciphering key to decrypt PDUs with FNs sequentially on or after the application time.
Abstract:
A peel-off device for an electronic-part delivery system has a front end portion and a recess that is indented inwardly from the front end portion, that is formed through upper and lower surfaces of the front end portion and that has a width larger than that of an electronic part of predetermined specification.
Abstract:
An apparatus for setting up a time/date of a CMOS real-time-clock within a computer system is disclosed. The computer system includes a processor, a memory, an I/O controller and a first parallel port interface. The apparatus uses the first parallel port within the system to set up the CMOS real-time-clock. The apparatus includes a reference real-time-clock for storing a reference date/time, a second parallel port interface connected to the first parallel port interface. The second parallel port interface is connected to the reference real-time-clock through a signal line. The computer system, responsive to a set-up instruction, reads the reference date/time from the reference real-time-clock and writes the reference date/time, via the I/O controller, into the CMOS real-time-clock of the computer system.
