    摘要： Scan blocks with scan chains are used to partition and test semiconductor devices using scan groups. The partitioning of the semiconductor device enables testing of all elements within each scan block, at speed, to provide fault coverage. A challenge in scan testing is keeping the power dissipation during testing under the allowed power capabilities of the tester power supplies, as the power used during scan test is much higher than that used during functional testing. A method for estimating the power dissipation of scan blocks in a circuit during the design stage is disclosed. Using the results generated, the circuit designer divides the design into an optimum number of scan blocks for test. Thus at-speed scan of the individual or groups of scan blocks can be estimated, during design, for optimizing test time while keeping the test power within acceptable limits.

    摘要： An LED light string employs a plurality of electrical components defined by LEDs and sockets wired in block series-parallel, where the one or more series blocks, each driven at the same input voltage as the source voltage (110 VAC or 220 VAC), are coupled in parallel. The LED light string interfaces to the source voltage using a common household plug; it may also include a corresponding common, household socket, coupled in electrical parallel, to enable multiple light strings to be connected to each other from end to end. In order to directly drive a network of diodes without current-limiting circuitry, the voltage of each series block of diodes must be matched to the input source voltage. This voltage matching requirement for direct AC drive places fundamental restrictions on the number of diodes on each diode series block, depending on the types of diodes used. For the voltage to be “matched,” it is possible to employ LED assemblies of different resistance values; e.g., the LED assemblies may emit different colors or be formed with a dedicated resistor (e.g., drop down resistor) integrally formed as part of at least one of the LED assemblies.

    摘要： A fan assembly, such as a rotary axial fan assembly, is disclosed with a shroud that is adapted to be mounted proximate to a heat exchanger. The shroud is sized for conveying a flow of fluid through the heat exchanger and the shroud. A stator fan blade extends inward from the shroud for supporting a hub generally central within the shroud. A motor stator is encapsulated within the hub for receiving a fan rotor and fan blades for forcing the flow of fluid through the heat exchanger and the shroud. The hub may be formed from a thermally conductive material for transferring heat from the motor stator into the flow of fluid for dissipating the heat.

    摘要： An LED light string where the parallel connections of additional series blocks of LED lamps are added through an intermediate or junction circuit. The first half of the rectifying diode pair in the junction circuit receive the series connected LED lamps positive connection, complete the rectification of the first rectifying diode pair and couple with the parallel wires of the lighting chain, thus completing the circuit. The second diode pair contained in the junction circuit forms a second, independent circuit by coupling with the lighting chain parallel (AC) wires the join to form the series connection for the subsequent LED lamps connected in series. This circuit is completed by a subsequent junction circuit, or by the diode pair contained in or around the end plug.
