Abstract: A method and apparatus for estimating available throughput of a fixed node in a mobile node of a communication network. The communication network includes fixed nodes connected to a router connected to at least one foreign network and mobile nodes connected to the fixed nodes. A second mobile node is selected from among mobile nodes connected to a fixed node whose available throughput is estimated in a first mobile node. An idle slot interval of the second mobile node connected to the fixed node is set. A transmission probability is measured in one slot interval of the second mobile node through an average of set idle slot intervals. Transmission information of the second mobile node is acquired using the measured transmission probability. The available throughput of the fixed node is estimated using the acquired transmission information.

Abstract: A scheduling apparatus for a base transceiver system (BTS), determines a point of data transmission to mobile stations (MSs). The BTS includes buffers for storing data to be transmitted to the MSs. A scheduler determines a priority of each of the MSs taking into account a data rate determined depending on a channel condition between the BTS and the MSs, a required amount of transmission data, and an amount of data to be transmitted to the MSs, and determines an MS having the highest priority among the MSs, as a destination MS to which data is to be transmitted by the BTS. The scheduler increases the required amount of transmission data upon receipt of a retransmitted data packet, and decreases the required amount of transmission data after transmitting data to the MSs.

Abstract: An apparatus is provided for efficiently allocating a transmission period in a wireless network system. An access point (AP) transmits a PSMP frame indicating a downlink period provided to each station (STA) and a minimum amount of an uplink period allocated to each STA, and at least one sub PSMP frame indicating an uplink period additionally provided for an STA that transmitted a resource request message for remaining queued data in the uplink period indicated by the PSMP frame. If the uplink period indicated by the PSMP frame is insufficient to transmit the queued data, the STA transmits a data unit including a part of the queued data and a resource request message for the remaining queued data in the uplink period. After transmitting the resource request message, the STA receives the sub PSMP frame after the full period indicated by the sub PSMP frame, and transmits the remaining queued data to the AP in the uplink period indicted by the sub PSMP frame.

Abstract: An inspection method for a circuit substrate is disclosed, which inspects electrical properties of a circuit substrate having a multilayered structure, by controlling inspection environments so that dew forms on a surface of the circuit substrate and detecting change of states of the dew to thereby determining variation of a thermal capacity of a conductor with respect to defective contacts or vias, micro vias and a circuit pattern of an inner layer. According to this, the inspection can be performed with respect to a wide area simultaneously and therefore the inspection productivity can be improved. In addition, since the temperature of the conductive wire can be measured directly through change of the dew, the cost for the temperature measurement can be saved. Moreover, the cost for an area sensor to sense the temperature of a wide area may be reduced while improving the inspection speed.

Abstract: Disclosed herein are an apparatus and method for testing open and short circuits of conductive lines. A probe is brought into contact with one end of each of the conductive lines, AC power is applied, and the conductive lines are tested using electrical variations measured in the probe. By using a single-side probe device, it is possible to remarkably reduce the number of probes when the open or short circuit of a PCB pattern, a data transmission line or an electrical cable is tested and to remarkably reduce time or labor necessary for testing the open or short circuit. Since the measurement is performed only at one end of the conductive line to test the open or short circuit of the conductive line, it is possible to self-diagnose the open or short circuit when a single-side probe device is mounted in an input/output port of an electrical device.
