Abstract:
PURPOSE: A hybrid clustering based data aggregation method for multi-target tracking in a wireless sensor network is provided to transmit sensing information about multiple targets to a sync node through multiple backbone nodes in order to distribute workloads to the nodes. CONSTITUTION: If the calculated number of hops is more than a first reference value, a cluster head is selected from other sensor nodes which sense a target and a temporarily constructed cluster(S705). If the calculated number of hops is smaller than a first reference value and more than a second reference value, the cluster head of a predetermined corresponding cluster(S702). Target sensing information is transmitted to the cluster head so that the cluster head integrates the target sensing information of sensor nodes which construct the cluster and transmits the information to a backbone node(S706).

Abstract:
A hard disc drive is provided to effectively protect a magnetic head against ESD(Electro-Static Discharge) and EMI(Electro-Magnetic Interference) by improving the joint structure of a signal pad of a slider and a signal bonding pad of a suspension. A magnetic head(11) for recoding data on a disc or reproducing data from the disc is mounted on a slider(10). A signal pad(12) of the slider(10) is electrically connected to the magnetic head(11). A suspension(20) is joined to the slider(10). The suspension(20) has a signal bonding pad(22) electrically connected to the signal pad(12) of the slider(10). A bonding joint(30) is conductively joined to the signal pad(12) of the slider(10) and the signal bonding pad(22) of the suspension(20). An outer surface of the bonding joint(30) is round-processed.
Abstract:
An HDD(Hard Disk Drive), a screening method of the HDD, and a recording medium for recording a computer program which performs the method are provided to screen the HDD which has a probability that HDI(Head Disk Interference) occurs at more than an allowable error, through a burn-in process in more reliable way, thus a defective proportion is reduced. A predetermined parameter is measured while an FOD(Flying On Demand) voltage, with which one end of a magnetic head is protruded in a predetermined distance by thermal expansion, is applied to the magnetic head of an HDD of a test target(S10). Based on the measured parameter, FH(Flying Height) of the magnetic head for a disk is calculated(S20,S30). The calculated FH is compared with preset reference FH(S40). If the calculated FH is lower than the reference FH, the magnetic head is decided as a magnetic head having a probability of HDI which is more than an allowable error, and an HDD is screened(S60).

Abstract:
PURPOSE: A message managing apparatus for quickly viewing a new message of a mobile paging receiver and a method therefor are provided to collect messages in a specific memory region for a quick viewing of an unread message. CONSTITUTION: A controller checks whether new message data is inputted from a decoder(2a). If a new message has been received, the controller stores the new message data in a third memory region(3b). The controller drives an alarm unit to inform a user of receipt of the message(3c). The controller checks whether a read key is inputted(3d). If the read key is inputted, the controller reads data of the third memory region and displays it on a display unit(3e).

PURPOSE: A computer system is provided to increase an efficiency of a consultation and a presentation by mounting an additional output device and supporting a two-way communication to the output device. CONSTITUTION: A computer main body(1) has an input device and the first display device for displaying an image signal. A main communication unit is mounted in the computer main body(1) and transmits the image signal from the computer main body(1) to an external device. A display unit(60) has a sub communication unit for receiving the image signal from the main communication unit and the second display device for displaying the image signal received from the sub communication unit. A connection cable(95) is inserted between the main communication unit and the sub communication unit and makes a signal be transmitted to the computer main body(1) and the display unit(60) interactively. The display unit(60) has an auxiliary input device. The main communication unit is the first LVDS(Low voltage Differential Signaling) connection unit(30) for outputting a graphic signal from the computer main body(1) to the sub communication unit and receiving an input signal from the auxiliary input device. The sub communication unit is the second LVDS connection unit(90) for receiving the graphic signal from the computer main body(1), transmitting the graphic signal to the second display device, and the input signal from the auxiliary input device to the main communication unit. A converter is provided for converting the input signal from the display unit(60) and transmitting the converted signal to the computer main body(1).
