  • Patent number: 8639202
    Abstract: Provided is a device and method for providing an Alternative Frequency (AF) in a wireless terminal, by which an AF channel service suitable for a user environment can be provided. To this end, the device includes a radio broadcast receiver for receiving a radio broadcast signal, and a controller for attempting an AF channel switch after an elapse of a re-try wait time which is set according to a number of recent AF channel switch failures. The controller may detect the user environment as a walking state or a driving state. If a driving state is detected, the AF channel switch is attempted immediately when receive signal quality is below a threshold, regardless of the number of recent AF channel failures. If a walking state is detected, the AF channel switch is attempted after the elapse of the wait time.

  • Patent number: 7660592
    Abstract: A method for indicating a direction of a destination in a mobile communication terminal includes: receiving network identification information from a mobile communication network that is currently accessed; reading current location and declination information corresponding to the network identification information from a mobile communication network information table; obtaining true north information by using the declination information to correct magnetic north information of a current location measured with a geomagnetic sensor; obtaining direction information of the destination from the current location information on the basis of the true north information; and displaying the direction information of the destination.

  • Patent number: 7525272
    Abstract: A control method of a sliding door of a vehicle. A first step engages a clutch of the sliding door if an obstacle is detected during manipulation of the sliding door, and waits for a sliding door manipulation signal to be input. A second step determines whether a fuel door is open. A third step determines whether the signal is input again if the fuel door is open at the second step. A fourth step disengages the clutch if the signal is input again at the third step.

  • Publication number: 20080188047
    Abstract: An electrostatic discharge protection device, and a method of fabricating the same, includes a substrate, an n-well formed in the substrate, a p-well formed on the n-well, an NMOS transistor formed on the p-well, the NMOS transistor including a gate electrode, an n+ source and an n+ drain, and a grounded p+ well pick-up formed in the p-well, wherein the n-well is connected to the n+ drain of the NMOS transistor and the n+ source is grounded. The n+ drain and the n-well are connected to decrease a voltage of a trigger and a current density of a surface of the substrate.

  • Publication number: 20020141411
    Abstract: An apparatus transmits bit-synchronized PPP frame data between N numbers of subhighways (SHWs), embodied in an access switch subsystem of a switch, and a message switch module (MSM), embodied in an Internet gateway unit implemented for switching between Internet and the switch. The apparatus comprises a line-concentrating unit for extracting and storing valid bit-synchronized PPP frame data based on the bit-synchronized PPP frame data provided thereto on time slot basis, sequentially reading out the stored valid bit-synchronized PPP frame data to thereby produce line-concentrated PPP frame data to the MSM, and a distributing unit for extracting valid PPP frame data from the line-concentrated PPP frame data, sequentially storing the extracted valid PPP frame data, concurrently reading out the stored valid PPP frame data on time slot basis and transferring the read-out valid PPP frame data through a corresponding time slot of a pertinent SHW.

  • Patent number: 5881273
    Abstract: An apparatus generates a set of a reference clock pulse and a reference frame pulse signals (RCPS and RFPS) for use in an access subsystem processor of an electronic switching system. At first, a set of a clock pulse and a frame pulse signals (CPS and FPS) generated from a processor associated with the apparatus is received and converted into a converted set of a RCPS and a RFPS. Next, a functional fail signal is obtained based on processor and signal status information from the link processor.
