  • Publication number: 20240143097
    Abstract: A display device includes a display panel including a first non-folding area, a second non-folding area, and a folding area that are arranged along a first direction, the folding area being foldable along a folding line extending along a second direction intersecting the first direction, a panel lower member disposed below the display panel, and a digitizer disposed below the panel lower member and including a base layer and sensing coils. The base layer includes a folding portion including holes overlapping the folding area of the display panel and first and second non-folding portions disposed along the first direction. The folding portion is disposed between the first and second non-folding portions. The sensing coils are disposed on the base layer, and the base layer includes a matrix including a filler and an elastomer and weaving-shaped fiber lines disposed inside the matrix and alternately arranged with each other.

  • Patent number: 8296122
    Abstract: An external connection interface emulation method and apparatus of a mobile terminal for exploiting the mobile terminal as a network adaptor of another terminal are provided. The external connection interface emulation apparatus includes a network modem for supporting communication through the mobile communication system; and a controller, which configures the network modem for operating the mobile terminal as an external network adaptor of another terminal or a communication device as it is, according to an input signal. The external connection interface emulation apparatus and method establish a communication link between a WiBro modem and a USB port at the software level making it possible to use the mobile phone as an external modem regardless of whether the WiBro modem and the USB port are compatible or not.

  • Patent number: 8259655
    Abstract: In a medium access method for contention and non-contention, a poll number for stations, or wireless terminals for communication, is managed by a base station so as to guarantee smooth traffic and improved Quality of Service (QoS). A first group of stations is provided for the non-contention, and a second group of stations is provided for the contention. The method includes (a) preparing a contention-free access message attempting access of the first group, (b) detecting a transmission time of a contention access message attempting access of the second group, (c) embedding the contention-free access message in the contention access message so as to transmit the embedded message to at least one of the first and second groups, and (d) receiving the contention access message, in which the contention-free access message is embedded, at the at least one of the first and second groups, and endowing any one of the first and second groups with a priority to attempt access to a medium in turn.

  • Patent number: 7912518
    Abstract: Provided is a power saving method for a mobile terminal, of a WiBro communication system, particularly for a standby mode. A power saving method for a mobile terminal having a modem for communicating with a base station and a host for controlling the modem, includes starting, at the mobile terminal, a timer if a resource withdrawal is determined through a negotiation with the base station; turning off power to the modem; determining whether the timer has expired; and turning on the power to the modem.

  • Publication number: 20070064606
    Abstract: A multiple network system and service providing method, wherein the multiple network system comprises a service server for providing at least one service; at least one terminal for accessing at least one network; and a manager server for recognizing a bandwidth of each service provided by the service server, a permissible bandwidth of each network, and each terminal accessing each network, and, for each service, blocking access of each terminal requesting the service to each network having a smaller permissible bandwidth than the service.

  • Publication number: 20060126497
    Abstract: A method of re-transmitting a packet of an access point (AP) in a polling-based Wireless Local Area Network (WLAN) includes: scheduling a super frame to form a first period of providing a polling message to arbitrary stations at the AP and allowing only stations receiving the polling message to get access to a medium without contention, and to form a second period of allowing the stations to get access to the medium through contention; transmitting packets stored in a first transmission queue to the corresponding stations during the first period of the super frame; and enqueuing a packet whose transmission results in failure during a first portion of a second transmission queue to re-transmit the packet whose transmission has resulted in failure during the second period upon a determination that at least one of the packets transmitted to the stations has resulted in a failure to be transmitted.

  • Publication number: 20060109833
    Abstract: A method for processing packets in a polling-based WLAN system comprises: scheduling a superframe to include a first period in which only a terminal receiving a polling message from an access point (AP) is allowed to access a medium without contention, the AP transmitting the polling message to arbitrary terminals, and a second period in which a terminal is allowed to access the medium with contention; firstly transmitting, by means of the AP, during a first sub-period in the first period of the superframe, packets stored in a queue of the AP to the arbitrary terminals; and secondly transmitting, during a second sub-period of the first period, packets that are not transmitted in time during the first sub-period in the first period but are accumulated in the queue.
