Patent number: 8756463Abstract: A method and an apparatus for data management through timer compensation in a wireless communication system are provided. In the method, when a data loss occurs at a first point, whether a data loss has occurred previously and so whether a timer is being driven are determined. Whether the driven timer stops or expires at a second point is determined. When the timer stops or expires at the second point, a timer value is compensated for with consideration of a time difference between the first point and the second point. A timer for the data loss of the first point is restarted based on the compensated timer value. Therefore, a delay of a retransmission request time for lost data in an RLC (Radio Link Control) layer may be minimized.Type: GrantFiled: June 16, 2010Date of Patent: June 17, 2014Assignee: Samsung Electronics Co., Ltd.Inventor: Dong-Jun Kang

Patent number: 8535808Abstract: The present invention relates to a heat dissipation coating agent and to a heat-dissipating plate including same, which efficiently dissipate heat from the surface of a heat-dissipating plate of an electric/electronic component. Particularly, the heat dissipation coating agent, which is applied to the surface of a heat-dissipating plate of an electric/electronic component, includes infrared radiation powder and a binder, and the heat-dissipating plate is coated with a heat dissipation layer consisting of the heat dissipation coating agent. Since the heat dissipation coating agent applied to the heat-dissipating plate is highly conductive, heat is emitted from the heat-dissipating plate by conduction as well as convection. In particular, the heat dissipation coating agent, which conducts heat with high conductivity, can be applied to a heat-dissipating plate of a high-power LED light source.Type: GrantFiled: December 7, 2011Date of Patent: September 17, 2013Assignee: Korea Electrotechnology Research InstituteInventors: Hyo-yul Park, Myeong-sang Ahn, Dong-jun Kang, Dae-young Jung

Patent number: 8446908Abstract: An apparatus and method for reordering data packets in a communication system are provided. The method includes detecting that a first time value of a timer used for reordering data packets needs to be set when a missing data packet occurs in receiving data packets, and, when the timer restarts, setting the first time value to a time value determined by compensating for a second time value which is used when the timer starts. The timer starts when a first Transmission Sequence Number (TSN) of a received data packet is greater than a TSN of a data packet which is expected to be received immediately after data packets received already and when the timer is not in an active state. The timer expires at a point of time when the second time value lapses. The timer stops when a data packet with the same TSN as the first TSN is sent as a reassembly entity before the expiring of the timer.Type: GrantFiled: January 11, 2011Date of Patent: May 21, 2013Assignee: Samsung Electronics Co., Ltd.Inventor: Dong-Jun Kang
