Patent number: 7697562Abstract: An apparatus and method are provided for transmitting data in a station of a wireless local area network (LAN) system. In the apparatus, a data queue stores transmission data, and a data processor processes data output from the data queue. A radio frequency (RF) module up-converts a signal output from the data processor to a frequency band of the wireless LAN system, and transmits the up-converted signal as an RF signal. A scheduler performs scheduling such that a specific stepping index decreases each time a backoff time reaches ‘0’ so as to determine whether to transmit the data, and the data is transmitted when both the stepping index and the backoff time reach ‘0’. A backoff stepping generator determines an initial value of the stepping index within a predetermined range.Type: GrantFiled: June 5, 2006Date of Patent: April 13, 2010Assignees: Samsung Electronics Co., Ltd., Sungkyunkwan University Foundation for Corporate CollaborationInventors: Kyu-Ho Lee, Hee-Yong Youn

Patent number: 7331546Abstract: A micro air vehicle having a bendable wing enabling the micro air vehicle to fly. The bendable wing may be bent downwards so that the wingspan may be reduced for storing the micro air vehicle. The bendable wing may be formed from one or more layers of material, and the wing may have a camber such that a concave surface of the wing faces downward. The wing may substantially resist flexing upwards and may transfer uplift forces to a central body of the micro air vehicle. In addition, the wing may be bent severely downwards by applying a force to tips of the wing. The micro air vehicle is capable of being stored in a small cylindrical tube and may be deployed from the tube by simply releasing the micro air vehicle from the tube.Type: GrantFiled: August 25, 2006Date of Patent: February 19, 2008Assignee: University of Florida Research Foundation, Inc.Inventors: Peter Ifju, Kyu-Ho Lee, Roberto Albertani, Shawn J.
