  • Publication number: 20110317662
    Abstract: A system and method for handing off from a first network to a second network. A determination may be made as to whether an accessible base station of the second network is located in the vicinity of a user equipment based on information on a current location of the user equipment in the first network. An activation call may be generated with a first telephone number as a caller number when an accessible base station of the second network is located in the vicinity of the user equipment based on the determination result. The activation call indicates an initiation of a search for an accessible base station of the second network, and an accessible base station of the second network may be searched for when the activation call with the first telephone number is received. A handoff from the first network to the second network may then be executed when the accessible base station of the second network is located.

  • Patent number: 8064822
    Abstract: Provided is a link synchronization method for a radio frequency repeater that can perform link route switching at an accurate time point by measuring reception signal power at a predetermined period for a predetermined time duration, accumulating and comparing them with a reference level, and detecting a link termination time point. The method includes: a) setting up an initial link route; b) measuring received signal power in the initial link route; c) accumulating the reception signal power received for a predetermined time at a predetermined period, when the reception signal power is detected; d) setting up a reference level for link switching based on the accumulated reception signal power; e) detecting a link termination time point by finding an edge in a waveform of the accumulated reception signal power based on the reference level; and f) switching the current link route based on the detected link termination time point.

  • Publication number: 20110257084
    Abstract: Disclosed are exendin-3 or exendin-4 derivatives modified with biotin, a preparation method thereof and a pharmaceutical composition containing the same. More specifically, disclosed are exendin-3 or exendin-4 derivatives in which the lysine residue of exedin is modified with biotin. The disclosed exendin-3 or exendin-4 derivatives modified with biotin show biological activity similar to that of native exendin and at the same time, have increased in vivo stability and are easily absorbed through the mucosa. Thus, biotin-modified exendin-3 or exendin-4 derivatives are useful for treating diseases, which can be caused by the excessive secretion of insulin, the lowering of plasma glucose, the inhibition of gastric or intestinal motility, the inhibition of gastric or intestinal emptying or the inhibition of food intake. Particularly, the biotin-modified exendin-3 or exendin-4 derivatives are useful for the treatment of diabetes, obesity and irritable bowel syndromes.

  • Publication number: 20110239017
    Abstract: The invention concerns scheduling an application comprised of precedence constrained parallel tasks on a high-performance computer system. The computer system has a plurality of processors each enabled to operate on different voltage supply levels. First, a priority order for the tasks based on the computation and communication costs of the tasks is determined. Next, the based on the priority order of the tasks, assigning each task both a processor and a voltage level that substantially minimises energy consumption and completion time for performing that task when compared to energy consumption and completion time for performing that task on different combinations of processor and voltage level. It is an advantage of the invention that the scheduling takes account not only completion time (makespan), but also energy consumption. Aspects of the invention include a method, software, a scheduling module of a computer and a schedule.
