Abstract: Provided are a method of operating a communication system, the method comprises mapping some antennas selected from among a plurality of antennas of each of a plurality of first communication nodes and reception ports of a second communication node, combining uplink signals mapped to an identical reception port of the second communication node from among uplink signals received through the plurality of antennas, and transmitting the combined signals to the mapped reception ports of the second communication node, respectively.

Abstract: A method of operating a repeater comprises detecting a synchronization signal from a received communication signal, identifying a time division duplex (TDD) switching pattern based on a power change of the communication signal over time and switching an uplink operation and a downlink operation of the repeater based on the detected synchronization signal and the TDD switching pattern.

Abstract: A mode selection mechanism and method for a mobile terminal using a virtual mode selection dial presented on a display screen are provided. A mobile terminal having a virtual mode selection dial presented on a display includes a virtual mode selection unit for selecting one of operation modes provided by the mobile terminal and a controller for controlling functions of the operation mode selected by the virtual mode selection unit. A mode selection method for a mobile terminal includes displaying a virtual mode selection dial on a display; selecting an operation mode using the virtual mode selection dial; entering the selected operation mode; and executing a specific function associated with the operation mode in response to a user command.

Abstract: The present invention relates to an elevator system for use during an emergency. The elevator system comprises two elevator shafts constructed adjacent to each other. Each elevator shaft houses an elevator car. The elevator system operates without the use of a building's power source by incorporating a primary pulley system to move the elevator cars. Generally, the elevator cars work in tandem such that as one elevator car goes up its respective elevator shaft, the other elevator car will go down its respective elevator shaft. Moreover, a secondary pulley system and a gear system are employed to also facilitate movement of the elevator cars without using the building's power supply.

Abstract: A method of synthesizing a polymeric membrane is described in which a polymer, for example a polyvinylidene polymer or a terpolymer of ethylene, chlortrifluoroethylene and an acrylic monomer is heated and blended with a solvent. The solvent may be a high boiling latent solvent, for example butyl benzyl phthalate or tri iso nonyl trimellitate. The heated blend is shaped, which may involve casting on a supporting material such as a braided tube. Subsequently, the blend is cooled to thereby induce polymeric membrane formation on the supporting material.

Abstract: A microelectromechanical system (MEMS) sensor and method for measuring the motion of an intermediate member and a method for making the MEMS sensor. The MEMS sensor includes a substrate, a lower magnetic member disposed on the substrate, a layer disposed over the substrate, an upper magnetic member disposed at a side of the layer facing the lower magnetic member, an intermediate magnetic member magnetically levitated between the lower magnetic member and upper magnetic member; and a component measuring at least one of motion, forces acting on, and a displacement of the intermediate magnetic member.

Abstract: A method of synthesizing a polymer membrane is described in which a tetrafluoroethylene, hexafluoropropylene and vinylidene fluoride (THV) terpolymer is blended with a solvent containing polychlorotrifluoro ethylene (CTFE). The resultant blend is melted and shaped into a desired form before cooling the blend to thereby induce polymer membrane formation and process for making a membrane using THV in a NIPS process is also disclosed.

Abstract: A method of synthesizing a polymer membrane is described in which a polyvinylidene compound or an ethylene compound is blended with a solvent. The blend is applied on a supporting material, such as the outside of a hollow braid or the inside of a porous tube. Subsequently, the blend is cooled to thereby induce polymer membrane formation on the supporting material.

Abstract: A thermal clip arrangement for a roof panel system, such as a standing seam roof system, wherein the thermal clip arrangement includes a non-metallic anchor block which holds a slideable metal clip.

Abstract: Diazepam is administered intranasally in the form of specific microemulsions having advantageous properties. The microemulsions are comprised of about equal quantities of a fatty acid and water with the remainder being a hydrophilic surfactant, a polar solvent and an alcohol in a weight ratio such that alcohol is present in a greater quantity by weight than either of the other two. Nasal administration of the subject microemulsions produces a high plasma concentration of diazepam nearly as fast as intravenous administration. The present microemulsions are particularly suitable for a prompt and timely treatment of patients in the acute and/or emergency treatment of status epilepticus and other fever-induced seizures.
