摘要： An enhanced-range beacon signal transmitted from a wireless terminal in a frequency band used by the wireless OFDM communications system for OFDM communications. The beacon may be received at each of a plurality of base stations of the wireless OFDM communications system. A location of the wireless terminal may be determined responsive to reception of the beacon signal at the plurality of base stations. In some embodiments, the beacon signal includes a narrowband beacon signal, which may be centered at a frequency offset with respect to a set of subcarriers used in the wireless OFDM communications system, for example, between adjacent subcarriers of the wireless OFDM system and/or in a guard band of the OFDM frequency band.

摘要： Compounds that are modified polysaccharides having pendant aldehyde functionalities are disclosed. Each of the aldehyde functionalities is attached through a linker to a position corresponding to a hydrogen atom of a different hydroxyl group of unmodified polysaccharide. Also disclosed is a method for introducing an amine-reactive functionality into a dextran. The method comprises (a) reacting the dextran with an alkylating agent having a functionality that reacts with an hydroxyl group of the dextran thereby forming an alkylated dextran wherein the alkylating agent has an olefin group and (b) treating the alkylated dextran to convert the olefin group to an amine-reactive functionality. A polysaccharide can be conjugated to a biomolecule by carrying out the above method and reacting the amine-reactive functionality with an amine functionality on the biomolecule to produce polysaccharide conjugated to the biomolecule.

摘要： The present invention is generally directed to a process and a system for transforming a liquid into a solid material using light energy. In particular, a solution containing a parent material in a liquid form is atomized in a reaction vessel and directed towards a substrate. The atomized liquid is exposed to light energy which causes the parent material to form a solid coating on a substrate. The light energy can be provided from one or more lamps and preferably includes ultraviolet light. Although the process of the present invention is well suited for use in many different and various applications, one exemplary application is in depositing a dielectric material on a substrate to be used in the manufacture of integrated circuit chips.
