  • Patent number: 7440546
    Abstract: A zone plate multilayer structure includes a substrate carrying a plurality of alternating layers respectively formed of tungsten silicide (WSi2) and silicon (Si). The alternating layers are sequentially deposited precisely controlling a thickness of each layer from a minimum thickness of a first deposited layer adjacent the substrate to a maximum thickness of a last deposited layer. The first minimum thickness layer has a selected thickness of less than or equal to 5 nm with the thickness of the alternating layers monotonically increasing to provide a zone plate multilayer structure having a thickness of greater than 12 ?m (microns). The x-rays are diffracted in Laue transmission geometry by the specific arrangement of silicon and tungsten silicide.

  • Patent number: 7282339
    Abstract: The present invention provides ligand-detection reagents, ligand analogs and methods for determining the presence of a ligand in a sample. The ligand-detection reagent comprises a ligand-binding antibody and a ligand analog to form an antibody-ligand analog complex wherein the ligand analog is covalently bonded to a reporter molecule. This complex may additionally comprise a labeling protein non-covalently bonded to the antibody to form a ternary complex wherein the labeling protein comprises a monovalent antibody fragment or a non-antibody protein that is covalently bonded to a label moiety. The reporter molecule is either quenched by the ligand-binding antibody or by the label moiety of the labeling protein, depending on the reporter molecule and the ligand-binding antibody, wherein the amount of quenching is directly related to the amount of ligand present in the sample.

  • Publication number: 20060034229
    Abstract: A wireless office communication system including a wireless internet base station (WIBS) encompassing a base station controller (BSC), a mobile switch controller (MSC), and an ethernet interface module for coupling the wireless internet base station (WIBS) to an existing internet protocol (IP) based network. A wireless office communication system can also be based on the conventional architecture comprising the base station transceiver subsystem BTS, BSC, and MSC. The WIBS or BTS is attached to a number of antennas via different and identifiable delay elements for the purpose of determining the serving antennas of mobile communication units. A location determination logic enables the system to handle handoffs between a WIBS or BTS and the external public communication system in an optimum manner.

  • Patent number: 6767993
    Abstract: The present invention relates, first, to methods for the synthesis of peptides referred to as T-1249 and T-1249-like peptides. Such methods utilize solid and liquid phase synthesis procedures to synthesize and combine groups of specific peptide fragments to yield the peptide of interest. The present invention further relates to individual peptide fragments which act as intermediates in the synthesis of the peptides on interest (e.g., T-1249). The present invention still further relates to groups of such peptide intermediate fragments which can be utilized together to produce full-length T-1249 and T-1249-like peptides.
