    摘要: The invention provides a multiple beam antenna and a method of fabricating such an antenna. The multiple beam antenna comprises: a flexible substrate having a conductive layer; a plurality of directional antennas; and a plurality of electrical connections being routed from each of the plurality of directional antennas to at least one area of the substrate. The plurality of directional antennas and the plurality of electrical connections are formed in the conductive layer, and the flexible substrate is shaped so that the plurality of directional antennas point in prescribed directions. This provides a low cost, high functionality multiple beam antenna. The multiple beam antenna can be shaped such that the directional antennas cover a full 360° or alternatively cover any range of other angles, (e.g. 270° or 180°).

    摘要: The present invention relates to methods for isolating and storing, nucleic acid from a sample containing nucleic acid, such as a cell sample or cell lysate. The nucleic acid is isolated on a solid phase medium, which is then dried, and which can be stored efficiently, such as at room temperature, in columns, tubes, and microwell plates having a wide variety of filters and other solid phase media, for extended periods of time, including days, weeks, and months. The invention provides methods for isolating and storing nucleic acid from a sample by applying the sample to a solid phase medium, retaining the cells, lysing the cellular retentate, drying the medium and retaining the nucleic acid, storing the nucleic acid for extended periods of time at room temperature and humidity, and optionally eluting the nucleic acid. The invention provides methods for storing nucleic acid-containing samples on a wide range of solid phase media in many types of tubes, columns, or multiwell plates, many of which are commercial available.

    摘要: Previous MIMO systems have used spatially diverse antenna elements in order not to reduce the number of orthogonal channels that can be realized. The present invention recognizes that this leads to large antenna sizes, as compared to multiple beam antenna systems which use closely spaced antenna elements. In order to provide a compact antenna unit, while still allowing a MIMO system to be exploited, the present invention recognizes that polarization diversity only can be used in a MIMO system without the need for spatially diverse antenna elements. Closely spaced antenna elements are used and this enables a compact MIMO antenna unit to be provided. In addition, such MIMO systems with polarization diversity but no spatial diversity can advantageously be used in line of sight situations and also combined with multi-beam antenna systems to further increase capacity.

    摘要: A method of managing lost returns in a wellbore is disclosed. The method includes contacting a filter cake with a treating fluid to remove metallic weighting agents from the filter cake, wherein the filter cake is disposed on a face of a formation fracture in the wellbore. The method also includes contacting the filter cake with a proppant slurry, wherein the proppant slurry contacts the filter cake concurrently with the treating fluid or after the treating fluid contacts the filter cake. This method may include increasing the filter cake permeability and may utilize a barite removal agent, such as a chelation agent. At least one related wellbore management method is disclosed, which provides for creating a fracture in the wellbore and propping open the fracture to increase wellbore integrity to utilize higher weight drilling fluids and prevent fractures from forming further down the wellbore.
