    摘要： A sensor for measuring disturbances to an electrostatic field caused by the intrusion of a charged body or a charge producing body. The sensor employs at least two probes displaced from each other which have attached beads of radioactive material to provide free ions in the vicinity of the probe. The free ions enhance the signal created by each probe when it is affected by a disturbance in the electrostatic field in which it resides. The signals thus created are conditioned for transmission to a differential amplifier which combines them and produces an output signal which represents the detection of an intruding charged body, its distance, and its characteristics. The sensor can be configured with more than two probes seeded or placed in an array and a computer for real-time selection of the two yielding optimum signals for charged body location, velocity, direction of travel, and electrostatic signature.

    摘要： A gypsum composition containing a sulfonate-containing comb-branched copolymer is disclosed. The sulfonate-containing comb-branched copolymer comprises recurring units of a polyether macromonomer, an acrylic monomer, and a sulfonate monomer. The sulfonate-containing comb-branched copolymer not only increases the fluidity of gypsum slurry but also has reduced retardation on the gypsum setting.

    摘要： A system and method for determining a threat level associated with a collection of detected objects within a geographical area of interest are disclosed. A set of formation templates representative of organizational patterns are defined. Configurations for the templates are defined. Data is collected from objects detected in the area of interest. A density image is generated based on the geographic locations of the detected objects. Sections of the density image that are too sparse to contain a formation are determined and excluded from further analysis. The density image is compared to each of the template configurations. The probability of finding points in each of the template cells for each of the template configurations is determined. The probable formation(s), if any, based on the probability of finding points in each of the template cells for each of the possible configurations of each of the possible templates is determined. If this probability is greater than the null hypothesis (no formations), probable formation(s), if any, are reported.
