  • Publication number: 20140319063
    Abstract: A process for obtaining random copolymers from itaconic acid and/or isomers and sodium alkenyl sulfonates is by polymerization in an aqueous solution via free radicals at an acidic pH in the range from 1.0 to 3.5 and with a redox system as initiator. The copolymers can be used as calcium carbonate and calcium, strontium and barium sulfates mineral scale inhibitors and as dispersants of clays, iron oxides, calcium carbonate and strontium, barium and calcium sulfates. Random copolymers prevent and control damage in an oil reservoir, obstruction of water injection and crude oil production pipelines, and in production rigs due to mineral scale precipitation caused by high levels of salinity of the injection water and formation water. Random copolymers are tolerant to high concentrations of divalent ions, such as calcium, magnesium, strontium and barium, and can be added to the reservoir and to injection or production pipelines, treated water, sea water and water that is used as means of transportation.

    Abstract: Collagen-glycosaminoglycan membrane shell scaffold core composites for connective tissue engineering that avoids aspects of the typical tradeoff between mechanical properties (i.e. modulus, failure strength) and bioactivity (i.e., permeability and porosity) for porous tissue engineering scaffolds. The relative density of the collagen glycosaminoglycan scaffold core can be about 0.5 to about 0.95 while the membrane shell can be about 0.001 to 25 about 0.2. The core-shell composite can be tubular and the composite can have a diameter of about 1 mm to about 20 mm. The collagen glycosaminoglycan membrane shell can be perforated with about 25 to about 1000 micrometers openings or alternatively can be embossed with any range of pattern features from about 25 to about 1000 micrometers in size. The porous collagen glycosaminoglycan scaffold core can be populated with cells such as adult or embryonic stem cells, tenocytes, osteoblasts, nerve cells, cardiac cells, myocytes, fibroblasts or combinations thereof.

  • Patent number: 8494556
    Abstract: In a method for calibrating a propagation-time-based localization system in a computer-assisted manner, the position of a mobile object in a predetermined environment can be determined by detecting propagation-time-based variables of multiple base stations, wherein the propagation-time-based variable of a base station represents the propagation time of a signal between an object radio unit and the base station. The object is moved and the variables of the base stations are detected in the process at multiple measuring times. The minimum value of the variables of a base station is associated with a predefined minimum distance between the object and base station and the maximum value with a predefined maximum distance. A predefined dependence of the distances between the object and base station is scaled to the association of the minimum and maximum value. The scaled dependence is then used when determining the position of the mobile object.

  • Patent number: 8428615
    Abstract: A method and a device for determining a position of a communication apparatus is provided. To determine a position of a first apparatus a first signal is transmitted from a second apparatus to the first apparatus. A second signal is then transmitted from the first apparatus to the second apparatus as a response to the first signal, the first signal and the second signal being transmitted by way of at least two different mediums. Signal strength of the second signal received by the second apparatus and a transfer time from a first time of transmission of the first signal to a second time of receipt of the second signal are measured. The position of the first apparatus is finally calculated as a function of the measured signal strength of the received second signal and the measured transfer time.
