Abstract: A system for audience data exchange includes a first network and a second network. The first network has a first advertiser, and a first publisher. The second network is coupled to the first network, and has a second advertiser and a second publisher. The first network is a seller of data provided to the exchange system. The second network serves as a buyer of the data provided to the exchange system.

Abstract: A method of data collection for user segmentation receives an interaction of a user with a web page, and generates an ad call in response to the received interaction. The ad call is preconfigured to have an association to a first segment. The method adds the user to the first segment.

Abstract: A method of audience data exchange obtains data and provides the data to a first network within an exchange system. The first network comprises a seller of the data provided to the exchange system. The method offers for sale the data to a second network coupled to the first network. The second network serves as a first buyer of the data provided to the first network within the exchange system. The method monetizes the data without the need for participating in a particular ad call.

Abstract: A system for audience data exchange, the system includes a first network and a second network. The first network has a first data provider for collecting data and providing the data to the first network. The second network is coupled to the first network, and includes a first advertiser and a first publisher. The first network serves as a seller of the data provided by the first data provider. The second network serves as a buyer of the data provided by the first data provider. The first network compensates the first data provider.

Abstract: A computer readable medium stores a program for audience data exchange, and has sets of instructions for obtaining data and providing the data to a first network within an exchange. The first network comprises a seller of the data provided to the exchange. The instructions are for offering for sale the data to a second network coupled to the first network. The second network serves as a first buyer of the data provided to the first network. The instructions monetize the data without the need for participation in a particular ad call.

Abstract: A method of providing an opt out feature for an exchange receives a request from a first entity to join the exchange. The request includes a URL address for a web page that is configured to receive user requests to opt out of the first entity's activities. The method generates a hidden opt out segment for the first entity. The hidden opt out segment is inaccessible to entities on the exchange, including the first entity. The method grants permission to the first entity to join the exchange.

Abstract: An improved multiplex ligation-dependent amplification method is disclosed for detecting the presence of specific methylated sites in a single stranded target nucleic acid, while simultaneously, the quantification of the target nucleic acid sequence can be performed, using a plurality of probe sets of at least two probes, each of which includes a target specific region and non-complementary region containing a primer binding site. At least one of the probes further includes the sequence of one of the strands of a double stranded recognition site of a methylation sensitive restriction enzyme. The probes belonging to the same set are ligated together when hybridised to the target nucleic acid sequence, the hybrid is subjected to digestion by the methylation sensitive restriction enzyme, resulting in non-methylated recognition sites being cleaved. The probes of the uncleaved (methylated) hybrid are subsequently amplified by a suitable primer set.

Abstract: Method for measuring and/or regulating a quantity of heat contained in a fuel gas, the calorific value of the fuel gas being used as an input parameter, in which method a) the fuel gas or a part-stream of the fuel gas is guided through a volumetric meter or a mass flow meter, and the volumetric flow rate or the mass flow rate is measured, b) the speed of sound of the gas is determined under first reference conditions, c) one of the measurement variables dielectric constant, speed of sound under second reference conditions, carbon dioxide content of the fuel gas, nitrogen content of the fuel gas or density under standardized conditions is recorded; and d) the quantity of heat supplied is derived from these parameters, together with the calorific value of the fuel gas, as a measurement variable or control variable.

Abstract: Noncombustive method of measuring the calorific value of fuel gas, wherein a) the speed of sound in the gas is determined under first and under second reference conditions and one of the parameters dielectric constant, speed of sound under third reference conditions or proportion of carbon dioxide in the fuel gas is measured and b) the calorific value is derived from these three parameters, wherein the steps a) and b) are preferably preceded by a plurality of measurement cycles in which step a) is carried out using a plurality of reference gases of known calorific value, a number corresponding to the number of measurement cycles of reference signal patterns determined from the ratio of the various measurement signals measured on the reference gases are stored with assignment to the known calorific values and the signal pattern from a future measurement cycle on fuel gas of unknown calorific value is compared with the reference signal patterns so as to assign a particular calorific value.
