Abstract: A temperature measuring device is provided. The temperature measuring device measures the temperature in a combustion system, in particular for that of a combustion system of a gas turbine. The temperature measuring device is equipped with a heat absorbing element disposed in or on the combustion system, a measurement end disposed remotely from the combustion system having, disposed thereon, a temperature sensor measuring the temperature of the measurement end, a heat conducting element which connects the heat absorbing element to the measurement end in a thermally conductive manner, and a cooling device acting on the heat conducting element in a quantifiable manner for heat removal. A gas turbine having a temperature measuring device and method for directly determining the temperature in a combustion chamber are also provided.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for credit card and credit card like transaction enablers. In one aspect, a method includes receiving a credit card account associated with one or more gift card accounts, each respective gift card account associated with a respective balance; receiving notice of a transaction using the credit card account; determining whether a respective gift card account qualifies for use in the transaction; in response to determining that a respective gift card account qualifies for use in the transaction, determining whether to apply the respective balance to the transaction; in response to determining to apply the respective balance to the transaction, applying the respective balance to the transaction.
