    摘要: A method for determining that all of a scrambled message has been successfully received, the scrambled message being scrambled in accordance with a scrambling key and being capable of being descrambled in accordance with a descrambling key, descrambling key generating information for generating the descrambling key being included within a control message (ECM) associated with the scrambled message. The method includes providing a scrambled message scrambled in accordance with a scrambling key, generating an unmodified ECM including descrambling key generating information for generating a descrambling key for descrambling the scrambled message, generating a first derived value based on the scrambled message using a first value derivation function, applying a first modification function to the unmodified ECM, the first modification function being based, at least in part, on the first derived value, thereby producing a modified ECM, transmitting the scrambled message and the modified ECM to a receiver, and performing, at the receiver, the following steps: generating a second derived value based on the received scrambled message using a second value derivation function, applying a second modification function to the modified ECM, the second modification function being based, at least in part, on the second derived value and being an inverse of the first modification function, thereby producing the unmodified ECM, and employing the unmodified ECM to determine that all of the message has been successfully received. Related apparatus and methods are also provided.

    摘要: Highly pure iron oxides are prepared by reaction of metallic iron, in the form of microspheroidal particles or of scraps or cuttings, with an agitated aqueous solution of a mono- or polycarboxylic acid with a pKa of 0.5 to 6 relative to the first carboxyl and capable of decomposing, by heating in air at 200 to 350 ° C., to carbon dioxide and water, using 0.03 to 1.5 moles of acid per g-atoms of iron, a water/iron weight ration of 1 to 20, and by oxidation of the ferrous carboxilate to ferric salt, with an agent selected from oxygen, mixtures containing oxygen, hydrogen peroxide, organic peroxides and hydroperoxides.

    摘要: Credit card applications typically involve the help of a third party to input the necessary data required by a credit card issuing agency. Using the present invention, a customer at a fuel dispenser can complete a credit card application and have it approved or denied in a quick and easy transaction, without the need of assistance from a third party. All required data at the fuel dispenser is entered through a user interface which includes card swipe inputs and numeric inputs through a numeric key pad. The customer does not make any alphabetical inputs on a typical keyboard because fuel dispensers do not have keyboards.

    摘要: Manufacture of TFTs corresponding to various circuits makes structures thereof complex, which involves a larger number of manufacturing steps. Such an increase in the number of the manufacturing steps leads to a higher manufacturing cost and a lower manufacturing yield. In the invention, a high concentration of impurities is doped by using as masks a tapered resist that is used for the manufacture of a tapered gate electrode, and the tapered gate electrode, and then the tapered gate electrode is etched in the perpendicular direction using the resist as a mask. A semiconductor layer under the thusly removed tapered portion of the gate electrode is doped with a low concentration of impurities.
