  • Publication number: 20020129249
    Abstract: A smartcard for use with a receiver of encrypted broadcast signals comprises a microprocessor for enabling or controlling decryption of said signals. A memory is coupled to the microprocessor. The microprocessor is adapted to enable or control the individual decryption of a plurality of such signals from respective broadcast suppliers of such signals by means of respective dynamically created zones in the memory, the dynamically created zones each being arranged to store decryption data associated with a respective one of said broadcast suppliers.

  • Patent number: 6393562
    Abstract: A receiver/decoder is programed only to accept a current entitlement control message (EMM) if it has received at least a previous EMM of a previous calendar period. When this is received, it is used to check present rights in the receiver/decoder. The invention prevents an original subscriber from fraudulently obtaining rights by disconnecting a decoder (before an authorising message can update the decoder's memory to prevent decryption) and by reconnecting the decoder (so as to be mistaken for a new subscriber legitimately having those rights).

  • Publication number: 20020048367
    Abstract: A method of transmitting and recording digital data scrambled using a control word. The scrambled data is transmitted together with the control word, and the method includes encrypting the control word with a first key. The encrypted control word is transmitted and received, and then decrypted with a decoder that includes an equivalent of the first key. The control word is re-encrypted with a second key stored in a portable support device that is received by the decoder, and the portable support device may be used with any suitable decoder. The re-encrypted control word and the scrambled digital data are recorded on a digital recording medium.

  • Patent number: 6286103
    Abstract: A method and apparatus for the transmission and reception of scrambled data is disclosed. In some embodiments, the method and apparatus includes transmitting a scrambled data stream to a decoder, sending the scrambled data stream to a portable security module inserted in the decoder, descrambling the scrambled data stream, encrypting a descrambled data stream, and using the encrypted data stream to the decoder, decrypting the encrypted data stream, and using the decrypted data stream.

  • Patent number: 5861405
    Abstract: The present invention provides 8-substituted 1,3,7-trialkylxanthines useful as A.sub.2 -selective adenosine receptor antagonists and compositions comprising such compounds. Examples of the 8-substituted 1,3,7-trialkyl xanthines include: ##STR1## In compound (a), R.sub.1, R.sub.3, and R.sub.7 are methyl and X is one to three substituents, which may be the same or different and selected from the group consisting of amino, C.sub.1 -C.sub.4 alkylcarbonylamino, carboxy C.sub.2 -C.sub.4 alkylcarbonylamino, halo, C.sub.1 -C.sub.3 alkyloxy, amino C.sub.1 -C.sub.4 alkyloxy, C.sub.1 -C.sub.4 alkyloxy carbonylamino, amino C.sub.1 -C.sub.4 alkenyloxy, isothiocyanato, and diazonium tetrafluoroborate. In compound (b), R.sub.1, R.sub.3, and R.sub.7 are methyl, R.sub..beta. is hydrogen or methyl, and X is selected from the group consisting of R, C(.dbd.O)OR, and C(.dbd.O)NH--R, wherein R is a C.sub.1 -C.sub.6 alkyl.

  • Patent number: 5620676
    Abstract: The present invention provides certain novel adenosine triphosphate (ATP) analogs, pharmaceutical compositions, and methods of using such analogs in the treatment of septic shock and other disease conditions. Examples of the ATP analogs include the mono-, di- and triphosphates of adenosines with various selected substituents at the 2, 6, 8, and 9-positions, such as alkyl, alkylphenyl, phenylalkyl, S-alkyl, S-alkenyl, S-alkylcyano, S-phenyl, S-alkylphenyl, S-alkylamino, S-alkylthioalkyl, S-alkylthiocyanato, S-alkylaminophenyl, S-alkylnitrophenyl, hydroxy, bromo, fluoro, chloro, and aminoalkylamino. The present invention also provides pharmaceutical compositions of and methods of using certain xanthine and uracil derivatives for the above disease conditions. Examples of the xanthine derivatives include xanthines having alkyl or alkyltriphosphate substituents at the 1, 3, and 7-positions. Examples of the uracil derivatives include 5-fluoro- and 5-bromo uracil triphosphates.

  • Patent number: 5280762
    Abstract: A hoist block is fixed on an inside edge of the sail and to articulated slide in order to enable a rotation in the axis of a sail boat mast groove. A drop block is on the outside edge of the sail. An associated tube or slat extends between the hoist and drop blocks in order to stiffen the sail profile. The block 2 or 9 is rigidly fixed on an articulated slider to hoist or lower the sail mechanism.

  • Patent number: 4744086
    Abstract: The invention relates to a process for the transmission in blocks of digital information words with a correction capability. This process consists of transmitting in blocks digital information words, each information word having a length of n.sub.1 bits, in which with each sequence of n.sub.2 -k (n.sub.2 >k) of consecutive information words are associated k redundancy words of n.sub.1 bits each in which, for each order i (1<i<n.sub.2), the k bits of order i of the redundancy words are redundancy bits in accordance with a Hamming code (n.sub.2 0k, k). For each set of n.sub.2 linked words, each word is transmitted while being protected by an error detecting code. Several sets of linked words can be interlaced. The words of the same order or rank of each set form a group and the groups can be formed by frames.
