Patent CA-2860959-A1 (CA)
Inventor: SAWA HARUO
IPC: B01J31/34
Filed: 2012-02-14
Abstract: Catalytic materials, particularly membranes, exhibiting high activity, high stability and low metal leaching in a variety of chemical reactions, particularly selective hydrogenations of unsaturated organic compounds, are described. These membranes are inorganic / polymeric hybrid materials in which metal complex molecular catalysts are immobilized or metal nano-particle catalysts are embedded. More specifically, the catalytic materials of the present invention exhibit higher activity and selectivity, and can be used in more extensive kinds of organic solvents than the conventional hybrid catalytic materials due to improvement in the affinity to organic solvents by containing the specific polymeric additives.

Title: Security device for pay-tv receiver decoder
Inventor: BURCKARD ANTOINE
IPC: H04N21/418
Filed: 2013-04-02
Abstract: The aim of the present invention is to ensure that a security module or conditional access module ("module") is used together with an authorised receiver/decoder to access pay TV content. The module uses a wireless transceiver to read an authorisation message from a wireless tag attached to the receiver/decoder to which it is connected. The authorisation message contains an identifier of the module and is encrypted with a system key. If the obtained identifier in the authorisation message is not the one of the security module, operation of the security module is blocked. The authorisation message is written by a communications device (located i.e. in a shop selling receiver/decoder devices) to a wireless tag attached to the receiver/decoder. Thus a sold receiver/decoder can be immediately operated together with a specific module.

Title: System and method for verifying a financial instrument
Inventor: TEMPLETON JAMES
IPC: G06Q20/40
Filed: 2001-07-10
Abstract: A system and method for verifying a financial instrument or a user's authorization to use a financial instrument. A transaction processor initiates one or more verifying transactions involving the instrument, with details that may vary from one transaction to another, such as the type of transaction (e.g., deposit, credit, debit), amount of the transaction, number of transactions, the merchant or vendor name or account for the transaction, and so on. Selected details, particularly variable ones, are saved in the system. The user accesses information regarding the transaction by accessing it on-line, via telephone, in a monthly statement, etc. The user then submits the requested details to the system through a user interface, which compares them to the stored details. If they correspond, then the user may be permitted to use the instrument (e.g., for a purchase, a fund transfer).
