  • Patent number: 9016568
    Abstract: A reader device performs control to cause rates of transmission at the time of transmitting an authentication command to an IC chip included in a passport to be different from each other. Then, when the rates of transmission are caused to be different from each other, each of required times T1 and T2 required after transmitting the authentication command to the IC chip until receiving a response to the authentication command from the IC chip is measured. An operation time Tc required for execution of the authentication command in the IC chip is calculated on the basis of the required times T1 and T2 measured as described above, and, further, genuine/counterfeit judgment of the IC chip (genuine/counterfeit judgment of the passport is performed on the basis of the calculated operation time Tc.

  • Publication number: 20080027060
    Abstract: N-terminal substituted dipeptide nitriles as defined are useful as inhibitors of cysteine cathepsins, e.g. cathepsins B, K, L and S, and can be used for the treatment of cysteine cathepsin dependent diseases and conditions, including inflammation, rheumatoid arthritis, osteoarthritis, osteoporosis, tumors (especially tumor invasion and tumor metastasis), coronary disease, atherosclerosis (including atherosclerotic plaque rupture and destabilization). Particular dipeptide nitriles are compounds of formula I, or physiologically-acceptable and -cleavable esters or a salts thereof wherein: the symbols are as defined. In particular it has been found that by appropriate choice of groups R, R2, R3, R4, R5, X1, Y and L, the relative selectivity of the compounds as inhibitors of the various cysteine cathepsin types, e.g. cathepsins B, K, L and S may be altered, e.g. to obtain inhibitors which selectively inhibit a particular cathepsin type or combination of cathepsin types.
