Abstract: A secure multiple application card system and process is provided having secure loading and deleting capability by use of a Certification Authority and Personalization Bureau. The certification authority maintains the security of the system by requiring IC cards to be injected with its public key and a card identifier for uniquely identifying each card, by providing a personalization data block for each card, and by signing with its private key all applications to be loaded or deleted from the IC card.

Abstract: A cyanine dye having the formula 1

Abstract: Method and apparatus for securely transporting data onto an IC card. The method is used, for example, to transport data, including application programs, in a secure manner from a source located outside the IC card. At least a portion of the data is encrypted using the public key of a public/secret key pair of the intended IC card unit. The encrypted data is then sent to the IC card and the IC card verifies the key transformation unit using its unique secret key. The data can then be stored on the IC card. A copy of the public key signed by a certification authority can be used to verify that the card is authorized to be part of the overall authorized system.

Abstract: A cyanine dye having the formula wherein R1-R8 are each independently selected from a group consisting of hydrogen, C1-C6 alkyl group, and C0-C4 alkyl group having a hydrophilic substituent thereon. R11 and R12 are chosen to include a free or protected thiol, amine or hydroxyl substituent capable of reacting with a target molecule through a nucleophilic displacement mechanism. The dye is useful in labeling a variety of target molecules. Processes are described for synthesizing suitable heterocyclic and indole derivatives as precursors for the aforementioned cyanine dyes.

Abstract: A multi-application IC card which processes two or more applications using an Application Abstract Machine architecture. The AAM architecture only allows one application to be executed at a time and allows for shared processing by performing a delegation function to a second application. A data space for each application is allocated when the application is selected to be executed. The data space includes a volatile and non-volatile region. The delegation function temporarily interrupts the execution of the first application, saves the temporary data of the first application, shares any data needed with the second application and the second application is executed until the delegated task is competed. The first application then retrieves the saved data and completes its execution. A delegator stack is used to keep track of the delegator's identity when multiple delegations occur. The AAM model allows for a high level of security while transferring data between applications.

Abstract: There is provided an integrated circuit card having an associated operating mode. The integrated circuit card includes: a microprocessor; a memory coupled to the microprocessor; data stored in the memory representative of the operating mode; an operating system stored in the memory for processing selected information in a first IC card format; a shell application stored in the memory for processing the selected information in a second IC card format; and means for routing the selected information to either the operating system or the shell application responsive to the operating mode. The selected information may be a command, such as a file access command.

Abstract: A cyanine dye having the formula ##STR1## wherein R.sub.1 -R.sub.8 are each independently selected from a group consisting of hydrogen, C.sub.1 -C.sub.6 alkyl group, and C.sub.0 -C.sub.4 alkyl group having a hydrophilic substituent thereon. R.sub.11 and R.sub.12 are chosen to include a free or protected thiol, amine or hydroxyl substituent capable of reacting with a target molecule through a nucleophilic displacement mechanism. The dye is useful in labeling a variety of target molecules. Processes are described for synthesizing suitable heterocyclic and indole derivatives as precursors for the aforementioned cyanine dyes.

Abstract: A value transfer system for transferring value in transactions between electronic purses as electronic cash has a transaction failure recovery procedure whereby a pending log stores transaction messages after they are sent. On detection of an error an interface device (IFD) can issue a payment resume command to re-send the last transaction message and resume the transaction.

Abstract: A method of recording position data for measuring the position of a ground point during a survey procedure in which satellite signals are used to determine the position of an antenna on a range pole. The pole is moved through non-vertical orientations by an operator so that the antenna position is determined at various points which generally do not lie directly over the ground point. The antenna positions lie on a geometric figure, generally the surface of a sphere which is centered on the ground point and has a radius equal to the length of the pole. Characterizing the sphere by a statistical analysis of the antenna positions either in real time or during post processing, leads to an accurate measurement of the ground point position. The method is preferably enabled by an otherwise standard handheld controller device which operates as part of a roving antenna/receiver station. The satellite signals are preferably derived from the Global Positioning System although other systems may also be used.

Abstract: A garment hanger for garments and the like such as a jacket, wherein the garments are suspended from the same hanger, includes a hanger body member having arms extending in generally opposite directions and inclined with respect to each other and adapted to receive and support a jacket and the like. Pivotable rod means are mounted on the hanger body member below the arms for receiving another garment and supporting the same in spaced relation to the arms. Hook means on the hanger body member support the garment hanger on a hook receiving support. The rod means include a rod section located vertically below said arms whereby a garment may be positioned on the rod means absent displacement of a jacket supported by the arms in order to place a garment on the rod means. The arms include angled apertured mating end faces received in the body member and spring biased means are received in the body member, the hook including a portion which passes through the aperture in the end faces.
