  • Patent number: 9887971
    Abstract: A solar power conversion device embedded security module creates trusted metering data in relation to power generated and outputs it as metering data. The security module might be constructed as an IC card using semiconductor chip fabrication and assembly techniques integral with the solar power conversion device. The device might include more than one solar cell mounted on a panel to form an array. There may be a panel management module for collating data, e.g., from multiple cells, prior to transmission over a network via the metering output. The panel management module might include a subscriber identity module and the metering data output may provide associated mobile telephone endpoint technology so that the metering data can be transmitted over an air interface.

  • Patent number: 9515522
    Abstract: A solar power conversion device has an embedded security module for creating trusted metering data in relation to power generated and for delivering it to a metering data output. The security module might for example be constructed as an integrated circuit card constructed using semiconductor chip fabrication and assembly techniques to be integral with the solar power conversion device. The device might comprise more than one solar cell mounted on a panel to form an array. There may further be provided a panel management module for collating data, for instance from multiple cells, prior to transmission over a network via the metering output. The panel management module might comprise for example a subscriber identity module and the metering data output may provide associated mobile telephone endpoint technology so that the metering data can be transmitted over an air interface.

  • Patent number: 8447359
    Abstract: A method of accomplishing a transaction by a user equipment. Transaction information is inserted in at least one data field of an information entity that associates with the transaction based on information available at the user equipment. The information entity is then transmitted from the user equipment over a wireless interface. The insertion may require authorization. The insertion may occur automatically in response to a predefined event.

  • Patent number: 8301911
    Abstract: The present invention relates to a method and a system for allowing multiple applications to manage their respective data in a device (100, 200) having a secure environment (104, 204, 211) to which access is strictly controlled. The idea of the invention is that a storage area is allocated (301) within the secure environment (104, 204, 211) of a device (100, 200). The storage area is associated (302) with an identity of an application, the associated identity is stored (303) in the secure environment (104, 204, 211) and access to the storage area is controlled (304) by verifying correspondence between the associated identity and the identity of an accessing application. This is advantageous, since it is possible for the accessing application to read, write and modify objects, such as cryptographic keys, intermediate cryptographic calculation results and passwords, in the allocated storage area.

  • Patent number: 7555284
    Abstract: A handheld device (100) is capable of communicating wirelessly with a ticket issuer (200) through a network (300) or by using a short-range link such as Bluetooth, IrDA, or the like. A ticket is purchased using a payment system (400). A user selects an image from a data store (120) and transmits it to the ticket issuer (200) along with data associated with the requested ticket. This data may comprise identification data of the user and/or the device (100), data concerning a requested validity of the ticket, data concerning the payment method and/or an optional reservation number. The ticket issuer (200) receives the request then transmits to the user a template, which the user then fills in before transmitting payment data, the completed template and the selected image from the user device (100) to the ticket issuer (200), as one or more SMS and/or MMS messages.

  • Patent number: 7263618
    Abstract: The invention relates to a method for loading a program module (L1, L2, L3) in a terminal, in which one or several programs (A, B) are running, and in which method subroutines (P1, P2, P3) are stored in said program modules (L1, L2, L3). The program modules (L1, L2, L3) are provided with first tags (T1, T2, T3), wherein to start binding, the program makes a call (7) to a subroutine (P1, P2, P3). The call (7) is supplemented with the first tags (T1, T2, T3) to select the program module (L1, L2, L3) for binding, in which the called subroutine (P1, P2, P3) is stored. The tags (T1, T2, T3) are supplemented with second tags (LT1, LT2, LT3). The call (7) is also supplemented with said second call data (PKx, PKy, PKz).
