  • Publication number: 20130007007
    Abstract: An approach is provided for providing a list-based interface to key-value stores. The library interface platform determines one or more key-value pairs of at least one key-value store, the one or more key-value pairs comprising one or more data entries. Next, the library interface platform causes, at least in part, an association of at least one list object with the one or more key-value pairs, one or more sub-list objects, or a combination thereof. Then, the library interface platform provides at least one interface for performing one or more operations on the at least one list object to interact with the one or more data entries, the one or more key-value pairs, the one or more sub-list objects, or a combination thereof.

  • Publication number: 20120239942
    Abstract: An example apparatus is provided that receives a pseudonym and encrypted identifier, where the pseudonym is of a user's personal data. The pseudonym has been generated using a first secret key, and the encrypted identifier has been generated by encrypting the identifier using a second secret key. The first and second secret keys are known to other user(s) authorized to access the data, and are unknown to the apparatus. The operations also include storing the personal data in a database under the pseudonym, and indexed by the encrypted identifier. The keys used for encryption and pseudorandom generation can be provided by a second apparatus (e.g. an offline security manager), which may employ a proxy re-encryption scheme to provide proper keys to the apparatus based on access policies. Only the authorized users can decrypt the keys with their private keys, thus can query the user records stored in the apparatus.

  • Publication number: 20120221600
    Abstract: An example apparatus is provided that includes a processor and a memory storing executable instructions that in response to execution by the processor cause the apparatus to at least perform a number of operations. The operations include preparing for transmission a query for feedback data regarding a decision to select one of a set of actions in a given context. The query includes an indication of the given context and a decision metric reflecting historical decisions at the apparatus to select the respective action in each of a plurality of contexts. The operations also include receiving feedback data, and calculating a recommendation value as a function thereof. In this regard, the feedback data has been calculated by one or more nodes as a function of the decision metric and another decision metric reflecting historical decisions at the respective node(s).

  • Publication number: 20110181049
    Abstract: An enhanced multi-mode power generation system harnesses solar energy, wind, and heat within a designed building or within a large enclosed area, providing an indoor system to generate electricity. Air within an enclosure is heated, either by solar energy or by use of an electrified exothermic heating material, to enhance the airflow velocity within the enclosure. A system of narrowed passageways within the enclosure further increases the airflow velocity, which enhancement may also include or be supplemented by a blower. The enhanced velocity air is passed through one or multiple-staged wind turbines to generate electrical power.

  • Publication number: 20110078775
    Abstract: An approach for providing credibility information over an ad-hoc network is described. A trust manager receives content from a transmitting node over an ad-hoc network. The trust manager retrieves one or more trust values associated with the content, the transmitting node, or both, wherein the trust values are assigned by a trust server and further adjusted based on locally collected credibility information. The trust manager conducts a local evaluation of credibility information regarding the content, the transmitting node, or both. The trust manager then generates one or more combined trust values for the content, the transmitting node, or both from the trust values and the local evaluation.

  • Publication number: 20110040975
    Abstract: A system and method is disclosed for allowing content providers to protect against widespread copying of their content, while enabling them to give their customers more freedom in the way they use the content. In accordance with one embodiment, content providers identify their content as protected by watermarking the content. Consumers use compliant devices to access protected content. All of a user's compliant devices, or all of a family's devices, can be organized into an authorized domain. This authorized domain is used by content providers to create a logical boundary in which they can allow users increased freedom to use their content.

  • Patent number: 7714996
    Abstract: Automatic optical inspection (AOI) systems are described comprising optical modules that include an illumination component and a lens array configured to direct illumination of the illumination component at a portion of a substrate. The lens array includes a Fresnel lens. The optical module includes a camera that receives reflected light resulting from an interaction of the illumination and the substrate. The camera includes a time delay integration (TDI) sensor. A telecentric imaging lens directs reflected light from the substrate to the camera. The illumination component comprises a controller coupled to multiple LED light sources, each emitting light at a different wavelength. The controller independently controls each LED light source. The illumination component includes a bright field and/or a dark field light source. The illumination component can include a front side and/or a back side light source. An optical fiber is coupled to the camera and an image processor.

  • Patent number: 7634807
    Abstract: A system and method is provided that establishes and maintains conditional trust by stating a signal of distrust from a trustee's computing platform to a trustor's computing platform. The trustor attests a trustee at a given time and also sends trust conditions to the trustee upon which the trustor trusts the trustee for some intended purpose. The trust conditions may include restrictions on hardware or software components and any status changes to the hardware or software components. The trustee then monitors the hardware and software components in relation to the trust conditions and reports distrust signals when the trustee's hardware and software configuration no longer matches the trust conditions.

  • Patent number: 7564544
    Abstract: The radiation beam of discrete light source such as LEDs is shaped by a cylindrical lens and a spherical lens to form two perpendicular narrow lines to illuminate a surface. The first line is projected onto a sample surface to improve illumination efficiency, and the second line is projected onto a pupil plane of an imaging lens to improve illumination uniformity. The layout of the LED chip is optimized to match the aspect ratio of the imaging detector. Multiple LEDs at different wavelengths are combined to improve sensitivity. The full surface of the sample is inspected through the relative motion between the sample and the optics.

  • 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.

  • Publication number: 20090049514
    Abstract: An autonomic trust management system, device or method performs trust management in an autonomic processing manner with regard to evidence collection, trust evaluation, and trust (re-)establishment and control. An autonomic trust management mechanism is embedded into a digital system, such as a device or a distributed system, for supporting trustworthy relationships among system entities. The trust management mechanism provides an autonomic adaptation of trust control modes, which include control mechanisms or operations, in order to ensure the dynamic changed trust relationships based on the feedback from a trust assessment and the adaptive trust (re-)establishment or control loops.
