    摘要: Method and apparatus for increasing security of a cryptographic algorithm such as deciphering, enciphering, or a digital signature using a block type cipher such as AES implemented for instance in a “whitebox” model with the cipher key either known or unknown at the compilation time. This method is secure for use in entrusted environments, particularly for securing cryptographic keys. The look up tables characteristic of such algorithms are protected against attack here by making all such tables of the same size and indistinguishable, and further by masking the output values of such tables, typically where the tables carry out a permutation function or a logical exclusive OR operation.

    摘要: A mobile device receives signals from base stations each with multiple distributed transceivers. Each distributed transceiver may operate at different carrier frequencies. Each distributed transceiver is equipped with an independently configurable antenna array handling transmissions of the radio frequency signals to the mobile device. The mobile device generates channel measurements for the received signals, and subsequently receives a position estimate from a remote location server. The location server determines corresponding transmit diversity configurations applied to the base stations for conducting the channel measurements for the mobile device, and channel measurements at scanned locations in a location scanning region. The location server selects and utilize a signature function to calculate the position estimate for the mobile device over the transmit diversity configurations. A multi-level positioning process may be performed by adopting various signature functions, subsets of transmit configurations and/or subspaces of the location scanning region for accurate device positioning.

    摘要: For an integrated circuit (IC) that retrieves data from a memory device external to the IC, a novel memory interface module that generates a sampling clock to the memory device and samples the retrieved data is described. The memory interface module adjusts the frequency of the sampling clock and selects a sampling time for sampling the retrieved data. The memory interface includes a training module that monitors a data pin of the memory device for transitions. The training module searches and records the earliest transition and the latest transition with respect to the period of the sampling clock. The memory interface module uses the earliest transition and the latest transition to determine an interval of data uncertainty (uncertainty interval) for the data pin. The memory interface module facilitates determining a new sampling time and a new sampling clock frequency based on the uncertainty intervals.

    摘要: A system, method and computer program product for integrating, managing and coordinating activities of customers in an enterprise, across a plurality of applications, resources and touch-points. Customer data is obtained during interactions between a customer and an application, a resource or a touch-point. This data is stored in the form of virtual composite objects in cache memory, on a cluster of servers. The virtual composite objects contain customer data, policies and behaviors of the enterprise. The applications query for the virtual composite objects through the server. The server hosting the queried virtual composite object delivers the queried virtual composite object in real time to the querying application. Any updates to the virtual composite object on account of events at the applications, resources or touch-points, is carried out in real time.

    摘要: Some embodiments provide a media production application. The application receives a script of a media project and parses the script to identify (i) story sections of the media project and (ii) characters in the media project. The application automatically creates data structures for the story sections and the characters, and associations between the story sections and the characters. The application receives several different types of data related to production of a media project and automatically schedules production activities for the media project based on the different types of data. For each location at which one or more story sections will be filmed, the application receives a photo of the location. The application displays a graphical outline of the media project in which each story section is represented by a thumbnail of the photo of the location at which the story section will be filmed.

    摘要: For a document with content that has been structured into a set primitive areas, a novel method for performing contiguous selection of document content across different primitive areas in the document is disclosed. The method defines a contiguous section in the ordered list by identifying the first and last primitive elements of the contiguous selection. The first primitive element is identified as the primitive element that is closest in reading flow to a start selection point on the page, while the last primitive element is identified as the primitive element that is closest in reading flow to an end selection point on the page.

    摘要: We describe a photovoltaic (PV) panel power conditioning circuits, in particular for a PV panel with multiple sub-strings of connected solar cells. The power conditioning unit comprises a set of input power converters, one connected to each sub-string, a shared dc link to provide a common dc bus for the set of input power converters, and a common output power conversion stage coupled to the shared dc link to convert power from the shared dc link to ac power for a mains power supply output from the power conditioning unit. Local conversion of the sub-strings facilitates control of the power available from the panel and optimum energy harvesting, as well as local maximum power point tracking (MPPT) adjustment.
