  • Patent number: 8774223
    Abstract: Methods and apparatus are provided for inserting data symbols and pilot symbols in an OFDM (orthogonal frequency division multiplexing) transmission resource utilizing frequency hopping patterns for the data symbols and/or the pilot symbols. Data symbols and pilot symbols are allocated for down link (base station to mobile station) and up link (mobile station to bases station) transmission resources in a two-dimensional time-frequency pattern. For each antenna of a MIMO-OFDM (multiple input multiple output OFDM) communication system, pilot symbols are inserted in a scattered pattern in time-frequency and data symbols are inserted in an identical frequency-hopping pattern in time-frequency as that of other antennas.

  • Patent number: 8775324
    Abstract: The compatibility score of individuals in a social network is computed based on the compatibility of interests expressed by these individuals. The compatibility score between any two interests is calculated as the log of the estimated probability that a member of the social network will express both interests as his/her interests divided by the product of: (i) the estimated probability that a member of the social network will express the first of the two interests as his/her interest and (ii) the estimated probability that a member of the social network will express the second of the two interests as his/her interest. The compatibility score between two individuals is calculated as the sum of the compatibility scores between each interest appearing in a set of interests expressed by the first of the two individuals and each interest appearing in a set of interests expressed by the second of the two individuals.

  • Patent number: 8776240
    Abstract: A Web browser or operating system of a computer maintains a historical URL list of Web sites and Web pages that have been accessed in the past. When a prescan module of antivirus software performs an initial prescan of a computer before the antivirus software is installed, it queries this historical URL list to obtain the URLs that have been accessed in the past. These URLs are sent to a URL online query service located remotely over the Internet in order to determine the status of any of these URLs. Each URL is attempted to be matched with a database of known malicious URLs including associated malicious files and associated cleanup patterns. The query service then informs the requesting computer of the status of a particular URL sent, sending back any related malicious files and any appropriate cleanup pattern. A time period associated with each URL in the database indicates when it is known that the URL was malicious.

  • Patent number: 8775164
    Abstract: Some embodiments of an efficient string search have been presented. In one embodiment, a string of bytes representing content written in a non-delimited language is received, wherein the content has been classified into a predetermined category. In a single pass through the string of bytes, a set of N-grams is searched for simultaneously. Statistical information on occurrences of the N-grams, if any, in the string of bytes is collected. In some embodiments, a model is generated based on the statistical information, where the model is usable by a content filter to classify content.

  • Patent number: 8773974
    Abstract: Methods and systems are provided that enable an OFDM transmitter to be used for transmitting conventional OFDM or a form of transformed OFDM. A technique is provided for transforming a coded and modulated sequence of samples prior to an IFFT that enables the transformed sequence of samples to be transmitted using conventional OFDM or transformed OFDM. The selection of a transform function for transforming the coded and modulated sequence of samples may be based on optimizing the transform function for particular operating conditions between the transmitter and receiver. In some embodiments of the invention OFDM and time transformed OFDM are multiplexed in time and/or frequency in a transmission frame. In some embodiments of the invention a pilot pattern is provided in which the pilot are sent using OFDM and data is sent using OFDM and/or transformed OFDM.

  • Publication number: 20140186377
    Abstract: The present invention encompasses prostaglandin E2 (PGE2) binding proteins. The invention relates to antibodies that are wild-type, chimeric, CDR grafted and humanized. Preferred antibodies have high affinity for prostaglandin E2 and neutralize prostaglandin E2 activity in vitro and in vivo. An antibody of the invention can be a full-length antibody, or an antigen-binding portion thereof. Methods of making and methods of using the antibodies of the invention are also provided. The antibodies, or antigen-binding portions, of the invention are useful for detecting prostaglandin E2 and for inhibiting prostaglandin E2 activity, e.g., in a human subject suffering from a disorder in which prostaglandin E2 activity is detrimental.

  • Publication number: 20140184961
    Abstract: A display apparatus is disclosed which comprises a plurality of layers arranged in a light emitting direction of a light source, wherein a diaphragm layer configured to enhance an emitting brightness of the display apparatus is arranged on one of the plurality of layers. With such diaphragm layer in the display apparatus, the brightness of the display apparatus can be enhanced by the Fresnel diffraction effects of the diaphragm layer. In the 2D display, for a same brightness, the power consumption in the display apparatus may be reduced. In the 3D display, the brightness of the display apparatus may be improved and the crosstalk may be reduced.

  • Publication number: 20140185475
    Abstract: Adaptive neighboring cell measurement scaling by a wireless user equipment (UE) device. The UE may operate alternately in active and inactive states in a periodic manner according to DRX cycle timing for each of a plurality of DRX cycles. Paging messages may be checked for while in the active state during each DRX cycle. If a paging message is received, it may be decoded using a joint detection technique. The UE may adaptively determine whether or not to perform neighboring cell measurements during at least a subset of the DRX cycles, and perform neighboring cell measurements according to the adaptive determination. The adaptive determination may be based on one or more of joint detection of paging messages, one or more previous cell measurements, or an amount of motion of the UE.
