  • Patent number: 8347371
    Abstract: A restricted web site has features that are selectively exposed to clients. A screening web site interacts with clients and collects data about the clients using passive and/or active techniques. The screening site generates a token for the client, and includes data in the token identifying the token and describing the client. The token is encoded in a cookie and saved in the client's web browser. The client subsequently provides the token to the restricted site. The restricted site validates the token to ensure that it is legitimate, has not expired, and has not been used before. The restricted site selects one or more features to provide to the client based on the data about the client in the token and/or on other information. If the client does not present a token or the token is invalid, the restricted site does not expose any features to the client.

  • Patent number: 8340131
    Abstract: A system (and a method) are disclosed for reliably disseminating a state of a node in a large network consisting of nodes with constrained resources. The system comprises a process embodied by a state machine comprised of an advertise state, a request state, and a share state. The system processes input events, mutates its internal state, and outputs side effects. The outputs from one node in the network may become inputs events to one or more other nodes in the network. Viral dissemination is an emergent behavior across the nodes in a network that all independently and continuously perform these input processings, state mutations, and output side effects.

  • Patent number: 8341745
    Abstract: The probability of a computer file being malware is inferred by iteratively propagating domain knowledge among computer files, related clients, and/or related source domains. A graph is generated to include machine nodes representing clients, file nodes representing files residing on the clients, and optionally domain nodes representing source domains hosting the files. The graph also includes edges connecting the machine nodes with the related file nodes, and optionally edges connecting the domain nodes with the related file nodes. Priors and edge potentials are set for the nodes and the edges based on related domain knowledge. The domain knowledge is iteratively propagated and aggregated among the connected nodes through exchanging messages among the connected nodes. The iteration process ends when a stopping criterion is met.

  • Patent number: 8340604
    Abstract: An RF power amplifier system comprises an amplitude control loop and a phase control loop. The amplitude control loop adjusts the supply voltage to the power amplifier based upon the amplitude correction signal indicating the amplitude difference between the amplitude of the input signal and an attenuated amplitude of the output signal. The phase control loop adjusts the phase of the input signal based upon a phase error signal indicating a phase difference between phases of the input signal and the output signal. The phase control loop may comprise one or more variable phase delays introducing a relative phase delay to allow the phase differences between the input and output signals of the PA circuit to be within a range compatible with a phase comparator generating the phase error signal, and a low frequency blocking module that removes the larger extent, lower frequency components of the phase error signal.

  • Patent number: 8341737
    Abstract: A callback component embedded on a web site determines a current location of the web site. The current location is compared to a known legitimate location of the web site to determine if the web site has been copied to a different host location. Responsive to determining that the web site has been copied to a different location, the callback component alerts a central authority that the web site may be a fraudulent web site set up to launch phishing attacks. If the central authority determines that the web site is fraudulent, the central authority alerts appropriate entities to take down the fraudulent web site. The callback component generates a visual component viewable on the web site to deter phishing attackers from removing the callback component when the web site is copied.

  • Patent number: 8340449
    Abstract: A method and system generates and compares fingerprints for videos in a video library. The video fingerprints provide a compact representation of the spatial and sequential characteristics of the video that can be used to quickly and efficiently identify video content. Because the fingerprints are based on spatial and sequential characteristics rather than exact bit sequences, visual content of videos can be effectively compared even when there are small differences between the videos in compression factors, source resolutions, start and stop times, frame rates, and so on. Comparison of video fingerprints can be used, for example, to search for and remove copyright protected videos from a video library. Further, duplicate videos can be detected and discarded in order to preserve storage space.

  • Patent number: 8341036
    Abstract: An order is placed by a purchaser at a client system and received by a server system. The server system receives purchaser information including identification of the purchaser, payment information, and shipment information from the client system. The server system then assigns a client identifier to the client system and associates the assigned client identifier with the received purchaser information. The server system sends to the client system the assigned client identifier. The client system receives and stores the assigned client identifier. In response to an order indication, the client system sends to the server system a request to purchase the identified item. The server system receives the request and combines at least one previous purchase associated with the client identifier of the client system to generate a single order for billing and shipment.

  • Patent number: 8333839
    Abstract: A vapor deposition reactor has a configuration where a substrate or a vapor deposition reactor moves in a non-contact state with each other to allow the substrate to pass by the reactor and an injection unit and an exhaust unit are installed as a basic module of the reactor for receiving a precursor or a reactant and for receiving and pumping a purge gas, respectively. With the use of a small-size inlet for the reactor, homogeneous film properties are obtained, the deposition efficiency of precursors is improved, and an amount of time required for a purge/pumping process can be reduced. In addition, since the reactor itself is configured to reflect each step of ALD, it does not need a valve. Moreover, the reactor makes it easier for users to apply remote plasma, use super high frequencies including microwave, and UV irradiation.

  • Patent number: 8334660
    Abstract: A driving circuit for regulating current in a light source using a tracking component. The tracking component detects the voltage difference between an input node in the input stage and an output node in the output stage. The input stage is connected to a current source and includes an input transistor. The output stage is connected to the light source and includes an output transistor. The tracking component generates an output that controls the input and output transistors based on the voltage difference between the input node and the output node so that the voltage at the input node tracks the voltage at the output node. By using the tracking component, the LED driver can achieve accurate current control through one output transistor instead of cascaded transistors, resulting in lower output operating voltage and reduced power dissipation of the LED driver. Further, the tracking component is intermittently operated or shared across different channels to reduce energy consumption of the LED driver.

  • Patent number: 8334662
    Abstract: An adaptive switch mode LED driver provides an intelligent approach to driving multiple strings of LEDs. The LED driver determines an optimal current level for each LED channel from a limited set of allowed currents. The LDO driver then determines a PWM duty cycle for driving the LEDs in each LED channel to provide precise brightness control over the LED channels. Beneficially, the LED driver minimizes the power dissipation in the LDO circuits driving each LED string, while also ensuring that the currents in each LED string are maintained within a limited range. A sample and hold LDO allows PWM control over extreme duty cycles with very fast dynamic response. Furthermore, fault protection circuitry ensures fault-free startup and operation of the LED driver.
