  • Publication number: 20150278387
    Abstract: Techniques are provided that include obtaining a Document Object Model of an HTML document, such as a web page of a publisher. Elements of the Document object model may be identified that are associated with native advertisement placement candidate containers. Based at least in part on analysis associated with the Document Object Model, and utilizing at least some of the identified elements, one or more native advertisement placement candidate containers may be determined. Some techniques may utilize, in the analysis, identification of one or more secondary source HTML documents associated with a primary HTML document, and may identify, within the secondary source HTML document(s), content associated with native advertisement placement candidate containers of the primary HTML document(s).

Elements of the Document object model may be identified that are associated with native advertisement placement candidate containers. Based at least in part on analysis associated with the Document Object Model, and utilizing at least some of the identified elements, one or more native advertisement placement candidate containers may be determined. With some techniques, the analysis includes identifying a deepest set of nodes in the Document Object Model, corresponding to a particular tag sequence, whose cardinality is no less than a cardinality of a set of nodes in the Document Object Model, corresponding to a particular tag sequence, corresponding to the identified elements. Some techniques may utilize XPaths in the analysis.

  • Publication number: 20150278883
    Abstract: Techniques are provided that include obtaining a Document Object Model of an HTML document. A configuration XPath is obtained identifying, as of a configuration time, a node within the Document Object Model as a native advertisement placement candidate container. Additional information is obtained regarding native advertisement placement candidate containers within the Document Object Model, and an injection XPath, identifying a node within the Document Object Model as a native advertisement placement candidate container, is generated at an injection time, subsequent to the configuration time, based on the configuration XPath and the additional information. The additional information may include information regarding at least one of a title element, description element and image element identified by a user as being associated with native advertisement placement candidate containers. Generating the injection XPath may include removing a numerical identifier from one or more tags of the configuration XPath.

  • Publication number: 20150116568
    Abstract: A method of operating an image-sensing device includes detecting a trigger. The method also includes, in response to detecting the trigger, changing an operating mode of the image-sensing device from a first operating mode having a first spatial resolution and a first temporal resolution to a second operating mode having a second spatial resolution and a second temporal resolution. The second spatial resolution may be lower than the first spatial resolution and the second temporal resolution may be higher than the first temporal resolution. The method may also include capturing video data in the second operating mode, the video data having the second spatial resolution and the second temporal resolution.

  • Patent number: 8983893
    Abstract: In one embodiment, a dynamic graph having a plurality of nodes is modeled with a Binary Decision Diagram (BDD). Each pair of nodes in the dynamic graph is modeled using a characteristic function, g({right arrow over (t)};{right arrow over (a)};{right arrow over (b)}), where: {right arrow over (t)} denotes a time; {right arrow over (a)} denotes a first node identifier; {right arrow over (b)} denotes a second node identifier; and g evaluates to 1 (or TRUE) if and only if an edge exists and connects nodes {right arrow over (a)} and {right arrow over (b)} at time {right arrow over (t)}. The BDD is a combination of all the characteristic functions corresponding to all unique pairs of nodes in the dynamic graph.

  • Publication number: 20150073230
    Abstract: A device configured to monitor blood pressure includes an audio sensor, an optical sensor, and a processing device. The audio sensor is configured to generate an audio data signal representing a heartbeat of a subject over time. The optical sensor is configured to generate an optical data signal representing blood volume within a blood vessel of the subject over time. The processing device is configured to calculate a pulse wave transit time (PWTT) based on the audio data signal and the optical data signal. The processing device is also configured to calculate a blood pressure of the subject based on the PWTT.

  • Patent number: 8909592
    Abstract: In particular embodiments, a method includes accessing a first binary decision diagram (BDD) representing a data stream from a first sensor and a second BDD representing a data stream from a second sensor, determining whether the first sensor data and the second sensor data correlate by: constructing a third BDD by performing an OR operation between the first and second BDDs, determining sizes of the first, second, and third BDDs, and comparing the third size to the sum of the first size and the second size; where the degree that the first sensor data and the second sensor data correlate is indicated by the amount that the third size is less than the sum of the first size and the second size.

  • Patent number: 8880443
    Abstract: In one embodiment, a first computing device selects k first variable orders for a Binary Decision Diagram (BDD) representing a function having n variables, where n?4 and k?2. The first computing device distributes the k first variable orders among a plurality of second computing devices. For each of the k first variable orders distributed to one of the second computing devices, the first computing device receives, from the one second computing device, a local best variable order among the first variable order and one or more second variable orders derived from the first variable order. The first computing device determines a global best variable order for the BDD among all local best variable orders received from the second computing devices.
