Abstract: Systems and methods for generating a viewer-specific visitor history for a location are provided. In particular, a visitor history for a particular viewer and location can indicate a total number of users who have visited the location and can specifically identify one or more of a set of users using a facepile. The set of specifically identified users can be those users that have an associative link with the viewer and that are also associated with at least one location signal for the given location and for which the particular viewer is a permitted viewer. Thus, location signals having varying scopes of visibility information can be aggregated across a plurality of different web-services to provide a single, unified visitor history for a particular location and viewer, all while respecting user-specified visibility information.

Abstract: Embodiments of the present invention are directed toward providing ongoing authentication using biometric data. Fingerprints and/or other biometric data can be captured during the normal use of an electronic device, such as typing on a keyboard, and compared with associated reference biometrics to provide ongoing authentication to an application while the electronic device is being used. Comparison results may further be combined with additional physiological or behavioral biometrics to determine a level of authentication encompassing multiple biometric inputs and/or types.

Abstract: Various embodiments of systems and methods for reducing audio noise are disclosed. One or more sound components such as noise and network tone can be detected based on power spectrum obtained from a time-domain signal. Results of such detection can be used to make decisions in determination of an adjustment spectrum that can be applied to the power spectrum. The adjusted spectrum can be transformed back into a time-domain signal that substantially removes undesirable noise(s) and/or accounts for known sound components such as the network tone.

Abstract: A method is disclosed for discovering communication devices. The method includes broadcasting, with a first communication device, a message that can be detected by one-hop neighbors. The first communication device listens for data indicating that it has at least one two-hop neighbor, and constructs and stores a list of its one-hop and two-hop neighbors. In addition, the method may also include selecting a subset of the set of one-hop neighbors such that all of the two-hop neighbors of the first communication device can be reached by the first communication device through the subset of one-hop neighbors. Then the selected subset is stored on a list on the first communication device. Next, the first communication device broadcasts to one-hop neighbors in the selected subset, the data indicating that a one-hop neighbor is part of the selected subset. The method also allows the discovery of multi-hop neighbors by utilizing the selected subset.

Abstract: Various embodiments provide methods implemented by a requesting device and a responding device for collectively identifying one or more clusters of nearby computing devices by collaborating and sharing information. In various embodiments, the requesting device may send a distance threshold to responding devices, along with a request for grouping information about computing devices that are within the distance threshold of the responding devices. In response to receiving the request and distance threshold, each responding device may identify a number of other computing devices that are within the distance threshold and may send such information to the requesting device. The requesting device may identify one or more clusters of computing devices based on the received grouping information. By configuring responding devices to detect other computing devices within a modifiable distance threshold, the requesting device may dynamically adjust the size of identified clusters of computing devices.

Abstract: Methods and apparatuses are described for asynchronous communications in a sensor network. An indication of a receiving opportunity can be transmitted by a sensor device. The sensor device can then provide the receiving opportunity based at least in part on transmitting the indication, and disable communication resources at the sensor device for a duration of a sleep time following the receiving opportunity. An upstream node can generate information for communicating to a sensor device, receive the indication of the receiving opportunity from the sensor device, and transmit the information to the sensor device during the receiving opportunity based at least in part on receiving the indication.

Abstract: A smoking article, and a method and apparatus for producing a smoking article, in which a web material containing an adsorbent material such as activated carbon and a stabilized flavorant such as menthol is positioned adjacent an interior surface of a cigarette wrapper to deliver flavor to a smoker with minimal/insignificant migration of flavor to other parts of the smoking article or packaging. The web material may be a section that extends over only a portion of the smoking article to deliver flavor to a smoker at a specific point during smoking and if positioned at the mouth end of a smoking article will be able to deliver a flavor sensation in the final puff(s).

The emulsion can be a lipophilic compound and an emulsifier.

Abstract: A method and system for locating objects in a region having a high degree of multipath susceptibility comprises a plurality of transducers, each being a transmit or receive antenna, and being arranged about the region in known locations, to form a bistatic or multistatic radar, with some embodiments being MIMO systems. Signals transmitted by the transmit antenna(s) are received at each receive antenna and processed to form a set of channel impulse responses, or power delay profiles, representative of the region at a given time. A second set is formed at a different time, and the difference between the two sets is calculated, the difference containing information on movement within the region. The difference may be processed to localize the moving object(s) by graphical means, e.g.

Abstract: A method for processing returns from a sensor, such as a radar system, in order to identify targets is provided. The method uses a track before detect routine to integrate data from several scans in order to give better discrimination. In running the track before detect routine however a number of possible target motions are postulated and the data combined accounting for such motions. A result above a threshold may then be indicative to a target present and moving with the postulated velocity. The method gives more accurate target detection as the combined data at the correct target motion postulate is more consistent than transient noise and clutter. Once a target has been identified it is preferably removed from the data set in searching for additional targets.

Abstract: A data processing apparatus is provided with multiple devices. These devices generate parallel signals using a parallel signal protocol. A serializing circuit captures a set of parallel signals, serializes them to form a serial stream of data and transmits this serial stream of data. A deserializing circuit at a destination device receives this serial stream of data, deserializes this serial stream of data to form a second set of parallel signals corresponding to the first set of parallel signals and then applies this second set of parallel signals to the destination device.

Abstract: An acoustic correction apparatus processes a pair of left and right input signals to compensate for spatial distortion as a function of frequency when said input signals are reproduced through loudspeakers in a sound system. The sound-energy of the left and right input signals is separated and corrected in a first low-frequency range and a second high-frequency range. The resultant signals are recombined to create image-corrected audio signals having a desired sound-pressure response when reproduced by the loudspeakers in the sound system. The desired sound-pressure response creates an apparent sound image location with respect to a listener. The image-corrected signals can also be spatially-enhanced to broaden the apparent sound image and improve the low frequency characteristics of the sound when played on small loudspeakers.
