  • Patent number: 11068531
    Abstract: A method, an apparatus, and a computer program product conduct online visual searches through an augmented reality (AR) device having an optical see-through head mounted display (HMD). An apparatus identifies a portion of an object in a field of view of the HMD based on user interaction with the HMD. The portion includes searchable content, such as a barcode. The user interaction may be an eye gaze or a gesture. A user interaction point in relation to the HMD screen is tracked to locate a region of the object that includes the portion and the portion is detected within the region. The apparatus captures an image of the portion. The identified portion of the object does not encompass the entirety of the object. Accordingly, the size of the image is less than the size of the object in the field of view. The apparatus transmits the image to a visual search engine.

  • Patent number: 10073518
    Abstract: An apparatus for calibrating an eye tracking system of a head mounted display displays a moving object in a scene visible through the head mounted display. The object is displayed progressively at a plurality of different points (P) at corresponding different times (T). While the object is at a first point of the plurality of different points in time, the apparatus determines whether an offset between the point P and an eye gaze point (E) satisfies a threshold. The eye-gaze point (E) corresponds to a point where a user is determined to be gazing by the eye tracking system. If the threshold is not satisfied, the apparatus performs a calibration of the eye tracking system when the object is at a second point of the plurality of different points in time. The apparatus then repeats the determining step when the object is at a third point of the plurality of different points in time.

  • Publication number: 20160127460
    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.

  • Patent number: 7122485
    Abstract: Disclosed are methods for modifying the topography of HDP CVD films by modifying the composition of the reactive mixture. The methods allow for deposition profile control independent of film deposition rate. They rely on changes in the process chemistry of the HDP CVD system, rather than hardware modifications, to modify the local deposition rates on the wafer. The invention provides methods of modifying the film profile by altering the composition of the reactive gas mixture, in particular the hydrogen content. In this manner, deposition profile and wiw uniformity are decoupled from deposition rate, and can be controlled without hardware modifications.
