  • Patent number: 10931874
    Abstract: Techniques are disclosed for facilitating burst mode calibration sensing and image mode sensing. In one example, a device includes a detector array configured to detect electromagnetic radiation and provide image data frames according to a first frame rate. The device further includes a logic circuit configured to determine whether a threshold delay has elapsed. The device further includes a frame output circuit configured to: provide, based at least on the threshold delay having elapsed, the image data frames according to the first frame rate; and provide, based at least on the threshold delay not having elapsed, the image data frames according to a second frame rate lower than the first frame rate. Related methods and systems are also provided.

  • Publication number: 20210027458
    Abstract: A mobile device that includes a camera and an extended reality software application program is employed by a user in an operating environment, such as an industrial environment. One or more objects within a geofence may be identified. A device crosses within the geofence and acquires sensor data associated with an object within the geofence. The sensor data may include image data and/or audio data. The device or a server system may then determine an object identifier associated with the object based on a comparison of the sensor data with data associated with object identifiers corresponding to objects within the geofence. Based on the object identifier, data associated with the object are obtained. The data associated with the object may be presented via the device, such as an extended reality overlay over a view of the object in the device.

  • Publication number: 20200380694
    Abstract: A method of detecting an edge of a support surface in an imaging controller includes: obtaining image data captured by an image sensor and a plurality of depth measurements captured by a depth sensor, the image data and the plurality of depth measurements corresponding to an area containing the support surface; detecting preliminary edges in the image data; applying a Hough transform to the preliminary edges to determine Hough lines representing candidate edges of the support surface; segmenting the plurality of depth measurements to assign classes to each pixel, each class defined by one of a plurality of seed pixels, wherein the plurality of seed pixels are identified from the depth measurements based on the Hough lines; and detecting the edge of the support surface by selecting a class of pixels and applying a line-fitting model to the selected class to obtain an estimated edge of the support surface.

  • Patent number: 10649619
    Abstract: A system, method and architecture of using context in determining a response to user interaction with a device, such context may be context of content being output by the device, the device's context, the user's content, or some combination of contexts. In accordance with one or more embodiments, a response may comprise a menu the content of which, e.g., one or more user-selectable actions or options, can be determined based on a determined context, or contexts, or a determination may be made to provide a response other than an option menu, which determination may be made based on a determined context or combination of contexts. As yet another alternative, a determination may be made to provide a response that includes a menu, the content of which is determined based on one or more determined contexts, and another response, such as an answer identified based on one or more determined contexts.

  • Publication number: 20190361928
    Abstract: As provided herein, a list of locales of interest in a location may be sorted into one or more categories. A user performing a search for a locale of interest (e.g., a restaurant) may be identified. A local score may be assigned to the locale of interest based upon a number of local users (e.g., users residing in the location) that perform the search. A second user may be determined to be near the locale of interest. A category of interest may be determined for the second user (e.g., an interest in local non-tourist restaurants). Responsive to the category of interest corresponding to the category and the local score of the locale of interest exceeding an interest threshold, the second user may be provided with a recommendation to go to the locale of interest. The locale of interest may be a local favorite restaurant rather than a tourist trap.
