Abstract: A fiber optic thread assembly configured with a cumulative gap for mechanical responsiveness and protection from micro-bend damage. The assembly may be incorporated into a wireline or slickline cable for obtaining fiber optic readings of enhanced accuracy during an application in a well. The gap is uniquely tailored to allow for a natural reduction during deployment of the cable into the well, thereby providing the enhanced accuracy. However, the gap is also sufficient to help avoid micro-bend damage from the resulting mechanical responsiveness, which is attained upon deployment of the cable into the well.

Abstract: Described herein are compositions composed of a radiopaque agent and a cyanoacrylate monomer. These compositions cure in situ when administered to a subject and, thus, have numerous biomedical applications. The presence of the radiopaque agent allows the practitioner to visualize the compositions during and immediately after administration to the subject. The compositions are non-toxic and shelf-stable, and can be sterilized to prevent microbial growth. The compositions can be pre-mixed prior to sale and distribution, reducing the need for special training in their use.

Abstract: Detecting material properties such reflectivity, true color and other properties of surfaces in a real world environment is described in various examples using a single hand-held device. For example, the detected material properties are calculated using a photometric stereo system which exploits known relationships between lighting conditions, surface normals, true color and image intensity. In examples, a user moves around in an environment capturing color images of surfaces in the scene from different orientations under known lighting conditions. In various examples, surfaces normals of patches of surfaces are calculated using the captured data to enable fine detail such as human hair, netting, textured surfaces to be modeled. In examples, the modeled data is used to render images depicting the scene with realism or to superimpose virtual graphics on the real world in a realistic manner.

Abstract: Techniques of introducing virtual objects into a physical environment of AR system include displacing vertices of a mesh representing the physical environment based on a live depth map. For example, an AR system generates a mesh template, i.e., an initial mesh with vertices that represents a physical environment and a depth map that indicates a geometry of real objects within the physical environment. The AR system is configured to represent the real objects in the physical environment by displacing the vertices of the mesh based on depth values of the depth map and parameter values of a pinhole camera model. The depth values may be taken from the perspective of an illumination source in the physical environment.

Abstract: A method includes receiving, by a processor, from a first server, a first plurality of frames associated with a media item. Each frame of the first plurality of frames is associated with a respective timestamp of a first plurality of timestamps generated by the first server. A second plurality of frames associated with the media item are received from a second server. The second plurality of frames are each associated with a respective timestamp of a second plurality of timestamps generated by the second server. An offset value between a first timestamp of the first plurality of timestamps and a second timestamp of the second plurality of timestamps is determined. A modified plurality of frames is generated by modifying, based on the offset value, each timestamp of a subset of the second plurality of timestamps. The modified plurality of frames is sent to the client device.

Abstract: Techniques of identifying gestures include detecting and classifying inner-wrist muscle motions at a user's wrist using micron-resolution radar sensors. For example, a user of an AR system may wear a band around their wrist. When the user makes a gesture to manipulate a virtual object in the AR system as seen in a head-mounted display (HMD), muscles and ligaments in the user's wrist make small movements on the order of 1-3 mm. The band contains a small radar device that has a transmitter and a number of receivers (e.g., three) of electromagnetic (EM) radiation on a chip (e.g., a Soli chip. This radiation reflects off the wrist muscles and ligaments and is received by the receivers on the chip in the band. The received reflected signal, or signal samples, are then sent to processing circuitry for classification to identify the wrist movement as a gesture.

Abstract: Methods, systems, and devices supporting mapping user interface (UI) states for a web document are described. A UI state mapper program may determine a set of interactable elements that are configured to cause a UI state change to a UI of the web document, such as from a configuration for the web document. The UI state mapper program may interact with the set of interactable elements of the UI. The UI state mapper program may generate sets of nodes in a graphical node representation in response to the interacting. The sets of nodes may include nodes of a first node type with a UI state change resulting from a universal resource locator (URL) change and nodes of a second node type with a UI state change resulting from a visual effect on the UI without a URL change. The UI state mapper may generate a computer readable record indicating a sequence of interactions by the UI state mapper program to generate the graphical node representation.
