  • Patent number: 10230460
    Abstract: An Optical Link Management Function “OLMF” for obtaining an optical power level for an optical link between a first and a second optical transformation modules. The OLMF sends a first message instructing a first unit to feed a set of optical transmissions representing at least one bit pattern. The OLMF sends a second message instructing the first optical transformation module to transmit the set of optical transmissions at optical power levels in a range. The OLMF sends a third message instructing a second unit to register successful or unsuccessful decoding of the set of optical transmissions based on the bit pattern. The OLMF receives a set of indications representing successful or unsuccessful decoding of the set of optical transmissions at the optical power levels. The OLMF finds a lowest optical power level for which an optical transmission of the set on the optical link is successfully decoded.

  • Patent number: 10175492
    Abstract: A display device system providing augmented reality (AR) and virtual reality (VR) displays in the same device and a method for switching between augmented reality and virtual reality modes in the embodiments of the device are disclosed. The system enables users to view an augmented reality setting, interact with objects, and switch to a virtual reality setting or vice versa without having to switch devices. When switching from virtual reality to augmented reality, a shuttering mechanism may open allowing the user to see the real environment within an augmented setting. Position on the user in the physical reality may be tracked relative to position of the user in the AR or VR. Some actions may be triggered based on the tracked location and orientation of the user.

  • Publication number: 20180371847
    Abstract: A joint connects casing sections of a casing string for transporting fluids and/or gases. The joint includes a first longitudinal part arranged to be at least partly overlapping a second longitudinal part or a casing section. The first longitudinal part is connected with the second longitudinal part or with the casing sections in a mounted state with the first longitudinal part adapted to move axially relative to the second longitudinal part or the casing sections in an operative state. The joint includes at least one shear member with a predefined shear value and the shear member is adapted to shear when an axial force exceeding the total shear value of the shear member is exerted, allowing a relative axial movement between the first longitudinal part and the second longitudinal part or the casing sections.

  • Publication number: 20180128977
    Abstract: A silicon photonic device comprises a silicon core having a core refractive index and a structure formed in the silicon core. The structure comprises a first refractive index variation pattern across the core in a first direction (x) and having a first modulation depth (H1), and a second refractive index variation pattern across the core in a second, orthogonal, direction (y) and having a second modulation depth (H2), less than the first modulation depth. The first refractive index variation pattern overlays the second refractive index variation pattern, forming a three-dimensional structure. The first refractive index variation pattern only supports propagation of light having a TM mode between the first direction and a third direction (z) and the second refractive index variation pattern only supports propagation of light having a TE mode between the second direction and the third direction.

  • Publication number: 20170151484
    Abstract: Virtual and augmented reality sports training environments are disclosed. A user interacts with virtual players in a simulated environment of a virtual reality sporting event. In some embodiments, the user's actions and decisions are monitored by the simulated environment. The environment evaluates the user's performance, and provides quantitative scoring based on the user's decisions and timing. Coaches and other users may design customized scenarios or plays to train and test users, and the resultant scores may be reviewed by the coach. In one application, real life pitchers and their pitching data are tracked and replicated in a simulated pitching environment. A team of users may practice against a simulation of a pitcher they are about to compete against, swinging at pitches that they would see in a real game. Such environments may maximize effective practice time for users, and help develop better players with improved decision-making skills.
