WO/2016/148689 UNIDIRECTIONAL GRATING-BASED BACKLIGHTING EMPLOYING AN ANGULARLY SELECTIVE REFLECTIVE LAYER||WO||22.09.2016|
||PCT/US2015/020841||LEIA INC.||FATTAL, David A.|
Unidirectional grating-based backlighting includes a light guide and a diffraction grating at a surface of the light guide. The light guide is to guide a light beam and the diffraction grating is configured to couple out a portion of the guided light beam using diffractive coupling and to direct the coupled-out portion away from the light guide as a primary light beam at a principal angular direction. The diffraction grating is to further produce a secondary light beam directed into the light guide at an opposite one of the principal angular direction. The unidirectional grating-based backlighting further includes an angularly selective reflective layer within the light guide adjacent to the light guide surface that is configured to reflectively redirect the diffractively produced, secondary light beam out of the light guide in the direction of the primary light beam.

The first and second elements (52, 54) include respective distal edges (52d, 54d) that laterally overlap each other at the lateral location.
WO/2016/148671 METHODS AND SYSTEMS FOR MAINTAINING OPTICAL TRANSPARENCY DURING PARTICLE IMAGE ACQUISITION||WO||22.09.2016|
||PCT/US2015/020348||HALLIBURTON ENERGY SERVICES, INC.||ROWE, Mathew Dennis|
Fouling of or damage to an electromagnetic radiation-transparent window can preclude one from obtaining satisfactory images with an image acquisition unit, such as a camera. Certain types of environments may be particularly prone toward promoting fouling or damage, and manual cleaning or repair of an electromagnetic radiation-transparent window may be difficult in some circumstances. These issues may be particularly prevalent when imaging drill cuttings and other solids obtained from a wellbore due to the complex sampling environment in which these solids are often disposed. Wellhead imaging systems can comprise: a flow pathway extending from a wellbore; an electromagnetic radiation-transparent window external to the wellbore establishing optical communication with the flow pathway; an image acquisition unit in optical communication with the flow pathway via the electromagnetic radiation-transparent window; and a movable barrier that is also electromagnetic radiation-transparent and is disposed between the electromagnetic radiation-transparent window and the flow pathway.

A liquid coating composition is provided, comprising (i) a film-forming compound; (ii) an aqueous medium; and (iii) a urea compound. Methods of using such a coating composition, and multilayer coating systems including such a coating composition are also disclosed.
WO/2016/148720 WELLBORE ISOLATION DEVICES AND METHODS OF USE||WO||22.09.2016|
||PCT/US2015/021479||HALLIBURTON ENERGY SERVICES, INC.||STAIR, Todd Anthony|
A wellbore isolation device includes an elongate body and a packer assembly disposed about the elongate body and including upper and lower sealing elements positioned axially between an upper shoulder and a lower shoulder, a spacer interposing the upper and lower sealing elements and having an annular body that provides an upper end, a lower end, and a recessed portion extending between the upper and lower ends. An upper cover sleeve is coupled to the upper shoulder, and a lower cover sleeve is coupled to the lower shoulder. An upper support shoe has a lever arm extending over the upper sealing element and a jogged leg received within a gap defined between the upper cover sleeve and shoulder. A lower support shoe has a lever arm extending over the lower sealing element and a jogged leg received within a gap defined between the lower cover sleeve and shoulder.
WO/2016/148678 OVERCOMING THE RETARDATION OF CEMENT HYDRATION FROM DISPERSING AGENTS USED IN SUSPENSION OF ADDITIVES||WO||22.09.2016|
||PCT/US2015/020485||HALLIBURTON ENERGY SERVICES, INC.||PEARL, William, Cecil, Jr.|
A method of cementing a subterranean formation includes forming a cement composition comprising cementitious material, an aqueous base fluid, a nano-reinforcement particle suspension comprising a surfactant; and pozzolanic material; introducing the cement composition into a subterranean formation; and allowing the cement composition to set in the subterranean formation. A method of making a cement composition includes combining cementitious material, an aqueous base fluid, a nano-reinforcement particle suspension comprising a surfactant, and a pozzolanic material, where the rate of hydration of the surfaces of the cementitious material is less retarded by the surfactant than an equivalent cement composition without pozzolanic material.
WO/2016/148677 CONFIGURING MANAGED DEVICES||WO||22.09.2016|
||PCT/US2015/020480||HEWLETT PACKARD ENTERPRISE DEVELOPMENT LP||DANDABANY, Sankarlingam|
Example implementations relate to configuring managed devices. For example, a device includes a controller to receive a network configuration from a management device, and temporarily apply the network configuration and attempt a network connection with the management device using the network configuration. The controller is to configure the device with the network configuration if the network connection is established using the network configuration, and revert to a previous network configuration if the network connection is not established using the network configuration.

A side-fire laser fiber (102) includes an optical fiber (112) having a distal end (116) and a fiber cap (114). The fiber cap is coupled to the distal end of the optical fiber and includes a molded reflective surface (130) and a sealed cavity (132A or 132B). The molded reflective surface defines a wall of the cavity. Laser energy discharged from the distal end along a central axis (124) of the optical fiber is reflected off the molded reflective surface in a direction that is transverse to the central axis.
