Abstract: A roof integrated solar power system includes a plurality of solar modules. Each solar module carries a photovoltaic or solar panel with solar cells. Edge regions of the solar module are disposed to the sides of the solar panel and are devoid of solar cells. An electrical component such as a junction box or micro-inverter, or DC optimizer is mounted on top of the solar module within at least one of the edge regions. Cabling for interconnecting the electrical component to electrical components of others of the plurality of solar modules also is located within the side regions. In one embodiment, the electrical component and cabling is disposed within a recess within a side region and covered by a flat access panel. In another embodiment, the electrical component and cabling is located atop the side region and is covered by an access panel in the form of a protective cover strip.

Abstract: Embodiments provide image display systems and methods for a camera calibration using a two-sided diffractive optical element (DOE). More specifically, embodiments are directed to determining intrinsic parameters of a camera using a single image obtained using a two-sided DOE. The two-sided DOE has a first pattern on a first surface and a second pattern on a second surface. Each of the first and second patterns may be formed by repeating sub-patterns that are lined when tiled on each surface. The patterns on the two-sided DOE are formed such that the brightness of the central intensity peak on the image of the image pattern formed by the DOE is reduced to a predetermined amount.

Abstract: Techniques are disclosed for allowing remote participation in collaborative video review based on joint state data, for a video collaboration session, maintained by a video collaboration service. A user at a participant client device may provide one or more annotations, such as a drawing annotation, for the video data via a client application. The client application transmits computer-readable instructions for re-creating the drawing annotation to the service, which distributes the drawing instructions to the other participant client devices. Using the drawing instructions, the client applications at the client devices are configured to re-create the drawing annotation on the associated video frame displayed at the client devices. The joint state data communicated to client devices for a given session may include co-presence data that efficiently increases communication among the participants in a session.

Abstract: In general, the subject matter described herein relates to wettable materials that can be used to expose a liquid phase to a gas phase. An example method includes: providing a material including a polymeric substrate and at least one of: a silicate coating disposed over the polymeric substrate; or a polar mineral additive dispersed within the polymeric substrate at a loading from about 1% to about 25%, by weight; and using the material in a chemical process in which the material is at least partially covered by a liquid phase and the liquid phase is exposed to a gas phase.

Abstract: A visual perception device is described. The visual perception device has corrective optics for viewing virtual and real-world content. An insert for the corrective optics is attached using a magnetic set, pins and/or a nose piece. Interchangeable nose pieces allow for height adjustments to accommodate different users. The visual perception device has pliable components to absorb forces exerted on a nose piece and a protective barrier for limiting electric shock or ingress of dirt.

Abstract: In one aspect, a PCB is provided. The PCB includes at least one insulating layer, a blind slot, and at least one via. The at least on insulating layer includes a first surface and a second surface opposite the first surface. The blind slot is plated and formed in the at least one insulating layer, where the blind slot partially extends from the first surface to the second surface, and where the blind slot includes a conductive plating bonded along a major surface of the blind slot. The at least one via is electrically conductive and filled, where the at least one via is coupled with and extends between the conductive plating of the blind slot and the second surface of the at least one insulating layer.

Abstract: There is provided a turf cup assembly that attaches to a buried pop-up type sprinkler to blend a top of sprinkler both cosmetically and functionally with turf surrounding the sprinkler. The turf cup assembly includes a turf cup and a sleeve. The turf cup mounts to a riser of the pop-up type sprinkler. The turf cup contains soil and root structure of turf. The sleeve surrounds the turf cup and attaches to a top of a housing of a pop-up sprinkler. The sleeve can be at or slightly below grade, and the cup extends out of the sleeve during an irrigation cycle and retracts into the sleeve at the end of the irrigation cycle.

Abstract: A tool configured for use to assemble and install trim into a steam conditioning valve. These configurations can include a device that mounts in place of a bonnet and an actuator that technicians remove from the valve. The device can cantilever the trim assembly, essentially providing a platform on which technicians can slide the trim assembly into the valve body (or out of the valve body) to complete install or repair of the device. As an added benefit, technicians can also use the device to assemble the trim in proximity to the subject valve.

Abstract: A method of manufacturing a connector device suitable for making an inter or intra static electrical energy converter connection. The device includes at least two flat conductors and at least one insulating material. The said method includes: preparing each flat conductor individually; applying at least one coat of enamel varnish to each conductor, which is thinner than a desired final thickness; carrying out cross-linking of the enamel coating; and repeating the depositing of a layer of enameling resin and the cross-linking until the chosen thickness is reached. The varnish coated conductors of the connector device are assembled by using a template and connecting elements.

Abstract: A combined paddle and pump can be used to propel a small boat. The handle telescopes with a locking nut that may be loosened to allow extension and retraction of the handle. The handle is hollow throughout and a pair of check valves are provided. One check valve opens when the handle is extended and the other opens when the handle is retracted. When one check valve is open, the other is closed. When the distal end of the paddle is placed within a volume of water or exposed to atmospheric, extension and retraction of the handle results in a fluid first being sucked into the hollow interior of the handle and then propelled out of the handle. A seal assembly prevents debris from binding tubes of the handle.
