A floating water evaporation system for use in disposing of excess water from oil and gas drilling operations is provided. One or more nozzle arrays float on the surface of a wastewater pond a distance away from the pond shoreline. Each nozzle array includes a series of upright risers that extend above a water reservoir tank. Spray nozzles are mounted on each riser. The water reservoir tank is mounted between floating pontoons that elevate the nozzles a distance above the surface of the pond. Water from the pond is pumped through the nozzles to create a patterned spray of small evaporable droplets.

Described herein are devices, systems and methods for accessing devices, such as modules or printed circuit boards (PCBs), for electrical communications. Various connectors described herein utilize a side-edge surface of a device, such as a PCB, for connectivity in order to maximize the surface area on the PCB upon which electronic components can be mounted. Such connectors can be used to temporarily connect to devices (e.g., PCBs) for the purposes of debugging, testing and / or configuring circuitry, firmware and / or software. Each such connector utilizes the side-edge surface of a device along its thickness to provide connectivity, which is useful in many situations, including when the device (e.g., a PCB) is to be soldered as a part onto a larger board at a later point in time, or where multiple PCBs are stacked.

A sensor comprises silver nanoparticles in which substantially all of the surfaces of the silver nanoparticles are available for interaction with an analyte or for functionalization with a receptor which is capable of interacting with an analyte. Silver nanoparticles are preparated by forming the nanoparticles in the presence of a polymeric stabilizer such as PVA.

An apparatus for pre-heating ventilation air for a building. The apparatus includes a first sunlight-absorbent collector panel on the building. The panel is exposed to ambient air and defines a first air collection space between itself and the building. The first sunlight-absorbent collector panel has a plurality of air inlet openings to allow the ambient air to pass through the openings to the first air collection space. A second sunlight-absorbent collector panel on the building is adjacent the first sunlight-absorbent collector panel and defines a second air collection space between itself and the building. The second sunlight-absorbent collector panel has a plurality of air inlet openings to allow air to pass through the openings to the second air collection space. A glazing covers the second sunlight-absorbent collector panel and defines an intermediary air flow chamber between itself and the second sunlight-absorbent collector panel. The intermediary air flow chamber is in communication with the first air collection space to receive air therefrom. The air inlet openings in the second sunlight-absorbent collector panel provide communication between the intermediary air flow chamber and the second air collection space. An air outlet extends from the second air collection space into the building for air flow therethrough. A fan communicates with the air outlet for moving air from the second air collection space into the building, through the air outlet.

An electronic device includes a chassis base and a chassis cover which define an electronic enclosure. The chassis base includes a slant angle venting plate extending at an angle from a chassis base sidewall of the chassis base. The slant angle venting plate has a slant angle vent plate pattern formed therein. Further, the chassis cover includes a chassis cover venting pattern covering the slant angle vent plate pattern. As the slant angle venting plate is slanted, the available surface area in which to form the slant angle vent plate pattern is maximized thus maximizing air flow through the electronic enclosure.

LED lighting device includes LED light housing including hollow outer shell with planar mounting surface defined inner top side of accommodation chamber to face toward bottom opening and reflector cup mounted accommodation chamber and defining conical reflective surface therein and carrying lens at top center thereof with light exit surface of lens facing toward bottom opening of hollow outer shell, LED light-emitting module including circuit board mounted between planar mounting surface and lens, array of LEDs arranged front side of circuit board and control circuit with driver IC and capacitor thereof respectively arranged opposing front and back sides of circuit board for converting inputted AC power into stabilized DC power for driving LEDS. This structural design effectively increases available surface area of circuit board for circuit layout and related circuit layout insulation distance, allows installation of relatively larger amount of LEDs to increase overall brightness and makes reflector cup replaceable.

Damping valve having a damping valve body with at least one passage channel between two cover sides. An outlet opening of the passage channel leads into a cover-side annular channel which is limited by an outer annular valve support surface and by an inner annular valve support surface, the at least one annular valve support surface for at least one valve disk has a substantially constant width along the circumference, and the annular channel has a varying width along the circumference, and at least one valve support surface has a varying radius of curvature along the circumference.

A wipe system is provided that is comprised of an inner portion sealed within an outer portion before use. The inner portion, which is used for cleaning, for example, may be wetted or saturated with a disinfecting fluid. Removal of an edge associated with the outer portion allows it to be opened to expose the inner portion. The wipe remains interconnected to the outer portion during use so that an opposite side of the outer portion is the only surface in contact with the user's hand.
