Abstract: According to one aspect, a computer-implemented method for automatically generating a video advertisement is provided. The method includes obtaining one or more attributes relating to a video advertisement. The method includes obtaining a template, wherein the template comprises one or more blocks, wherein each block of the one or more blocks comprises one or more placeholders corresponding to one or more types of media assets. The method includes identifying, in a first block of the one or more blocks in the template, a first placeholder corresponding to a first type of media asset. The method includes selecting a first media asset from a first media library based on first metadata associated with the first media asset, the one or more attributes, and the first type of media asset. The method includes generating, using a rendering engine, a video advertisement, wherein the generated video advertisement comprises the first asset. The method includes outputting the generated video advertisement.

Abstract: A manifold device for a multi-jet pool fixture includes a central chamber having a jet interface surface. An inlet in fluid communication with the central chamber allows fluid to flow into the central chamber and out a plurality of openings disposed in the jet interface surface. An outlet in fluid communication with the central chamber allows water to flow out of the central chamber.

Abstract: An improved component for use in a deposition chamber is constructed from ceramic zirconia and a stabilizing compound. The zirconia is preferably in a partially stabilized form and is coated with a metallic layer such as thermally sprayed aluminum. The surface of the zirconia is roughened to improve adhesion between the zirconia and the aluminum. Alternatively, an intermediate layer may be deposed between the zirconia and the metallic layer to improve the bonding between the layers. The coated zirconia component resists flaking when covered with materials that are being deposited in the deposition chamber and, thus, reduces the likelihood that devices being constructed in the deposition chamber will be contaminated by loose particles.

Abstract: A fire hydrant wrench is provided with a chatter-thread arrangement that permits a threaded handle to be pushed, rather than manually threaded, into engagement with a fire hydrant fixture. A quick release trigger similarly permits the handle to be quickly withdrawn without unthreading. Faster operation of hydrants, with consequent savings of lives, results. Other improvements are also disclosed, including reversible, replaceable gripping teeth that tend to prevent even a loosely coupled wrench from falling off a fire hydrant.

Abstract: A spectrometer apparatus is provided including means for focusing a light beam with a concave holographic grating, means for passing light reflected from the grating through a step order filter to an array detector and means for processing signals from the array detector. The spectrometer permits monitoring a plurality of grating orders simultanously without mechanical scanning.
