For a substantially normally incident light and for a visible wavelength range of about 420 nm to about 680 nm and an infrared wavelength range of about 900 nm to about 1100 nm: for the incident light polarized along each of mutually orthogonal in-plane first and second directions. the plurality of polymeric layers has an optical transmittance of greater than about 60% for at least one visible wavelength in the visible wavelength range and an optical reflectance of greater than about 60% for at least one infrared wavelength in the infrared wavelength range. For the incident light polarized along at least one of the first and second directions, the optical retarder has an optical retardance of greater than about 1000 nm at the at least one visible wavelength.

In particular, a filter securement assembly for receiving and retaining a filter media in an exhaust hood includes a main panel defining a first end and an opposed second end, a first retainment surface adjacent the first end of the main panel, a first retainment lip adjacent the first retainment surface, a second retainment surface adjacent the second end of the main panel and a second retainment lip adjacent the second retainment surface.

Abstract: The present disclosure relates to articles and methods of sealing light redirecting film constructions comprising a microstructured optical film, such as a daylight redirecting film, bonded to another film. This type of assembly may serve various purposes. For example, the assembly may protect the structured film, provide additional functionality, such as diffusion or infrared reflection, and/or facilitate attachment of the microstructured optical film to a mounting surface, such as a glazing or window pane. The methods for sealing the edge of a light redirecting construction inhibit ingress of water and other contaminants during the film installation and afterwards during its regular use.

Abstract: The present invention is directed to a system and method for producing an organic compound using fermentation wherein multiple components of the system are recycled within the system. The system and method allow for extraction of a high concentration of the organic compound from the fermentation broth in a continuous system that allows recycling of the biomass, aqueous fermentation broth and extraction solvents. The system and method are particularly well adapted for producing and extracting ethanol.

Abstract: Microoptical layers, glazing units including the microoptical layers, and transfer tapes that may be used to provide the microoptical layers are provided. The transfer tape includes a removable template layer having a structured surface, a backfill layer having a first surface disposed on at least a portion of the structured surface of the template layer, and a microstructured surface opposite the structured surface. The microstructured surface together with a layer disposed on the microstructured surface is an anisotropic diffuser.

Abstract: Described herein is a membrane separation module and articles and methods thereof, wherein the membrane separation module has a series of repeating layers, each layer comprising (a) a selectively permeable membrane; and (b) at least one support layer, wherein the support layer comprises a plurality of flow channels and a plurality of rails extending from the support layer, wherein the sides of two adjacent rails form a flow channel, wherein the plurality of rails on the support layer comprise a thermoplastic polymer at the distal end of at least a portion of the plurality of rails, and wherein the distal end of the plurality of rails contacts the selectively permeable membrane to form a bonded stack.

Abstract: A dust collection device for a sanding tool includes a bag having a sidewall with an inner surface and a coupler attached to the bag. The sidewall comprises at least one filter layer and an outer support layer. A sleeve having an outer surface, a sleeve sidewall, a first end, a second end, and at least one gap at either the first end or the second end is positioned within the bag. The sleeve's first end is positioned adjacent the coupler to direct incoming air towards the sleeve and the sleeve is positioned within the bag such that a bypass volume is present between the outer surface and the inner surface.

Abstract: There is provided a structure and a method to detect a signal prompted by the use of a wireless communications device in a motor vehicle or, optionally, in the area of a vehicle operator station. A signal detection will set off audible and/or visual alarms. The alarms may continue until the signal is no longer detected.

Abstract: An operational data store consists of an insert table for storing new data and a history table, partitioned by range and further sub-partitioned, for storing historical data. Transfer logic periodically transfers new data from the insert table to the history table. The transfer logic includes a secondary table and fill logic for filling the secondary table with selected data from the insert table. Secondary transfer logic transfers the secondary table into the history table, such that the selected data is transferred into the history table. Indexing logic applies the history table indexing scheme to the secondary table. Table logic creates a new partition the history table, for swapping with the secondary table, by exchanging respective pointers. A query engine may apply a database query to both the history table and the insert table, so that all data is available. An aggregator accumulates new data into an aggregation buffer.
