Abstract:
A multichannel manifold cold plate with microchannels for cooling electronics. A main inlet is on a side of the microchannels opposite the cold plate and includes inlet channels with nozzles adjacent the microchannels. A main outlet is on a side of the microchannels opposite the cold plate and includes outlet channels with nozzles adjacent the microchannels. The inlet channels are interleaved with the outlet channels. In operation, the main inlet delivers a cooling fluid to the cold plate microchannels via the inlet channels and nozzles, and the main outlet receives the cooling fluid from the microchannels via the outlet channels and nozzles. This configuration provides a cooling fluid distribution pattern for efficient cooling of the electronics.
Abstract:
A hardcoat composition includes one or more multifunctional (meth)acrylate monomers, and a nanoparticle mixture dispersed within the one or more multifunctional (meth)acrylate monomers. The nanoparticle mixture includes a first population of reactive nanoparticles. The first population of reactive nanoparticles have an average particle diameter in a range from 5 nm to 60 nm, and a second population of non-reactive nanoparticles. The second population of non-reactive nanoparticles have an average particle diameter in a range from 5 nm to 60 nm.
Abstract:
A display film includes a transparent polymeric substrate layer and a transparent energy dissipation layer disposed on the transparent polymeric substrate layer. The transparent energy dissipation layer includes cross-linked polyurethane and a polyacrylate polymer. The transparent energy dissipation layer has a glass transition temperature of 27 degrees Celsius or less and a Tan Delta peak value of 0.5 or greater.

Abstract:
Variable index light extraction layers that contain a first region with a first material and a second region including a second material are described, where the first region has a lower effective index of refraction than the second region. Optical films and stacks may use the variable index light extraction layers in front lit or back lit display devices and luminaires.
Abstract:
This application describes a back- lit transmissive display including a transmissive display ( 620 ) and a variable index light extraction layer ( 640 ) optically coupled to a lightguide ( 630 ). The variable index light extraction layer has first regions ( 140 ) of nanovoided polymeric material and second regions ( 130 ) of the nanovoided polymeric material and an additional material. The first and second regions are disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light extraction layer selectively extracts the light in a predetermined way based on the geometric arrangement of the first and second regions. The transmissive display may be a transmissive display panel or a polymeric film such as a graphic.

Abstract:
Processing tapes for use in preparing optical articles include a thermally stable tape backing and a low tack adhesive layer at least partially coated on tape backing. The low tack adhesive layer includes a crosslinked, polyester-containing (meth)acrylate-based polymer that is essentially free of volatile components, is unchanged after heat aging of 150C for 1 hour under a pressure of 4.31 kiloPascals, and is able to removably adhere to the anti-reflective, nanostructured surface coating of an optical construction.
