Abstract

Articles and methods for temporary bonding of substrates are described. The articles include a photo-release layer to enable reversal of the temporary bonding upon exposure of the photo-release layer to light to separate the substrates. The method includes plasma treatment of the photo-release layer to increase the bonding energy. Higher bonding energy allows for processing of the article with greater mechanical force before separation. Plasma treatment also allows for temporary bonding with a thinner photo-release layer and a photo-release layer with low total thickness variation (TTV). Once separated from the article, a processed substrate can be bonded to other substrates.

A plurality of core segments are defined between pairs of adjacent slots. A plurality of bend regions are arranged around respective terminal ends of the slots. Each pair of adjacent core segments is connected by a corresponding one of the bend regions. An auxiliary conductive feature is located within each of the bend regions. The plurality of slots electrically disconnect each pair of adjacent core segments from each other to create a serpentine current-carrying path that extends across the heater body through the electrically conductive material of the core segments and the bend regions. Each of the auxiliary conductive features locally reduces an electrical resistance of the heater body in the bend regions in comparison to the electrically conductive material alone.

Abstract

Described herein are articles with scattering regions comprising a plurality of microstructures that are elongated in a first direction so as to preferentially scatter light in one or more directions. Each of the plurality of microstructures comprises a feature size measured in a second direction that is perpendicular to the first direction. The feature size varies as function of position within the microstructure to achieve favorable transmission haze performance while also suppressing scattering of light at relatively high scattering angles relative to specular to improve display washout from external light sources. A two-dimensional power spectral density of the first major surface comprises a peak region that is entirely disposed on one side of an axis associated with scattering directions that are parallel with the first direction.

Abstract

Articles and methods for temporary bonding of substrates are described. The articles include a photo-release layer to enable reversal of the temporary bonding upon exposure of the photo-release layer to light to separate the substrates. The method includes plasma treatment of the photo-release layer to increase the bonding energy. Higher bonding energy allows for processing of the article with greater mechanical force before separation. Plasma treatment also allows for temporary bonding with a thinner photo-release layer and a photo-release layer with low total thickness variation (TTV). Once separated from the article, a processed substrate can be bonded to other substrates.

Abstract

A method of fabricating a glass panel includes forming a non-chamfered glass panel by cutting a glass sheet. The non-chamfered glass panel is formed by cutting the glass sheet along a first sideline segment, cutting the glass sheet along a corner line segment set connected to the first sideline segment, and cutting the glass sheet along a second sideline segment connected to the corner line segment set. An extension of the first sideline segment and an extension of the second sideline segment intersect each other at a first interior angle narrower than 230°. The first sideline segment and the corner line segment set are connected at an interior angle wider than the first interior angle and 180° but narrower than 230°. The corner line segment set and the second sideline segment are connected at an interior angle wider than the first interior angle and 180° but narrower than 230°.

Abstract

Machine learning assisted beamforming heatmap determination of a wireless communications system (WCS) is provided. The WCS includes multiple wireless nodes each configured to form one or more radio frequency (RF) beams to provide RF coverage in a large service venue. To ensure that the wireless nodes can collectively provide a desirable coverage, it is often necessary to compute a beamforming heatmap for each RF channel in each of the wireless nodes. Herein, a computing device is configured to train a machine learning network based on a selected subset of the wireless nodes and then use the trained machine learning network to generate the beamforming heatmaps for all the wireless nodes in the WCS. With assistance from the machine learning network, it is possible to generate and/or regenerate the beamforming heatmap of the WCS with less processing time and/or computational resources to therefore enable fast deployment of the WCS.

Abstract

A device and a process for forming a monolithic substantially closed-porosity ceramic fluidic device having a tortuous fluid passage extending through the device, the tortuous fluid passage having a smooth interior surface, a material of the ceramic body having a continuous and uniform distribution of grains at least between opposed major surfaces of the ceramic body. The process includes positioning a positive fluid passage mold within a volume of binder-coated ceramic powder, pressing the volume of ceramic powder with the mold inside to form a pressed body, heating the pressed body to remove the mold, and sintering the pressed body. A relationship between a first stability characteristic of the volume of ceramic powder and a second stability characteristic of the mold prevents discontinuities in the pressed body after pressing and/or during heating.
