Abstract:
A component for an electronic device including an internal compressive stress region is disclosed herein. The internal compressive stress region may be created in a glass portion of the component or in a glass ceramic portion of the component. Electronic devices comprising the components and method for making the components are also disclosed.
Abstract:
A property-enhanced cover sheet, and methods for forming a property-enhanced cover sheet, for a portable electronic device are disclosed. A property-enhanced cover sheet is formed by thermoforming a glass sheet into a specified contour shape while modifying one or more properties of the glass. Other property-enhanced sheets can be formed by layering two or more glass sheets having different material properties, and then thermoforming the layered sheets into a required contour shape. Property enhancement for a cover sheet includes, hardness, scratch resistance, strength, elasticity, texture and the like.
Abstract:
Asymmetrically strengthened glass articles, methods for producing the same, and use of the articles in portable electronic device is disclosed. The asymmetrically strengthened glass articles include glass articles having a deeper compressive stress layer in a thicker portion of the glass article. Using a budgeted amount of compressive stress and tensile stress, asymmetric chemical strengthening is optimized for the utility of a glass article. In some aspects, the strengthened glass article can be designed for reduced damage, or damage propagation, when dropped.
Abstract:
A material testing apparatus and methods of testing material are disclosed. The material testing apparatus may include a support ring contacting a test material and a moveable contact component positioned adjacent to the support ring. The moveable contact component may include a substantially curved contact surface comprising a radius-varying curvature profile formed between a center and a perimeter of the substantially curve contact surface. The curvature profile may be based on a predetermined deflection-force profile specific to the test material. Additionally, the curvature profile may also be based on the material characteristics of the test material, the physical characteristics of the test material, the physical characteristics of the support ring and/or a testing process performed on the test material.

Abstract:
An electronic device includes a housing coupled to a display window, a battery and a plurality of inductive charging transmit coils coupled to the battery. The plurality of inductive charging coils are positioned within the enclosure to generate an inductive charging region that extends through the display window and across at least a portion of an exterior of the display window. Sensing circuitry is configured to sense a position of a stylus at the display window and a processor is configured to selectively engage and disengage one or more of the plurality of inductive charging transmit coils based on the sensed position of the stylus. The stylus receives power when it is positioned within the inductive charging window.
