Abstract:
In some embodiments, processes for testing for structural flaws in sapphire parts such as display cover plates used in the manufacturing of electronic devices are disclosed. A process may include transmitting a destructive acoustic signal onto a sapphire part, and determining whether the sapphire part failed in response to the destructive signal. The destructive acoustic signal may include a Rayleigh acoustic wave, wherein the destructive acoustic signal breaks the sapphire part if the sapphire part has a surface flaw larger than a specified size. In this manner, only sapphire parts that can withstand the destructive acoustic signal are used in manufacturing of the electronic device.

Abstract:
A layered coating for a sapphire component is described herein. The sapphire component comprises one or more layers of alumina adhered to the surface of a sapphire member. At least the first layer of alumina adheres to the surface of the sapphire member filling all defects in the surface forming a pristine new layer that also provides isolation from damage.

Abstract:
Methods and devices are disclosed for controlling an electronic device using data transmitted over radio signals. In some embodiments, a radio source may embed instructions to control an electronic device into a radio signal. Alternatively, data relating to test parameters of other test equipment may be embedded into the radio signal. For example, the radio source may use the RDS communications protocol to transmit the instructions in an FM radio signal. In a testing environment, the electronic device may locally save the test parameters, and associate the test parameters with the results of a test.

In some embodiments, a radio source may embed instructions to control an electronic device into a radio signal. For example, the radio source may use the RDS communications protocol to transmit the instructions in an FM radio signal. The electronic device may receive the radio signal and may perform the instructions included in the radio signal. For example, the instructions can include commands to launch a web-browser application and direct a web-browser to retrieve metadata from a website.
Abstract:
A sapphire sheet is laminated to a glass sheet with a gradient layer that transitions from a composition of predominantly Al2O3 at the sapphire sheet to a composition of predominantly SiO2 at the glass sheet. The gradient layer chemically bonds to both the sapphire sheet and the glass sheet and has no distinct interfaces.
