Filed:

Aug 16, 2021

Appl. No.:

17/403677

Inventors:

- Cupertino CA, US
Alexander W. WILLIAMS - Santa Clara CA, US

International Classification:

A61B 5/00
A61B 5/0531
A61B 5/0537

Abstract:

Hydration measurement capabilities can be provided by a wearable electronic device, such as a watch, to allow a user to easily track hydration. A watch can be positioned to receive and measure one or more electrical properties of perspiration produced by the user wearing the watch. The watch provides electrodes for measuring the electrical properties of the perspiration. The electrical properties, such as electrical conductance, can represent a concentration of electrolytes in the perspiration, which in turn represents a hydration level of the user. The hydration tracking can be performed non-invasively, repeatedly, accurately, automatically, and with minimal user intervention. The measurements can be used to provide useful feedback and health tracking information to a user, thereby allowing the user to better manage hydration and overall health.

Abstract:

A method of forming a surface coating on a component of an electronic device can include depositing an aluminum layer including at least about 0.05 weight percent (wt %) of a grain refiner on a surface of the component by a physical vapor deposition process, and anodizing the aluminum layer to form an anodized aluminum oxide layer having a L* value greater than about 85 in the CIELAB color space.

Abstract:

A composite housing of an electronic device can include a metal shell including a first material having a first set of material properties and a surface at least partially defining an exterior surface of the electronic device. The composite housing can also include an interior portion including a second material having a second set of material properties independent of the first set of material properties and at least partially defining a feature. The interior portion can be bonded to the shell and disposed interior to the surface of the shell.

Appl. No.:

15/069125

Inventors:

- Cupertino CA, US
Alexander W. Williams - Santa Clara CA, US

Assignee:

Apple Inc. - Cupertino CA

International Classification:

H01R 13/22
H01R 13/03

Abstract:

Electrical contacts are described. An electrical contact can be formed on an exterior surface of a housing of an electronic device and can be cosmetically similar to the exterior surface. For example, the electrical contact can include a conductive plug inserted through an opening in a wall of the housing. A metallic coating can be applied to an outward-facing end of the conductive plug and fill up an outer portion of the opening until the metallic coating is about flush with the exterior surface of the housing. Properties of the metallic coating can be selected to closely match a color and a texture of the housing.

International Classification:

G06F 1/16

Abstract:

A cover glass including a center region and an outer region abutting the center region at an interface. The interface inhibits crack propagation from the outer region to the center region and vice versa. In another embodiment the cover glass may include mitigation voids introduced into the cover glass to inhibit crack propagation. The interface may be formed from the mitigation voids.
