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.

Electronic devices are disclosed that include metal members bonded to members including a polymer material via a porous metallic layer. The polymer material may at least partially fill and mechanically interlock with pores of the porous metallic layer to form an interlock region.

Electronic device enclosure having a molded structure and a porous metallic structure

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.

Core shell with various filler materials for enhanced thermal conductivity

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.

An element for an electronic device can include a metal exterior portion including a first material, an interior portion including a second, independently selected material, and an engagement feature formed on a surface defined by the exterior and interior portions. The engagement feature can mechanically engage a material molded to the surface. A method for forming an element for an electronic device can include joining a boss to a member, forming a feature in the member while orienting the member via the boss, and at least partially removing the boss to form the element. An electronic device can include a frame defining an interior volume of the device, a display component, a transparent cover positioned adjacent to the display component, and an encapsulating material at least partially surrounding the display component and joining the display component to the frame.

A cooling system for a fuel injector system of a gas turbine engine has a heat exchanger for cooling a portion of diffuser case air and then routing the cooled diffuser case air through a sleeve that surrounds a fuel injector conduit located in at least the diffuser case plenum for minimizing fuel heat-up rates in the conduit. By minimizing fuel temperatures within the injector conduit, coking accumulation is thereby eliminated or reduced.

Embodiments describe an apparatus for magnetic charging and optical data transferring. The apparatus includes an inductive transmitting coil disposed within a housing, an optically transparent window disposed at a surface of the housing and above the inductive transmitting coil, and a first optical data transfer module disposed within the housing below the optically transparent window. The first optical data transfer module may be to perform at least one of emitting optical signals through the optically transparent window or detecting optical signals passing through the optically transparent window.

A liner for a combustor of a turbine engine includes a cooling feature which projects from a backside and one or more effusion holes that communicate(s) through the liner. The effusion hole(s) surround an opening through said liner. The cooling feature may include a trip strip or a pyramid pin fin (e.g., a three-side pyramid pin fin, a conical pyramid pin fin). The effusion hole(s) may penetrate said cooling feature. The effusion hole(s) may define an angle less than or equal to ninety (90) degrees with respect to a face of said liner. The effusion hole(s) may be proximate an opening through said liner.
