    Abstract: A metal matrix composite using as one of the components a precious metal is described. In one embodiment, the precious metal takes the form of gold and the metal matrix composite has a gold mass fraction in accordance with 18 k. The metal matrix composite can be formed by blending a precious metal (e.g., gold) powder and a ceramic powder, forming a mixture that is then compressed within a die having a near net shape of the metal matrix composite. The compressed mixture in the die is then heated to sinter the precious metal and ceramic powder. Other techniques for forming the precious metal matrix composite using HIP, and a diamond powder are also disclosed.

    Abstract: The described embodiments relate generally to cosmetic surfaces and associated treatments to form cosmetic surfaces. Cosmetic surface treatments as described herein both increase durability and decrease the appearance of physical damage through implementation of an intermediate barrier layer having a first physical attribute (e.g., color of barrier layer) of a predetermined relationship with a second physical attribute of a second layer (e.g., color of a cosmetic layer). The intermediate barrier layer separates the second layer (e.g., a cosmetic or external layer) from internal material supporting both. The first physical attribute may be chosen to be of a similar appearance to the second physical attribute (e.g., matching and/or somewhat closely matching in color) such that physical damage to the cosmetic layer is made less visible.

    Abstract: A shield assembly can enclose an electronic component in a chamber of a mobile communication device. The shield assembly can include a chassis having a slot and a conductive rail adjacent to the slot. A covering can be mounted over the electronic component and coupled to the chassis via a spring contact disposed in the slot. The covering can include a shield element configured to cover a chamber enclosing the electronic component. The covering can further include a first tab connected to the shield element, and a second tab connected to the shield element and spaced apart from the first tab by a gap. A spring contact can be disposed in the gap and electrically connected to the shield element via at least one of the first tab and the second tab.
