Abstract:
An in-ear hearing device having an ear interfacing portion integrally formed with an elongated stem portion, wherein the ear interfacing portion extends away from the elongated stem portion; a first acoustic port formed in the ear interfacing portion; a speaker disposed in the ear interfacing portion and aligned to emit sound from the acoustic port; a plurality of electrical contacts disposed at an end of the stem portion, the plurality of electrical contacts including first and second contacts; a second acoustic port formed at the end of the elongated stem portion between the first and second contacts; a microphone disposed in the stem portion; and a channel that fluidically couples the microphone to the second acoustic port.
Abstract:
A removable component for use with an earphone is disclosed. As an example, the removable component can be an ear tip. According to one aspect, an improved ear tip can be provided for use with a headphone. The ear tip is suitable for in-ear operation and can have a cosmetic deformable outer member. The deformable outer member can enable the ear tip to readily conform to a user's ear. The ear tip can also include an inner member to structurally support the outer member and to facilitate attachment to a headphone. Methods for forming such ear tips are also disclosed.
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:
An electronic device may be provided with a display mounted in a housing. The display may have an array of display pixels that provide light to a user. The array of display pixels may form active display structures with a rectangular shape. The rectangular active display structures may be surrounded by an inactive border region. Reflector structures may be used to reflect light that is emitted from peripheral portions of the active display structures to a portion of the display overlapping the inactive border region, thereby providing the display with an effective active area that is larger than the area of the active display structures. The reflector structures may include rotatable reflectors. Control circuitry may use a rotatable positioner to rotate rotatable reflector structures in synchronization with controlling which pixel data is displayed by the display pixels in the peripheral portions of the active display structures.
Abstract:
Various embodiments provide apparatus and methods for injection molding. In one embodiment, a constraining plunger may be configured in-line with an injection plunger to transfer a molten material from a melt zone and into a mold. The constraining and injection plungers are configured to constrain the molten material there-between while moving. The constrained molten material can be controlled to have an optimum surface area to volume ratio to provide minimized heat loss during the injection molding process. The system can be configured in a longitudinal direction (e.g., horizontally) for movement between the melt zone and mold along a longitudinal axis. A molded bulk amorphous object can be ejected from the mold.
Abstract:
Disclosed are systems and methods for mechanically reducing an amount of the skull material in a finished, molded part formed from amorphous alloy using an injection molding system. Skull material of molten amorphous alloy can be captured in a trap before molding such material. A cavity can be provided in the injection molding system to trap the skull material. For example, the cavity can be provided in the mold, the tip of the plunger rod, or in the transfer sleeve. Alternatively, mixing of molten amorphous alloy can be induced so that skull material is reduced before molding. A plunger and/or its tip can be used to induce mixing (e.g., systematic movement of plunger rod, or a shape of its tip). By minimizing the amount of skull material in the finished, molded part, the quality of the part is increased.
Abstract:
A protective film configured to protect a substrate such as a glass panel for a display is provided. The protective film may include a discontinuous outer layer including a multitude of panels and gaps positioned therebetween. Further, the protective film may include a flexible layer positioned between the discontinuous outer layer and the substrate. When panels of the discontinuous outer layer are impacted by a foreign object, the force may be transferred to the flexible layer, rather than propagating through the outer layer. In this regard, the gaps between the panels of the discontinuous outer layer may prevent the formation of cracks that may otherwise occur. Related assemblies and methods are also provided.
Abstract:
Systems and methods for positioning a component on a surface or substrate including the steps of applying a coating to a selected deposit area of the surface, each deposit area defining at least a portion of a perimeter of an alignment area, depositing an fluid on the coating, and depositing, dropping, or otherwise positioning the component above the alignment area are disclosed.
Abstract:
Described herein are methods of constructing a part using metallic glass alloys, layer by layer, as well as metallic glass-forming materials designed for use therewith. Metallic glass meshes, metallic glass actuators, three dimensional metallic glass thermal history sensors, and methods of their manufacture are also disclosed.
