摘要:
Embodiments herein relate to a heat sink having nano- and/or micro-replication directly embossed in a bulk solidifying amorphous alloy comprising a metal alloy, wherein the heat sink is configured to transfer heat out of the heat sink by natural convection by air or forced convection by air, or by fluid phase change of a fluid and/or liquid cooling by a liquid. Other embodiments relate apparatus having the heat sink. Yet other embodiments relate to methods of manufacturing the heat sink and apparatus having the heat sink.
摘要:
Headset connector systems and headset engaging connector systems are provided. Headset connector systems can include two or more headset connector contact regions. Headset engaging connector systems can include two or more headset engaging contact regions to provide at least one of power and data. The headset connector system or the headset engaging connector system can include switching circuitry electrically coupled to the respective contact regions. The switching circuitry can be operative to determine an interface orientation between the headset connector contact regions and the headset engaging contact regions. The switching circuitry can also be operative to selectively route received signals based on the determined interface orientation. At least a portion of the headset connector system or the headset engaging connector system can be magnetically attractive.
摘要:
Disclosed herein are methods of combining at least one bulk-solidifying amorphous alloy and at least one additional metal or alloy of a metal to provide a composite preform. The composite preform then is heated to produce an alloy of the bulk-solidifying amorphous alloy and the at least one additional metal or alloy of the metal.
摘要:
Various embodiments provide systems and methods for casting amorphous alloys. Exemplary casting system may include an insertable and rotatable vessel configured in a non-movable induction heating structure for melting amorphous alloys to form molten materials in the vessel. While the molten materials remain heated, the vessel may be rotated to pour the molten materials into a casting device for casting them into articles.
摘要:
Exemplary embodiments described herein relate to methods and apparatus for forming a coating layer at least partially on surface of a BMG article formed of bulk solidifying amorphous alloys. In embodiments, the coating layer may be formed in situ during formation of a BMG article and/or post formation of a BMG article. The coating layer may provide the BMG article with surface hardness, wear resistance, surface activity, corrosion resistance, etc.
摘要:
Techniques for attachment of sapphire substrates with other materials and the resulting structures are provided. One embodiment may take the form of an attachment method including creating an aperture within a sapphire substrate and filling the aperture with an attachment material. The method also includes mechanically coupling a member to the sapphire substrate using the attachment material.
摘要:
Described herein is a method of combining discrete pieces of BMG in to a BMG feedstock that has at least one dimension greater than a critical dimension of the BMG, by methods such as thermoplastic forming, pressing, extruding, folding or forging. Other embodiments relate to a bulk metallic glass (BMG) component or feedstock having discrete pieces of a BMG, wherein the BMG component or feedstock has at least one dimension greater than a critical dimension of the BMG.
摘要:
Described herein is a feedstock comprising BMG. The feedstock has a surface with an average roughness of at least 200 microns. Also described herein is a feedstock comprising BMG. The feedstock, when supported on a support during a melting process of the feedstock, has a contact area between the feedstock and the support up to 50% of a total area of the support. These feedstocks can be made by molding ingots of BMG into a mole with surface patterns, enclosing one or more cores into a sheath with a roughened surface, chemical etching, laser ablating, machining, grinding, sandblasting, or shot peening. The feedstocks can be used as starting materials in an injection molding process.
摘要:
Anodized electroplated aluminum structures and methods for making the same are disclosed. Cosmetic structures according to embodiments of the invention are provided by electroplating a non-cosmetic structure with aluminum and then anodizing the electroplated aluminum. This produces cosmetic structures that may possess desired structural and cosmetic properties and that may be suitable for use as housing or support members of electronic devices.
摘要:
Method and apparatus for implementing multiple push buttons in a user device are disclosed. The method includes detecting a location of a user input using one or more touch sensors, detecting a force of the user input using a switch, and generating a signal for representing one of the push buttons being pressed according to with the location and force of the user input.
