Patent number: 10280516Abstract: The described embodiments relate to methods and apparatus for increasing rigidity of a metal housing while maintaining or reducing a wall thickness of the metal housing. More particularly a method for embedding a stiffener layer within an aluminum substrate is discussed. In one exemplary embodiment the stiffener layer can be a carbon fiber sheet applied to an inside surface of an unfinished housing and then subsequently covered by depositing a layer of aluminum over the carbon fiber in a solid-state deposition process. The deposited aluminum can adhere to the unfinished housing around or through the carbon fiber layer to bond with the unfinished housing. Deposition parameters can be controlled to prevent damage to the carbon fiber sheet.Type: GrantFiled: May 16, 2014Date of Patent: May 7, 2019Assignee: Apple Inc.Inventors: Collin D. Chan, Matthew W.

Patent number: 9985345Abstract: Unitary structures having conductive portions electrically separated by non-conductive portions are described. In some embodiments, the non-conductive portions are made of metal oxide. In some embodiments, the method involves an oxidizing process adapted to convert an entire thickness at a selected portion of a metal substrate to a metal oxide, thereby creating metal portions that are electrically isolated from one another. In some embodiments, the thickness of the metal substrate is reduced at certain regions prior to oxidizing in order to provide a sufficiently thin metal for complete oxidization through the entire thickness. In some embodiments, the oxidizing process involves a plasma electrolytic oxidation process. In some embodiments, the plasma is concentrated at certain regions of the substrate for preferential oxidation. Applications for the substrate include enclosures and electrical components for electronic devices that use radio frequency communication.Type: GrantFiled: December 16, 2015Date of Patent: May 29, 2018Assignee: Apple Inc.Inventors: Francesco Ferretti, Joseph B. Marcinkowski, Collin D. Chan, Tom H. Engbersen

Patent number: 9951425Abstract: The described embodiments relate generally to methods for enhancing cosmetic surfaces of friction stir processed parts. More specifically a method for applying cold spray over a weld line generated by friction stir processing is disclosed. Methods are also disclosed for blending the cold spray applied over the weld line with a cosmetic surface portion of the friction stir processed parts. In some embodiments cold spray can be used to create a cosmetic joint between various parts. Structural joints between first and second substrates may also be formed via solid state deposition. Such joints may be strengthened through use of a hidden weld, mechanical interlocking between the substrates, and/or coupling via fasteners.Type: GrantFiled: July 24, 2014Date of Patent: April 24, 2018Assignee: Apple Inc.Inventors: Simon R.

Patent number: 9855637Abstract: A method and system for observing and monitoring thermal characteristics of a machining operation, such as a surface finishing operation, performed on a workpiece is disclosed. The surface finishing operation can be performed on the workpiece in order to remove a surface defect, e.g. a parting line, on a surface of the workpiece and/or to provide a mirror-like finish to the workpiece. In one embodiment, an emissive layer is applied to the workpiece to increase a thermal emissivity of the workpiece. In some embodiments, a finishing surface, such as a polishing or buffing wheel, and/or a lubricant used in a finishing operation is monitored. A thermal profile of the surface of the workpiece, finishing surface and/or lubricant can be obtained. The finishing operation can be modified in response to the monitored thermal characteristics to prevent the occurrence of defects and improve the efficacy of the finishing operation.Type: GrantFiled: March 4, 2015Date of Patent: January 2, 2018Assignee: Apple Inc.Inventors: Lucas Allen Whipple, Simon Regis Louis Lancaster-Larocque, Collin D.
