Patent number: 11201426Abstract: Methods of coating contacts to have a specific color. The color can be selected to match a color of a portion of a device enclosure for an electronic device housing the contacts. Examples can instead provide methods of coating contacts to have a color to contrast with a color of a portion of the device enclosure. These methods can provide electrical contacts having a low contact resistance and good corrosion and scratch resistance.Type: GrantFiled: August 13, 2019Date of Patent: December 14, 2021Assignee: Apple Inc.Inventors: Raymund W.

Patent number: 10998657Abstract: Contacts that can be highly corrosion resistant, can be readily manufactured, and can conserve precious materials. One example can provide contacts having a layer of a precious-metal alloy to improve corrosion resistance. The precious-metal-alloy layer can be plated with a hard, durable, wear and corrosion resistant plating stack for further corrosion resistance and wear improvement. The resources consumed by a contact can be reduced by forming a bulk or substrate region of the contact using a more readily available material, such as copper or a material that is primarily copper based.Type: GrantFiled: September 9, 2019Date of Patent: May 4, 2021Assignee: Apple Inc.Inventors: Hani Esmaeili, Kenneth Michael Bagwell, Holly Ubellacker, Judy Hsien-Chih Liu, Eric S.

Publication number: 20190103693Abstract: Electrical contacts having good corrosion resistance. These contacts may include a set of three layers. The three layers may include a first or top layer and two layers below the top layer. The second or middle layer may be more electrochemically active than either the first layer or the third layer. The first layer may include cracks, pores, or other discontinuities. Corrosive substances may pass through these cracks, pores, and other discontinuities and corrode the second, more electrochemically active layer below the first layer. The cracks, pores, and other discontinuities may spread the corrosion homogenously and laterally across the surface of the contact, thereby protecting the remainder of the contact.Type: ApplicationFiled: March 30, 2018Publication date: April 4, 2019Applicant: Apple Inc.Inventors: Michael W.

Patent number: 9977148Abstract: A method for synchronizing a light grid comprising a transmitting unit having a plurality of transmitters and a receiving unit having a plurality of receivers. A transmitter control unit activates the transmitters one after another in a cycle, and a receiver control unit evaluates the receivers. Each transmitter is associated with a receiver, and an activated transmitter transmits a transmission beam to its associated receiver. At least two transmission beams in the cycle are synchronization transmission beams which are emitted at a time offset from one another. The receiver control unit measures the time offset, and the synchronization transmission beams are uniquely associated with the totality of the transmission beams in the cycle on the basis of the time offset.Type: GrantFiled: December 23, 2015Date of Patent: May 22, 2018Assignee: PILZ AUSLANDSBETEILIGUNGEN GMBHInventors: Friedjof Tellkamp, Massimo Maffioli, Christoph Werner, Gerhard Braun

Patent number: 9753146Abstract: Spatial intensity distributions of scintillation photons emitted by the scintillator array (5) in response to multiple incident gamma rays in record are recorded (S10). Sets of coincidently emitted scintillation photons from the recorded spatial intensity distributions are determined (S22). The sets of coincidently emitted scintillation photons center-of-gravity positions (S24) and cumulative energies are determined (S26). A clustering analysis based on the determined center-of-gravity positions and cumulative energies to obtain clusters (26a, 26b, 33) of gamma ray events attributed to a scintillator array element is performed (15). A cluster (26a, 26b, 33) of the spatial intensity distributions is cumulated (S29) to determine a cumulative spatial intensity distribution of scintillation photons emitted in response to incident gamma rays in the scintillator array element.Type: GrantFiled: August 13, 2014Date of Patent: September 5, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Christoph Werner Lerche, Poornima Sampath, Torsten Solf
