Patent number: 10707558Abstract: An electronic device may have wireless circuitry with antennas. An antenna resonating element arm for an antenna may be formed from peripheral conductive structures running along the edges of a device housing. The peripheral conductive structures may form housing sidewalls. A slot may be machined into a metal housing that separates the housing sidewalls from a planar rear housing portion that forms a ground for an antenna. The slot may be filled with plastic filler. A parasitic antenna resonating element arm that supports an antenna resonance at high band frequencies may be embedded within the plastic filler. The parasitic antenna resonating element may be formed from a portion of the planar rear housing portion.Type: GrantFiled: December 11, 2017Date of Patent: July 7, 2020Assignee: Apple Inc.Inventors: Hongfei Hu, Benjamin Hane Bustle, Enrique Ayala Vazquez, Nanbo Jin, Miguel Christophy, Erdinc Irci, Salih Yarga, Erica Tong, Anand Lakshmanan, Mattia Pascolini, Tyler Cater, Christopher T.

Patent number: 10707032Abstract: Electronic devices having input structures that are operative to translate a relatively small travel of an input surface to a larger travel elsewhere. For example, force exerted on an input surface of an input body may cause a corresponding input body to move a first distance. An arm, lever mechanism, or the like may have an end or other portion that moves a second distance in response to the input body's motion. The second distance may be greater than the first; in some embodiments, the second distance may be an order of magnitude or more than the first distance. The travel may close or open a switch in response to the force exerted on the input surface.Type: GrantFiled: December 1, 2017Date of Patent: July 7, 2020Assignee: APPLE INC.Inventors: Colin M. Ely, Daniel William Jarvis, Benjamin J. Pope, Erik G. de Jong, Tyler S. Bushnell, Christopher T. Cheng, Trevor J. Ness, William C. Lukens, Steven P. Cardinali, Robert D. Turner

Patent number: 10643339Abstract: An apparatus, system and method is provided to determine a motion of pixels in local regions of a scene, classify the motion into a speed category, and make decisions on how to render blocks of pixels. In one implementation the motion in a tile is classified into at least three different speed regimes. If the pixels in a tile are in a quasi-static speed regime, a determination is made whether or not to reuse a fraction of pixels from the previous frame. If the pixels are determined to be in a high speed regime, a decision is made whether or not a sampling rate may be reduced.Type: GrantFiled: March 6, 2018Date of Patent: May 5, 2020Assignee: Samsung Electronics Co., Ltd.Inventors: Abhinav Golas, Karthik Ramani, Christopher T.

Patent number: 10461429Abstract: A consumer electronic product includes a switchable inductor array coupled to the RF antenna, the switchable inductor array comprising inductive elements and a switch circuit coupled to the inductor array to select at least one of the inductive elements and couple the selected inductive element with the RF antenna. The product can further include an assembly having a mesh that is strengthened by a stiffener. A multi-layer adhesive have a conductive layer that can be used to shield the RF antenna and adhesive layers that can provide adhesion between the stiffener and the housing of the product. The assembly can be covered by a cowling that is made of metal to provide further shielding. To reduce potential coupling between the RF antenna and the cowling, the cowling can have a portion that is formed of plastic to distance its metal portion from the antenna.Type: GrantFiled: March 16, 2017Date of Patent: October 29, 2019Assignee: Apple Inc.Inventors: Christopher J.
