Patent number: 9431189Abstract: Configurable buttons for electronic devices such as portable electronic devices are provided. A configurable button may have a button member that moves relative to a device housing when it is desired to activate a switch. The button may have an associated touch sensor. The touch sensor may detect when a user's finger touches a particular portion of the button member. Contact with only this portion of the button member is generally inadvertent, so an actuator may be used to prevent or otherwise restrict motion of the button relative to a device housing. This prevents inadvertent activation of the button when a user is manipulating portions of an electronic device such as clip or lid, but does not intend to depress the button.Type: GrantFiled: May 6, 2014Date of Patent: August 30, 2016Assignee: APPLE INC.Inventors: John Benjamin Filson, Stephen Brian Lynch, Emery Sanford, Pinida Jan Moolsintong

Patent number: 9413196Abstract: A revised coil loop structure is combined with metamaterials designed to contain and redirect the electromagnetic field to produce an improved inductive coupling system. The efficiency of the inductive power transfer system is increased relative to existing technologies by overcoming the negative effects of distance and misalignment. The transmitting and receiving coils are both constructed by connecting a series of printed circuit boards (PCBs). The individual PCBs are then stacked on top of one another and connected to produce the transmitting and receiving coils. The transmitting and receiving coils further feature a coil shape designed to allow the coils to be actively and variably tuned to one another. The efficiency of power transfer in the system is additionally increased through the use of metamaterials. The metamaterial is used as a backing for the coils and reduces the amount of magnetic flux found on the back of the coils.Type: GrantFiled: April 9, 2012Date of Patent: August 9, 2016Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Jae Seung Lee, Paul Donald Schmalenberg
