Patent number: 8736115Abstract: Electronic devices may use buttons to gather user input. Button status monitoring circuits may be provided that apply a time-varying bias voltage to each button. The time-varying bias voltage may be held at a fixed non-zero level when the state of the button is being monitored and may be held at a level of zero volts when the state of the button is immaterial and is not being monitored. The reduction of the bias voltage across the button when the button is not being monitored prevents undesired acceleration in dendritic growth when the electronic device is exposed to moisture. The bias voltage may be pulsed by using a control circuit. The control circuit may generate a series of square wave pulses that are applied across the terminals.Type: GrantFiled: April 26, 2011Date of Patent: May 27, 2014Assignee: Apple Inc.Inventors: Joseph Fisher, Jr., Stephen Brian Lynch, Robert Caston Curtis

Patent number: 8717199Abstract: 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: June 4, 2013Date of Patent: May 6, 2014Assignee: Apple Inc.Inventors: John Benjamin Filson, Stephen Brian Lynch, Emery Sanford, Pinida Jan Moolsintong
