Patent number: 10042459Abstract: The disclosed embodiments relate to a system that provides power for a touch-enabled display, wherein the touch-enabled display cycles between a display mode and a touch mode. During the display mode, the system drives a display-mode voltage to the touch-enabled display through a power output, wherein the power output is coupled through a display-mode capacitor CD to ground. Next, during a transition from the display mode to the touch mode, the system couples the power output through a touch-mode capacitor CT to ground, wherein CT was previously charged to a touch-mode voltage, which causes the power output to rapidly transition to the touch-mode voltage. Then, during the touch mode, the system drives the touch-mode voltage through the power output.Type: GrantFiled: September 8, 2015Date of Patent: August 7, 2018Assignee: Apple Inc.Inventors: Christoph H.

Publication number: 20180077021Abstract: A network switch having a plurality of ports may be configured with a plurality of wake domains, which may be independently transitioned between at least a wake state and a sleep state. For example, one or more wake domains may transition between a wake state and a sleep state while one or more other wake domains do not change state. The ports included in each of the wake domains may be dynamically configurable. In this way, power may be conserved by operating a subset of the plurality of ports in the wake state, while other ports remain in the sleep state. In some embodiments, the wake domains may be prioritized, such that, upon a simultaneous command, a higher-priority wake domain may be awakened before a lower-priority wake domain. In this way, high-priority ports may be awakened in less time than would be required to awaken the entire network switch.Type: ApplicationFiled: September 5, 2017Publication date: March 15, 2018Inventors: Koussalya Balasubramanian, Robert B. Boatright, Kevin J. White

Patent number: 9864445Abstract: Touch screens with more compact border regions can include an active area that includes touch sensing circuitry including drive lines, and a border region around the active area. The border region can include an area of sealant deposited on conductive lines, and transistor circuitry, such as gate drivers, between the active area and the sealant. The conductive lines can extend from the sealant to the active area without electrically connecting to the transistor circuitry. The conductive lines can have equal impedances and can connect the drive lines to a touch controller off of the touch screen. A set of drive signal characteristics for the drive lines can be obtained by determining a transfer function associated with each drive line, obtaining an inverse of each transfer function, and applying a set of individual sense signal characteristics to the inverse transfer functions to obtain the corresponding set of drive signal characteristics.Type: GrantFiled: February 20, 2015Date of Patent: January 9, 2018Assignee: Apple Inc.Inventors: Marduke Yousefpor, Steven P.

Patent number: 9760195Abstract: Reducing or eliminating the effects of noise that can be generated by a power system of a touch screen device, such as a gate line voltage system that applies voltage to gate lines of the touch screen, is provided. In one example, a power supply, such as a charge pump, can be disabled during active touch sensing, such that noise from the charge pump is not generated during touch sensing. In some examples, a voltage regulator can help to maintain the gate voltage level at or above a desired threshold. In some cases, noise entering the touch sensing system can have a lasting effect on noise-sensitive components, even after the noise source is disabled. In these cases, a post-noise stabilizing system can be included to stabilize, reset, etc., noise-sensitive components of the touch sensing system, which can help to reduce or eliminate the lasting effect of noise.Type: GrantFiled: September 23, 2011Date of Patent: September 12, 2017Assignee: Apple Inc.Inventors: Christoph Horst Krah, Kevin J.

Patent number: 9535544Abstract: A touch screen to reduce touch pixel coupling. In some examples, the touch screen can include a first display pixel and a second display pixel in a row of display pixels, where the first display pixel can be configurable to be decoupled from the second display pixel during at least a touch sensing phase of the touch screen. In some examples, the touch screen can include a display pixel having a first and a second transistor, where the second transistor can be electrically connected to a gate terminal of the first transistor, and can be diode-connected. In some examples, the touch screen can include two display pixels, each display pixel having two transistors, where two of the transistors can be electrically connected to a first gate line, and the remaining two transistors can be individually electrically connected to a second and third gate line, respectively.Type: GrantFiled: May 31, 2013Date of Patent: January 3, 2017Assignee: Apple Inc.Inventors: Marduke Yousefpor, Taif Ahmed Syed, Ahmad Al-Dahle, Kevin J.
