Publication number: 20150253907Abstract: A touch sensor panel including a plurality of drive lines crossing a plurality of sense lines, forming an array, is disclosed. The plurality of drive lines and the plurality of sense lines are formed by interconnecting a plurality of substantially transparent conductive sections having a first resistivity. A substantially transparent conductive material, with a second resistivity that is lower than the first resistivity, is deposited over at least part of at least one of the plurality of substantially transparent conductive sections of at least one of the plurality of drive lines and the plurality of sense lines. A second layer of the substantially transparent conductive material, with the second resistivity, can be deposited thereafter. At least one dummy section is disposed in an area of the touch sensor panel around the conductive sections of at least one of the plurality of drive lines and the plurality of sense lines.Type: ApplicationFiled: February 5, 2015Publication date: September 10, 2015Inventor: John Greer ELIAS

Patent number: 9041652Abstract: Touch sensitive mechanical keyboards for detecting touch events and key depressions on the keyboard are provided. The keyboard can include a set of individually depressible mechanical keys having a touch sensitive area located on their surface. A touch sensor can be included to detect touch events on the surface of the keys. A keypad can also be included to detect a depression of the mechanical keys.

Patent number: 8928617Abstract: Multi-touch touch-sensing devices and methods are described herein. The touch sensing devices can include multiple sense points, each located at a crossing of a drive line and a sense line. In some embodiments, multiple drive lines may be simultaneously or nearly simultaneously stimulated with drive signals having unique characteristics, such as phase or frequency. A sense signal can occur on each sense line that can be related to the drive signals by an amount of touch present at sense points corresponding to the stimulated drive lines and the sense line. By using processing techniques based on the unique drive signals, an amount of touch corresponding to each sense point can be extracted from the sense signal. The touch sensing methods and devices can be incorporated into interfaces for a variety of electronic devices such as a desktop, tablet, notebook, and handheld computers, personal digital assistants, media players, and mobile telephones.Type: GrantFiled: September 5, 2013Date of Patent: January 6, 2015Assignee: Apple Inc.Inventors: Steven P.

Patent number: 8860693Abstract: Image processing techniques that can improve the user interface experience associated with key-based input devices. In one embodiment, a motion sensitive mechanical keyboard can utilize orthogonally-oriented cameras to sense hand/finger motion over the surface of the keys. This arrangement can enable a standard look and feel mechanical keyboard to receive command and cursor input (e.g., pointing and gestures) from the user without requiring the user to move the user's hand off the keyboard. The image processing techniques can be utilized to minimize or remove undesirable cursor movement that can occur based on certain detected hand/finger motion from such cameras, including looming and/or vertical motions for example.Type: GrantFiled: July 8, 2009Date of Patent: October 14, 2014Assignee: Apple Inc.Inventor: John Greer Elias

Publication number: 20140152619Abstract: Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.Type: ApplicationFiled: February 6, 2014Publication date: June 5, 2014Applicant: Apple Inc.Inventors: Steve Porter HOTELLING, Wei Chen, Christoph Horst Krah, John Greer Elias, Wei Hsin Yao, John Z.
