20100188345 | CONDUCTIVE MULTI-TOUCH TOUCH PANEL - A conductive multi-touch touch-sensitive panel includes two intersecting but electrically isolated arrays of linear conductors which can be brought into electrical contact by touching the panel. A display element may be positioned beneath the two arrays of linear conductors to provide a touchscreen panel. A touch to a cover plate or member causes one or more linear conductors in one array to contact one or more linear conductors in the other array. The location of a touch to the panel can be detected by individually or sequentially applying an electrical signal, such as a voltage or current, to each linear conductor in one array while sensing voltage or current on each of the linear conductors in the other array. | 07-29-2010 |
20120105358 | FORCE SENSING TOUCH SCREEN - A computing device includes a touch screen display with a plurality of force sensors, each of which provides a signal in response to contact with the touch screen display. Using force signals from the plurality of force sensors, a characteristic of the contact is determined, such as the magnitude of the force, the centroid of force and the shear force. The characteristic of the contact is used to select a command which is processed to control the computing device. For example, the command may be related to manipulating data displayed on the touch screen display, e.g., by adjusting the scroll speed or the quantity of data selected in response to the magnitude of force, or related to an operation of an application on the computing device, such as selecting different focal ranges, producing an alarm, or adjusting the volume of a speaker in response to the magnitude of force. | 05-03-2012 |
20120116672 | HAPTIC BASED PERSONAL NAVIGATION - A mobile platform includes one or more haptic feedback elements that are positioned in regions of the mobile platform that are proximate to a facial region of a user while the user holds the mobile platform to an ear. By way of example, the haptic feedback elements may be electric force elements that overlay a display or vibrating or thermal elements. The mobile platform is capable of determining a current location and receiving a desired location, which may be, e.g., a location provided by the user, a location with superior signal strength or of another mobile platform. The mobile platform determines directions from the present location to the current location and translates the direction in to control signals. Haptic signals are produced to the facial region of the user by the haptic feedback elements in response to the control signals, thereby providing the directions to the user. | 05-10-2012 |
20130039507 | ELECTRONIC DEVICES FOR CONTROLLING NOISE - An electronic device for controlling noise is described. The electronic device includes a force sensor for detecting a force on the electronic device. The electronic device also includes noise control circuitry for generating a noise control signal based on a noise signal and the force. Another electronic device for controlling noise is also described. The electronic device includes a speaker that outputs a runtime ultrasound signal, an error microphone that receives a runtime ultrasound channel signal and noise control circuitry coupled to the speaker and to the error microphone. The noise control circuitry determines at least one calibration parameter and determines a runtime channel response based on the runtime ultrasound channel signal. The noise control circuitry also determines a runtime placement based on the runtime channel response and the at least one calibration parameter and determines at least one runtime active noise control parameter based on the runtime placement. | 02-14-2013 |
20140098969 | MULTI-PIN PLUG WITH EXPANSION NUB - Flexible connectors that can be mated into specially designed electronic receptacles are described. In some embodiments, additional connections on the connector can make contact with the receptacle. However, the additional connections are also provided in a manner wherein if the connector is plugged into a legacy, conventional receptacle, the additional connectors become disengaged and slide away from, back from, or inside the jack so that the connector can still be used on legacy devices. | 04-10-2014 |

20150062020 | SYSTEM AND METHOD FOR IMPROVED PROCESSING OF TOUCH SENSOR DATA - Implementations disclosed herein provide systems and methods for improved processing of touch sensor data with improved scalability and reduced standby power. Touch-related algorithms may be partitioned between the touch screen controller and the application processor or host such that the system can function with low standby power and low interface bandwidth while providing a scalable solution for enhanced user experience. In some aspects, a small digital processing engine and memory remains in the analog front end (AFE) of the touch screen controller to perform imagine forming algorithms that are mostly related to noise reduction and filtering schemes. | 03-05-2015 |
