摘要： A low-latency touch sensitive device provides a method for determining a location of a touch event thereon. The touch sensitive device row conductors and column conductors, the path of each of the row conductors crossing the path of each of the column conductors. Each of a set of orthogonal row signals are simultaneously transmitted on a respective one of at least some of the row conductors and an amount of each of the plurality of orthogonal row signals present on each of the plurality of column conductors is detected. A set of orthogonal column signals are simultaneously transmitted on a respective one of at least some of the column conductors. An amount of each of the orthogonal column signals present on each of the plurality of row conductors is detected. The detected amount of each of the plurality of orthogonal row signals and the detected amount of each of the plurality of orthogonal column signals is used to determine the location of a touch event on the device.

摘要： Light emitting elements and light sensing elements are located on the surface of an object. Surface changes of the object are able to be determined by measuring light received at the light sensing elements. Changes with respect to the emission of the light normal to the surface of the object are used to determine changes in the surface.

摘要： A touch sensor is provided with different operational modes. One mode may be the operation of the touch sensor with a reduced set of transmitting rows than another mode. Transmitting on a reduced set of rows from the normal set of transmitting rows provides an operational mode that is able to detect touch events at greater distances from the touch surface than when a full set of transmitting rows is being driven.

摘要： Disclosed are touch sensitive devices and methods of responding to hits in touch sensitive devices that include a graphical user interface having interface elements, each associated with a program element. A hit test map updater is used to process graphical user interface information into a hit test map in connection with the rendering of the graphical user interface, such that the hit test map associates properties with interface elements appearing on the graphical user interface. An input processor is used to receive a location corresponding to an input in connection with an input event, search the hit test map in which values are associated with interface elements appearing in the graphical user interface, and identify a property of the interface element from the values. In an embodiment, the identified property is proved to a central processing system and a user interface event is generated. In an embodiment, the properties received from the hit test map updater and the input processor are used to determine a program element associated with the property, and the program element is signaled. In an embodiment, the identified property is processed to determine a change to the graphical user interface, and the change is displayed.

摘要： Disclosed are systems and methods for decreasing latency between an acquisition of touch data and processing of an associated rendering task in a touch sensitive device having a touch sensing system capable of producing touch data at a touch sampling rate and having a display system that displays frames at a refresh rate. In an embodiment, the system estimates at least one of (a) a period of time for sampling touch data from the touch sensing system, (b) a period of time for computing touch event data from sampled touch data, and (c) a period of time for rendering of a frame to a frame buffer. The system determines a period of time Tc for (a) sampling touch data from the touch sensing system, (b) computing touch event data from sampled touch data, and (c) rendering of a frame to a frame buffer, based at least in part on the estimate. The system determines a point in time Tr at which the display system will be refreshed from the frame buffer. A sampling start time is computed based at least in part upon Tr and Tc. Sampling of the touch sensing system is initiated to obtain sampled touch data at the sampling start time. Touch event data is computed from the sampled touch data, and a frame that reflects the touch event data is rendered to the frame buffer prior to the time Tr. The display is then refreshed from the frame buffer.

摘要： A sensor is located within a vehicle that is able to determine pressure and location of an occupant or object. The sensor is able to take measurements during static conditions and situations where an object or occupant is moving due to the movement of, for example, a vehicle. The measurements taken during movement and during the static conditions and are used in order to enhance and refine the results of measurements that would be obtained if the measurements were taken alone.

In an embodiment, a choke is used to mitigate infusion signals in other parts of a body. The infusion signal source is configured to transmit differing, orthogonal signals to the two infusors. In an embodiment, each of the differing signals is made up of at least a high frequency signal and a low frequency signal. In an embodiment, the high frequency signal and the low frequency signal are at least one octave apart and orthogonal to each other.

摘要： Methods are disclosed for dynamic assignment of possible channels in a touch sensitive device having rows and columns. In an embodiment, a method determines a first signal space in which to generate signals for use in the touch sensor. Signals are then generated in the first signal space on separate ones of the rows and a column signal is sensed on a column. The first signal space is replaced with a second signal space, and a second plurality of signals is generated for use in the touch sensor in the second frequency space. The second plurality of signals is sensed to identify a touch event in the touch sensitive device.
