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.

Abstract: 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.

Abstract: 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.

Abstract: An infusion system including two infusors is operatively connected to a source of infusion signals. In an embodiment, the infusors being adapted for attachment to different parts of the same hand of a user. In an embodiment, the infusors are embedded in a glove or other wearable component. 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. In an embodiment, the infusion system includes a steering wheel sensor made from a plurality of conductors attached to a receiver.

Abstract: 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.

Abstract: Differential transmission is provided in a capacitive sensor for reducing cross-talk between rows and columns. A capacitive touch sensitive device as disclosed herein includes row conductors and column conductors, a first row signal generator for transmitting a first row signal on a first row conductor, a second row signal generator for transmitting a second row signal on a second row conductor, and a touch processor for identifying a touch event on the touch interface by processing signals present on at least one of the column conductors. The first and second row signals together form a differential row group of signals that cancel each other out or at least substantially mitigate each other so as to reduce cross-talk interference in the sensor.

Abstract: In an embodiment, a touch surface, such as a GUI is graphically divided into two or more input regions, and based on this division, input event paths from a single sensor can be integrated within an operating system to provide application developers with the ability to easily and effectively filter there-between. The graphical division allows an application developer to specify which elements of a given GUI take one path, versus another. In an embodiment, low-latency and high-latency event paths are provided; an algorithm takes into consideration input regions and, based on those regions, handles the low- and high-latency input event paths in a computer system, directing the appropriate inputs through the appropriate processing, and directing the output to the appropriate process or queue without creating constraints on the low-latency event processing due to the presence of higher-latency event paths for a given sensor.

Abstract: A system and method for determining location of a touch event on or in proximity to a touch sensitive device is disclosed. The touch sensitive device includes row conductors and column conductors that each only transmit or receive signals during a given frame. Each of the orthogonal row signals is transmitted on a respective one of at least some of the row conductors. Signals are received on each of the column conductors an amount of each of the row signals present on each of the plurality of column conductors is detected. Orthogonal column signals are transmitted on the column conductors. Signals are received on each of the row conductors and an amount of each of the orthogonal column signals present on each of the row conductors is detected. The detected amount of each of the orthogonal row signals and the detected amount of each of the orthogonal column signals is used to determine a location of a touch event on or in proximity to the touch sensitive device. At least one of the transmitting and receiving steps avoids simultaneously transmitting and receiving on at least one of the row conductors or column conductors.
