摘要： A mutual capacitive touch sensing device is disclosed. The device can include nodes for sensing a touch at the device and for sensing a force applied to the device. Some nodes can perform both touch and force sensing; while other nodes can perform touch sensing. The device can include distinct individual drive lines for driving the nodes and separate distinct individual sense lines for transmitting touch or force signals from the nodes. The nodes can form groups, where the nodes in each group can be coupled to the same drive line and to different sense lines and where each node in a group can be coupled to a node in a different group by the same sense line. Each node can be set up with a different combination of drive and sense lines coupled thereto. An example device can be a click wheel.

摘要： A signal-processing circuit for a dual-axis vibratory rotation-rate sensor has a digitally programmable bandwidth. An analog-to-digital converter (ADC) converts analog sense signals to digital signals at a high sampling rate. The results of successive ADC conversions are accumulated for a user-programmable number of conversions. By accumulating a number of samples, the sense signals are averaged which improves the signal-to-noise ratio and smoothes the output signal. Alternatively, accumulating a smaller number of samples allows the user to improve the response time of the sensor, allowing the user to set the number of samples that are averaged enables the user to control the effective bandwidth of the sensor. The accumulated conversions are also are scaled by unit-specific calibration factors in order to accommodate for unit to unit variations, so that the rate output will be consistent across a number of sensors.

摘要： Normalization of regions of a sensor panel capable of detecting multi-touch events, or a sensor panel capable of detecting multi-hover events, is disclosed to enable each sensor in the sensor panel to trigger a virtual button in a similar manner, given the same amount of touch or hover. Each sensor produces an output value proportional to the level or amount of touch or hover. However, due to processing, manufacturing and physical design differences, the sensor output values can vary from region to region or panel to panel for a given amount of touch or hover. To normalize the sensor output values across regions, gain and offset information can be obtained in advance, stored in nonvolatile memory, and later used to normalize the sensor output values so that all regions in the sensor panel can trigger virtual buttons similarly, providing a uniform “response function” at any location on the sensor panel.

摘要： Reconstruction of an original touch image from a differential touch image is disclosed. Reconstruction can include aligning columns of the differential touch image relative to each other and aligning the image to a baseline DC value. The column and baseline alignment can be based on the differential image data indicative of no touch or hover, because such data can more clearly show the amount of alignment needed to reconstruct the original image. The reconstruction can be performed using the differential image data alone. The reconstruction can also be performed using the differential image data and common mode data indicative of the missing image column average.

摘要： Reduction of the effects of differences in parasitic capacitances in touch screens is provided. A touch screen can include multiple display pixels with stackups that each include a first element and a second element. For example, the first element can be a common electrode, and the second element can be a data line. The display pixels can include a first display pixel including a third element connected to the first element, and the third element can contribute to a first parasitic capacitance between the first and second elements of the first display pixel, for example, by overlapping with the second element. The touch screen can also include a second display pixel lacking the third element. The second display pixel can include a second parasitic capacitance between the first and second elements of the second display pixel. The first and second parasitic capacitances can be substantially equal, for example.
