摘要： A data frame in a touch capacitive sensing circuit includes both mutual capacitance data and self capacitance data. The mutual capacitance data and self capacitance data of the frame are filtered to define mutual capacitance and self capacitance islands. Centroids of the mutual capacitance and self capacitance islands are calculated and then processed in a weighted mixing operation to produce a hybrid centroid that more accurately locates the coordinates of a detected touch/hover.

摘要： An electronic device disclosed herein includes a touch screen controller to identify an island i.e., a matrix of acquired touch data values, the island including adjacent touch data values indicating a potential touch of a touch sensitive screen. A first sharpness of the island is calculated using a first normalization type and not a second normalization type. A second sharpness of the island is calculated using the first and second normalization types if the first sharpness is greater than the sharpness threshold. A dynamic variance threshold is determined as a function of the second sharpness. A dynamic strength threshold is determined as a function of the second sharpness if a variance of the island is greater than the dynamic variance threshold, and the island is determined to be a valid stylus island if the peak strength is greater than the dynamic strength threshold.

摘要： A circuit includes a counter circuit, a logic circuit, and a clock divider. The counter circuit includes a clock divider counter to be loaded with most significant bits of a divider value, and decremented at a same edge of each pulse of a clock signal. The logic circuit compares a value contained in the divider counter to a reference value and generates an end count signal as a function of the value contained in the divider counter matching the reference value, and transitions a toggle signal at a same edge of each pulse of the end count signal. The clock divider counter is reloaded with the most significant bits of the divider value as a function of the end count signal. The clock divider generates a divided version of the clock signal as a function of the toggle signal.

摘要： A touch screen controller includes input circuitry receiving touch data from a touch screen, and processing circuitry. The processing circuitry determines first coordinates of a touch at a first time, based upon the received touch data. A first threshold window is set about the first coordinates, with the first threshold window having a central point at the first coordinates, and a second threshold window is set about the first coordinates, with the second threshold window having a central point at the first coordinates and being larger than the first threshold window. Second coordinates of the touch are determined at a second time, based upon the received touch data, and where the second coordinates are not within the first threshold window but are within the second threshold window, the second coordinates are corrected based upon a distance between the second coordinates and the central point of the second threshold window.

摘要： A touch screen controller disclosed herein includes a circuit configured to generate a digital touch voltage comprises of samples, at a base sampling rate. The touch screen controller also includes a digital processing unit configured to analyze a first subset of samples of the digital touch voltage samples to determine noise content thereof, the first subset of samples corresponding to samples at a first investigated sampling rate that is a first function of the base sampling rate. The digital processing unit is also configured to analyze a second subset of samples of the digital touch voltage to determine noise content thereof, with the second subset of samples corresponding to samples at a second investigated sampling rate that is a second function of the base sampling rate, and determine a preferred sampling rate from among the first and second investigated sampling rates as a function of determined noise content thereof.

摘要： A microfluidic-based sensor, comprising: a semiconductor body, having a first and a second side opposite to one another in a direction; a buried channel, extending within the semiconductor body; a structural layer, of dielectric or insulating material, formed over the first side of the semiconductor body at least partially suspended above the buried channel; and a first thermocouple element, including a first strip, of a first electrical conductive material, and a second strip, of a second electrical conductive material different from the first electrical conductive material, electrically coupled to the first strip. The first thermocouple element is buried in the structural layer and partially extends over the buried channel at a first location. A corresponding manufacturing method is disclosed.

摘要： Disclosed herein is a touch screen controller that calculates a variance of an island in acquired touch data values. Where the variance exceeds a variance threshold, the island is validated as a representing touch. Where the variance does not exceed the variance threshold, whether the island represents a touch or a hover is determined by calculating a sharpness by applying weights to nodes of the island, where neighboring nodes adjacent to a peak node are weighted less than non-neighboring nodes not adjacent to the peak node. An island strength threshold is determined as a function of a product of the variance and the sharpness. It is determined that the island represents a touch where a highest touch data value of the island is greater than the island strength threshold, and a hover where the highest touch data value of the island is less than the island strength threshold.

摘要： The present disclosure is directed to a microfluidic die that includes ejection circuitry and one time programmable memory with a minimal number of contact pads to external devices. The die includes a relatively large number of nozzles and a relatively small number of contact pads. The die includes decoding circuitry that utilizes the small number of contact pads to control the drive and ejection of the nozzles and the reading/writing of the memory with the same contact pads.

摘要： A method of compensated touch data values disclosed herein includes acquiring touch data values about a dead sensing zone of a touch screen, and determining a peak value of those touch data values. Then, a new peak value is calculated as a function of an average of the peak value and another value of the touch data value, and a sharpness value for the dead sensing zone is generated if a second highest value of the touch data values is less than the new peak value. Thereafter, compensated touch data values are generated for the dead sensing zone if the second highest value is greater than the new peak value.
