摘要： A system and method for classifying touches input into a four-wire resistive touch screen is presented. A voltage may be applied to electrodes in a layer making it the active layer. A first set of four voltages may be measured by a voltage sensing circuit from electrodes in the active layer of a touch screen and a passive layer of a touch screen. The voltage may be switched from electrodes of the first layer to the electrodes of the second layer. A voltage sensing circuit may measure a second set of four voltages nearly simultaneously from electrodes in the active layer and the passive layer of a touch screen. Each set of measured voltages from the passive layer and or the active may be processed. A rule set may be applied to the processing results. An indication of the type of touch that was applied to the touch screen may be provided and optionally including quantitative results.

摘要： A system and method is provided for a high accuracy digital temperature sensor (DTS). The system includes a differential analog temperature sensor based on bipolar junctions, providing an output signal obtained as the difference between the VBE of two bipolar junctions. This signal is converted into the digital domain and compared to N−1 threshold digital values for providing piece-wise linear error correction for the variations with temperature of the different error sources within the DTS. This system and method advantageously improve the accuracy of a DTS over an extended temperature range.
