20130082936 | SENSOR ARRAY WITH HIGH LINEARITY - A sensor array includes a plurality of pixel sensor circuits; and a current-mode readout circuit to sample signals generated in each pixel sensor circuit; and addressing circuitry to individually select each pixel sensor circuit. Each pixel sensor circuit includes: a transducer and an amplifying element coupled to the transducer and configured to output a signal current which varies as a function of a measured physical property. The current-mode readout circuit includes: a sense signal line coupled to each of the amplifying elements in order to monitor the voltage presented across the amplifying element of the selected pixel sensor circuit; a drive signal line coupled to an output of each of the amplifying elements in order to provide a constant bias voltage to the amplifying element of the selected pixel sensor circuit; and a current conveyor circuit coupled to the sense signal line and drive signal line. | 04-04-2013 |

20140009428 | CAPACITIVE TOUCH PANEL WITH HEIGHT DETERMINATION FUNCTION - A capacitive touch sensor includes a sensor substrate and an array of electrode elements formed over the sensor substrate. Each electrode element of the array includes at least one of a first electrode group comprising at least two drive electrodes and at least one sense electrode, or a second electrode group comprising at least two sense electrodes and at least one drive electrode. The respective electrodes of the first or second electrode group are arranged to form multiple capacitances over different coupling distances. A controller is operatively coupled to the array of electrode elements, the controller configured to determine a distance of an object relative to the surface of the touch sensor based on variations in the multiple capacitances. | 01-09-2014 |
20140062933 | CAPACITIVE TOUCH PANEL WITH A 'DUAL LAYER' FORCE SENSOR - A capacitive touch panel includes a first substrate and a second substrate arranged relative to the first substrate. A plurality of drive electrodes are arranged on the first substrate, wherein each drive electrode comprises a first drive electrode section and a second drive electrode section. In addition, a plurality of sense electrodes are arranged on the second substrate, the plurality of sense electrodes including touch sensing electrodes and force sensing electrodes. At least part of a sense electrode of the plurality of sense electrodes forms a force sensitive coupling capacitance with a second drive electrode section and not with a first drive electrode section. | 03-06-2014 |
20140062934 | CAPACITIVE TOUCH PANEL WITH FORCE SENSING - A capacitive type touch sensing device includes a first electrode array including a plurality of drive electrodes and a plurality of sense electrodes, and a second electrode array spaced apart from the first electrode array and including a plurality of discrete, electrically floating conductive regions. At least part of the second electrode array positionally overlaps with at least part of the first electrode array to define a separation distance therebetween, the separation distance varying with a force applied to a surface of the touch sensing device. Further, each conductive region is positioned relative to a respective drive electrode and sense electrode of the first electrode array so that a capacitance between certain pairs of drive and sense electrodes is more sensitive to a variation in the separation distance than a capacitance between other pairs of drive and sense electrodes. | 03-06-2014 |

20150179122 | DISCRIMINATIVE CAPACITIVE TOUCH PANEL - A mutual capacitance touch sensor includes a substrate, and an array of electrode elements formed on the substrate. Each electrode element includes at least one of a first electrode group having at least two drive electrodes and at least one sense electrode, or a second electrode group having at least two sense electrodes and at least one drive electrode. The respective electrodes of the first or second group are arranged to form multiple capacitances over different coupling distances. A controller is operatively coupled to the array of electrode elements, the controller configured to assign an input object as a conductive object when measurements of the multiple capacitances decrease as the input object approaches the touch sensor, and assign the input object as non-conductive object when measurements of at least one of the multiple capacitances increase as the input object approaches the touch sensor. | 06-25-2015 |
