    摘要: A system comprising a sensing device and a capacitive sense array configured to track the position of a stylus and synchronize the capacitive sense array to the stylus transmit signal. The system is configured to track the position of both a stylus and a passive touch object. The system is further configured to track the position of the stylus using self capacitance sensing and track the position of the passive touch object using mutual capacitance sensing. The system further configured to modulate the stylus transmit signal to include additional data to support additional stylus functions.

    摘要: A method for locating a conductive object at a touch-sensing surface may include detecting a first resolved location for the conductive object at the touch-sensing surface based on a first scan of the touch-sensing surface, predicting a location for the conductive object, and determining a second resolved location for the conductive object by performing a second scan of a subset of sensor elements of the touch-sensing surface, wherein the subset of sensor elements is selected based on the predicted location of the conductive object.

    摘要: A pixel structure having a shielded storage node. A pixel comprises a sample transistor coupled to a light detecting stage. The sample transistor comprises an inner junction region surrounding and coupled to a storage node and a gate disposed around at least three sides of the inner junction region that operates as a charge barrier to shield the storage node. A memory capacitor is coupled to the storage node.

    摘要: A circuit for a pixel site in an imaging array includes a pixel (11 of Figure 7) to convert incident light to an electrical signal; a column or row line (23 of Figure 7) to read out a voltage from the pixel; a column or row line transistor (225 of Figure 7), operatively connected between one end of the column or row line and a predetermined voltage, to reset a voltage associated with the column or row line; and a reset voltage generator (2150 of Figure 7), operatively connected to the column or row line transistor, to generate reset pulses. The reset voltage generator (2150 of Figure 7) generates a first reset pulse at a beginning of an integration period of the pixel. The reset voltage generator (2150 of Figure 7) generates a second reset pulse after generating the first reset pulse, the generation of the second reset pulse being at an end of the integration period of the pixel. A pixel voltage of a column or row line is measured by hard resetting the column or row line voltage to a first predetermined voltage; soft resetting the column or row line voltage to a first pixel voltage; hard resetting the column or row line voltage to a second predetermined voltage; soft resetting the column or row line voltage to a second pixel voltage; and determining a difference between the first and second pixel voltages, the difference being the measured pixel voltage.
