20140062970 | Tuning Algorithm for Noise Reduction in an Active Stylus - In one embodiment, a stylus receives a signal, the stylus being able to wirelessly transmit signals to and receive signals from a device, and the stylus having a plurality of electrodes disposed in a tip of the stylus. The stylus compares a first value of the signal to a first threshold and determines whether to start a timing period based at least in part on this comparison. If the timing period is started, the stylus compares a second value of the signal to a second threshold and determines whether to stop the timing period based at least in part on this second comparison. If the timing period is stopped, the stylus determines whether the duration of the timing period is within a pre-determined range of timing period values. If so, the stylus processes the signal. | 03-06-2014 |
20140160036 | Sending Drive Signals with an Increased Number of Pulses to Particular Drive Lines - In one embodiment, a method includes detecting a touch of an object on a device. The method also includes predicting an area of the device that the detected touch will move to. The method further includes sending a first set of drive signals to one or more drive lines within the predicted area, the first set of drive signals each having a first number of pulses. The method further includes sending a second set of drive signals to one or more drive lines outside the predicted area, the second set of drive signals each having a second number of pulses. Furthermore, the first number of pulses is greater than the second number of pulses. | 06-12-2014 |
20140340359 | Selective Scan of Touch-Sensitive Area for Passive or Active Touch or Proximity Input - In certain embodiments, an apparatus includes a touch sensor that includes a touch-sensitive area and a touch-sensor controller. The touch-sensor controller is operable to: select a first region around a determined first location associated with an object within the touch-sensitive area, select a second region around the determined first location associated with the object within the touch-sensitive area, and scan two or more electrodes within the first region and two or more electrodes within the second region to determine a second location associated with the object within the touch-sensitive area. | 11-20-2014 |
20150035810 | Active Stylus with High Voltage - In certain embodiments, a stylus includes one or more electrodes and one or more computer-readable non-transitory storage media embodying logic for transmitting signals wirelessly to a device through a touch sensor of the device. At least some of the signals are high-voltage signals generated by a relatively large potential difference compared to a voltage within a voltage range of approximately 1 to approximately 3 volts. The stylus includes a stylus tip, and one or more of the one or more electrodes are disposed at the stylus tip. | 02-05-2015 |
