20130194195 | ELECTRONIC DEVICE INCLUDING TOUCH-SENSITIVE DISPLAY - A method includes detecting a touch on a touch-sensitive display, determining a time of a display update of the touch-sensitive display, and adjusting a scanning rate of scanning electrodes of the touch-sensitive display based on the time of the display update. | 08-01-2013 |
20130196596 | COMMUNICATIONS DEVICE AND METHOD FOR HAVING INTEGRATED NFC ANTENNA AND TOUCH SCREEN DISPLAY - A communications device includes a housing and a wireless transceiver and processor carried by the housing and operative with each other. A Near Field Communications (NFC) circuit is carried by the housing and coupled to the processor. A touch screen display is connected to the processor. An NFC antenna is integrated with the touch screen display and coupled to the NFC circuit. | 08-01-2013 |
20130265239 | ELECTRONIC DEVICE AND METHOD OF CONTROLLING DISPLAY OF INFORMATION ON A TOUCH-SENSITIVE DISPLAY - A method includes detecting a touch on a touch-sensitive display of an electronic device, displaying information on the touch-sensitive display utilizing touch data of the detected touch, filtering the touch data to produce filtered data, and updating the information displayed based on the filtered data. | 10-10-2013 |
20130300670 | COMPUTER INPUT STYLUS WITH MULTIPLE ANTENNAS - The present disclosure provides a stylus for enabling inputs to be made to a host electronic device. The stylus has multiple antennas that are displaced from each other and the tip of the stylus body. In operation, the antennas are excited to each radiate an electromagnetic field directed towards the tip of the stylus. The radiated electromagnetic fields may be sensed by the host electronic device to determine the position of the tip relative to a sensing surface. | 11-14-2013 |
20140022218 | ORIENTATION SENSING STYLUS - The present disclosure provides for method and apparatus for controlling an application executed on an electronic device dependent upon the orientation of a stylus. The stylus includes a rotation rate sensor, such as a gyroscope. A signal, dependent on the rotation rate, is transmitted from the stylus and received by the electronic device. The stylus orientation may be determined from the rotation rate using an integration circuit to determine a rotation matrix that is applied to an initial orientation vector. The electronic device may use the stylus orientation to determine the handedness of a user, to control properties of a drawing application, or for other purposes. | 01-23-2014 |
20140038524 | METHOD AND APPARATUS PERTAINING TO THE TIMING OF STYLUS LOCATION TRANSMISSIONS - A stylus includes a stylus housing that contains a location-beacon transmitter, a wireless receiver, and a control circuit that operably couples to the preceding. By one approach the control circuit is configured to use the location-beacon transmitter to transmit signals as a function of at least one signal received via the wireless receiver. The aforementioned wireless receiver can comprise a Bluetoothâ„¢-compatible wireless transceiver that pairs with the corresponding display-based device. The signal received via this wireless receiver can comprise transmission-synchronization information that represents a video-display event for the display-based device such as refreshing the display of the display-based device. In such a case, the signal can comprise a vertical synchronization pulse as sourced by the display-based device. So configured, the stylus can time the transmission of its location-beacon signals to arrive at the display-based device just prior to when the latter refreshes its display. | 02-06-2014 |
20140049479 | SMUDGE EFFECT FOR ELECTRONIC DRAWING APPLICATION - An electronic device, computer-readable medium and method provide for line smudging in electronic drawing. The electronic device has a touch sensitive display screen that is responsive to user touch and stylus input. A graphics module is operable to render a line on the touch sensitive display screen in response to motion of the stylus. If a trajectory of the touch input intersects with the line within a set time period after the line is rendered, the line is replaced by a representation of a smudged line. The electronic device may be controllable by instructions stored on a computer-readable medium. | 02-20-2014 |
20140062898 | METHOD AND APPARATUS PERTAINING TO THE INTERLACING OF FINGER-BASED AND ACTIVE-STYLUS-BASED INPUT DETECTION - A control circuit controls detection of both finger-based input and active-stylus-based input as input via a display. In particular, during a single scan period, the control circuit interleaves use of the finger-detection resources with use of the active-stylus-detection resources. | 03-06-2014 |
20140098071 | Method and Apparatus Pertaining to an Interference-Assessing Stylus - A stylus is configured to use a local wireless receiver to assess interference at a transmission frequency that corresponds to the stylus's location-information wireless transmitter. By one approach, the stylus carries out this assessment during transmission nulls for the location-information wireless transmitter. If desired, the wireless receiver can operably couple to (and hence share) a same antenna that operably couples to the location-information wireless transmitter. By one approach, the stylus is configured to change the transmission frequency of the location-information wireless transmitter as a function of determining that the aforementioned assessed transmission frequency is experiencing more than a predetermined level of interference. | 04-10-2014 |
