20150256329 | SYSTEM AND METHOD FOR IMPROVED SYNCHRONIZATION BETWEEN DEVICES - A system and method for synchronizing two devices in communication with each other. When communication between the two devices is to be established, a synchronization process may be invoked. In an embodiment, a first device may initiate sending synchronization signals having rising edge and falling edge pairs. The second device may include a controller configured to receive the synchronization signals. However, noise may inhibit the ability of the controller to correctly receive and/or interpret the synchronization signals. Noise may cause detection components to falsely detect noise as a synchronization signal or may cause detection components to miss detection of an actual synchronization signal. A window generator may be used to generate comparison windows for the controller to detect synchronization signals. Further, the detection window duration and start times may be adjusted based on previously detected (or undetected) synchronization signals in order to compensate for noise overshadowing synchronization signals. | 09-10-2015 |
20150256330 | SYSTEM AND METHOD FOR PHASE ERROR COMPENSATION IN SYNCHRONIZED DEVICES - A system and method for compensating for detected phase errors during communications between synchronized devices. In an embodiment, the two devices may be a touch screen device and a synchronized stylus device. To this end, the touch screen device includes a controller configured to receive data signals from the stylus at specific time intervals. The touch screen device generates an internal control signal for receiving the incoming data signals at an expected frequency. The touch screen device further includes circuitry for measuring differences in the time a data signal is actually received against when the data signal was expected to be received and determines a time difference (e.g., a phase error). Then, the internal control signal may be adjusted to compensate for the accumulated phase error. Such a measurement and compensation helps ensure that communications remain in synchronization without having to reestablish synchronization through a cumbersome synchronization process. | 09-10-2015 |
20160048234 | SYSTEM AND METHOD OF COMMUNICATION BETWEEN A CAPACITIVE TOUCH SCREEN AND AN ACTIVE STYLUS - An active stylus is capacitively coupled to a capacitive touch panel for communication.

In response to such receipt, the active stylus synchronizes to a repeating communications frame implementing time division multiplexing. Communications from the active stylus to the panel include: information communications; synchronization communications and communications specific for columns and/or rows of the panel. Communications from the panel to the active stylus may be addressed uniquely to the stylus or commonly to a group of styluses. | 02-18-2016 |
