METHOD AND APPARATUS PERTAINING TO THE TIMING OF STYLUS LOCATION TRANSMISSIONS

摘要

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 Bluetooth.Tm.-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.
