An integrated wireless-global positioning system determines the location of a wireless terminal from satellite measurements and wireless network measurements. The touch panel detects contact with respect to a surface thereof. The synchronous network operates on a network master clock rate with a frequency that may be higher, lower or equal to the source sample rate. High quality structures may also be cut out from the workpiece. For each link in the VLAN, the count of access switches on the first side of the link is multiplied by the count of access switches on the second side of the link to derive a count of paths that include the link.
