Abstract
A location system comprises a plurality of transponders whose locations are detectable by a base system. The base system interrogates (-) the transponders one at a time in accordance with a schedule of consecutive time slots. In response to a priority request received () from one of the transponders, the base system interrupts the schedule and interrogates substantially immediately () the signaling transponder so as to determine its location with minimal latency.
