Abstract:
1. A system for asynchronously identifying an item within a sensing volume comprises: a plurality of object sensors, each object sensor configured and arranged to determine at least one parameter describing objects as they are relatively moved with respect to the sensing volume, and having a known position and attitude with respect to the sensing volume, each parameter not including system clock information; a position sensor, configured and arranged to produce position information relating to the relative movement, wherein the position information does not comprise system clock information; a processor, configured and arranged to receive the parameters from the object sensors and to associate the parameters with respective ones of the objects on the basis of the position information and on the basis of the known position and attitude of the object sensor that determined each respective parameter, the association of respective parameters with respective objects being performed without taking into account system clock information, and to, for each object having at least one associated parameter, compare the at least one associated parameter to known item parameters to assign an item identification to the object.
