Abstract
A method of selectively addressing one or more transponders in a set (17) of transponders (21, 22, 23, 24, 25) is described. The method comprise transmitting a first set of one or more commands (25; 251, 252) selected to be not executable by a first subset (24; 242) of transponders or to be executable in a shorter time by the first subset of transponders than by a second subset of transponders (23; 231, 232) in the set, and transmitting a second set of one or more commands (26; 253) such that the second set of commands are received by the transponders while the second subset of transponders are still executing the first set of commands.
Claims17
A method of selectively addressing one or more transponders in a set of transponders, the method comprising:
- selecting a first command, such that the first command is not executable by a first subset of transponders or is executable in a shorter time by the first subset of transponders than by a second subset of transponders in the set;
- transmitting the first command to the transponders;
- and
- transmitting a second command to the transponders at a predetermined time for execution by the first subset of transponders, the predetermined time selected such that the second command is received by the set of transponders while the second subset of transponders is still executing the first command.
Apparatus for selectively addressing one or more transponders in a set of transponders, the apparatus comprising:
- a controller;
- and
- a transmitter, optionally a transceiver;
- wherein the apparatus is configured to transmit a first command, the first command selected, based on statuses of the transponders, to be not executable by a first subset of transponders in the set or to be executable in a shorter time by the first subset of transponders than by a second subset of transponders in the set, and to transmit a second command to the transponders at a predetermined time for execution by the first subset of transponders, the predetermined time selected such that the second command is received by the set of transponders while the second subset of transponders are still executing the first command.
