Abstract
One or more inertially controlled switches may be coupled to a radio frequency identification (RFID) tag, so that the response of the RFID tag indicates the state of the switch(es). The RFID tag and the switch(es) may be coupled together in various ways so that the state of the switches affects the response of the RFID tag to an RFID reader.
Claims5
An apparatus, comprising:
- first and second radio frequency identification (RFID) tag circuits;
- a first inertially controlled switch (ICS) coupled to the first RFID tag circuit;
- a second ICS coupled to the second RFID tag circuit;
- and
- an antenna coupled to the first and second ICS;
- wherein the first and second ICS's are disposed such that only one of the first and second RFID tag circuits is to be operationally coupled to the antenna through the respective ICS at a time.
3 more elements
A method, comprising:
- performing an operation based on a response to a poll by a radio frequency identification (RFID) reader;
- wherein the response indicates a state of an inertially controlled switch (ICS) coupled to a passive RFID tag;
- wherein said performing comprises performing the operation if the response was received by the RFID reader within a designated time, and not performing the operation if the response was not received by the RFID reader within the designated time.
An article comprising
- a machine-readable medium that provides instructions, which when executed by a computing platform, cause said computing platform to perform operations comprising:
- performing an operation based on a response to a poll by a radio frequency identification (RFID) reader;
- wherein the response indicates a state of an inertially controlled switch (ICS) coupled to a passive RFID tag;
- wherein said performing comprises performing the operation if the response was received by the RFID reader within a designated time, and not performing the operation if the response was not received by the RFID reader within the designated time.
