Abstract
A wireless transmission tag (100) has a memory (110) coupled to an antenna (130) via control circuitry (120). The memory (110) typically stores data to be transmitted by the wireless transmission tag (100). The control circuitry (120), which may comprise a first circuit portion (122) and a second circuit portion (124), is powered by a power source (140). The power source (140) is coupled to a sensor (150), and is arranged to activate the power supply to at least a part of the control circuitry (120) upon the detection of an external stimulus by the sensor (150). This way, a wireless transmission tag (100) is provided that only starts transmitting data when activated by a predefined stimulus.
Claims7
A wireless transmission tag having:
- a memory;
- control circuitry coupled to the memory;
- an antenna coupled to the control circuitry;
- and
- a power source for powering the control circuitry,
- the power source being coupled to a sensor for activating a power supply from the power source to at least a part of the control circuitry responsive to an external stimulus.
A product tagged with a wireless transmission tag having a memory, control circuitry coupled to the memory, an antenna coupled to the control circuitry, and a power source for powering the control circuitry, the power source being coupled to a sensor for activating a power supply from the power source to at least a part of the control circuitry responsive to an external stimulus, the product comprising means for triggering the external stimulus.
A communication system comprising:
- a product tagged with a wireless transmission tag having:
- a memory;
- control circuitry coupled to the memory;
- an antenna coupled to the control circuitry;
- and
- a power sources for powering the control circuitry;
- the power source being coupled to a sensor for activating a power supply from the power source to at least a part of the control circuitry responsive to an external stimulus;
- and
- an electronic device comprising a processing unit and a receiver coupled to the processing unit, the processing unit being arranged to perform an operation relating to the external stimulus responsive to the reception by the receiver of data being transmitted by the wireless tag upon detection of the external stimulus.
A method of controlling an electronic device in a communication system comprising the electronic device and a wireless transmission tag,
- the method comprising the steps of:
- detecting an external stimulus by a sensor coupled to the wireless transmission tag;
- activating a data transmission from the wireless transmission tag in response to the detection of the stimulus;
- receiving the data transmission by the electronic device;
- and
- initiating an operation of the electronic device relating to the external stimulus in response to the reception of the data transmission.
