Abstract
A temperature indicator includes a housing having a temperature detection assembly, switch circuitry, and a radio-frequency identification (RFID) module coupled to the switch circuitry. Responsive to the temperature detection assembly being subjected to a temperature exceeding a threshold, the switch circuitry causes a change in a value output by the RFID module when activated.
Claims20
A temperature indicator, comprising:
- a housing having a temperature detection assembly;
- switch circuitry;
- and
- a radio-frequency identification (RFID) module coupled to the switch circuitry;
- and
- wherein responsive to the temperature detection assembly being subjected to a temperature exceeding a threshold, the switch circuitry causes a change in a value output by the RFID module when activated.
3 more elements
A temperature indicator, comprising:
- a housing having a support member containing a non-conductive malleable substance;
- a communication module;
- and
- switch circuitry including a switch element having at least a portion thereof disposed within the malleable substance and spaced apart from a conductive element, and wherein responsive to the temperature indicator being subjected to a temperature exceeding a threshold, the portion moves within the malleable substance and into contact with the conductive element, and wherein the communication module is configured to indicate an activated state of the temperature indicator in response to the portion contacting the conductive element.
1 more element
A temperature indicator, comprising:
- a housing having a temperature detection assembly;
- an arming element configured to maintain the temperature detection assembly in an unarmed state;
- switch circuitry;
- and
- a radio-frequency identification (RFID) module coupled to the switch circuitry;
- and
- wherein removal of the arming element from the temperature indicator places the temperature detection assembly in an armed state, and where responsive to the temperature detection assembly being subjected to a temperature exceeding a threshold after being in the armed state, the switch circuitry causes a change in a value output by the RFID module when activated.
