Abstract

A tilt indicator includes a housing having a tilt detection assembly, switch circuitry, and a radio-frequency identification (RFID) module coupled to the switch circuitry. Responsive to the tilt detection assembly being subjected to a tilt event exceeding a threshold, the switch circuitry causes a change in a value output by the RFID module when activated.

Claims (41)

1. A tilt indicator, comprising:

a housing having a tilt detection assembly;

switch circuitry; and

a radio-frequency identification (RFID) module coupled to the switch circuitry and configured to output a first value in an unactivated state of the tilt indicator and a second value in an activated state of the tilt indicator; and

wherein responsive to the tilt detection assembly being subjected to a tilt event exceeding a threshold, the switch circuitry causes the second value to be output by the RFID module when energized.

2. The tilt indicator of claim 1 , wherein the tilt detection assembly includes a receptacle containing a mass member, and wherein response to the tilt detection assembly being subjected to the tilt event exceeding the threshold, the mass member exits the receptacle to thereby cause the second value to be output by the RFID module.

3. The tilt indicator of claim 1 , wherein the switch circuitry includes a plurality of conductive surfaces formed on a receptacle, and wherein the receptacle is configured to support a conductive mass member therein, and wherein the conductive mass member is configured to contact the plurality of conductive surfaces in the unactivated state of the tilt indicator.

4. The tilt indicator of claim 1 , wherein the switch circuitry is configured to be in a state of either a closed circuit or an open circuit, and responsive to the tilt detection assembly being subjected to the tilt event exceeding the threshold, a change to the state occurs.

5. The tilt indicator of claim 1 , wherein the RFID module includes a passive RFID module.

6. The tilt indicator of claim 1 , wherein the switch circuitry includes:

first and second conductive surfaces formed on a receptacle, and wherein the receptacle is configured to support a conductive mass member therein; and

first and second conductors extending through a support member of the housing and electrically connected to the respective first and second conductive surfaces; and

wherein the RFID module is coupled to the first and second conductors.

7. The tilt indicator of claim 6 , wherein the conductive mass member is configured to conductively connect the first conductive surface with the second conductive surface in the unactivated state of the tilt indicator.

8. A tilt indicator, comprising:

a housing having a tilt detection assembly;

a communication module; and

switch circuitry conductively connected to a mass member of the tilt detection assembly when the tilt indicator is in an upright position, and wherein responsive to the tilt indicator being subjected to a tilt event exceeding a threshold, the mass member moves from a first position to a second position and disconnects from the switch circuitry, and wherein the communication module is configured to indicate an activated state of the tilt indicator in response to the disconnection, and wherein the tilt detection assembly is configured to prevent the mass member from returning to the first position in response to the tilt indicator returning to the upright position.

9. The tilt indicator of claim 8 , wherein the communication module includes a passive radio-frequency identification (RFID) module.

10. The tilt indicator of claim 8 , wherein the mass member comprises a conductive mass member.

11. The tilt indicator of claim 8 , wherein the tilt detection assembly includes a receptacle configured to support the mass member in an unactivated state of the tilt detection assembly, and wherein responsive to the tilt indicator being subjected to the tilt event exceeding the threshold, the mass member exits the receptacle and disconnects from the switch circuitry.

12. The tilt indicator of claim 8 , wherein the switch circuitry is configured to change from a closed circuit to an open circuit in response to the tilt indicator being subjected to the tilt event exceeding the threshold.

13. A tilt indicator, comprising:

a housing having a tilt detection assembly;

an arming element configured to maintain the tilt detection assembly in an unarmed state;

switch circuitry; and

a radio-frequency identification (RFID) module coupled to the switch circuitry and configured to output a first value in an unactivated state of the tilt indicator and a second value in an activated state of the tilt indicator; and

wherein removal of the arming element from the tilt indicator places the tilt detection assembly in an armed state, and wherein responsive to the tilt detection assembly being subjected to a tilt event exceeding a threshold after being in the armed state, the switch circuitry causes a change from the first value being output by the RFID module when energized to the second value being output by the RFID module when energized.

14. The tilt indicator of claim 13 , wherein the switch circuitry includes a plurality of spaced apart conductive elements, and wherein the tilt detection assembly includes a conductive mass member configured to conductively connect the conductive elements in the unactivated state of the tilt detection assembly.

15. The tilt indicator of claim 14 , wherein responsive to the tilt detection assembly being subjected to the tilt event exceeding the threshold, the mass member moves to a position to conductively disconnect the conductive elements from each other.

16. The tilt indicator of claim 13 , wherein the tilt detection assembly includes:

a receptacle formed by a plurality of spaced apart side elements; and

a mass member disposed within the receptacle in the unactivated state of the tilt detection assembly; and

wherein the switch circuitry includes a conductive portion formed on each of the side elements, and wherein the mass member is configured to conductively connect the respective portions, and wherein responsive to the tilt detection assembly being subjected to the tilt exceeding the threshold, the mass member leaves the receptacle and conductively disconnects the portions from each other.

17. The tilt indicator of claim 16 , wherein the switch circuitry includes a proximity sensor.

18. The tilt indicator of claim 13 , wherein the RFID module comprises a passive RFID module.

19. The tilt indicator of claim 13 , wherein the switch circuitry is configured to be in a state of either a closed circuit or an open circuit, and responsive to the tilt detection assembly being subjected to the tilt event exceeding the threshold, a change to the state occurs.

20. The tilt indicator of claim 13 , wherein the switch circuitry includes:

first and second conductive surfaces formed on a receptacle, and wherein the receptacle is configured to support a conductive mass member therein; and

first and second conductors extending through a support member of the housing and electrically connected to the respective first and second conductive surfaces; and

wherein the RFID module is coupled to the first and second conductors.
