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.
Claims20
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.

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.

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.
