Abstract
A latch assembly may comprise: a housing; a pawl assembly coupled to the housing, the pawl assembly configured to transition from an un-restrained state to an restrained state; and a latch state detection system comprising a transducer and a communications module, the transducer configured to convert mechanical energy from the pawl assembly reaching the restrained state to an electrical energy configured to power the communications module.
Claims19
A latch assembly, comprising:
- a housing;
- a pawl assembly coupled to the housing, the pawl assembly configured to transition from an un-restrained state to a restrained state;
- and
- a latch state detection system comprising a transducer and a communications module, the transducer configured to convert mechanical energy from the pawl assembly reaching the restrained state to an electrical energy configured to power the communications module, wherein in response to receiving the electrical energy, the communications module is powered and configured to transmit a signal to a control unit of a cargo handling system.
1 more element
A cargo handling system, comprising:
- a control unit comprising one of a first transceiver or a receiver;
- a latch state detection system comprising:
- a transducer configured to convert mechanical energy to electrical energy;
- and
- a communications module in electrical communication with the transducer, the communications module including one of a transmitter or a second transceiver, the transmitter or the second transceiver configured to be powered by the transducer in response to a latch assembly reaching a fully restrained state, the transmitter or the second transceiver configured to send a wireless signal to the first transceiver or the receiver in response to being powered by the transducer wherein in response to receiving the electrical energy, the communications module is powered and configured to transmit the wireless signal to the first transceiver or the receiver.
2 more elements
A cargo handling system, comprising:
- a control system comprising a main controller and a receiver;
- a plurality of latch assemblies configured to be disposed throughout a cargo deck, each latch assembly in the plurality of latch assemblies comprising a latch state detection system, the latch state detection system including a transmitter, the transmitter configured to transmit a unique identifier to the receiver of the control system in response to a respective latch reaching a fully restrained state wherein:
- each of the plurality of latch assemblies comprises a transducer configured to convert mechanical energy to electrical energy, and
- in response to receiving the electrical energy, the transmitter is powered and configured to transmit a signal to a control unit.
