Abstract
According to one aspect of the present disclosure, a device and technique for impact detection includes a housing and switch circuitry having an omega-shaped switch element. A passive radio-frequency identification (RFID) module is coupled to the switch circuitry and is configured to detect a state of a circuit condition of the switch circuitry. A mass member is movable within the housing from a first position to a second position in response to receipt by the housing of an acceleration event. Movement of the mass member to the second position causes the mass member to move the switch element to change the state of the circuit condition of the switch circuitry.
Claims20
An impact indicator, comprising:
- a housing;
- switch circuitry having an omega-shaped switch element;
- a passive radio-frequency identification (RFID) module coupled to the switch circuitry, the RFID module configured to detect a state of a circuit condition of the switch circuitry;
- and
- a mass member movable within the housing from a first position to a second position in response to receipt by the housing of an acceleration event, wherein movement of the mass member to the second position causes the mass member to move the switch element to change the state of the circuit condition of the switch circuitry.
An impact indicator, comprising:
- a housing;
- switch circuitry having an omega-shaped switch element coupled to a plurality of spaced apart conductive contacts;
- a passive radio-frequency identification (RFID) module coupled to the switch circuitry, the RFID module configured to detect a state of a circuit condition of the switch circuitry;
- and
- a mass member movable within the housing in response to receipt by the housing of an acceleration event, wherein movement of the mass member causes the switch element to disengage from the contacts to change the state of the circuit condition of the switch circuitry.
An impact indicator, comprising:
- a housing;
- switch circuitry having an omega-shaped switch element and a plurality of spaced apart conductive contacts, wherein each leg of the switch element is coupled to a respective contact;
- a passive radio-frequency identification (RFID) module coupled to the switch circuitry, the RFID module configured to detect a state of a circuit condition of the switch circuitry and transmit a value indicative of the state;
- and
- a mass member movable within the housing in response to receipt by the housing of an acceleration event, wherein movement of the mass member causes the switch element to disengage from the contacts to change the state of the circuit condition of the switch circuitry.
