Abstract
A system, device, and method are disclosed for reducing or eliminating interference between proximate electronic devices. The system, device, and method rely on a switch communicatively disposed between a signal origination device and an antenna. Further, the switch is connected to an electronic device and is operable to receive a signal from the electronic device corresponding to whether the electronic device is in an activated or de-activated state. Additionally, when the electronic device is in an activated state, the switch is operable to open, preventing communication between the signal origination device and the antenna.
Claims20
A system comprising:
- a signal origination device operable to communicate a first signal when in a presence of a second signal, the first signal within a first frequency range and the second signal within a second frequency range;
- a switch connected to the signal origination device;
- an antenna connected to the switch, the antenna operable to transmit the first signal;
- and
- an electronic device operable between activated and de-activated states, the electronic device connected to the switch;
- wherein, the switch is operable to:
- open when the electronic device is in an activated state, preventing communication between the signal origination device and the antenna, and
- close when the electronic device is in a de-activated state, enabling communication between the signal origination device and the antenna.
A device comprising:
- a passive radio frequency identification tag operable to communicate a first signal in the presence of a second signal;
- an antenna communicatively connected to the passive radio frequency identification tag and operable to transmit the first signal;
- and
- a switch communicatively disposed between the passive radio frequency identification tag and the antenna, the switch operable to:
- receive a third signal from an electronic device, the third signal corresponding to an activated state of the electronic device, and
- based on the received third signal, disable communication between the passive radio frequency identification tag and the antenna.
A method comprising:
- receiving, a first signal from an electronic device, the first signal corresponding to the electronic device being in an activated state;
- and
- opening a switch based, at least in part, on receiving the first signal, wherein opening the switch is operable prevent communication between a passive RFID tag and an antenna.
