Abstract
A vehicle glass assembly includes a glass pane of tempered glass, a frequency modulation (FM) antenna loop coupled to the glass pane and a first connector configured to provide a signal path to an FM radio tuner module. A second connector is coupled to the FM antenna loop to form an anti-theft loop in conjunction with the first connector. The first and second connectors are configured to provide signal paths to a security module.
Claims14
A vehicle system comprising:
- a vehicle glass assembly comprising:
- a glass pane of tempered glass;
- a frequency modulation (FM) antenna loop coupled to the glass pane and a first connector;
- and
- a second connector coupled to the FM antenna loop to form an anti-theft loop in conjunction with the first connector;
- a first signal path between the first connector and a vehicle electronics subsystem;
- a second signal path between the second connector and the vehicle electronics subsystem;
- and
- the vehicle electronics subsystem comprising a selection module configured to selectively electrically connect at least one of the first and second signal paths to an FM radio tuner module, and to selectively electrically connect the first and second signal paths to a security module when the first and second signal paths are not electrically connected to the FM radio tuner module.
6 more elements
A method comprising:
- determining, by a switch module of a vehicle electronics subsystem, that a radio mode is active based on one or more vehicle inputs;
- electrically connecting, by a selection module of the vehicle electronics subsystem, at least one of a first and second signal paths to a frequency modulation (FM) radio tuner module based on the radio mode being set active, wherein the first signal path is between the vehicle electronics subsystem and a first connector of an FM antenna loop coupled to a glass pane of tempered glass of a vehicle glass assembly, and the second signal path is between the vehicle electronics subsystem and a second connector of the FM antenna loop that forms an anti-theft loop in conjunction with the first connector;
- and
- electrically connecting, by the selection module of the vehicle electronics subsystem, the first and second signal paths to a security module based on the radio mode being set inactive such that the first and second signal paths are not electrically connected to the FM radio tuner module when the radio mode is set inactive.
