Abstract: A plug-in communication system, for implementation with a vehicle. The system in one aspect includes an onboard diagnostics port-expansion device, configured for mounting in the vehicle to, or adjacent, an onboard diagnostics port, and an onboard diagnostics port expansion connection line extending from the onboard diagnostics port-expansion device, the connection line being configured to connect the port-expansion device to one or more vehicle components. In another aspect, the system includes an inline remote-services terminal configured for wired connection inline, via a plurality of connection lines, to a remote-services module of the vehicle, a first connection line, of the plurality of connection lines, configured to connect to the inline remote-services terminal and to the remote-services module, and a second connection line, of the plurality of connection lines, configured to connect to the inline remote-services terminal and to the remote-services module.

Abstract: A vehicle antenna comprising: an antenna structure having an input impedance, ZA, equal to a sum of a resistance and an active impedance; a circuit element having high circuit element impedance at an operating frequency range of the antenna, wherein the circuit element is coupled in parallel with the input impedance.

Abstract: Where a knitted cover is intended to be subjected to a heat treatment to stabilize or otherwise process the fabric, it is useful to form a knitted-in portion (in an unobtrusive portion of the cover) using a suitably heat-sensitive yarn so that such heat treatment indicator portion undergoes a visual and tactile change to reveal that the cover has been so treated.

Abstract: A knitted fabric cover, especially for a vehicle seat having a vehicle air bag housed therein, in which the cover is adapted to provide minimal hindrance to inflation of the air bag by having at least one line of weakness knitted into the cover, in particular in a coursewise direction.
