A cigarette lighter adapter (CLA) is disclosed comprising a body and a barrel portion extending therefrom, said barrel portion including a first and second contacts respectively connectable within a vehicle cigarette lighter to he powered therefrom, said CLA bering additionally provided with at least one primary electronic circuit within the body thereof, connected directly or indirectly to said contacts, and an output to which a power signal is capable of being delivered. The CLA is characterized in that it includes an antenna component in electrical communication with said primary electronic circuit, the latter delivering at least one of the antenna signal, a electronically processed version thereof, or data derived from the electronic processing thereof, to said output in conjunction with said power signal, the source of which is derived from said contacts or from an alternative power source provided within the body of said CLA, such as an on-baord rechargeable battery, said power signal source further providing power to said primary electronic circuit to enable operation thereof. Further features include the provision of one or more secondary electronic circuits within the CLA to provide power management, regulation, control, switching, and/or battery re-charging functions, and the segregation of the primary and secondary electric circuits so as to ensure effective heat dissipation. Most preferably, the CLA is provided with vents adjacent which at least one of the secondary electronic circuits is provided. In an alternative aspect, the invention provides a CLA with power circuitry, a wireless modem, an antenna, and a subscriber identity module (SIM), together with a further wireless transceiver by means of which signals received by the antenna and processed by the modem can be wirelessly communicated to a remote device. |
