Transmission module 220 as shown in FIG. 2 is a radio frequency (RF) transmitter.
Transmission module 220 receives GPS location information from location determination module 210 through location GPS data pathway 212. Transmission module 220 may be configured to transmit the GPS location only while transmitter 120 is located within car lot 130.
Transmission module 220 may transmit in the UHF bandwidth. In some embodiments, transmission module 220 does not transmit a cellular signal. In certain non-limiting embodiments of the present disclosure, transmission module 220 may transmit signals that conform to the JenNet or ZigBee protocol.
[0015] In certain embodiments, transmitter 120 may further include vehicle information module 230. In other embodiments (not shown), transmitter 120 does not include vehicle information module 230. Vehicle information module 230 may be adapted to communicate with one or more computer systems of the vehicle. Vehicle information module 230 may gather vehicle information from the vehicle and pass that information to transmission module 220 through vehicle information data pathway 222.
[0016] In some non-limiting embodiments, vehicle information module 230 is configured to meet OBD-II standards in terms of, for example, diagnostic connector and its pinout, electrical signaling protocols and messaging format. In certain embodiments of the present disclosure, vehicle information module 230 may receive power from the vehicle's battery through a power pin connector (not shown). Power pin connector may be configured in accordance with OBD-II standards. Vehicle information module 230 may gather information such as, but not limited to VIN, battery voltage, alternator voltage, fuel level, engine RPMs, vehicle speed, distance traveled since codes last cleared, run time since engine start and other parameters, such as those specified in the OBD-II standard. Vehicle information module 230 may be configured in accordance with OBD-II standards to plug into or be removed from a vehicle's OBD-II port. When so configured, transmitter 120 may be removable from the vehicle, for instance, when the vehicle is purchased, and reused on a different vehicle.

The transmission module processor of transmission module 220 may include in the processor or memory associated with the transmission module processor code instructions to transmit information to receiver station 110 continuously, at pre-determined times, or may use the information obtained from location determination module 210 or vehicle information module 230 to determine when to transmit information to receiver station 110. The code instructions may be stored on a non-transitory, tangible computer readable storage medium. As an example, when vehicle information module 230 communicates to transmission module 220 that the measured voltage is such that the engine of the vehicle is running, transmission module may transmit vehicle location more frequently than if the measured voltage is such that the engine of the vehicle is not running.
As another example, if the engine of the vehicle is running, transmission module 220 may transmit location information every two seconds, every five seconds, or every 10 seconds. If the engine of the vehicle is not running, transmission module 220 may transmit location information once every two hours, once every hour, or once every 30 minutes, for example.
Similarly, the duration of the transmission of vehicle information by transmission module 220 may be for a set time or based on vehicle information.
[0019] In some embodiments, transmitter 120 may be limited in range in that the signal of transmitter 120 may be received less than a mile, less than 2500 feet or less than 1500 feet from transmitter 120.
[0020] FIG. 3 is a schematic of receiver 110 in accordance with certain embodiments of the present disclosure. Receiver 110 includes RF antenna 330. RF antenna 330 receives the RF
signal from transmitter 120. RF antenna 330 provides data received from transmitter 120 through receiver data path 322 to receiver processor 320. Receiver processor 320 stores, manipulates, and/or prepares data received through receiver data path 322 for display and/or query from a user. As recognized by one of ordinary skill in the art with the benefit of this disclosure, receiver processor 320 may be any electronic equipment capable of storing, manipulating, and/or preparing data received through receiver data path 322.
In certain non-limiting embodiments, receiver processor 320 may be a laptop or desktop computer, a handheld device such as a PDA or smartphone, or tablet.
