Vehicle location system
First Claim
1. A system for determining a location of a selected vehicle from which an alarm signal is generated:
- a fixed array of a plurality of individual wireless signal detecting means, each of said individual wireless signal detecting means for receiving an input alarm signal having a strength which is a function of the distance between the position of the selected vehicle generating said alarm signal and the position of each of said individual one of said plurality of wireless signal detecting means;
each of said individual wireless signal detecting means of said array including a wireless signal generating means for transmitting an output signal which is a function of the strength of said input alarm signal;
a main wireless signal detecting means for receiving an output signal from each of said individual wireless signal generating means; and
a control monitoring means, coupled to said main wireless signal detecting means, for receiving output signal there from, each of said output signals which is a function of the strength of said received input alarm signal, for determining the approximate location of said selected vehicle from which an alarm signal is generated.

Abstract
A system for determining a location of a selected vehicle from which an alarm signal is generated which includes a fixed array of cellular sites each site having a wireless signal detecting and generating units each of which is capable of receiving an input alarm signal having a signal strength which is a function of the distance between the position of the vehicle generating the alarm signal and the position of each of the wireless signal detecting units. Each unit also is capable of transmitting an output signal which is a function of the strength of the input alarm signal. The system also includes a main wireless signal detecting apparatus for receiving an output signal from each of the wireless signal detecting and generating units and a control monitoring unit which is coupled to the main woreless signal detecting apparatus, for receiving output signals there from, each of the output signals being a function of the strength of the received input alarm signal, for determining the approximate location of the selected vehicle from which the alarm signal is generated.

20. A system for determining a location of at least one selected vehicle from which a location signal such as an alarm or chase signal is generated:
-
a fixed array of a plurality of individual wireless signal detecting means, each of said individual wireless signal detecting means for receiving an input location signal having a strength which is a function of the distance between the position of the selected vehicle generating said location signal and the position of each of said individual one of said plurality of wireless signal detecting means; each of said individual wireless signal detecting means of said array including a wireless signal generating means for transmitting an output signal which is a function of the strength of said input location signal; a main wireless signal detecting means for receiving an output signal from each of said individual wireless signal generating means; and a control monitoring means, coupled to said main wireless signal detecting means, for receiving output signal therefrom, each of said output signals which is a function of the strength of said received input location signal, for calculating the approximate location of said selected vehicle from which a location signal is generated and for continuously recalculating the approximate location of said selected vehicle as its location changes.
