Abstract

The present invention is a method for locating an asset in a facility. An example of an asset is a vehicle and an example of a facility is a parking facility. When the user enters the facility with the asset, the user receives a base and code from a base/code booth. The code may be stored on a removable card. The user secures the asset by entering the code. While the user is away from the facility, the present invention monitors the base for movement detected by the motion sensor. When the user returns to the facility, a locator panel displays the location of the asset. The present invention determines the location of the asset by triangulation using the locators. The user then returns to the asset, deactivates the motion sensor, returns the base and code to a base/code booth, pays for the storage services, and exits the facility.

Claims

1. A system for locating a vehicle in a multi-level parking facility, the system comprising:

a card;

a base inside the vehicle and associated with the card, the base comprising;

a card reader for reading the card;

a motion sensor, wherein removing the card from the base activates the motion sensor, and wherein inserting the card into the base deactivates the motion sensor; and

a light;

a booth at the entrance of the multi-level parking facility for distributing the card and the base to a driver of the vehicle;

at least three locators on each level of the multi-level parking facility wherein said at least three locators are in communication with the base;

a locator panel in communication with the base and with said at least three locators, wherein responsive to the card being inserted into the locator panel, the locator panel triangulates the position of the base;

wherein the base transmits a disturbance signal to the locator panel upon movement of the vehicle while the motion sensor is activated;

wherein responsive to the locator panel receiving the disturbance signal, the locator panel notifies a security patrol; and

wherein responsive to the driver inserting the card into the locator panel, the locator panel displays the position of the vehicle and the light in the base illuminates to assist the driver in locating the vehicle.
