Abstract
Abstract A system for preventing theft of cargo from a cargo area of a truck is disclosed. The system includes a lock for locking shut a door to the cargo area of the truck when the lock is engaged. The lock allows the door to the cargo area to be opened when the lock is disengaged. A receiver receives a signal from a remote location. The lock is controlled in response to the signal received from the remote location such that the lock is disengaged when the signal received from the remote location is indicative of predetermined information.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
282 words
A system for preventing theft of cargo from a cargo area of a truck, the system comprising: a lock for locking shut a door to the cargo area when the lock is engaged, the lock allowing the door to the cargo area to be opened when the lock is disengaged; means for receiving a signal transmitted from a remote location; means for controlling the lock in response to the signal received from the remote location such that the lock is disengaged when the signal received from the remote location is indicative of predetermined information, the means for controlling the lock being coupled to the means for receiving a signal from the remote location and being coupled to the lock; wherein the means for receiving the signal from a remote location includes a first satellite transceiver for receiving a signal from a first satellite; wherein the first Satellite is a communications satellite and wherein the signal received from the first satellite corresponds to a signal originating from a control center, the predetermined information including a code that allows the means for controlling the lock to disengage the lock; and means for receiving a signal from a second satellite, the second satellite being a GPS satellite, a position of the truck being determined as a function of the signal received from the second satellite, wherein the means for controlling the lock in response to the signal received from the first satellite further controls the lock such that the lock is disengaged when both the signal received from the first satellite is indicative of predetermined information and the determined position of the truck is substantially the same as a predetermined desired position of the truck.
Claim 2
Independent Claim
282 words
A system for preventing theft of cargo from a cargo area of a truck, the system comprising: a lock for locking shut a door to the cargo area when the lock is engaged, the lock allowing the door to the cargo area to be opened when the lock is disengaged; means for receiving a signal transmitted from a remote location; means for controlling the lock in response to the signal received from the remote location such that the lock is disengaged when the signal received from the remote location is indicative of predetermined information, the means for controlling the lock being coupled to the means for receiving a signal from the remote location and being coupled to the lock; wherein the means for receiving the signal from a remote location includes a first satellite transceiver for receiving a signal from a first satellite; wherein the first Satellite is a communications satellite and wherein the signal received from the first satellite corresponds to a signal originating from a control center, the predetermined information including a code that allows the means for controlling the lock to disengage the lock; and means for receiving a signal from a second satellite, the second satellite being a GPS satellite, a position of the truck being determined as a function of the signal received from the second satellite, wherein the means for controlling the lock in response to the signal received from the first satellite further controls the lock such that the lock is disengaged when both the signal received from the first satellite is indicative of predetermined information and the determined position of the truck is substantially the same as a predetermined desired position of the truck.
Claim 3
Dependent Claim
43 words
The system of claim 1, wherein the first satellite is a GPS satellite and wherein the means for receiving a signal from the first satellite includes a GPS receiver, the predetermined information being indicative of the truck being positioned at a predetermined location.
Claim 4
Dependent Claim
