Device and method to prevent damage to objects mounted on top of automobiles

A protection system comprising:

• an assembly having a first transmitter, a switch, and a first power source, the assembly being mountable on a vehicle, wherein when the switch is activated, the first transmitter transmits a signal;
• and
• a first box having a receiver, a second transmitter, a sensor, a microprocessor, a second power source, and an output means, the first box being mounted in or on the vehicle, wherein the sensor detects reflections of pulses emitted by the second transmitter, wherein the microprocessor evaluates the reflections to determine the presence of a rigid object in the field of view that has a low clearance height for motor vehicle traffic, and wherein when the receiver receives a signal from the assembly and the microprocessor detects the presence of the rigid object, an output is created.

A protection system comprising:

• an assembly having a transmitter, a switch, and a first power source, the assembly being mountable on a vehicle wherein when the switch is activated, the transmitter transmits a signal;
• and
• a first box having a receiver, a global positioning system receiver, an output means, a second power source, and a memory means, the first box being mountable in or on the vehicle, wherein the memory means contains coordinates for one or more geographic locations, and wherein when the receiver receives a signal from the assembly and the global positioning system receiver detects that it is at a location near to one of the stored coordinates, an output is created.

A protection system comprising:

• a first box having a first transmitter, a second transmitter, a first sensor, a second sensor, a microprocessor, and a first power source, the first box being mountable on a vehicle, wherein the first sensor detects the presence of one or more additional objects mounted on the vehicle, and wherein the second sensor detects reflections of pulses emitted by the second transmitter and the microprocessor evaluates the reflections from the second transmitter to determine the presence of a rigid object in the field of view that has a low clearance height for motor vehicle traffic, and wherein when the microprocessor detects the one or more additional objects mounted on the vehicle and the rigid object, the first transmitter transmits a signal;
• and
• a second box having a receiver, an output means, and a second power source, the second box being mountable in or on the vehicle, wherein when the receiver receives the signal from the first box, an output is created.

A protection system comprising:

• an assembly having a first transmitter, a switch, and a first power source, the assembly being mountable on a vehicle, wherein when the switch is activated, the first transmitter transmits a first signal;
• a first box having a first receiver, a second transmitter, a third transmitter, a sensor, a microprocessor, and a second power source, the first box being mounted on the outside the vehicle, wherein the sensor detects reflections of pulses emitted by the second transmitter, wherein the microprocessor evaluates the reflections to determine the presence of a rigid object in the field of view that has a low clearance height for motor vehicle traffic, and wherein when the microprocessor detects the presence of the rigid object, the third transmitter transmits a second signal;
• a second box, containing a second receiver, an output means, and a third power source, the second box being mountable in or on the vehicle, wherein when the second receiver receives the first signal from the assembly and the second signal from the first box, an output is created.

A protection system comprising:

• a first assembly having a transmitter and a first power source mounted on or near a rigid object;
• and
• a second assembly having a receiver, an output means, and a second power source, the second assembly being mounted on a moveable object, wherein when the receiver receives a signal from the assembly, an output is created.
