A method of removing backing film from a sheet element is provided. The sheet element has a preimpregnated layer, and sheets of backing film are adhered to the top and bottom of the preimpregnated layer. The backing film has a different coefficient of thermal expansion than the preimpregnated layer, and a plane of the sheet element is defined by the peripheral edge. A shear strain is created between the backing films and the preimpregnated layer by cooling the sheet element. A fluid stream is directed at a portion of the peripheral edge, the fluid stream being directed in the plane of the sheet element. The fluid stream causes the backing films to separate from the top and bottom of the preimpregnated layer. A differential pressure is simultaneously applied to the backing films relative to the fluid stream to cause the backing films to be removed from the preimpregnated layer.

A Smart Parking Meter System makes it possible to track whether or not a vehicle occupies parking meter stalls and whether or not the time has expired. The system uses a wireless communication protocol which may be of the type known under the trade mark &ldquo;Bluetooth&rdquo; and provides the portability of embedded systems and the convenience of personal digital assistants with the powers of the C and Java programming languages. There are two main components to the Smart Parking Meter System, the handheld device, or the PDA, and the actual parking meters. Each device has the Smart Parking Meter System application installed in it, as well as the wireless modules, such as Bluetooth to use as a communication medium. The parking meters also have a motion sensor to detect any movement within it view range. The handheld device is able to extract all the parking states for each parking meter within a block or street depending on user configuration of system.
