More modern parking meters are generically called multispace meters (as opposed to single space meters) and control multiple spaces per block (typically 8-12) or lot (unlimited). While with these meters the parker may have to walk several car lengths to the meter, there are significant benefits in terms of customer service, performance and efficiency.Multispace meters incorporate more customer-friendly features such as on-screen instructions and acceptance of credit cards for payment-no longer do drivers have to have pockets full of coins on hand. They also have many performance benefits that keep them performing better. While they still may be prone to coin jams and other types of vandalism, most of these meters are wireless and can report problems immediately to maintenance staff, who can then fix the meters so that they are not out of service for very long.
Parking meters were invented by Carl C. Magee in 1932.

Perths first parking meters were installed in 1957.
Because of its photovoltaic and photoconductive properties, selenium is used in photocopying, photocells, light meters and solar cells. Its use as a photoconductor in plain-paper copiers once was a leading application but in the 1980s, the photoconductor application declined (although it was still a large end-use) as more and more copiers switched to the use of organic photoconductors. It was once widely used in selenium rectifiers.
Almost all of Puerto Rico's citys have parking meters in the downtown area.
Parking meters are used in many urban areas to restrict parking zones and to collect money for parking. Each city may have different rules and rates based off time of day and day of the week. Generally, money is deposited into the meter in accordance for the anticipated time the vehicle will remain in the parking spot. Money can be added as needed into the meter.

A CCD is a group of photocells. Photocells are cells that react to a broad range of light rays. CCD's convert light into an electric charge.
