Abstract
An enforcement shutter for an electronic meter comprises an enforcement display element having a highly visible surface and adapted to be fixed to the meter housing, and a cable for coupling the enforcement display element to the computer processor for controlling the operation of the enforcement display element. The enforcement shutter includes a holder having a window, a transparent protective plate positioned on the inner surface of the holder, a back plate adapted to be fixed to the holder for mounting the holder to the meter housing. The enforcement display element, which is positioned to face the transparent plate with a display surface visible in the holder window, may be mounted in the holder or to a surface of the inner electronic meter. The enforcement display element may be a LCD. When activated by the electronic meter processor to indicate that parking time has expired, the LCD displays a substantially uniform color and may be made to flash. In a further embodiment, a LCD display for an electronic parking meter comprises a display surface adapted to be positioned so as to be visible to a user. One or more display characters having a number of character segments are positioned on the display surface. The segments are adapted to be coupled to the computer processor for displaying parking time. At least one filler segment is positioned to cover essentially the entire visible display surface not used by the display characters. The filler segment is adapted to be coupled to the computer processor for indicating that the parking time has expired.
