Abstract: A system (10) for proportionately spacing a plurality of characters is disclosed. The system includes a memory for storing a character font defining a group of characters which may be individually selected. Each selectable character contains at least one matrix of pixels with each matrix containing a plurality of rows of pixels with each row having pixels extending in a direction of reading of the pixels from the memory. Visible pixels in the at least one matrix of each selectable character define a visible shape which is stored in the memory as a first binary value. Background pixels in the at least one matrix of each selectable character, which are a remainder of a total number of pixels in the at least one matrix of each selectable character, are stored in the memory as a second binary value.

Abstract: A fuel dispenser for installation in a service station equipped with a dispenser control console includes a housing, a pump to pump fuel through the housing, a fuel flow meter in the housing, a switch actuable to indicate fuel is to be pumped through the housing, a display on the housing to display the amount of fuel pumped through the housing, and a dispenser control. The dispenser control includes a plurality of microcontroller nodes and a communications bus connecting the microcontroller nodes. A first node is associated with the switch, pump and fuel flow meter, a second node is associated with the display, and a third node is associated with a data link to the dispenser control console.

Abstract: An apparatus for displaying video information includes a video display screen, a screen buffer, a frame buffer, and a video image data assembly module. The module assembles data from linked lists of screen objects, segment objects and field objects which identify images stored in the frame buffer into video image data to store in the screen buffer to be displayed on said screen. Data elements in the lists are linked in a hierarchical arrangement of most-significant to least-significant data elements, with significance denoted by the usual size of the data element as displayed on said screen, so that selecting data from an upper one of the members of a hierarchical list thereby selects data from a lower member by virtue of the linking of the lower member to the upper member.
