An asymmetrical virtual ground single transistor floating gate memory cell has a floating gate that overlies a channel region in a p-well, the channel region lying between a heavily doped n+ drain region and a lightly doped n\u2212 source region. The system includes a spray delivery device configured to release a pressurized substance in response to an activation signal, an activation device configured to transmit an activation signal to the spray delivery device, and a power supply, configured to provide power to at least one of the activation devices and the spray delivery devices. The data for anticipating certain modes of vehicle operation along the anticipated route of travel and data geographically tracking vehicle travel along the projected route are interactively used to control timing of performance of the maintenance function as the vehicle travels along the projected route. The stationary pad is disposed inside the loop of the belt.
