Abstract
The duration of variations in the potential applied to a single electrical contact, when compared to a reference potential, are measured and employed to command either incrementing or decrementing of an address. The addresses are associated with a table of instructions and an addressed instruction, when read, will produce a discrete warning signal. A desired one of several light flash or audible patterns may be selected by step-wise scrolling through the table in response to manually varying the contact potential.
