Apparatus capable normally of presentation of time in hours and minutes and upon command of other functions, such as miles before service is required and days before service is required. The apparatus includes at least one logic integrated circuit for providing required frequency division of various inputs, a storage for accumulating information received from the integrated circuit and for retaining the information over a period of time even though power to the circuit is interrupted, a power supply and a display for displaying information on demand.

A system for automotive vehicles adapted both for providing automatically at least a display representing a time function in minutes and hours and upon manual activation a different display to advise the operator of said automotive vehicle of the state of a selected one of a plurality of other functions which periodically are changing, said system comprising: a. circuit means including 1. a source of a first input frequency, 2. first divider means connected to said source providing an output which is of a frequency comprising a division of said first input frequency, 3. second divider means having an output of a frequency comprising a further division of said first input frequency, 4. means connecting said first and second divider means whereby said output of said first divider means comprises the input of said second divider means, and 5. a time register also connected to said output of said first divider means, said time register being continuously updated during operation of said system; b. storage means comprising at least a first storage network, said first storage network connected to said second divider means thereby both to receive said output of said second divider means and store information so that said first storage network continually represents the then present condition of one of said plurality of other functions; c. a display adapted normally to display said time function and upon command to discontinue said normal display and to display said selected one of said plurality of other functions; d. means connecting each of said storage means and time register to said display, said connecting means including 1. control means included between said display and storage means for gating said selected one of said plurality of other functions to said display and isolating all other functions from said display; e. means for activating said control means; and f. power means for energizing each of said circuit means, storage means and display.
