Abstract: A vehicle sticker for monitoring a time-period associated with a motor vehicle, comprises an electronic timer, first and second indicator devices, and some mechanism for affixing the sticker to the vehicle. The timer is configured to time the time-period associated with the vehicle and to generate an "impending expiration" signal and an "expiration" signal. The first indicator device is coupled to the timer, and is configured to indicate an "impending expiration" or a "renewal" warning in response to the impending expiration signal. The second indicator device is also coupled to the timer, and is configured to indicate the expiration of the time-period in response to the expiration signal. The affixing mechanism must hold the sticker on the vehicle, in such a position that the impending expiration indication is directed to someone inside the vehicle and the expiration indication is directed to someone outside the vehicle.

Abstract: An electronic timing label for indicating the expiration of a time period associated with a particular article. The label comprises a pulse generator and a binary counter. The pulse generator is configured to generate a series of pulses at a predetermined pulse rate, and the counter is configured to count from an initial count number in response to the series of pulses and to generate an expiration signal upon reaching a final count number. The number of counts between the initial and final count numbers, and the pulse rate, are chosen to establish a counting time for the counter which corresponds to the time period associated with the article. The label also comprises a display for indicating the expiration of the time period, a programming port for directing programming pulses to the counter, and some mechanism for affixing the label to an application surface associated with the article.
