Patent DE-3936543-A1 (DE)
Inventor: KUNTZ WALTER PROF
IPC: G07C1/00
Filed: 1989-11-02
Abstract: An electrical expiry indicator with a selectable starting time and defined expiry time consists of a device the state of which varies with time and which emits a display signal when an expiry time is reached. The expiry time can be influenced by at least one given physical quantity, and therefore does not depend solely on the elapse of a certain time-interval. The time-dependent device is constructed as a clock-controlled counter (6) with adjustable expiry time, the clock frequency of which can be controlled in function of the physical quantity.
