  • Programmable electronic time lock
    Patent number: 5594430
    Abstract: A programmable time lock includes a microprocessor, which senses the angular position of a key shaft via a sensor/encoder. The microprocessor includes ROM and RAM memory circuits, a timer, and a clock, and it can activate a stepper motor to control the position of a detent pin. The microprocessor is also connected to a display, which has fields for hours, minutes and seconds, as well as for the days of the week, for a cursor for each day, and for a low-power indicator. System time, as well as opening times for the lock may be set and changed simply by turning the key according to predefined routines. A method for operating the lock includes sets of steps for each of several routines: setting real time, setting opening times for each selected day of the week, and specialty routines including adding an intermediate opening time, cancelling the opening time for selected days, adjusting the system time, for example to change to or from daylight savings time, and verifying the version of the time lock in use.
