ABSTRACT:
An electronic data storage and retrieval system, particularly embodied in an electronic watch instrument interrogated and controlled by a timed sequence of voltage pulses generated by the user's actuation of a switch or by his tapping or otherwise impacting an electroacoustic transducer such as a small earphone. For audible readout the instrument circuitry, when interrogated, drives the transducer to produce a coded sequence of tones easily learned by the user. The instrument may include an optical readout capability. Register means are provided for auxiliary data and for an alarm capability, and suitably coded user-produced voltage pulses serve to set a desired time in the alarm register, to arm or disarm the alarm, to read out the alarm time, to reset the basic time of the instrument, and to arm or disarm a periodic time readout.
