Pocket calculator for the forecasting of temporal cycles
First Claim
Patent Images
1. A pocket calculator for the forecasting of temporal cycles, comprising:
- an electrical power supply, input means for inputting data corresponding to dates and calculation instructions to said calculator, electronic calculation means including means for receiving said data from said input means and means for carrying out temporal cycle forecasting calculations in response to the instruction data and for producing output signals corresponding to the results of said calculations, display means controlled by said output signals, an electromechanical memory for retaining variable data and including a plurality of electromechanical memory units, each electromechanical memory unit comprising a bistable electromechanical miniature relay having at least one control solenoid and means for maintaining the mechanical position of said relay even in the absence of power from said electrical power supply, so as to retain the variable data even if the electrical power supply is cut off, each said relay including a plurality of relay contacts for reading the position of the relay and hence the variable data stored therein, said electromechanical memory further comprising writing means selectively actuatable for transmitting a writing pulse to each said relay and reading circuit means selectively actuatable for reading the position of each relay at the respective relay contacts thereof, the actuation of said reading means and said writing means being controlled by said electronic calculation means, and wherein said electromechanical memory is coupled in circuit to be read only by the electronic calculation means and for having date information written thereinto by successive introduction of data by manual actuating of the input means and wherein said calculator further includes a write control key and a safety key, said electronic calculation means being responsive to said write control key and said safety key for actuating said writing means only when said write control key and said safety key are simultaneously actuated.

Abstract
The memory (80) is intended to be read or modified by an electronic logical system of a pocket calculator. It comprises a plurality of bistable electromechanical flip-flop circuits (82). Each flip-flop circuit (82) comprises an input for setting at 1 (S) and an input for setting a zero (R) and an output (78). The inputs are connected individually to a multiplexor (702) controlled by a control circuit (701). The control circuit (701) is connected in two directions with a central processor via a bus (51). The control circuit (701) manages readings and writings to the memory (80).
The memory is intended to memorize data which have to be retained in the calculator in a reliable and convenient way, even if the supply is cut off. The calculator is, for example, intended to make calculations concerning the application of the Ogino method, the data to be memorized being the durations of previous cycles and the date of the last period.
