Electronic diary

An electronic display apparatus comprising in combination:

• electronic diary means including means for generating real time of day and date signals and means for storing for predetermined releases thereof message time of day and date signals and associated daily schedule and message events data signals, electronic calculating means for calculating composite and resultant numeric signals representative of certain selected calculative operations determined by input preselected numeric values and arithmetic operations, input selector means including Keyboard actuable Keys, first ones of which are connected to said electronic diary means and second ones of which are connected to said electronic calculating means, selective actuation of said first ones of said Keys providing first input signals comprising predetermined message time of day and date signals and preselected associated daily schedule and message events data signals and selective actuation of said second ones of said Keys providing second input signals comprising said input preselected numeric values and arithmetic operations, time comparison logic means connected to receive both real time of day and date signals and message time of day and date signals, said comparison means comparing the same and providing an equal comparison output signal responsive to equal comparison thereof, respectively, first display control means connected to said time comparison means to receive said equal comparison output signals and to said electronic diary means to receive said real time of day and date signals and said message time of day and date signals and associated daily schedule and message events data signals, said first display control means providing first displayable output signals representative of said real time of day and date signals when said real time of day and date signals and said message time of day and date signals are unequal, respectively, and providing second displayable output signals representative of said message time of day and date signals and said daily schedule and message events data signals when said equal comparison output signals are received, respectively, second display control means connected to said electronic calculating means and providing third displayable output signals representative of said composite and resultant numeric signals, selector gating means connected to receive as inputs thereto said first, second and third displayable output signals from said first and second display control means and gating the release of a selected one of said first, second and third displayable output signals as a resultant displayable output signal, and means for visually displaying said resultant displayable output signal.

An electronic diary circuit comprising in combination:

• clock-calendar means including first counter means counting time units in seconds, minutes, hours, days, months, and dates for comprising real time of day and date signals and further including first memory means having first stored time data signals representative of selected combinations of said real time of day and date signals, said first memory means providing selected ones of said first stored time data signals as first output signals therefrom in response to the input of said real time of day and date signals from said first counter means, keyboard selector means for selecting input registration signals, first ones thereof being representative of message time of day and date signals and second ones thereof being representative of daily schedule and message events data signals, visual display means for visually displaying selected output signals, message control means selectively gating said first ones and said second ones of said input registration signals from said keyboard selector means, said message control means providing first control signals in response to said selective gating thereof, message storage means including second memory means having second stored time data signals therein and being connected to receive said first ones of said input registration signals to provide selected ones of said first stored data signals as second output signals therefrom and third memory means connected to receive said second ones of said input registration signals from said message control means for storage therein and to provide the same as third output signals therefrom in accordance with said selective gating of said message control means, message output logic means having gating devices receiving said second output signals and said third output signals from said second and third memory means, respectively, and said first control signals from said message control means, said gating devices selectively providing either the second or third output signals as fourth output signals therefrom upon receipt of said first control signals, time comparison logic means connected to receive both said first output signals from said first memory means and said second output signals from said message output logic means, said comparison means comparing the same and providing first comparison signals responsive to equal comparisons thereof, respectively, and display control means connected to receive said first comparison signals from said comparison means, first output signals from said clock-calendar means, fourth output signals from said message output logic means for providing said first output signals to said visual display means for display thereon when said first output signals and said second output signals are unequal and providing said fourth output signals to said visual display means for display thereon when said first output signals and said second output signals are equal in response to the receipt of said first comparison signals from said time comparison means.
