Abstract
Abstract An illuminated master calendar is disclosed having a short depth profile and suitable for mounting on a wall. A front panel of the housing has a first group of momentary contact touch sensitive switches mounted thereon with each switch having a transparent pushbutton face through which illuminated indicia are visible when the switch is depressed. The first group of switches is representative of each of the days of the month, a similar second group of switches is provided for each of the months of the year, and a third group for each of the days of the week. A circuit is provided for illuminating a light source behind each of the indicia when the corresponding switch is touched. The circuit also maintains illumination of the indicia after the switch is released. A reset switch and associated reset circuit are connected for extinguishing all illuminated indicia and preparing each of the switches with associated indicia for reactivation. A tape recorder memory system may also be associated with the calender such that predetermined segments of a tape corresponding to each of the days of the month are provided for recording of messages corresponding to each of such days.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
213 words
An illuminated master calendar comprising: (a) a wall mounting housing having a depth of less than two inches; (b) a front panel for the housing; (c) a plurality of momentary contact touch sensitive switches arranged in a 5 row and 7 column monthly calendar format on the front panel with indicia at each switch location for indicating each of the days of a month; (d) a plurality of momentary contact touch sensitive switches arranged in a horizontal row on the front panel with indicia at each switch location for indicating each of the months of a year, and an additional horizontal row of touch sensitive switches with indicia at each switch location for indicating days of the week in alignment with the 7 columns of the calendar format; (e) a reset switch on the front panel; (f) illuminator means directly at each switch for illuminating only the associated indicia directly at the switch; (g) circuit means for illuminating the illumination means when the corresponding switch is touched and maintaining the illumination after the switch is released; and (h) reset circuit means connected to said reset switch for controlling said circuit means so as to extinguish all illuminated illumination means and prepare each of said illumination means for reactivation by corresponding touch sensitive switches.

Claim 3
Dependent Claim
43 words
The calendar of claim 1 in which a switch button member having a transparent face activates each of said touch sensitive switches, said associated indicia is visible through the transparent face, and indicia is positioned between the transparent face and the illumination means.
Claim 4
Dependent Claim
35 words
The calendar of claim 1 in which a switch for periodic flashing is mounted on the front panel and connects with oscillating circuit means for causing illumination means which have been activated to periodically flash.
Claim 5
Dependent Claim
38 words
The calendar of claim 3 in which said switch for periodic flashing is a touch sensitive momentary contact switch and circuit means are provided for activating the oscillating circuit means when said switch for periodic flashing is released.
Claim 6
Dependent Claim
31 words
The calendar of claim 1 in which a plurality of momentary contact touch sensitive switches are provided on the front panel with indicia associated therewith for indicating days of the week.
Claim 7
Dependent Claim
64 words
The calendar of claim 1 in which a memory means is provided in the housing for recording messages on corresponding portions of a recording medium corresponding to each of the days of the month, and indicator means connected to the memory means for permitting access to the portion of the recording medium corresponding to a day of the month illuminated on the front panel.
Claim 8
Dependent Claim
62 words
The calendar of claim 6 in which the recording medium comprises a tape with equal time interval portions set aside for each of the days of the month and said indicating means comprises a wheel with each of the days of the month printed thereon, said wheel being connected by gear means to a portion of a tape drive for the tape.
Claim 9
Independent Claim
142 words
A system for recording and playing back messages corresponding to dates of a calendar month, comprising: a tape recorder having means for recording and playback of message intervals on recording tape driven by a tape drive; each message interval corresponding to a single day of a month; said tape recorder having a counter means coupled to the tape drive, said counter means having the numerals 1 through 31 as a display indicia representing days of the month and for counting said message intervals during winding of the tape by days of the month to permit an operator to position the recording tape at a message interval corresponding to a day of the month for which the message interval is to be recorded on or played back; and a manually settable display means for indicating one of the twelve months of the year.
Claim 10
Independent Claim
142 words
A system for recording and playing back messages corresponding to dates of a calendar month, comprising: a tape recorder having means for recording and playback of message intervals on recording tape driven by a tape drive; each message interval corresponding to a single day of a month; said tape recorder having a counter means coupled to the tape drive, said counter means having the numerals 1 through 31 as a display indicia representing days of the month and for counting said message intervals during winding of the tape by days of the month to permit an operator to position the recording tape at a message interval corresponding to a day of the month for which the message interval is to be recorded on or played back; and a manually settable display means for indicating one of the twelve months of the year.
Claim 11
Independent Claim
213 words
A system for recording and playing back messages corresponding to dates of a calendar month, comprising: a tape recorder having means for recording and playback of message intervals on recording tape driven by a tape drive; each message interval corresponding to a single day of a month; said tape recorder having a counter means coupled to the tape drive, said counter means having the numerals 1 through 31 as a display indicia representing days of the month and for counting said message intervals during winding of the tape by days of the month to permit an operator to position the recording tape at a message interval corresponding to a day of the month for which the message interval is to be recorded on or played back; a manually settable display means for indicating one of the twelve months of the year; and an illuminated master calendar in a housing which commonly contains said tape recorder adjacent the master calendar, said master calendar having a plurality of momentary contact touch sensitive switches, and illumination means at each switch location for illuminating an indicia representing one of the days of the month corresponding to the switch touched, the illumination means serving as a visual guide for an operator when referencing one of said message intervals.
