Abstract
Abstract A meeting cost calculator and timer is shown for displaying the total cost of a meeting and the elapsed time thereof. Input switches, each associated with a class of attendee, actuate an adjustable rate indicator which applies its digital signal to an arithmetic logic unit and then to an accumulator in the form of a memory register. A second set of switches add or subtract the rate applied to the accumulator depending whether the attendee is entering or leaving the meeting. A display displays the total rate of the attendees over a period of time as the total cost of the meeting.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
106 words
A device for calculating the cost and time of a meeting and displaying the cost thereof, comprising: input means for selecting the time based compensation rate of each meeting attendee; memory means connected to said input means for accumulating the instantaneous selected compensation rates of all meeting attendees; timing means for timing the meeting, said timing means selectively enabled by said input means and operative to activate said memory means for accumulating the selected compensation rates of all meeting attendees over a time period initiated by said input means; and display means connected to said memory means for displaying the accumulated selected rates of said attendees.
Claim 2
Independent Claim
106 words
A device for calculating the cost and time of a meeting and displaying the cost thereof, comprising: input means for selecting the time based compensation rate of each meeting attendee; memory means connected to said input means for accumulating the instantaneous selected compensation rates of all meeting attendees; timing means for timing the meeting, said timing means selectively enabled by said input means and operative to activate said memory means for accumulating the selected compensation rates of all meeting attendees over a time period initiated by said input means; and display means connected to said memory means for displaying the accumulated selected rates of said attendees.
Claim 3
Dependent Claim
43 words
A device, as claimed in claim 1, additionally comprising: a second display means connected to said timing means for displaying real time; and a third display means connected to said timing means for displaying elapsed time after being enabled by said input means.
Claim 4
Dependent Claim
32 words
A device, as claimed in claim 2, additionally comprising: a printer connected to said memory means and said timing means for printing said accumulated meeting cost, elapsed time and real time, respectively.
Claim 5
Dependent Claim
36 words
A device, as claimed in claim 1, wherein said input means include: a plurality of input switches; and a plurality of pre-adjusted rate switches selectively enabled by said input switches and connected to said memory means.
Claim 6
Dependent Claim
35 words
A device, as claimed in claim 1, wherein said input means additionally comprises: an input add switch connected to said memory means to selectively add said selected rate to said means for accumulating said rates.
Claim 7
Dependent Claim
36 words
A device, as claimed in claim 5, wherein said input subtract means additionally comprises: an input subtract switch connected to said memory means to selectively subtract said selected rate from said means for accumulating said rates.
Claim 8
Dependent Claim
51 words
A device, as claimed in claim 1, wherein said timing means additionally comprises: clock means enabled by said input means; and second memory means driven by said clock means for accumulating the accumulated selected rates from said first mentioned memory means over a period of time controlled by said clock means.
Claim 9
Dependent Claim
30 words
A device, as claimed in claim 7, wherein said clock means is disabled by said first mentioned memory means when the accumulated selected rates stored therein attain a prescribed value.
Claim 10
Dependent Claim
35 words
A device, as claimed in claim 1, additionally comprising: delay means connected between said timing means and said display means to delay the display of the accumulated selected rate until after a predetermined elapsed time.
Claim 11
Independent Claim
190 words
A device for calculating the cost and time of a meeting and displaying the total cost thereof, comprising: a plurality of rate switch means each of which reflects the average cost per unit of time (i.e. rate) of a particular class of persons expected to attend a meeting; an arithmetic logic unit (36) connected to said plurality of rate switch means; a plurality of input switch means (20) each connected to energize one respective rate switch means thereby to select and apply the respective rate to said arithmetic logic unit; memory means for accumulating and storing each rate as applied to said arithmetic logic unit; clock means selectively enabled by said plurality of input switch means; a second arithmetic logic unit connected to said memory means and energized periodically by said clock means; a second memory means for accumulating and storing said respective rate from said first mentioned memory means during consecutive time units as determined by said clock means; and display means connected to said second memory means for displaying the total accumulated, selected rates of said attendees during said time units as a total cost of said meeting.
Claim 12
Independent Claim
190 words
A device for calculating the cost and time of a meeting and displaying the total cost thereof, comprising: a plurality of rate switch means each of which reflects the average cost per unit of time (i.e. rate) of a particular class of persons expected to attend a meeting; an arithmetic logic unit (36) connected to said plurality of rate switch means; a plurality of input switch means (20) each connected to energize one respective rate switch means thereby to select and apply the respective rate to said arithmetic logic unit; memory means for accumulating and storing each rate as applied to said arithmetic logic unit; clock means selectively enabled by said plurality of input switch means; a second arithmetic logic unit connected to said memory means and energized periodically by said clock means; a second memory means for accumulating and storing said respective rate from said first mentioned memory means during consecutive time units as determined by said clock means; and display means connected to said second memory means for displaying the total accumulated, selected rates of said attendees during said time units as a total cost of said meeting.
Claim 13
Dependent Claim
29 words
A device, as claimed in claim 10, additionally comprising: an elapsed timer connected to said clock means; and a display connected to said elapsed timer to display elapsed time.
Claim 14
Dependent Claim
30 words
A device, as claimed in claim 10, wherein said plurality of rate switch means include adjustable switch means to permit periodic adjustment of the rate of each class of attendees.
Claim 15
Dependent Claim
40 words
A device, as claimed in claim 12, wherein said clock means is disabled by said first mentioned memory means when the accumulated rate stored therein reaches a prescribed value signifying that the last of said attendees has exited said meeting.
Claim 16
Dependent Claim
99 words
A device, as claimed in claim 10, wherein said plurality of input switch means includes: a first switch means including at least one switch for each class of meeting attendees; a second switch means to add the rate of said class selected by said attendee to said first mentioned memory means through said first mentioned arithmetic logic unit as said attendee enters said meeting; and a third switch means to subtract the rate of said class selected by said attendee from said first mentioned memory means through said first mentioned arithmetic logic unit as said attendee exits said meeting.
Claim 17
Dependent Claim
31 words
