Abstract
Abstract A monitoring device and method for determining the present demand of electrical energy consumed over a predetermined time period which includes an adjustable reflective scanner or sensor mounted exteriorily of an electric meter for sensing and determining the speed of the rotating disc of a conventional electric meter. The arrangement is such that the scanner or sensor detects the revolutions of the meter disc and emits a signal or signals which are amplified and fed into a counting device which includes a memory and in conjunction with a printer prints the time of day, the date (at midnight) and the number of revolutions of the rotating meter disc which is stored as recorded in memory for a given unit of time. The counting device, memory and printer are embodied in a printing calculator interfaced with timing and scanning means.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
205 words
A device for monitoring peak demand electric usage from an electric usage meter having a rotating disc and a peak demand meter integrated therewith, said peak demand meter being mechanically activated and designed to be reset if said peak demand electric usage is not maintained for a predetermined continuous time interval, said device comprising means for sensing rotation of said disc, timing means, and a printing calculator containing counting, memory and printing means, said counting means being adapted to receive signals from said sensor and to count rotations of said disc, and said memory means retaining a cumulated total of said counted rotations and wherein said printing means is adapted to print said cumulated total of rotations after a period of time no longer than said predetermined continuous time interval of said peak demand meter, whereby the number of rotations during said period of time can be ascertained; and said printing means being adapted to be activated by said timing means to print out the time together with said cumulated total of rotations whereby electric usage for said time period can be ascertained and wherein determination of electric usage during said period of time by said device determines the accuracy of the peak demand meter.
Claim 2
Independent Claim
205 words
A device for monitoring peak demand electric usage from an electric usage meter having a rotating disc and a peak demand meter integrated therewith, said peak demand meter being mechanically activated and designed to be reset if said peak demand electric usage is not maintained for a predetermined continuous time interval, said device comprising means for sensing rotation of said disc, timing means, and a printing calculator containing counting, memory and printing means, said counting means being adapted to receive signals from said sensor and to count rotations of said disc, and said memory means retaining a cumulated total of said counted rotations and wherein said printing means is adapted to print said cumulated total of rotations after a period of time no longer than said predetermined continuous time interval of said peak demand meter, whereby the number of rotations during said period of time can be ascertained; and said printing means being adapted to be activated by said timing means to print out the time together with said cumulated total of rotations whereby electric usage for said time period can be ascertained and wherein determination of electric usage during said period of time by said device determines the accuracy of the peak demand meter.
Claim 3
Dependent Claim
47 words
The device of claim 1 wherein said sensor comprises an optical scanner which senses changes in the reflective index of said disc with said sensor comprising a phototransistor surrounded by optical fibers through which light is transmitted and a lens positioned between said disc and said phototransistor.
Claim 4
Dependent Claim
15 words
The device of claim 2 wherein said scanner is positioned exteriorily of said meter casing.
Claim 5
Dependent Claim
20 words
The device of claim 1 wherein said timing means comprises a seven segment output clock/calendar non-multiplexed direct drive MOS IC.
Claim 6
Dependent Claim
17 words
The device of claim 1 wherein said timing means comprises a BCD output non-multiplexed clock/calendar MOS IC.
Claim 7
Dependent Claim
69 words
The device of claim 1 wherein said counting means comprises a number key and the plus key of said calculator whereby each repeated activation of said plus key, after said number key is activated, adds said number to the memory of said calculator which calculator memory comprises said memory means and wherein each signal from said sensor activates said plus key with said calculator and sensor being interfaced thereby.
Claim 8
Dependent Claim
46 words
The device of claim 6 wherein said calculator comprises activation means for printing out an entered number into said calculator without change thereof, whereby said time is entered into said calculator at the end of said predetermined period as said entered number and is printed out.
Claim 9
Dependent Claim
23 words
The device of claim 6 wherein said calculator comprises activation means for printing out said cumulated memory and erasing it upon said printing.
Claim 10
Dependent Claim
24 words
The device of claim 7 wherein said means for printing out the time further functions to print out the calendar date during the day.
Claim 11
Dependent Claim
52 words
The device of claim 1 wherein said timing means comprises a non-multiplexed clock/calendar MOS IC and wherein said timing means is interfaced with said calculator by multiplexing a BCD output from said MOS IC to a BCD one-of-ten decoder which is in turn connected to activate numerical keys 0-9 of said calculator.
Claim 12
Dependent Claim
52 words
The device of claim 9 wherein said timing means comprises a non-multiplexed clock/calendar MOS IC and wherein said timing means is interfaced with said calculator by multiplexing a BCD output from said MOS IC to a BCD one-of-ten decoder which is in turn connected to activate numerical keys 0-9 of said calculator.
Claim 13
Dependent Claim
26 words
The device of claim 11 wherein the printout of said time and said date is distant from the portion of the printout containing said cumulated total.
