Abstract
Abstract A system for displaying information from a plurality of metering registers, comprising a plurality of indicators, each of said indicators having a plurality of illumination means which, when actuated in a predetermined order, present symbols, gating means, and control means for providing signals to scan each of said registers in a predetermined order and then to control said gating means to provide signals representative of signals from said registers in the same said predetermined order, to provide signals to actuate said illumination means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
In a system for reading out information stored in a plurality of metering registers where each register includes a plurality of electrical contacts which are adapted to be energized in accordance with information stored in the register and where one of the contacts is energized upon application of an electrical potential to the register, the improvement comprising a plurality of display devices, each of said display devices having a plurality of segments adapted to be selectively energized and illuminated to represent the data in an associated one of said metering registers, means providing a plurality of sequentially occurring scanning signals, means for sequentially scanning the plurality of metering registers by applying said sequential signals thereto and deriving a signal indicative of the data stored therein, coding means for operating on said derived signals in accordance with the scanning sequence to sequentially provide encoded signals indicative of the data in each register and decoding means responsive to the coded signals and the scanning signals for applying energizing signals to segments of said display devices in the same sequence in which said registers are scanned.
Claim 2
Dependent Claim
183 words
In a system for reading out information stored in a plurality of metering registers where each register includes a plurality of electrical contacts which are adapted to be energized in accordance with information stored in the register and where one of the contacts is energized upon application of an electrical potential to the register, the improvement comprising a plurality of display devices, each of said display devices having a plurality of segments adapted to be selectively energized and illuminated to represent the data in an associated one of said metering registers, means providing a plurality of sequentially occurring scanning signals, means for sequentially scanning the plurality of metering registers by applying said sequential signals thereto and deriving a signal indicative of the data stored therein, coding means for operating on said derived signals in accordance with the scanning sequence to sequentially provide encoded signals indicative of the data in each register and decoding means responsive to the coded signals and the scanning signals for applying energizing signals to segments of said display devices in the same sequence in which said registers are scanned.
Claim 3
Dependent Claim
22 words
The system of claim 1 wherein said means for sequentially applying signals is repetitively operative to scan said registers in the sequence.
Claim 4
Dependent Claim
90 words
A system according to claim 1, in which the means for applying a potential comprises a clock, a first bistable multivibrator having first and second output terminals and an input terminal coupled to said clock, an inverting amplifier coupled to the second output terminal of said first bistable multivibrator, a second bistable multivibrator having first and second output terminals and an input terminal coupled to said inverting amplifier, anD a plurality of gates arranged to sense the output signals of said multivibrators and provide a plurality of sequentially occurring signals.
Claim 5
Dependent Claim
21 words
A system according to claim 3 further including means for coupling the sequentially occurring signals from said gates to said registers.
Claim 6
Dependent Claim
47 words
A system according to claim 1, wherein said coding means converts information from ten data lines into information suitable for transmission over seven data lines, said seven data lines providing signals to said decoding means for each register to operate each of said plurality of display devices.
