Abstract
Abstract A multiple coding system in which a large number of different types of remote sensing units may be monitored by a single station, each sensing unit being identified by its unique code signal. The code signal is produced by generating a series of marker pulses in which only a predetermined combination of the pulses are followed by a code pulse. The monitoring station interprets the predetermined combination as a series of binary numbers identifing the sensing unit, decodes the binary numbers to decimal numbers, and displays the numbers on a panel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
A coding system comprising in combination: remote condition sensing switch means; marker pulse generating means connected to and operable to be activated by said condition sensing means; coded shiftable gating means; first delay means connected between said marker pulse generating means and said coded shiftable gating means operable to pass with some delay the pulses to said coded gating means, said coding means connected to pass at least some of the pulses from said generating means in a predetermined coded sequence; a monitoring station; transmission means between said gating means and said monitoring station so as to transmit the pulses therebetween; analyzing means in said monitoring station operable to determine which of the marker pulses is followed by a delayed pulse; and decoding means in said monitoring station connected to said analyzing means and operable to display in an understandable form the particular remote condition sensing means which is activated.
Claim 2
Dependent Claim
150 words
A coding system comprising in combination: remote condition sensing switch means; marker pulse generating means connected to and operable to be activated by said condition sensing means; coded shiftable gating means; first delay means connected between said marker pulse generating means and said coded shiftable gating means operable to pass with some delay the pulses to said coded gating means, said coding means connected to pass at least some of the pulses from said generating means in a predetermined coded sequence; a monitoring station; transmission means between said gating means and said monitoring station so as to transmit the pulses therebetween; analyzing means in said monitoring station operable to determine which of the marker pulses is followed by a delayed pulse; and decoding means in said monitoring station connected to said analyzing means and operable to display in an understandable form the particular remote condition sensing means which is activated.
Claim 3
Dependent Claim
39 words
The system of claim 1 in which said coded shiftable gating means comprises a gate activated by some of the outputs of a shift register said shift register being advanced by the delayed pulses from said first delay means.
Claim 4
Dependent Claim
32 words
The system of claim 2 in which said analyzing means comprises a coincident pulse operable gate connected to receive marker pulses from said transmission means directly and through a second delay means.
Claim 5
Dependent Claim
44 words
The system of claim 3 including a second shift register advanced by marker pulses from said transmission means and operable to open a series of gates to pass pulses from said coincident pulse operable gate so as to activate a series of electronic switches.
Claim 6
Dependent Claim
45 words
The system of claim 4 in which said decoding means comprises trigger circuit means operable to pass the outputs of said electronic switches to a binary to decimal decoder at the end of the scan of said second shift register over said series of gates.
Claim 7
Dependent Claim
31 words
The system of claim 5 including further a display panel having indicator means thereon connected to said decoder to show the decoded number represented by the outputs of said electronic switches.
Claim 8
Dependent Claim
56 words
The system of claim 6 including second trigger means connected to said second shift register and to a third shift register to advance said third shift register, said third shift register changing the output of said decoder to different indicator means on said display panel upon the completion of each scan by said second shift register.
Claim 9
Dependent Claim
15 words
The system of claim 7 in which said transmission means comprises radio transmitter and receivers.
Claim 10
Dependent Claim
27 words
The system of claim 7 in which said indicator means comprises lights controlled by electronic switches which are in turn activated by gates controlled by said decoder.
