US4568935A — Data reporting system

Claim 1

Independent Claim 134 words

In a data gathering system, in combination: a data gathering station including a microprocessor, a plurality of data sources, and multiplexer means connecting said sources to said microprocessor so that said microprocessor may give outputs digitally representative of said sources; a data transmission line including a pair of conductors; means, including switch means, for establishing a conductive path between said conductors, so that when said path is completed a pulse of current may flow between said conductors, said path including lamp means so that when current flows in said path said lamp is illuminated; means periodically connecting said switch means to said microprocessor for actuation in accordance with the output thereof; means energizable to prevent illumination of said lamp means without interrupting said path; and condition responsive means for periodically energizing the last-named means.

Claim 2

Dependent Claim 134 words

In a data gathering system, in combination: a data gathering station including a microprocessor, a plurality of data sources, and multiplexer means connecting said sources to said microprocessor so that said microprocessor may give outputs digitally representative of said sources; a data transmission line including a pair of conductors; means, including switch means, for establishing a conductive path between said conductors, so that when said path is completed a pulse of current may flow between said conductors, said path including lamp means so that when current flows in said path said lamp is illuminated; means periodically connecting said switch means to said microprocessor for actuation in accordance with the output thereof; means energizable to prevent illumination of said lamp means without interrupting said path; and condition responsive means for periodically energizing the last-named means.

Claim 3

Dependent Claim 32 words

A system according to claim 1 in which the periodicity of said condition responsive means is in phase with, but is a multiple of, the periodicity of actuation of said switch means.

Claim 4

Dependent Claim 22 words

A system according to claim 2 in which the periodicity is changeable dependent upon the condition sensed by said condition responsive means.

Claim 5

Dependent Claim 97 words

An alarm system for detecting normal, trouble, and alarm conditions, for displaying said conditions locally, and for transmitting at least some of said conditions remotely, said system comprising: light emitting means; sensor means; and, condition detection means connected to said sensor means and to said light emitting means for detecting normal, trouble, and alarm conditions of said sensor means and for energizing said light emitting means at a frequency depending upon said condition to display said conditions locally, said condition detection means having transmitter means for transmitting at least some of said conditions to a remote location.

Claim 6

Dependent Claim 97 words

An alarm system for detecting normal, trouble, and alarm conditions, for displaying said conditions locally, and for transmitting at least some of said conditions remotely, said system comprising: light emitting means; sensor means; and, condition detection means connected to said sensor means and to said light emitting means for detecting normal, trouble, and alarm conditions of said sensor means and for energizing said light emitting means at a frequency depending upon said condition to display said conditions locally, said condition detection means having transmitter means for transmitting at least some of said conditions to a remote location.

Claim 7

Dependent Claim 49 words

Supervisory apparatus comprising an alarm device, means connected to interrogate said device repeatedly to derive successive signals from said device representative of the state each time said device is interrogated, and condition-responsive means in said device for selectively preventing individual illuminations of said lamp without disablement of said apparatus.

Claim 8

Dependent Claim 49 words

Supervisory apparatus comprising an alarm device, means connected to interrogate said device repeatedly to derive successive signals from said device representative of the state each time said device is interrogated, and condition-responsive means in said device for selectively preventing individual illuminations of said lamp without disablement of said apparatus.

Claim 9

Dependent Claim 18 words

Apparatus according to claim 5 in which the condition responsive means prevents every second illumination of said lamp.

Claim 10

Dependent Claim 19 words

Apparatus according to claim 5 in which the condition responsive means prevents two out of every three successive illuminations.
