Abstract
Abstract A light circuit which is the combination of a laser light source, optical fiber light paths, or more transducers, shutters or other light modulating means and appropriate readout device means which is preferably one which reads out directly in light terms. The transducer imparts information, suitable medical information to the modulator which in turn varies the laser light beam in the optical fiber path. The varied light beam is read directly without any energy converison being necessary.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
132 words
A monitoring system comprising a collimated light source; semitransparent beam splitter means aligned with the beam emitted from said collimated light source for dividing said beam into a plurality of beam portions; first light guide means optically aligned at one end with a first of said beam portions; means for viewing the other end of said first optical light guide means; second optical light guide means optically aligned at one end with a second of said beam portions; transducer means for sensing a variable being monitored; modulating means coupled to said transducer located in the light path intermediate the ends of said second optical light guide means for impressing the transducer sense onto said second beam portion; and remote read out means comprising the end of said second optical light guide means.
Claim 2
Dependent Claim
132 words
A monitoring system comprising a collimated light source; semitransparent beam splitter means aligned with the beam emitted from said collimated light source for dividing said beam into a plurality of beam portions; first light guide means optically aligned at one end with a first of said beam portions; means for viewing the other end of said first optical light guide means; second optical light guide means optically aligned at one end with a second of said beam portions; transducer means for sensing a variable being monitored; modulating means coupled to said transducer located in the light path intermediate the ends of said second optical light guide means for impressing the transducer sense onto said second beam portion; and remote read out means comprising the end of said second optical light guide means.
Claim 3
Dependent Claim
28 words
A monitoring system as claimed in claim 1 wherein said read out means is an optical view of the other enD of said second optical light guide means.
Claim 4
Dependent Claim
74 words
A monitoring system as claimed in claim 1 including a gap means in an intermediate portion of said second optical light guide means, a substantially opaque shutter disposed for interposition in said gap means; an operative connection of said transducer to said shutter adapted to move said shutter into or out of said gap as a function of said transducer sense whereby preventing or permitting, respectively, said laser light beam from crossing said gap.
Claim 5
Dependent Claim
17 words
A monitoring system as claimed in claim 1 wherein said remote read out means comprises an oscillograph.
Claim 6
Dependent Claim
30 words
A monitoring system as claimed in claim 1 including computer means downstream of said modulator adapted to be fed by the modulated light beam in said second optical light guide.
Claim 7
Dependent Claim
35 words
A monitoring system as claimed in claim 3 wherein said transducer is adapted to receive and convey information relative to human life signs and wherein said shutter is operative in response to said life signs.
Claim 8
Dependent Claim
30 words
A monitoring system as claimed in claim 1 wherein said beam splitter means, said light guide means, said remote read out means and said viewing means are all substantially non-electronic.
Claim 9
Dependent Claim
15 words
A monitoring system as claimed in claim 1 wherein said light guide means are Fibers.
Claim 10
Dependent Claim
70 words
A monitoring system as claimed in claim 1 including multiple beam splitter means coverting said light laser beam into multiple beam portions and including multiple second beam portions, multiple transducers, multiple second optical light guide means and multiple modulators, each set of transducer, modulator, light guide means and beam splitter being associated with a single second beam portion to measure and report to said remote read out a separate sense.
Claim 11
Dependent Claim
25 words
A monitoring system as claimed in claim 1 wherein said modulator comprises a spring loaded shutter means and wherein said read out means is digital.
Claim 12
Dependent Claim
16 words
A monitoring system as claimed in claim 1 wherein said columated light source is a laser.
Claim 13
Dependent Claim
62 words
A monitoring system as claimed in claim 1 wherein said second of said beam portions is divided into a first subbeam portion and a second subbeam portion, said modulator located in the optical path of said first subbeam portion, and said second subbeam portion being remotely directly read out as a check on the integrity of the second of said beam portions.
