Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
66 words
A target motion sensitive firable device comprising a surgical laser for firing at a target, user operable switching means for activating said surgical laser when operated by a user, motion detector means interconnecting said switching means and said surgical laser for preventing said switching means from activating said surgical laser in response to the operation by a user when a motion is detected in the target.
Claim 2
Dependent Claim
66 words
A target motion sensitive firable device comprising a surgical laser for firing at a target, user operable switching means for activating said surgical laser when operated by a user, motion detector means interconnecting said switching means and said surgical laser for preventing said switching means from activating said surgical laser in response to the operation by a user when a motion is detected in the target.
Claim 3
Dependent Claim
25 words
The firable device of claim 1 wherein said motion detector means is means for detecting a motion having a velocity greater than a given velocity.
Claim 4
Dependent Claim
25 words
The firable device of claim 1 wherein said motion detector means is means for detecting a motion having a duration greater than a given duration.
Claim 5
Dependent Claim
37 words
The firable device of claim 1 wherein said motion detector means comprises a matrix of photoelectric devices each having optically sensitive areas with an operative dimension equal to the average width of a retina blood vessel image.
Claim 6
Dependent Claim
39 words
The firable device of claim 1 wherein said motion detector means further comprises a plurality of signal processing means each connected to one of the photoelectric devices for producing a DC signal related to the motion of the target.
Claim 7
Dependent Claim
30 words
The firable device of claim 5 wherein said signal processing means includes high pass filter means for selecting velocities of motion of the target greater then a said given velocity.
Claim 8
Dependent Claim
32 words
The firable devices of claim 5 wherein said motion detector means comprises signal summing means for adding all the DC signals from all of said signal processing means to a composite signal.
Claim 9
Dependent Claim
32 words
The firable device of claim 6 wherein said motion detector means comprises signal summing means for adding all the DC signals from all of said signal processing means to a composite signal.
Claim 10
Dependent Claim
40 words
The firable device of claim 7 wherein said motion detecting means comprises latchable comparator means connected to said signal summing means and operative in accordance with the amplitude of the composite signal to control the activation of said firing means.
Claim 11
Dependent Claim
32 words
The firable device of claim 1 wherein said switching means includes a mechanically operable switch having a mechanically resistive intermediate position which must be overcome before said switching means is unconditionally operative.
