Abstract
Abstract A motion transducer includes a series of lights in a register, the individual lights being energized by timed electronic circuits controlled by the sequential change in energization of three spaced light receivers in line to receive light beams from three similarly spaced light sources and all stationary with respect to one of two relatively movable members, the outer relatively movable member being in part opaque and in part transparent according to a code to pass but one light beam at a time according to the relative position of said members, except at one end position wherein two light beams are simultaneously passed to reset the register.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
127 words
A motion transducer comprising a relatively stationary yoke having spaced arms, a rectilinear strap movable along a longitudinal axis between the arms of said yoke, means on one arm of said yoke for projecting a plurality of discrete spaced light beams toward a corresponding plurality of light receivers on the other arm of said yoke, said beams being spaced parallel to said axis, means included in said strap for blocking all but one of said light beams corresponding to the momentary relative position of said yoke and said strap, an indicating register, and logic means responsive to a change from one to another of said light receivers that is unblocked, as a result of movement of said strap, For controlling a corresponding actuation of said indicating register.
Claim 2
Dependent Claim
127 words
A motion transducer comprising a relatively stationary yoke having spaced arms, a rectilinear strap movable along a longitudinal axis between the arms of said yoke, means on one arm of said yoke for projecting a plurality of discrete spaced light beams toward a corresponding plurality of light receivers on the other arm of said yoke, said beams being spaced parallel to said axis, means included in said strap for blocking all but one of said light beams corresponding to the momentary relative position of said yoke and said strap, an indicating register, and logic means responsive to a change from one to another of said light receivers that is unblocked, as a result of movement of said strap, For controlling a corresponding actuation of said indicating register.
Claim 3
Dependent Claim
63 words
A motion transducer as in claim 1 in which there are three of said projecting means and three of said light receivers, and said blocking means is an opaque portion of said strap effective to block two of said light beams at a time and said strap having an opening therein effective to pass but one of said light beams at said time.
Claim 4
Dependent Claim
59 words
A motion transducer as in claim 2 in which said projecting means and said light receivers are separated by equal spaces in the direction of translation of said strap relative to said yoke and said strap has a plurality of said openings therein spaced apart in the direction of said translation a distance equal to three of said spaces.
Claim 5
Dependent Claim
57 words
A motion transducer as in claim 1 in which said indicating register includes direction indicating means to indicate the direction of movement of said strap relative to said yoke in either of two opposite directions, said logic means also being responsive to sequential changes in energization of said light receivers for correspondingly operating said direction indicating means.
Claim 6
Dependent Claim
38 words
A motion transducer as in claim 4 in which said indicating register includes a plurality of indicators, and means responsive to sequential changes in energization of said light receivers for correspondingly operating corresponding individual ones of said indicators.
Claim 7
Dependent Claim
26 words
A motion transducer as in claim 1 in which said means for producing actuation of said register includes a device for timing actuation of said register.
Claim 8
Dependent Claim
29 words
A motion transducer as in claim 1 including means for resetting said register, said strap including an additional opening in a predetermined location for actuating said direction indicating means.
Claim 9
Dependent Claim
72 words
A motion transducer as in claim 7 in which said additional opening is adjacent one end of said strap and is positioned with respect to one of said others of said openings so that said additional opening and said one opening pass two of said light beams at the same time to two of said light receivers, and in which simultaneous actuation of said two light receivers actuates said direction indicating means.
Claim 10
Dependent Claim
51 words
A motion transducer as in claim 1 in which said indicating register includes a series of indicator lights arranged in a line having two ends, and in which said actuation means includes selecting means for energizing said indicator lights beginning at either chosen one of said two ends of said line.
