Photo-optic transducing head assembly
First Claim
1. A photoelectric transducer assembly for detecting shifts in radiant energy at a working face thereof comprising, in combination:
- (a) a generally rectangular printed circuit card means having active and passive electrical components, including radiant energy source means and a radiant energy responsive means disposed thereon at spaced apart locations along a common side edge of said card;
(b) a rectangular frame member having four mutually perpendicular sidewalls defining a central opening, one of said sidewalls having spaced apart radiant energy transmissive windows;
(c) said printed circuit card means being supported within said central opening of said frame member with said radiant energy source means and said radiant energy responsive means on said common side edge of said card means being in separate alignment with said spaced apart radiant energy transmissive windows; and
(d) a bifurcated radiant energy transmissive guide means secured to said frame member, the branches of said bifurcated guide means being in alignment with said spaced apart radiant energy transmissive windows;
said guide means including a stem portion leading to said working face of said transducer assembly.

Abstract
A photo-optic transducer assembly comprising a frame constructed to surround the peripheral edges of a ceramic hybrid circuit card such that a radiation source and a radiation responsive element coupled to said hybrid circuit card are appropriately aligned with a photo-optic light pipe assembly, also supported by said frame, the light pipe element leading to a location where sensing is to occur. The hybrid circuit card contains active and passive components (including one or more integrated circuit chips) on it for processing signals indicative of conditions being irradiated by a source of radiant energy.

10. A photoelectric transducing head assembly comprising, in combination:
-
(a) a hybrid electronic circuit disposed on a ceramic substrate, said circuit including active and passive components, including a light-emitting diode and a photo-transistor disposed at spaced apart locations proximate a side edge of said substrate, said components being interconnected by a pattern of printed conductors on said substrate; (b) a plurality of regularly spaced terminal pins connected at one end to said pattern of printed conductors on said substrate and extending from another side edge of said substrate; and (c) a generally rectangular frame member having four sidewalls defining a central opening for receiving said ceramic substrate therein, said frame member having a plurality of regularly spaced notches along one sidewall for receiving said plurality of terminal pins when said ceramic substrate is fitted into said frame, another sidewall of said frame member including light transmissive paths therethrough in alignment with said spaced apart locations. - View Dependent Claims (11, 12, 13, 14)
