Abstract: An optical transceiver may include a circuit board, lasers, and a PLC including optical multiplexers and demultiplexers. The PLC may be coupled to fiber optic lines at a forward edge of the PLC, with a rear edge of the PLC receiving light for transmission generated by the lasers. Light received at the forward edge of the PLC may be demultiplexed into data channels and routed to a top surface of the PLC for optoelectronic conversion by photodetectors. In some embodiments each data channel is routed into a corresponding plurality of waveguides, with each of the corresponding plurality of waveguides providing light to the same photodetector. In some embodiments at least some receive side electronic circuitry, other than photodetectors, is stacked on top of the PLC.

Abstract: Paint filtering apparatus for supporting a filter medium, such as foraminous cloth or the like, above a paint pail. The apparatus includes an impervious plate larger than the mouth of the paint pail and legs for supporting the plate above a surface on which the paint pail can be rested. The plate defines a circular opening having a diameter smaller than the diameter of the mouth of the paint pail. A cylindric rim that is sized to fit within the hole in the plate and having protrusions fastened thereto for bearing on the plate to retain the rim in place. Above the protrusions the rim defines an annular groove, and there is a strap that can be placed in the groove to retain the filter medium within the groove throughout the extent thereof. The rim is smaller than the diameter of a paint bucket so that a paint bucket can be rested on the rim in an inverted position to afford draining of the same without continuing attention.
