摘要:
A toilet set can be removably attached to a toilet fixture using a system having an attachment body and a post with laterally mateable portions. The post has a rod portion extendable through a mounting hole of the toilet fixture and a post engagement portion. The attachment body has a pivot portion, a movable closure, and a receiving opening. The post engagement portion is defined by radially oriented features, such as disc or ring-shaped portions of different diameters. A portion of the periphery of the receiving opening has features with contours inversely shaped with respect to the features of the post engagement portion so that the attachment body engagement portion is laterally mateable with the post engagement portion. The closure is movable between a closed position preventing disengagement of the attachment body and the post and an open position enabling disengagement of the attachment body from the post.

Concepts for conveniently arranging devices for the transduction of signals to and from voltage and current domains to infrared radiation domains is described. Specifically, optoelectronic components and methods of making the same are described. In one aspect, the optoelectronic component includes a base substrate having a pair of angled (or substantially perpendicular) faces with electrical traces extending therebetween. A semiconductor chip assembly is mounted on the first face of the base substrate and a photonic device is mounted on the second face. Both the semiconductor chip assembly and the photonic device are electrically connected to traces on the base substrate. The semiconductor chip assembly is generally arranged to be electrically connected to external devices. The photonic devices are generally arranged to optically communicate with one or more optical fibers. The described structure may be used with a wide variety of photonic devices. In some embodiments the base substrate is formed from a ceramic material having the electrical traces formed thereon. In other implementations the substrate includes a backing block having a flexible printed circuit substrate adhered thereto.
