Abstract: An intercourse assembly is configured to enable human user to stimulate sexual intercourse. The apparatus is comprised of two cushions that each have a bullnose cutout on one side that is filled with a cushion bullnose made of a low-resilience polyurethane foam, such that when the cushions are attached, the two bullnose profile outlines are aligned. A formed pathway is made between the two cushion bullnoses to enable the user to simulate intercourse. A motor is attached to one of the bullnoses and configured to vibrate to enhance the user's enjoyment. Each cushion has an outer covering that features three hook and loop fasteners that enable the two cushions to attach to each other, as well as secure a washable liner to the apparatus through the use of two straps that each have two hook and loop fasteners on each end.

Abstract: A multiport bridge controlled by the intelligence of a programmed microcontroller selectively channels audio from a plurality of input ports to a plurality of output ports including a room program output. Coupled to one of the bridge input ports is at least one gated microphone mixer, including multiple microphone channels and an acoustical echo canceller. Expandability is provided by a second, third or up to n microphone mixers each having a separate echo canceller for the associated group of microphone inputs.
