Two I know of....
Gary Hale makes a "glider" LWB recumbent:

The Sherer trike uses a linear pedaling system:

....I like the function of the Sherer type of system in particular, because
it does not limit the rider to a specific pedal stroke length.... I have a pet theory that (if it were technically possible) bicycle riders would prefer to take lots of little pedal strokes [keeping their legs nearly extended] when cruising over level ground--and they'd take fewer, deeper pedal strokes when climbing hills--just like people do when they are jogging.
