Abstract: A supine cycling exercise machine includes a frame attached to a horizontal base and a rotation driving assembly supported by the frame. The driving assembly includes a rotatable crankshaft and two crankarms with proximal ends thereof attached to opposite ends of the crankshaft, with two pedals attached to distal ends of the crankarms. One or more crankarm includes a redirection connection mechanism at the proximal end thereof, and such a crankarm is adapted to be repositioned by an exerciser between an opposing and a parallel orientation relative to the other crankarm. The exercise machine can be used for two different cycling exercises, with either a reciprocating motion or a parallel motion of the exerciser's feet.

Abstract: A fast change electric transformer connector is disclosed, which includes a cable connector having a cable attachment section, a connector extension connected to the cable attachment section, and a stud slide adaptor connected to a side of the connector extension for slidably attaching the cable connector to a transformer stud; and a stud screw adaptor complimentary to a transformer stud. The cable attachment section includes a cable receiving body having multiple receiving slots for receiving cables; and multiple removable sliding cable fastening blocks disposed within the receiving slots for fastening the cables. Each sliding cable fastening block can be slid in or out from the receiving slot for conveniently installing a large cable. Also disclosed are a transformer connector and a transformer adaptor, which have an adaptor extension for connecting between the transformer stud and the cable connection portion of the connector/adaptor, for use when shorted cables are cut.

Abstract: A fast change electric transformer connector is disclosed, which includes a cable connector having a cable attachment body with a plurality of cable attachment ports, a connector extension connected to the cable attachment body, and a stud slide adaptor connected to a side of the connector extension; and a stud screw adaptor complimentary to a transformer stud, for connecting the transformer stud and the stud slide adaptor of the cable connector. Further disclosed is a transformer adaptor, which includes an inter-connector having a screw threaded end for connecting to a cable connector, and a stud slide adaptor for adapting to a transformer stud; and a stud screw adaptor for connecting the transformer stud and the stud slide adaptor of the inter-connector. Using the transformer connector or adaptor of the present invention, a transformer can be replaced rapidly without disconnecting cables.
