Abstract: A pad system for using in training for martial arts is disclosed, and includes a long chamber having a first flexible sheath that surrounds a first cushioning pad made with a relatively rigid and firm foam material to prevent penetration and deflection thereof. A short chamber includes a second flexible sheath that surrounds a second cushioning pad of a second firmness less than the firmness of the first cushioning pad. The short chamber is fixed with the long chamber, such that side edges of each chamber are substantially mutually aligned and such that top and bottom edges of the long chamber overhang top and bottom edges of the short chamber, respectively, thereby defining overlapping volumes having a pair of handles situated therein and fixed to either of the chambers.
Abstract: A transmission system for transmitting a rotary motion input to a rotary motion output utilizing hypocycloid motion multiplication is disclosed. The system comprises an input mechanism, at least one hydraulic transmission means, an output mechanism and an output bladder linkage. The input mechanism includes a plurality of rollers that each capture at least one arcuate linkage against an inside surface of a cylindrical hub, causing the linkage to rotate as the roller traverses thereacross and compress one of a plurality of input bladders. The compressed input bladders cause an output bladder to expand to drive the output mechanism in reciprocal linear motion, which the output mechanism converts to rotational motion at the rotary motion output. The output mechanism can be located proximate to, or distal from, the input mechanism.
