摘要:
A selectively adjustable, portable exercise system with first and second resistance mechanisms, each with a rotatable spool, a cord wrapped around the spool, a handle secured to the cord, and a resistance stack formed by plural resistance packs, which can be modular. The spool and the resistance pack have engagement patterns. Each resistance pack presents a resistance to rotation, such as by a coil spring. Each of a plurality of keys has a rod portion with an engagement pattern with a spool engagement pattern to lock the spool relative to the key and a resistance pack engagement pattern for locking one or more resistance packs relative to the key and the spool. The resistance pack engagement patterns of at least some of the keys vary to lock different combinations of resistance packs relative to the key and the spool. A belt, base platforms, or both can form a retaining structure.
摘要:
A portable exercise apparatus retention mechanism with a base platform, an exercise apparatus retainer, and at least one extendible and retractable retaining structure fixed to the base platform with first and second end portions for engaging first and second opposed surfaces when at least one of the end portions is extended. A sub-panel can be secured to the base structure with a central portion of the retaining structure disposed therebetween. The retention mechanism can retain an exercise apparatus, such as a speed bag. The end portions can have contoured flanges. A supplementary engaging mechanism with extended and retracted positions can project laterally from the base platform. The supplementary engaging mechanism could comprise first and second members pivotally coupled to the base platform.

A magnetic device includes a write element including a write element tip, and a conductive coil for carrying a write current to induce a first field in the write element. A first conductor proximate a trailing edge of the write pole tip is operable to carry a first assist current to generate a second field that augments the first field. A second conductor proximate a leading edge of the write pole tip is operable to carry a second assist current to generate a third field that augments the first field. First and second side shields are on opposing sides of the write element in a cross-track direction.

A transducing device includes a writer having a pole tip region and a heater circuit. The heater circuit has a heating portion and a heater current return path. The heating portion has at least two branches positioned with respect to the writer so that current flowing through the at least two branches heat the writer. The heater current return path is electrically connected to the at least two branches of the heating portion near the pole tip region and includes an electrically conductive portion of the writer.
