Abstract: The present invention relates generally to rowing machines, and, more particularly, to such rowing machines with internal environments that duplicate actual Olympic-class rowing shells in terms of both dimensions and appearance, and simulate the specific rowing motion and technique that occurs on the water.

Abstract: According to at least some embodiments of the present invention: (i) a user's non-stationary exertion is detected; (ii) a virtual terrain is provided; and (iii) the detected non-stationary exertion is normalized for the virtual terrain. This is different than any stationary exercise machines that may normalize exertion for a virtual terrain because non-stationary exertion is used. This allows the user to exercise in a non-stationary way, such as by running cross-country. Non-stationary exercise is an advantage of at least some embodiments of the present invention because users often prefer non-stationary exercise to stationary exercise. At least some embodiments of the present invention make it possible to use mapping onto virtual terrains possible even in the non-stationary context. It is further noted that the present invention uses a virtual terrain (see DEFINITIONS section), rather than a virtual course (see DEFINITIONS section) without virtualized terrain factors (see DEFINITIONS section).

Abstract: A clutch assembly including a substantially circular carrier member including a first elongated space formed therethrough, a first bias member including a first end and a second end structured to exert a bias force, and disposed within the first elongated space wherein the first end is connected to the carrier member, and a substantially circular drive cam member coupled to the carrier member including an outside surface, a first seat formed in a portion of the outside surface, and a first drive cam pin connected to the second end of the first bias member within the first elongated space. A clutch assembly including a substantially circular carrier surrounded by at least two drive cam members, and a key member, wherein the key member is at least partially positioned within a first elongated space of the carrier member and connects the first and the second drive cam members is also provided.
