Abstract: A system and method is provided for generating a multi-dimensional contextual platform that may be used to manage, diagnose, and communicate with patients in a medical practice. In particular, the system may provide a website that may provide dynamic, avatar-based interfaces that include a doctor interface and a patient interface. A doctor may create a subscription with an operator of the website in order to find new patients and view patient health records across multiple dimensions. A patient may create a subscription with the operator to locate a doctor and maintain open communications with the doctor. Once subscribed, the doctor and patient may use the website to enhance the overall healthcare experience by using social networking aspects of the website to facilitate doctor and patient communication in real-time.

Abstract: A frame structure mounts two side-by-side steps which are pivotally connected to the frame structure for up-and-down motion. The up-and-down motion of each step is translated to rotary motion by a first and second pulley. The first pulley is connected to the first step by a strap which has one end connected to the strap and the other end connected to the first pulley. The second pulley is connected to the second step by a second strap which has one end connected to the second step and the other end anchored to the second pulley.

Abstract: A frame structure mounts two side-by-side steps which are pivotally connected to the frame structure for up-and-down motion. The first step is connected, via a strap, to a first pulley, the strap being wrapped around the pulley. The second step is connected by a second strap to the second pulley and the second strap is wrapped around the second pulley. A shaft extends between the first and second pulleys and the first pulley is connected to the shaft when the pulley rotates in one direction but is not connected to the shaft when it rotates in the other direction. The second pulley is, likewise, connected to the shaft when it rotates in the same one direction but is not connected to the shaft when the pulley rotates in the other direction. The resistance element of the apparatus is an electromagnetic brake which includes a rotatable armature, and the rotary motion of the shaft is transmitted to the armature by a planetary gear arrangement.

Abstract: The exercise bicycle includes pedals and a fly wheel, and the axes of the pedals are spaced from the axis of the fly wheel. A pedal sprocket is mounted on the pedal shaft for rotation with the pedal shaft, and a fly wheel sprocket is mounted on the transmission system in operative engagement with the transmission system. A chain connects the two sprockets. The rotary motion transmission system, which is operatively connected with the fly wheel sprocket, comprises a planetary gear arrangement.

Abstract: A frame member has a seat mounted thereon, the seat being movable therealong. The frame member also carries feet rests. A shaft is mounted across the frame member at one end thereof, and a flywheel is mounted on the shaft. A planetary gear system having a rotatable carrier, pinion gears mounted in the carrier, a stationary ring gear and a central gear is mounted on the shaft for rotatably driving the flywheel. The central gear is mounted on the shaft for rotation therewith. A spool is mounted on the carrier for rotation therewith. A cable is wound around the spool for providing rotary motion to the spool when the cable is pulled by an exerciser during the rowing stroke. Thus, the rotary motion of the spool is transferred to the flywheel through the planetary gear system and the shaft in a speed increasing mode.
