| 20080312045 | VARIABLE STRIDE EXERCISE DEVICE - The variable stride exercise device utilizes various configurations of linkage assemblies, cam members, and other components, connected with a frame to allow a user to dynamically vary the user's stride path during exercise. The exercise device allows for a foot engagement member travel path that adapts to the change in stride length rather than forcing the user into a fixed size path. A user's exertion level may have several components impacting the stride length provided by the machine, such as leg power, torso power, and (in versions of the exercise apparatus with arm supports or exercise components) arm power. The exercise device may include a lockout device that selectively eliminates the variable stride features of the exercise device and allows the user to exercise in a stepping motion. | 12-18-2008 |

| 20120088637 | EXERCISE BICYCLE WITH MECHANICAL FLYWHEEL BRAKE - An exercise bicycle including a frame supporting a wheel such as a flywheel. A brake assembly (or resistance assembly) including a brake arm is pivotally coupled with the frame. The brake arm assembly includes a brake pad engaging the flywheel to alter the power needed to rotate the flywheel during exercise. A brake adjustment assembly is operably coupled with the brake arm. The adjustment assembly includes a shaft rotatably supported on the frame and mounted to be translated toward the flywheel while being restricted from translating away from the flywheel. A spring is positioned between the threaded shaft and the brake arm whereby rotation of the shaft increases or decreases compression of the spring thereby increasing or decreasing a frictional force between the brake pad and the flywheel. | 04-12-2012 |
| 20120088638 | EXERCISE BICYCLE WITH MAGNETIC FLYWHEEL BRAKE - An exercise bicycle including a frame supporting a flywheel. A magnetic brake assembly includes a brake arm pivotally mounted to the frame and including at least one magnet. The magnet is positioned adjacent to the flywheel and not in contact with the flywheel, the position of the magnet relative to the flywheel inducing a magnetic braking force on the flywheel. The pivot of the brake arm is positioned such that a pivot force vector induced on the brake arm by the magnetic braking acts to pivot the brake arm away from the flywheel. | 04-12-2012 |
| 20120122633 | EXERCISE BICYCLE FRAME WITH BICYCLE SEAT AND HANDLEBAR ADJUSTMENT ASSEMBLIES - An indoor cycling device including a unique frame arrangement with fore and aft adjustable seat and handlebar assemblies. The assemblies support a seat and handlebars for fore and aft movement. The assemblies may include a receiver with an elongate aperture with a slider positioned therein. The slider defines a first channel receiving a moveable member. A handle is operably coupled with the member to move the member within the channel in a first direction or a second direction such that a frictionally coupling is caused between the slider and the receiver when the slider is moved in the first direction and releases the coupling when the slider is moved in the second direction. | 05-17-2012 |
| 20120214646 | APPARATUS, SYSTEM AND METHOD FOR POWER MEASUREMENT - A power measurement device, which may be mounted to an inside area of a crank arm, includes processing circuitry within a housing. The processing circuitry is coupled with strain gauges mounted on the crank arm, and produces a power value that is wireless transmitted to a separate display that may receive and display power measurements. The housing may include a mounted portion and a cantilever portion where the mounted portion houses the processing circuitry and the cantilever portion houses batteries supply energy for the processing circuitry and other features. | 08-23-2012 |

| 20100005876 | THERMAL FLOW METER - A thermal mass flow controller or mass flow meter having a novel sensor housing that reduces heat conduction from the housing mounting plate or base to the sensor itself. The housing also greatly minimizes the thermal gradient that can result from the uneven application of heat to the housing base. This reduction is accomplished in part by the use of one or more thermal isolation slots to isolate the upper portion of the housing (which holds the sensor) from the lower portion of the housing. Heat transfer to the sensor housing is also minimized by raising the middle portion of the bottom of the housing so that thermal contact is made between the base and the housing only at the two ends of the housing. | 01-14-2010 |
| 20100049461 | MASS FLOW CONTROLLER WITH IMPROVED DYNAMIC - A system and method of compensating for pressure variations in a flow controller entails the use of the compressibility of the gas being controlled to provide a more accurate measurement of the flow. | 02-25-2010 |
| 20110191038 | MASS FLOW CONTROLLER WITH IMPROVED DYNAMIC RESPONSE - A system and method of characterizing or controlling a flow of a fluid is provided that involves a sensor conduit and a bypass. A plurality of fluids may be utilized in the flow control device based on characteristic information of the device generated during calibration thereof. The characteristic information, in turn is based on a dimensionless parameters, such as adjusted dynamic pressure and adjusted Reynolds number. | 08-04-2011 |

| 20090078055 | METHODS AND APPARATUS FOR PRESSURE COMPENSATION IN A MASS FLOW CONTROLLER - Performance of mass flow controller may be vulnerable to pressure transients in a flow path to which the controller is coupled for the purpose of controlling the fluid flow. A system and method are provided for reducing or eliminate performance degradations, instabilities, and/or inaccuracies of a mass flow controller caused by changes in the pressure environment. In particular, a method and system are provided for compensating for pressure transients in the pressure environment of a flow path and mass flow controller. | 03-26-2009 |
