| 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 |

| 20100030388 | MULTI-GAS FLOW DEVICE - 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. | 02-04-2010 |

| 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 |

| 20110153084 | Method and Apparatus for Blending Process Materials - A method and apparatus for blending and supplying process materials. The method and apparatus are particularly applicable to the blending of ultra-high purity chemicals, the blending of abrasive slurries with other chemicals for the polishing of semiconductor wafers, and high-accuracy blending of chemicals. The apparatus may include a dispensing subsystem that supplies process materials to a mixing subsystem where they are blended with a static mixer. The method may include supplying process materials with a dispensing subsystem and blending the process materials in a static mixer. | 06-23-2011 |

| 20110284652 | MULTI-PHYSICS FUEL ATOMIZER AND METHODS - A fuel atomizer that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices. | 11-24-2011 |
