| An apparatus for reducing aerodynamic resistance in an over the road vehicle is provided. The apparatus can include a frame assembly and first and second airfoils to be coupled to the vehicle by the frame assembly ahead of first and second tires of an axle assembly provided to the vehicle. The first and second airfoils each include an air deflecting surface with a convex outward portion that extends away from a leading edge that is to be directed into the airflow to transition the portions of the airflow directed toward the first and second tires outward beyond the externally exposed sides of the first and second tires. The first and second airfoils are also spaced laterally apart from each other when coupled to the vehicle by the frame assembly to define an aperture between the first and second airfoils through which at least a portion of the airflow directed toward the axle assembly is to pass while the vehicle is underway. | ||||||

| An apparatus is provided for reducing aerodynamic drag experienced by an over-the-road vehicle while underway. A frame assembly including a fastening fixture couples the apparatus to the vehicle, and a first airfoil including a first outward air deflecting surface deflects a portion of the airflow directed toward a first tire laterally outward toward an externally exposed side of the first tire. A second airfoil including a second outward air deflecting surface deflects a portion of the airflow directed toward a second tire laterally outward toward an externally exposed side of the second tire. The first and second airfoils are spaced laterally apart from each other when coupled to the vehicle by the frame assembly to define an aperture between the first and second airfoils through which at least a portion of the airflow directed toward the axle assembly is to pass while the vehicle is underway. | ||||||

| The system is designed to reduce the aerodynamic drag on the box type of trucks such as semi-trailer or full truck vans. The system consists of a series of ductwork that gathers airflow from the front of the van and conducts the flow to the rear end of the van where it is released in proportional amounts at the back end of the truck, so as to alleviate the drag. | ||||||
| 149 | Golf tee with enhanced aerodynamic drag | US11044109 | 2005-01-26 | US20060166765A1 | 2006-07-27 | Barry Holtzman |
| This invention is a golf tee having an aerodynamic drag portion with a relatively large frontal area and aerodynamic drag coefficient, an intentionally minimized mass, and a subsequent reduction in flight distance upon being struck with a golf club. This reduced flight distance coupled with the relatively large area of the drag portion makes this tee relatively easy to find. It is economically feasible, therefore, to make this tee from a virtually indestructible but relatively more expensive material such as polyurethane. The resulting tee has significantly greater operational life than conventional tees. | ||||||

| An exercise apparatus combines weight and pneumatic resistance to provide a user with options to work against either or both types of resistances. In one mode, the exercise apparatus includes a user interface, such as, for example, a weight-lifting bar, that a user can move either toward or away from a stationary portion of the user's body. A weight (e.g., a free weight plate) can be selectively coupled to the user interface. A pneumatic resistance device can also be selectively coupled to the user interface independent of whether the user interface is also coupled to the weight. The pneumatic resistance device includes at least one valve to regulate the amount of resistance that the pneumatic resistance device applies to oppose movement of the user interface in at least one direction. At least one actuator may be provided for controlling the at least one valve, the actuator being configured to be manipulated by the user while the user is in an exercise position. The apparatus can also include a trolley that moves relative to a track. The trolley can move with the user interface so as to permit various positions of the user interface relative to the pneumatic resistance device. | ||||||

| 153 | Pneumatic variable resistance rehabilitation/therapy apparatus | US631637 | 1990-12-21 | US5312315A | 1994-05-17 | Donald G. Mortensen; Gary S. Fanton |
| A pneumatic variable resistance rehabilitation/therapy apparatus for the balanced strengthening of musculature surrounding injured, weakened, and post-operative ligaments associated with the major joints of the lower extremities. In a preferred embodiment, a leg press machine is provided comprising a frame, a foot rest assembly including a foot rest pad, and a reciprocating carriage having a patient supporting bed surface thereon. A pneumatic circuit comprising a cylinder having a reciprocating piston therein, an accumulator, an air supply and a pressure regulator is provided for the variable progressive resistance against the movement of the carriage during the working stroke (where the patient straightens his/her leg(s)). The reciprocating piston rod is linked to the reciprocating carriage by a cable and pulley system to provide a longer and more physiologically tolerable working stroke. The accumulator volume, being roughly equal to the cylinder volume, supplements the system volume to provide a resistive force rate similar to a mechanical spring system. The rod end of the cylinder is also provided with a bleed valve to prevent plunger resistance due to vacuum effects during the working stroke, and a needle valve to control the return speed of the piston rod during the return stroke. An alternate embodiment provides for optional hand holds on both ends of the rehabilitation apparatus for rehabilitation of upper extremity related injuries such that the user may use either a pushing or pulling movement to complete an exercise cycle. | ||||||
| 154 | Method of reducing drag in aerodynamic systems | US943659 | 1992-09-11 | US5236155A | 1993-08-17 | Frank J. Hrach |
| In the present method boundary layer thickening is combined with laminar flow control to reduce drag. An aerodynamic body is accelerated enabling a ram turbine on the body to receive air at velocity V.sub.o. The discharge air is directed over an aft portion of the aerodynamic body producing boundary layer thickening. The ram turbine also drives a compressor by applying torque to a shaft connected between the ram turbine and the compressor.The compressor sucks in lower boundary layer air through inlets in the shell of the aircraft producing laminar flow control and reducing drag. The discharge from the compressor is expanded in a nozzle to produce thrust. | ||||||

| A pneumatic radial tire is adapted to improve or reduce the rolling resistance and simultaneously to improve the steering stability and riding comfortability against vibration during running without adversely affecting the wet performance and durability by making higher the carcass maximum width position and the carcass curvature reverse position, or enlarging the curvature of the carcass in the radially outer zone of the carcass maximum width position and simultaneously the carcass curvature reverse extent in the radially inner zone of the sidewalls so as to intentionally deviate from the naturally equilibrated configuration.A method of manufacturing a reduced rolling resistance pneumatic radial tire uses a mold for vulcanizing and forming the tire therein, which mold has a particular shape of cavity having a foot width 20-50% wider than a rim width and diverging progressively from shoulder corresponding portions to the wider foot portion of the cavity. | ||||||

| A system for linking two or more vehicles to achieve reduced aerodynamic drag while the vehicles are travelling on the road is disclosed. The disclosed system not only physically connects the vehicles but also allows the driver of the leading vehicle to monitor and control essential functions of the trailing vehicles. Preferably, the driving mechanisms of the trailing vehicles, such as throttles, brakes, and gears, are fully operational so as not to put excessive burden on the driving mechanisms of the leading vehicle. Methods for linking individual vehicles as well as streamlining the operation of a fleet of vehicles are also disclosed. | ||||||
