| 20090272955 | TENSION GUARDRAIL TERMINAL - In accordance with a particular embodiment of the present invention, a terminal portion of a guardrail safety system includes a terminal portion of a guardrail beam having a downstream end and upstream end. The terminal portion of the guardrail beam slopes from a height appropriate for redirecting an errant vehicle to a height proximate the surface of the ground at an upstream end of the terminal portion. Support posts are installed adjacent a roadway in spaced apart relation to one another and are coupled to the terminal portion of the guardrail beam. A terminal support post is installed adjacent the roadway at an upstream end of the end terminal. The terminal support post couples to an upstream end of the terminal portion of the guardrail beam by a resistive, tensile coupling that maintains tension in the terminal portion of the guardrail beam. The resistive, tensile coupling is maintained between the terminal support post and the guardrail beam during an end-on or re-directive impact by a vehicle. However, the resistive, tensile coupling between the terminal support post and the guardrail beam is released during a reverse-direction impact. | 11-05-2009 |
| 20090272956 | GUARDRAIL SAFETY SYSTEM FOR DISSIPATING ENERGY TO DECELERATE THE IMPACTING VEHICLE - In accordance with a particular embodiment of the present invention, an end treatment of a guardrail safety system includes a terminal portion of a guardrail beam that has a downstream end and an upstream end. The terminal portion of the guardrail beam slopes from a first vertical height appropriate for redirecting an errant vehicle to a second vertical height proximate the surface of the ground at an upstream end of the terminal portion of the guardrail beam. A flattening portion forms a channel through which the terminal portion of the guardrail beam is disposed. A vertical dimension of the channel is greater at a downstream end of the flattening portion than at an upstream end of the flattening portion. An impact plate is connected to the flattening portion for engaging an impacting vehicle at an end of said guardrail beam. During an end-on impact, the impact plate and the flattening portion are advanced longitudinally along the guardrail in a downstream direction by the vehicle. The advancement of the impact plate and flattening portion dissipate energy to decelerate the impacting vehicle. As downstream portions of the guardrail beam are forced into the flattening portion, the guardrail is flattened vertically. | 11-05-2009 |
| 20100275515 | ENERGY ABSORBING SYSTEM - An energy absorbing system having a stanchion, a linearly extendable energy absorber coupled to the stanchion, a net coupled to the energy absorber, wherein the net transfers force to the energy absorber, and a securing mechanism that maintains tension between the net and the energy absorber until acted upon by tensile forces of at least a minimum threshold force, wherein at least a portion of the system is retractable into the ground. | 11-04-2010 |
| 20110057160 | Tension Guardrail Terminal - A terminal portion of a guardrail safety system includes a terminal portion of a guardrail beam having a downstream end and upstream end. The terminal portion of the guardrail beam slopes from a height appropriate for redirecting an errant vehicle to a height proximate the surface of the ground at an upstream end of the terminal portion. | 03-10-2011 |

| 20100120549 | GOLF SWING TRAINING DEVICE - The golf swing training device of the present invention includes a base positioned on the floor or ground in front of a golfer. A leg extends pivotably upward from the base. An arm is pivotally attached to the leg and extends forwardly toward the golfer. A frame is provided on the arm, with an extension member extending pivotally forwardly from the frame. The leg, frame, and extension member are each adjustable to accommodate various heights and postures of different golfers. The device can also be used with both right-handed and left-handed golfers. In use, the golfer views the golf ball through the frame and swings the golf club through a proper swing plane with hands passing beneath the extension member without contact. | 05-13-2010 |

| 20120112999 | Force Feedback System Including Multi-Tasking Graphical Host Environment - A force feedback system provides components for use in a force feedback system including a host computer and a force feedback interface device. An architecture for a host computer allows multi-tasking application programs to interface with the force feedback device without conflicts. One embodiment of a force feedback device provides both relative position reporting and absolute position reporting to allow great flexibility. A different device embodiment provides relative position reporting device allowing maximum compatibility with existing software. Information such as ballistic parameters and screen size sent from the host to the force feedback device allow accurate mouse positions and graphical object positions to be determined in the force feedback environment. Force feedback effects and structures are further described, such as events and enclosures. | 05-10-2012 |

| 20100178139 | ELECTROSTATIC END EFFECTOR APPARATUS, SYSTEMS AND METHODS - Systems, apparatus and methods for transporting substrates between system components of an electronic device manufacturing system are provided. The systems and apparatus include an electrostatic end effector having a base, an electrode pair on the base, and spacer members for spacing the substrate from the electrode pairs to provide a gap between the electrode pair and the substrate. Methods of the invention as well as numerous other aspects are provided. | 07-15-2010 |
| 20100280654 | SUBSTRATE PROCESSING SEQUENCE IN A CARTESIAN ROBOT CLUSTER TOOL - A method and apparatus for processing substrates using a multi-chamber processing system, or cluster tool, is provided. In one embodiment of the invention, a robot assembly is provided. The robot assembly includes a first motion assembly movable in a first direction, and a second motion assembly, the second motion assembly being coupled to the first motion assembly and being movable relative to the first motion assembly in a second direction that is generally orthogonal to the first direction. The robot assembly further comprises an enclosure disposed in one of the first motion assembly or the second motion assembly, an actuator within the enclosure, and a fan assembly disposed in the enclosure that is adapted to generate a pressure within the enclosure that is less than a pressure outside of the enclosure. | 11-04-2010 |
