20100132120 | Adaptive Seat Cushion Having A Pressure-Relieving Structure - A seat cushion system includes a seat cushion assembly and at least one supplemental pad attached to a portion of the seat cushion assembly. The seat cushion assembly and the at least one supplemental pad include chambers that may be filled with a fluid to provide isolation between a user and a wheelchair or other seating structure. | 06-03-2010 |
20120138376 | MIDWHEEL DRIVE WHEELCHAIR WITH INDEPENDENT FRONT AND REAR SUSPENSION - A wheelchair includes a frame, and a front pivot arm pivotally mounted to the frame at a front pivot point, the front pivot arm having a caster for supporting the frame. A rear pivot arm is pivotally mounted to the frame at a rear pivot point, the rear pivot arm having a caster for supporting the frame. A ground engaging mid-wheel drive wheel is connected to the frame. A linkage connects the front and rear pivot arms to each other in a manner such that an upward or downward rotation of one of the pivot arms about its pivot point causes rotation of the other pivot arm about its pivot point in an opposite rotational direction. | 06-07-2012 |

20100140445 | ROTOHAMMER SUPPORT AND ACTUATION DEVICE - A device for the support and linear movement of a rotohammer. The device includes an elongated shaft, pole or rail having a first end, and a second end, the latter proximate to an object to be drilled and having a longitudinal axis. An L-shaped bracket is provided having a first leg slidably mounted on the elongated shaft, pole or rail along its longitudinal axis and a second leg projecting perpendicularly from the first leg, the L-shaped bracket being sized to receive and support the rotohammer. A handle is pivotable on the elongated shaft, pole or rail and a linkage bridging the handle and L-shaped bracket is movable by movement of the handle such that in moving the handle from a first at rest position to a second position, the L-shaped bracket is caused to move along the elongated shaft, pole or rail toward its second end for extending the rotohammer in the direction of the object to be drilled. | 06-10-2010 |
