An implantable orthopaedic knee prosthesis includes a femoral component that is configured to be coupled to a surgically-prepared distal femur. The femoral component has an articular side that includes a posterior femoral condyle surface. A fixation side is opposite the articular side, and it includes a posterior fixation surface that extends generally in the superior/inferior direction. The posterior fixation surface has an angled posterior cement pocket formed therein.
摘要:
A decorative column comprising a rigid center post, a plurality of pre-cast pieces with each piece having a hole extending therethrough so the pre-cast piece slides onto the center post and remains in place on the center post. Each pre-cast piece being stacked upon another pre-cast piece, the pre-cast pieces being of a predefined shape, and a compressible center core liner filling a portion of the hole of the pre-cast piece. The compressible center core including a cutout shape consistent with the cross sectional shape of the rigid center post thereby allowing passage of the center post through the compressible center core.

An articulated step system for an automotive vehicle includes a step housing attached to the vehicle frame by means of at least one standoff bracket and a tension strut extending generally downwardly from a first end attached to a vehicle body to a second end attached to the step housing. The articulated step has a stowed position generally underlying the body, and a deployed position extending generally outwardly from the body. Movement of the step may be either translational or rotational with respect to the step housing. In one embodiment, the step extends for the full length of the cab of the vehicle, and partially under a load carrying body at the rear of the vehicle.
摘要:
System and method for tracking obstacles by an autonomous vehicle. Localization sensors (i.e., sensors to measure pitch, roll, and yaw, and systems including an inertial navigation system, a compass, a global positioning system, or an odometer) detect the position of the vehicle. Perception sensors (e.g., LIDAR, stereo vision, infrared vision, radar, or sonar) assess the environment about the vehicle. Using these sensors, locations of terrain features relative to the vehicle are computed and kept up-to-date. The vehicle trajectory is adjusted to avoid terrain features that are obstacles in the path of the vehicle.
摘要:
A rake with grasping heads for facilitating the collection of lawn debris. The rake with grasping heads includes an elongate inner rod being disposed in the interior of an outer housing. A first rake head extends from the bottom end of the outer housing and has a plurality of tines. A second rake head is pivotally coupled to a lower portion of the outer housing and has a plurality of uniformly spaced tines. The lower portion of the outer housing is rotatably coupled to the upper portion of the outer housing. The lower portion is rotatable between a first and a second position. The second rake head rotates with the lower portion of the outer housing. The second rake head is positioned behind the first rake head when the lower portion of the outer housing is in the first position. The second rake head faces the first rake head when the lower portion of the outer housing is in the second position. The second rake head is pivotable between an open position and a closed position. The second rake head is spaced apart from the first rake head when the second rake head is in the open position and is positioned towards the first rake head when the second rake head is in the closed position.
