In embodiments of animation using keyframing and projected dynamics simulation, an animation object is displayed with handles associated with object regions for the animation object, each handle being selectable for setting animation constraints on an object region. An animation simulator receives a user input designating a particular handle with an animation constraint, and sets the animation constraint on the particular handle for the associated object region. The animation simulator also receives another user input, designating a timing of the object region associated with the particular handle of the animation object through multiple frames in an animation sequence. The animation simulator projects a simulation of the animation object utilizing a projected dynamics algorithm that applies physics to simulate the set of object regions of the animation object in the animation sequence, the simulation including simulating the object region associated with the particular handle based on the timing and the animation constraint.

A pedal-driven exercise machine is designed for an exerciser in a seated position to do pedaling. The pedal-driven exercise machine is equipped with a main body portion, a crank unit that is rotatably supported by the main body portion, a pedal unit that is rotatably supported by the crank unit, and a foot space securing unit that secures a foot space at a foot of the exerciser by retreating the pedal unit from the foot of the exerciser when the pedal-driven exercise machine is out of use.

A post-mountable exercise apparatus includes an exercise device, a 3-walled bracket and a bridge. The exercise apparatus is attachable to a post by surrounding the post with the 3-walled bracket and bridge, which tighten together in place on the post. The exercise device has a frame that supports a horizontal shaft rotatably mounted in the frame such that two crank arms extending outside the first side and the second side of the frame can be rotated to turn the horizontal shaft. A band tensioning device using a threaded member may be added so that tightening or loosening the threaded member causes a change in the tension of the pliant band and resistance of the exercise device to being rotated.

A golf club head includes a metallic section, a polymeric section, and an adhesive material. The metallic section defines an opening and the polymeric section extends over the opening. The adhesive material is disposed between the metallic section and the polymeric section to form an adhesive joint therebetween. The adhesive joint has an adhesive retaining strength configured to inhibit the polymeric section from being detached from the metallic section when the adhesive material is at least partially cured. The metallic section and the polymeric section are also mechanically engaged with one another to form a mechanical joint therebetween having a mechanical retaining strength configured to inhibit the polymeric section from being detached from the metallic section. The adhesive retaining strength of the adhesive joint, alone, is greater than the mechanical retaining strength of the mechanical joint, alone, only when the adhesive material is at least partially cured.
