A vibration dissipating sports glove for use in holding a bat while hitting a baseball having an energy-absorbing front pad between the index finger and the thumb. The glove also has a back padding covering the metacarpal portion of the hand and may furthermore have knuckle padding for covering the middle knuckle of each of the fingers. By using padding in a discriminate fashion, only in areas of the hand most vulnerable to impact and vibration, the glove maintains adequate flexibility and feel while, at the same time, protects the batter from bat-induced vibration and, furthermore, from pitched balls which may hit the batter's hand. Additionally, the front pad conforms between the batter's hand and the bat to provide to the batter a more secure grip upon the bat.

The invention relates to a multidimensional dynamic active variant flapping wing aircraft, which comprises a fuselage, flapping wings, an empennage, an actuation system and a control system. The multidimensional dynamic active variant flapping wing aircraft mainly imitates complex deformation of pinion bones in a flight flapping cycle. The flapping wing variant mechanism in the actuation system includes a wing skin, a humerus strut, a radius strut, an ulna strut, a metacarpus strut, a variant steering engine, a variant pull rod, and hinges between the struts. The variant mechanism and a flapping wing up-and-down flapping mechanism run synchronously under the control of control system program. When the flapping wings flap downward, the flapping wing front edge skeletons are in a flat unfolding state, the flapping wing area is increased, and the lift force is increased. When the flapping wings flap upward, the flapping wing front edge skeletons are in a multi-fold and spanwise contraction distortion state, the flapping wing area is decreased, and the damping force is reduced. In every flapping cycle, dynamic variant flapping of the flapping wings is realized, thereby realizing high efficiency flight imitating big birds.
