Abstract: According to an example aspect of the present invention, there is provided a method for manufacturing a microelectromechanical system, MEMS, device, comprising: forming at least one cantilever from a highly doped silicon layer on a buried oxide layer, the at least one cantilever having a first sidewall and a second sidewall, wherein the first and second sidewalls are perpendicular to the interface between the highly doped silicon layer and the buried oxide layer; growing a lead-free piezoelectric layer at least on the first sidewall and the second sidewall; and depositing electrically conductive material at least on the lead-free piezoelectric layer on the first sidewall and the second sidewall in order to form a first electrically conductive layer on the lead-free piezoelectric layer on the first sidewall and a second electrically conductive layer on the lead-free piezoelectric layer on the second sidewall.

Abstract: A batter swing training harness and associated kit including a belt adapted to being affixed about a wearer's waist, a vertical portion extending downwardly from the belt and terminating in a looped portion adapted to being affixed about the wearer's upper leg and a first pair elastic bands extending from vertically spaced locations of the belt and vertical portion. A second individual elastic band extends from a further location of the belt. Each of the first pair of bands and the second individual band terminate in a ring adapted to being slidably supported upon a stem extending from a knob end of a bat.

Abstract: The present invention discloses a pitcher training device having an outer tube and a telescopically displaceable inner tube. A ball is secured to a projecting end of the inner tube. The user grips the outer tube with a non-throwing hand and concurrently grips the ball with a throwing hand. A forward throwing and release motion is then exerted upon the ball, concurrent with rotation of the outer tube, causing the ball and inner tube to outwardly displace relative to the outer tube.
