Abstract: Certain aspects of the present disclosure provide an amplifier for signal amplification. Certain aspects further describe methods and apparatus for applying overload protection for such amplifier. For example, one method generally includes detecting an overload condition of an amplifier based on a signal at a node of the amplifier, and controlling a parameter of an input signal of the amplifier such that the parameter of the input signal is maintained below a threshold based on the detection of the overload condition. The parameter of the input signal may include, for example, a voltage level or a duty cycle of the input signal.

Abstract: A Baseball/Softball Training Method and Device Therefor is disclosed. Also disclosed is a device that enables users to experience a very realistic batting practice withouth the high cost associated with an automated pitching machine. The device is low cost and very small in profile. The device further does not require any pitching skill in order to provide a very realistic hitting experience. The game using the device further includes a novel ball that is smaller and much softer than a conventional baseball. Finally, the ball may have holes formed in a portion of its cover to permit the user to create controllable differential drag on one side of the ball when launched to the batter.
