A non-mechanical gimbal system is presented. The gimbal system includes a gimbal housing, including hemispherical and annular caps, rotatable sphere, and at least two curvilinear actuators. The hemispherical cap is attached to the annular cap in a removable fashion so as to surround the rotatable sphere. The curvilinear actuators are disposed between the rotatable sphere and gimbal housing. Curvilinear actuators rotate the rotatable sphere, via shear induced motion, with respect to the interior surface of the gimbal housing. The present invention has immediate applicability within security devices, games, toys, weapons (including guidance systems and aiming), and communication systems.

A power control circuit is presented. The circuit includes a pair of parallel optocoupler/logic stages and a pair of parallel voltage-to-current driver stages electrically coupled to a halfbridge stage in the order described. An input signal is communicated to the optocoupler/logic stage and processed therein to produce two distinctly separate but complimentary waveforms. Complimentary waveforms are communicated to the voltage-to-current driver stage to drive a paired arrangement of JFET switches. Thereafter, the JFET switches communicate with the halfbridge stage to control function of BJT switches. BJT switches are sequenced to produce a high power output. The present invention has immediate applicability to power conditioning, control, and distribution systems, as well as other applications which include or rely on silicon power transistors.
