Provided is a power generating apparatus using piezoelectric elements, which can increase an amount of electricity generated in the piezoelectric elements and can extend the life of the piezoelectric elements. The power generating apparatus includes: a plurality of piezoelectric elements; a main body in which the piezoelectric elements are received and fixed, with spaced apart from one another, so as to protect the piezoelectric elements; a piezoelectric element support reciprocatingly installed in the main body to support the piezoelectric elements such that the piezoelectric elements are deformed by a reciprocating motion of the piezoelectric element support; a driving unit provided in the main body to operate the piezoelectric element support; and a power transmission unit connecting the driving unit to the piezoelectric element support, such that the piezoelectric element support is reciprocated by a driving force of the driving unit.

An improved orthopedic device and method for correcting spinal curvatures of a patient by specific stabilization of the patient's pelvis and spine and then exercising the spine through active range of motions. The inventive method of spinal curvature correction re-educates the patient's muscles, ligaments, and nervous system which collectively are responsible for maintaining spinal posture, to properly maintain the spinal column in a desired alignment.

Improved automatic gain control for an amplifier is obtained by controlling the size of a null zone in a drive signal for the amplifier. The size of the null zone is controlled by estimating strength of an interference signal, and dynamically varying the size of the null zone based on the estimated strength of the interference signal. As a result, the amplifier rarely saturates, regardless of signal strength. The invention is useful to reduce the harmful effects of jamming or interference.

The present invention provides an improved semi-automatic pistol magainze. In one embodied form, the unique pistol magazine member comprises an apparatus on which one end is compatible with a conventional piston magazine receptacle and the other is contoured to wrap snugly around the back of the holder's hand. The inventive magazine thereby provides the holder with the advantages of both greater bullet storage capacity and also greater compactness of bullet storage space. Moreover, the magazine chamber hugs the hand within the inner periphery of its contour thus providing the holder with added support and stability of grip. Also, in its presently preferred form, the magazine has the advantage of a relatively centrally disposed center of gravity which is conducive to greater balance and therefore better aim.

A system bus architecture for intermodular communications is disclosed. The system bus architecture comprises a backplane bus with associated memory and a plurality of control registers. A master system processor module is coupled to the backplane bus via a master bus controller. The master system processor module contains a central processing unit in selective communication the master bus controller. A plurality of slave modules are also coupled to the backplane bus via respective slave bus controllers. Each of the slave modules has a slave central processing unit in selective communication the slave bus controller. The master and slave bus controllers are in selective communication with the bus memory, the plurality of control registers, and the respective central processing units, to transmit and receive data through the backplane bus.
