Abstract: A system to simultaneously adjust a wheel track axle width and a steering angle of an agricultural vehicle made of: an at least two variable axle assemblies, each one of the variable axle assemblies connected to a wheel set of the agricultural vehicle is provided. During the wheel track axle adjustment process of a variable wheel track axle machine the angle of each wheel is “toed-in” or toed-our depending on wheel track extension or retraction. When the wheel track axle of the machine is being extended, all wheels are commanded to “toe-out” 3 degrees to aid in the extension and reduce external forces on the wheel and axle system. When the wheel track axle of the machine is being retracted, all wheels are commanded to “toe-out” 3 degrees to aid in the retraction and reduce external forces on the wheel and axle system. Once the wheel track axle adjustment is complete all wheels return to 0 degrees for normal operation.

Abstract: This application covers the method and control apparatus for controlling the massage of a long fiber muscle or group of muscles using a plurality or array of pressure inducing elements. The apparatus is a microprocessor based controller that provides an interface for the user to interactively locate and target areas of affected muscle tissue to specifically provide a beneficial effect which alleviates pain or provides other therapeutic results. Based on the principles and disciplines of reflexology, the controller apparatus also contains certain logic to precisely control the timing and pattern of the random command signals for the activation of pressure inducing elements in a related massage apparatus.

Abstract: Apparatus for massaging the body by subjecting the body to impacts from reciprocating plungers. The plungers are secured in a flat array within a flexible pad. Each plunger has an associated solenoid device which alternately causes the plunger to project from the pad and to retract within the pad. An electrical circuit includes a power cord and plug assembly, manual controls disposed serially on the cord and plug assembly, and a controller generating operating signals randomly to the solenoids. A heating element is optionally included in the flexible pad, with a suitable controller provided among the controls.
