A golf mat having an artificial grass area with a flat portion and a hill formed in the flat portion. The distance from the top of the hill to the top of the flat portion is at least one half of the length of the blades of grass that make up the grass surface. A second grass surface having grass shorter than that in the first grass surface is separated from the first grass surface by a grass-free area, suitable for advertising.

An improved skating machine, wherein the improvement involves the incorporation of flexible components including (1) identical first and second pedal connector flexible bars rotatably connected at one respective one to a respective first and second longitudinal pedal bar and rotatably connected at their respective opposite end to a crank axle; (2) a resilient tension means connected at one end to the crank axle and connected at its opposite end to a post which is attached to a portion of a centr...

This invention describes an exercise machine which is operated in a manner similar to paddling a Kayak or other water craft with a double blade paddle. The device incorporates a "T" bar shaped handle assembly centrally positioned in front of a seated operator and connected at its base with an articulating joint to a torque resisting mechanism. The articulating joint allows the operator to manipulates the handle bar in a pattern similar to that of paddling a Kayak as this configuration allows the...

A practice device to enable children to simulate skateboarding in a safe manner so the children can practice sliding the practice device on a surface and balancing themselves on the device. The device comprises a center section, a front section and a rear section where the front and rear sections are at an angle to the center section and the bottom surface of the device is entirely smooth to facilitate the movement of the device on a surface. The upper surface of the device has a lowered interio...

A skin structure in a doll providing simulated body temperature by fluid circulation comprised of two layers separated by studs forming passageways between said layers for the circulation of fluid of the desired temperature to impart on the surface of the doll a temperature approximating body temperature. The controlled temperature fluid may be provided in a reservoir so that the fluid can be circulated to and from the skin structure. The outer skin layer is preferably resilient. The studs are a...

A control apparatus is provided for a hydrostatic transmission to simulate a gear drive on a tractor. The hydrostatic transmission has a swashplate that is angularly movable to a plurality of positions, and a proportional valve that provides a control pressure to a servo piston to control the hydrostatic transmission swashplate position. A transmission control lever may be moved to a plurality of positions, each position providing a different voltage signal to a microcontroller. The microcontrol...

This machine cuts and provides large panels, as plywood, hardboard or similar materials, on one side to provide a large panel having a flat back surface and a profiled front surface, said front surface characterized by a plurality of longitudinally extending, side by side, slightly inclined flat surfaces separated by approximately perpendicular ledges or shoulders of narrow width, thereby imparting to the panel the appearance of lap siding when applied to the exterior wall of a building. This ma...

A four pivot linkage to simulate head/neck kinematics. The linkage has a ch-roll link which rotates about a first pivot fixed in an upper body and which secures the lower end of a neck link in a second pivot. The upper end of the neck link is secured in a third pivot fixed in a yaw-pitch link which in turn articulates about a fourth pivot fixed in a head.

An oil painting is simulated by gluing a photograph onto a textured surface, rolling the photograph with a nubby roller to force portions thereof into the voids of the textured surface and sealing the photographic surface thereafter in a manner to simulate an artist's brush strokes.

A circuit to simulate the polarization relaxation phenomenon of the ferroelectric memory. The circuit has a MOS transistor, a ferroelectric capacitor, a capacitor, and a relaxation voltage source. The gate of the MOS transistor is coupled to a word line and the source of the MOS transistor is coupled to a bit line. A first electrode of the ferroelectric capacitor is coupled to the drain of the MOS transistor and the second electrode of the ferroelectric capacitor is coupled to a plate line. A fi...
