Abstract: ADAPTIVE CONTROL SYSTEM                          ABSTRACT A method of adaptive control for use in a controlled system having an adjustable forward loop gain and a control system apparatus for carrying out the method are disclosed. The control system measures the value of a parameter which is to be controlled and generates an error signal by comparing the measured valve of the parameter with a desired valve. The error signal is squared and the time derivative of the squared error signal is obtained. The control system compares the length of time that the derivative so obtained has a positive value to the time it has a negative value to obtain a gain control signal, and applies the gain control signal to the forward loop gain. The gain control signal reduces the adjustable forward loop gain until a preselected margin of stability in the controlled system is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE An image generator for generating two-dimensional images of three-dimensional solid objects at a high speed defines a scene to be displayed within a cuboid three-dimensional universe which has been hierarchically subdivided into a plurality of discrete volumes of uniform size and similar orientation. The three-dimensional universe is represented by a tree structure having a plurality of nodes, one for every volume in the three-dimensional universe which is at least partially occupied by objects in the scene. A user selects a point of view for viewing the object. Nodes in the tree structure representing the three-dimensional universe are visited in a sequence determined by the point of view selected by the user so that nodes corresponding to volumes which are unobstructed by other volumes are visited first. Each visited node enclosed by the object is projected onto a subdivided view plane organized into a hierarchy of a plurality of discrete areas. Areas of the view plane which are completely enclosed by the projection are painted onto a display screen. Areas which intersect but are not enclosed by the projection are further subdivided to locate those areas which are enclosed. A representation of the hierarchically-subdivided view plane arranged in a tree structure is stored. Each time an area of the view plane is painted, an entry in the representation of the view plane corresponding to that area is marked. The corresponding entry in the representation of the view plane is checked before an area is painted, to ensure that no area is painted more than once so that hidden surfaces are not displayed. To create sectional views, a user may define a region of the three-dimensional universe, and volumes outside of that region are not projected. Real time image generation wherein calculations necessary to create the image are performed by hard-wired digital logic elements to increase speed performance is possible.

Granted: 1988-12-13
Abstract: A drain closure that has all the advantages of and none of the disadvantages of both hand and foot tub closures. A post (24) which is threaded into the bottom of the strainer body (10) receives a stopper (41) which moves up and down on the post (24) to open or close the drain. A metal spring (38) carried by the post (24) exerts a frictional force against the stopper (41) interior sufficient to hold the stopper (41) open and enhance its sealing ability when closed. The stopper (41) can be closed by hand or foot. The stopper (41) cannot be removed without first removing the stopper knob (60). Out of sight under the stopper (41) is an integral collar which receives an open end wrench which permits tightening of the stopper knob (60) to a point where stopper (41) theft is virtually eliminated.

Abstract: PARALLEL CYLINDER INTERNAL COMBUSTION ENGINE            ABSTRACT OF THE DISCLOSURE          The  engine  disclosed  herein  comprises a number  of  pairs  of pistons, the two pistons in each pair acting in unison. The pairs are  arranged  parallel  to each  other,  and  the   pistons  are positioned parallel to and in a circle around the mainshaft which has  a cam lobe located at a convenient part of the mainshaft and encircling  the  mainshaft.  The cam lobe has  opposite  surfaces which  have  sinusoidal rises and dips  and are in  contact  with pairs of bearings attached to connecting rods.  The bearings  are on opposite sides of the cam lobe,  and at one time are driven in one  direction  by one of the two pistons in each pair  and   at another  time  in the opposite direction by the other  piston  in that pair,  the two pistons of that pair being connected to  each other  by  the  same connecting rod carrying the  bearings  which press  against the cam lobe.  The pressure exerted first  by  one bearing  and then by the opposite bearing in concert with similar thrusts  from  other  pairs of bearings  and  pistons,  causes  a steady, even rotation of the shaft on its linear axis. The action of  the  pistons  and  bearings is arranged  and  timed  so  that pressure against the surface of the cam lobe exerts vector forces against the curved surface of the cam lobe to effect rotation  of the main shaft. Centerline thrust of the bearings against the cam surface  and special design of the cam surface to avoid  friction or  binding between the bearings and the cam are special features of  this engine.  The pistons may be driven by combustion  fuels, including  gasoline,  diesel,  etc.,  and may also be adapted  to steam operation.     Pat 6076/BBB
