Granted: 1997-04-22
Abstract: A moving picture display apparatus comprises a main body and an external memory detachably mounted on the main body.  The main body of the moving picture display apparatus is provided with a video data memory for storing therein graphic data of characters which constitute objects.  A program data memory of the external memory has object data of an object to be displayed on a raster-scan type monitor, i.e., color pallet data, object name data, vertical position data, horizontal position data, object size selection data and size designation data and etc., all of which have previously been stored therein.  Object data of an object to be displayed during the next vertical period is read from the program data memory so as to be stored in an object attribute memory.  An inrange detection circuit makes a decision as to whether or not an object is in an inranged state, based on the vertical position data, the size selection data and the size designation data, and also makes a decision as to whether or not the object is in the inranged state, based on the vertical position data, the size selection data and the size designation data.

Title: Rectilinear photokeratoscope
Inventor: SHIMMICK JOHN
IPC: A61B3/107
Filed: 1992-10-15
Granted: 2003-12-16
Abstract: A rectilinear keratoscope for determining the curvature of the anterior corneal surface of an eye. The keratoscope includes a translucent sheet having a curved pattern in the shape of a grid of intersecting individual curved lines. The pattern forms a substantially rectilinear grid image when reflected from a curved surface having a known radius of curvature.    Deviations from a spherical surface can be qualitatively and quantitatively determined from examining the nature of the reflected image pattern and by measuring the spatial frequency of grid lines lying between a reference point and an image point corresponding to a point on the surface of the cornea whose refractive power is to be measured.

Title: Sod roll stacker
Inventor: SCHOUTEN BEN H
IPC: A01B45/04
Filed: 1993-05-05
Granted: 2004-02-10
Abstract: A sod roll stacker assembles sod rolls on a platform member to form an approximately square layer of sod rolls. When the layer is complete, the platform is removed allowing the layer to fall on a support member below the platform. The platform is then moved to its former position. The above cycle of operations is repeated. The support member is rotated about a vertical axis through about 90° after each cycle so that a stack of rolls is built up having the axis of the rolls in each layer at about 90° to the adjacent layer, thereby increasing the stability of the stack.

Inventor: LEE SIMPSON
IPC: E05F3/08
Filed: 1993-06-16
Granted: 1996-06-11
Abstract: A door accessory, such as a door hinge, includes a hydraulic retarding device for cushioning the closing action of a door.  The hydraulic retarding device has a cylinder body which confines a fluid receiving space to receive hydraulic fluid therein.  One end of a piston rod extends into the fluid receiving space and has a valve unit provided thereon.  The valve unit includes a piston which is formed with perforations and which forms a clearance with the cylinder body and a valve ring which is loosely sleeved on the piston rod. The piston rod is operably associated with the door movement so that the valve ring does not block the perforations on the piston during a door opening action, thereby permitting faster fluid flow inside the fluid receiving space and providing little or no resistance to the movement of the piston rod, and so that the valve ring blocks the perforations on the piston during a door closing action, thereby permitting fluid to flow only through the clearance so as to retard the movement of the piston rod.

Title: Apparatus and method for monitoring contact pressure
Inventor: RINCOE RICHARD G
IPC: A61B5/103
Filed: 1992-05-21
Granted: 2000-08-15
Abstract: An apparatus (10) and method for monitoring pressure between the surface of a body part and a contact surface employ a plurality of pressure sensors (20) disposed in a matrix array between the contact surface and the body part. The sensors (20) produce analog force signals proportional to pressure, and a monitor receives the analog signals. A computer processor receives the output signals from the monitor to create a force profile for the sensor array. This monitoring apparatus (10) and method is used, for example, to fit prothetics, to monitor bed-ridden and wheelchair-bound patients, to reduce pain and sores caused by uneven distribution of pressure and to monitor pressure between a cast (90) and a person. The sensors (20) may be mounted on a single sheet (22) or on strips for positioning along the body, and monitoring is accomplished by multiplexing and digitizing the analog force signals.
