Abstract: Method and apparatus for restricting field of vision so as to provide a dyslexic reader physical means for narrowing field-of-sight concentration in order to prevent eye wander and aid in normal compensatory sight narrowing by the reader. The method comprises an obfuscation of the peripheral field of vision while concurrently focusing or providing clear viewing means in the centralized, enhanced narrow reading field. The aforesaid method is readily accomplished by use of either the pin-hole camera, consisting of a minute aperture in an eye-enveloping, obfuscating field or, more practically, a set of spectacles consisting essentially of opacified or defocusing lenses having with them a centralized clear field-of-vision lens, window or aperture which effectively accomplishes in both eyes of the dyslexic reader what the pin-hole aperture does for a single eye.

Abstract: Apparatus for styling a hair replacement, the apparatus consisting of a headblock, in two forms, each form presenting an edge which simulates the front hairline of the ultimate user of the hair replacement whereby the edge may be utilized in styling the hair replacement when it is placed in overlying relationship to the headblock after manufacture and for styling. In one form, the edge is created by forming a flat face on the headblock and on the other form by defining a concavity in the face area of the headblock, the concavity having an upper wall which presents an edge for use in styling. The method of using the apparatus involves utilizing such a headblock by placing a hair replacement over the scalp area of the headblock with a portion of the hair replacement extending over the edge and then styling the hair replacement and leaving a portion of the hair replacement extending over the edge after styling so that when placed upon the head of the user the hair replacement will have a natural appearance.

Abstract: A device comprising a base plate having a first array of lines displayed on the upper surface thereof and at least one generally transparent upper plate member having at least a second array of lines marked thereon. The upper plate member(s) are juxtapositionable and rotationally movable over the base plate such that the arrays of lines present on the upper plate member(s) will interact with each other and/or the array of lines present on the base plate to create a variety of moire patterns. Some or all of the base plate and upper plate members may be premarked with desired linear arrays. Alternatively, some or all of the base plate and/or upper plate members may be provided in blank unmarked form to permit the user to draw his own linear arrays thereon so as to design the create unique moire patterns. A line drawing template may also be provided to assist the user in drawing the arrays of lines on the upper and/or base plates.

Abstract: A child's holiday calendar is arranged for enabling children to visually ascertain the approach of a holiday without a reading requirement associated therewith. The calendar includes a matrix of pockets of a predetermined number to include the date of the month prior to and including the holiday date. An underlying opaque pouch is utilized for storage of various visual markers, such as candy, marking spheres, and the like, wherein a child may visually ascertain an approach of an impending holiday as the markers sequentially removed from the associated pockets. The pockets may be prenumbered, or alternatively may utilize removable date cards or fanciful figures attachable to the portion of the support sheet overlying each pocket.
