Abstract: A surgical training device includes a model comprising a simulated tissue portion mounted in selectable tension onto a plurality of posts connected to a base. Each post includes at least one notch configured for retaining the simulated tissue portion. Mounting the simulated tissue portion that is in the form of a sheet in notches of different heights creates an angled installation of simulated tissue upon which surgical techniques such as cutting and suturing can be practiced in a simulated laparoscopic environment. More than one sheet can be mounted and each sheet can be mounted with selectable tension by pulling the sheet more or less as desired onto the posts. One variation includes a simulated tumor disposed between sheets, angled or wobbly posts and textured and imprinted simulated tissue surfaces to provide various levels of dynamism and difficulty for surgical skills training in a laparoscopic environment.

Abstract: Books with internal mechanization have rotary and linear drive mechanisms which displace objects along linear, non-linear, rotary and three-dimensional paths relative to the book pages are described. Spatially arranged cut-outs in the pages which correspond to the range of motion of the displaced and translated objects allow different moving objects to be viewed at different areas of the book from page to page. Battery powered drive mechanisms with push-button operation accessible from the front of the book enables easy, selective activation of the moving objects, independent of the position of the front cover and pages relative to the back cover. Belt-driven wheels provide inherent clutching action to prevent damage to the drive mechanism. Manually operated embodiments of the various drive mechanisms which produce each of the described motions are also disclosed.

Abstract: A geography teaching apparatus has two working surfaces, such as on opposing sides of a substrate such as paper. The first working surface contains graphical images representing the outlines of countries, such as in a map of a continent. The second or opposing working surface contains graphical images which are identical in size and shape to the graphical images on the first surface, and are positioned in relative positions on the second surface which are identical to the relative positions of the graphical images on the first surface. The second surface also contains text such as the names of each of the countries shown and other information about the countries. Students study the second surface in an attempt to learn the textual information, and then turn the apparatus over to the first working surface and attempt to write down all the information they studied. The relatedness of the visual images reinforce the teaching process and improve memory retention.

Abstract: A learning aid is disclosed which has particular benefit in the teaching and learning of a foreign language. To allow the reader to become accustomed to full phrase translation, as opposed to word-by-word translation, text and associated graphics are provided on a page. A transparent overlay contains a translation of the page text, positioned on the overlay on an opaque background in register with the wording translated. With the overlay lifted, the reader sees only the text in its original foreign-language version. After translating, the reader can lower the overlay to compare his or her efforts with the provided text.

Abstract: The specification discloses a new and improved greeting card comprising a first translucent panel having indicia thereon and a second panel connected to the first panel and with an opening which defines an image thereon. The translucency of the first panel and its arrangement relative to the second panel is such that upon disposition of the first panel closely adjacent to the second panel in an overlay fashion, the image on the second panel is relatively indistinctly visible through the first panel in conjunction with the indicia on the first panel to enhance and supplement the experience associated with viewing the indicia.

Abstract: An educational training device in which a plurality of transparent sheets and base sheets are secured in fixed registry onto a top surface of a frame. A student can trace patterns shown on the base sheets onto the transparent sheets. The student can also remove and/or rearrange any of the sheets to thereby study the different interrelationships between the patterns. In addition, a top transparent sheet can be marked upon to draw a pattern that is extrapolated from the data provided by the underlying sheets.

Abstract: Display equipment gives a representation of a three-dimensional body. A series of spaced apart panels (28) are mounted to a support structure (30). Each panel (28) carries representations (40) of parts of the three-dimensional body which occur in the plane occupied by the panel. The panels are transparent or open to allow the representations carried by the different panels to be simultaneously viewed by light passing through the panels, thereby giving the effect of seeing the three-dimensional body. The equipment can be used to give a three-dimension view of the interior structure of human or animal bodies by providing cross-sectional representations of the body on the panels.

Abstract: This invention relates to a book-sized, self-contained analog computer, organized to enable an inexperienced person to program readily a differential equation. In this computer permanent circuits are either exposed or indicated as solid lines. Connections between terminals available for patching by the user are shown as dashed lines, so that with the aid of an instruction manual even a beginner can implement quickly a differential equation at the first try.Being small in size, this computer can be placed beside a student's computation sheets to be used for checking solutions arrived at by other means. Because components are inserted by the user without soldering, a user can modify a circuit quickly to suit his needs.
