摘要： A modular and scalable system configured to generate a topology platform for training, entertainment, gaming, living, working, acting, viewing, etc. The platform can have a plurality of movable columns that are extendable and retractable. In some embodiments, some of the columns can be retracted to allow users to walk on the columns while other columns can be extended to form a barrier (e.g., wall) or form an inanimate object (e.g., table). The system may be used in furniture to provide topologies for highly customized support structure designs to accommodate varying body shapes, sizes, and individual comfort levels. The system may be used to generate topologies for greenscreen film stages to provide post-production editing, compositing with actors, stuntmen, and video, etc. The platform can be configurable and re-configurable to change the objects and features of the topology and represent different or dynamic environments at any time.

摘要： A construction teaching set for education. A polyhedral block body has first and second divided members and provided by engaging and assembling of the first and second divided members. Each of the first and second divided members has a rectangular plane, a plurality of rectangular inclined surfaces adjoining sides of the rectangular plane, triangular connectors formed between the adjacent rectangular inclined surfaces, and a plurality of vertical skirts extending from the plurality of rectangular inclined surfaces and the triangular connectors. A connection bar has a protruding fastener at one end or both ends to be selectively connected to one among a first fastening hole passing through the rectangular plane, second fastening holes passing through the plurality of rectangular inclined surfaces, and third fastening holes formed in a pair of the vertical skirts adjoining each other. A coupling unit generates coupling force for the first and second divided members.

摘要： A slope measurement and drawing aid (100) for teaching mathematics having unique indicia (130), rational-numeric slope values (184), and mathematical information (192), and a method of identifying the correct rational-numeric slope value associated with the graph of a given line, either by means of a gravity-activated indicator arm (140), or by means of the orientation of the teaching aid. For instructional purposes, when used in a classroom setting, the teaching aid can be removably held on a vertical board by magnetic (240R) or other means. When used in an individual setting, a smaller version of the teaching aid can similarly be used in a horizontal orientation on paper.

摘要： A computing appliance for geometric planimetry is provided, comprising a container, a vertical dividing rule, a horizontal dividing rule, a horizontal point line and a middle point line. A fluid is filled into the container, and the vertical dividing rule, the horizontal dividing rule, the horizontal point line and the middle point line are configured on a same instructing surface of the container and arranged on each of the periphery surrounding like a rectangle. When the container is vertically disposed, a fluid level is aligned with the horizontal point line. And, when the container is tilted to form at least one angle, an area of at least one geometric shape can be derived by employing the vertical dividing rule, the horizontal dividing rule, the horizontal point line and the middle point line.

摘要： A tension compression structural unit and method of assembling structures that comprises endwise interlapping configuration of at least three elongate members into a tension compression structural unit whereby tensegrity is maintained by tensioning a first end of each elongate member against respective first ends of each other elongate member, in interlapped array, and then anchoring each second end of each elongate member—either onto a ground surface or by interlapped configuration with additional elongate members. A stable, domic structure is thus erectable without the need of additional tensioning elements such as wires or cables, for example.

摘要： The New Trigonometer is a device used to compute the trigonometric sine, cosine and tangent of angles. Consequently, the device could also be used to calculate the reciprocal sine, cosine, and tangent functions. The device constitutes of a protractor and a graduated ruler attached thereof. An arm is pivotally joined to the center of protractor and a second graduated ruler is pivotally joined to the arm in a way, which makes the New Trigonometer a reflection of the trigonometric circle.

摘要： Techniques for teaching geometric proof problems are described. According to one approach, the geometric proof application displays a geometric proof problem and a set of connectable nodes in an initial arrangement. A user then rearranges the set of connectable nodes and connects them using one-way connections to generate a solution. The geometric proof problem is solved if the user-generated solution indicates the correct logical ordering of the set of connectable nodes as determined by the geometric proof application.

摘要： The present invention provides a teaching aid system (10) for assisting students in applying trigonometric classroom lessons in real life applications both in indoor and outdoor settings. The teaching aid system consists of a pivoting scope (16) and an asymmetrically weighing gravity dial (18) that are pivotally mounted to a pair of support members (12). A tape measure (42) and an arithmetic electronic calculator (46) are attached on the support members (12) to enable students compute trigonometric formulations and applications of the same, when utilizing the system for real life objects either in indoor or outdoor settings. For determining dimensions of viewed objects, the student determines the distance from the viewed object using the tape measure (42), and the angles between the top and bottom of the viewed object using the scope (16) and gravity dial (18). Then applying the proper trigonometric formulae from a booklet or other conventional trigonometric formulae sources, the student can determine the height, elevations or slopes of objects.
