摘要： A handheld counter is provided having a housing forming an opening, and inner sheath, an engagement member, and a sensor. The inner sheath is located in said opening and movable relative to the housing. The inner sheath forms a cylindrical cavity for receiving a writing instrument. The engagement member is connected with the inner sheath and frictionally engages said writing instrument upon insertion of said writing instrument into said cavity. The sensor is positioned to detect movement of said inner sheath and generate a signal in response to movement of said inner sheath.

摘要： A fraction exploration device for teaching various mathematical principles related to fractions, comprising a base sheet having printed indicia thereon, a ruler attached pivotally to the base sheet. The printed indicia on the base sheet include intersecting grid lines which define a matrix of intersections and a series of parallelograms therebetween. Fractions are located at a plurality of the intersections of the grid lines, each fraction having a numerator, a denominator and a dividing line separating the numerator from the denominator. The dividing line of each fraction is sloped to represent a mathematical relationship of the numerator to the denominator.

摘要： A portable and foldable teaching aid combines an abacus and an inclined writing surface. The abacus helps teach math skills and the inclined writing surface helps strengthen hand and wrist muscles that are used in writing. The abacus and writing board are positioned in physical proximity to one another to encourage children to write down math problems on the writing board, to solve them on the abacus, and to write down the answer on the writing board. The writing board may be of the dry erase type, the chalkboard type, or any other suitable, erasable writing surface. It may also be magnetized to hold letters, shapes, and the like. The writing board is releasably attached to support rods so that it can be separated from them when the device is folded for storage. When folded, it can be carried separately or placed into a child's backpack.

摘要： The elastic pattern abacus relates to educational counting devices for learning basic number and arithmetic concepts. The present invention introduces a new flexible medium for threading and holding counters (beads or blocks of any shapes) in a sequence, such that: they slide easily, yet are automatically held stably at any desired positions along the sequence. The members of the abacus can be separated, counted, grouped, divided, and regrouped to demonstrate arithmetic concepts and number systems. A tool for changing the arrangement of the abacus beads is also disclosed.

摘要： A method and apparatus for plotting a boat's position relative to a rhumb line when tacking. The apparatus includes three independently rotatable disk members. A first disk member presents a compass rose, the second of the disk members presents an indicator that aligns on the compass rose along with a grid, and the third of the disk members presents a rhumb line. The starting and ending positions are plotted on the rhumb line. The rhumb line is then aligned with the compass rose in accordance with the boat's true course. An initial course is set by rotating the indicator with respect to the compass rose on the first disk. The boat's first tack position is located and plotted on the grid by counting grid lines from the starting position. The second disk is then rotated and the next tack position is plotted away from the first tack position. The tack positions are plotted on the third disk to provide the boat's position relative to the rhumb line.

摘要： A logic design slide rule comprises, in a preferred embodiment, front and rear cover plates coupled together; interior slide channels formed between the covers; and a plurality of slides disposed between the covers and able to move horizontally from left to right within the channels. The slides may be moved to display indicia on beams for observation through a single column of truth-table windows and to display corresponding indicia printed on interior slide plates for observation through an array or grid of K-map windows, which column and grid of windows are located in the front cover of the slide rule. Indicia are also displayed through a set of output variable slots, preferably in the rear cover. Operation of the preferred slide rule will aid the designer to obtain a minimum set of combinational logic functions for up to four input variable from a given truth-table.

摘要： A slide rule for selecting bearing materials has a base plate, a fixed cursor having first, second and third portions spaced apart from one another and fixedly attached to the base plate, a first sliding ruler slidably mounted between the first and second portions of the fixed cursor, an indicator cursor having an indicator cursor line and fixed to the first sliding ruler, a second sliding ruler slidably mounted between the second and third portions of the fixed cursor, and a fixed ruler mounted on the opposite side to the second sliding ruler with the third portion of the fixed cursor interposed therebetween. The fixed cursor has a fixed cursor line in the vicinity of its left end. The first sliding ruler has logarithmic graduations which indicate levels of bearing surface pressure. The second sliding ruler has logarithmic graduations which indicate sliding speeds, PV values and periods of lifetime of various bearing materials. The fixed ruler has graduations which indicate bearing temperatures and on which correction factors in respect of bearing temperatures and information on various bearing materials are indicated. The slide rule is manipulated on the basis of given values of bearing surface pressure and sliding speed to provide information on a PV value of a bearing, a lifetime of a bearing material, regreasing time, danger limits, attention limits, safety limits and so forth.
